    The present invention relates to a cosmetic method of modifying the appearance of the eye contour and an associated disc and kit. Foundations
    Countless people seek to modify the appearance of the contours of their eyes, particularly to beautify their appearance, for example, by applying recognized or personal aesthetic criteria, in order to change the appearance of their appearance or, in fact, correct one or more imperfections, particularly the asymmetry between the eyes, for example, one being more closed than the other.
    Others may seek to restore the appearance of the contours of their eyes to how they used to be when they were younger. A particular consequence of aging may be the fall of the fixed upper eyelid, sometimes to the point that it partially overlaps the movable upper eyelid when the eye is open. This phenomenon is often associated by observers with the aging of the person and is generally perceived as being undesirable.
    Finally, certain people may also wish to modify the shapes of their eye contours due to their dimensions, for example, an eye being too closed or too open, too large or too small, or having an unwanted protruding appearance.
    It is also known to apply makeup compositions to the eye contour, particularly to emphasize all or part of the eye contour in color. However, eye makeup has several disadvantages. It often serves to emphasize the eyes, but does not affect the shape of the eye contours. It is particularly difficult to restore asymmetry and it is practically impossible to look younger. Additionally, the shading created by applying makeup is not desired by many people, particularly men, children, the elderly and certain women. Applying makeup also requires a certain amount of skill in order to apply it effectively. In addition, it is often necessary to take certain precautions in order to maintain a makeup result over time, particularly to avoid any rubbing or washing, and the makeup usually lasts only a few hours, or at most a day or two, so you need to be repeated regularly.
    It is possible to modify a person's appearance by using plastic surgery. However, most people would prefer not to have to resort to plastic surgery, as this solution is often perceived as being very radical and is often painful. Additionally, plastic surgery does not achieve a more youthful aspect and is appropriate, above all, for important corrective purposes, being unsuitable for minor corrective purposes or merely to satisfy the desire to change the appearance of the eyes.
    It is known to apply elongated flat strips to the upper movable eyelid in order to form an artificial fold in the eyelid. Such strips are used particularly by people of Asian origin in whom the movable upper eyelid has a palpebral fold that is less marked than for the eyes of people of Caucasian or African origin, for the purpose of making the appearance of an Asian eye stand out. approach that of a Caucasian or African eye. However, this phenomenon hardly occurs in Caucasian or African eyes, and as a result, this solution has no effect on these types of eyes.
    United States Patent No. 4,854,307 describes the application of a liquid adhesive composition for bonding the movable upper eyelid and the fixed upper eyelid. The adhesive has the disadvantage of being uncomfortable and dangerous for the user, and does not allow the appearance to be modified or corrected in a precise and suitable way for all users.
    United States Patent No. 6,190,346 and international application WO 01/34078 describes the application of a flat adhesive strip over the movable upper eyelid in order to correct the fall of the fixed upper eyelid. This solution does not allow the eye contour to be modified in a way that is as efficient and comfortable as it would be desirable, since the strip is not adapted to the topology of the eyelid on which it is applied. resume
    There is a need to remedy at least some of the disadvantages mentioned above.
    In particular, it is desirable to be able to modify the appearance of the eye contour in a way that is attractive, simple, long-lasting, efficient, reversible and adapted to all types of eyes, whether Caucasian, Asian or African.
    There is also a need to find a solution that is suitable for the adaptation of all types of people, particularly of any age, without causing unattractive and undesirable skin folds.
    In general, the invention relates to the use of a disc, also referred to as an aesthetic prosthesis.
    Exemplary modalities of the invention thus provide a method for cosmetically modifying the appearance of the eye contour, the method comprising the step consisting of the application of at least one disc on the movable upper eyelid, the application face of the disc having a non-flat shape predefined with multidirectional curvature, or at least one disk made of a material suitable for responding to stress by deformation in an inelastic manner so as to take a multidirectional curvature over the eyelid and retain that curvature when the tension ceases.
    The term "multidirectional curvature" should be understood as curvature in at least two distinct planes, for example, mutually perpendicular planes, for example, a longitudinal plane containing the longitudinal axis of the disc and a transverse plane perpendicular to it.
    In exemplary embodiments of the invention, the method thus comprises: • a step consisting of applying at least one disc to the upper movable eyelid, the application face of the disc having a predefined non-flat shape with double curvature before application; and / or • a step consisting of the application of at least one disc on the movable upper eyelid and of modifying at least one curvature of the disc after application, the disc tending by plastic deformation to preserve the shape in which it is placed, regardless of the eyelid mobile top.
    The term “double curvature” should be understood as meaning that the application face of the disc has a shape showing at least two curvatures around at least two distinct axes, particularly two mutually perpendicular axes, for example, a curvature around a longitudinal axis and another curvature around a transverse axis! the disc.
    By means of the invention, the disc applied to the movable upper eyelid can present a shape that is better adapted to the shape of the movable upper eyelid, thus, making it possible to simultaneously provide comfort while the disc is being worn and to facilitate the use of the disc, depending on the needs of each person.
    The invention can reduce the risk of folds forming, even when applied to skin that is thin or old, or even if applied very quickly. The disc can thus be applied more easily and without great care.
    The ergonomics of disk usage can also be improved and adapted to each individual. As a result, the disc can be put in place and removed quickly and instinctively. For example, there is less risk of placing the wrong face of the disc on the movable upper eyelid.
    In addition, the curvature of the disc may make it easier for the disc to adhere to the movable upper eyelid, thus making it possible, in some circumstances, to secure the disc without using an adhesive, for example, merely by surface tension, or using an adhesive having low adhesive power. . This can make it easier to remove the disc, it can irritate the skin less, it can stay better in place over time, and / or it can make it easier to replace the disc over the movable upper eyelid.
    The disc can be of rigidity and / or thickness that vary, for example, in order to obtain better effects in the lifting of the fixed upper eyelid, for example.
    The disc can be pre-formatted and / or pre-formatted so that its application face adapts at least partially to the shape of the movable upper eyelid.
    In particular, the disc may have an application face of a format that is selected, prior to application, as a function of the upper upper eyelid topology.
    For example, the adhesive can be formatted in a factory, or at the point of sale, or at the place of use, when cutting, machining, molding, compressing, hot forming or otherwise. The final format of the disc before being placed in place can optionally be provided by a formatting machine made available to the user of the disc.
    In a variant, the disc may have an application face, prior to application, which is independent of the shape of the movable upper eyelid, and the disc may be able to take a shape that fits that of the movable upper eyelid after application, and then keep this shape after application, regardless of the movable upper eyelid. In other words, once its shape is provided on the application face, this shape can be preserved even in the absence of the eyelid. For example, the disc may have plasticity that allows it to deform in contact with the eyelid with the deformation to which it is subjected to being inelastic.
    A plurality of discs of different sizes and / or formats can be available to the user, for example, presented in common packaging, and the user can select from among those discs whose disc is most suitable for the desired effect. The user can proceed by successive approaches or under the guidance of an expert. Where appropriate, the packaging of the discs may include one or more models, for example, serving to assess the curvature and / or the dimensions of the eyelid, for example, curvature in a horizontal plane and curvature in a vertical plane.
    The disc can be stretched in shape. For example, the disk may have a “half-moon” or “crescent-moon” shape in longitudinal section, with its contour in longitudinal section being formed, for example, by the union of two non-concentric circular arches, optionally both concave in the same side, optionally both having the same radius. Thus, the disc contour, in longitudinal section, can correspond to join two circular arcs that are concave on the same side and with different radii, the circular arches corresponding significantly to the application face and the external face.
    In longitudinal section, the disc can also have a shape that is substantially rectangular, triangular, semi-elliptical, parabolic or semicircular.
    The disc may have a length that is substantially equal to the width of the movable upper eyelid and a width which is substantially equal to the height of the movable upper eyelid, but other dimensions are possible. The application face of the disc can optionally cover substantially the entire surface of the movable upper eyelid. The disc may optionally have a shape that is symmetrical around a plane of symmetry or an axis of symmetry. The height of the disc preferably occupies more than a third of the height of the movable upper eyelid, and more preferably more than half of the height of the movable upper eyelid.
    Before application, the application face of the disc can have a predefined non-flat shape with double curvature, or in a variant, it can have an application face that extends in a plane before application.
    When the application face of the disc is of a predefined non-flat shape with double curvature before application, said application face is concave towards the eyelid. The application face of the disc may have at least one spheroidal portion, particularly a portion that is spherical, ellipsoidal, paraboloid or hyperboloid.
    The application face of the disc, and particularly its spheroidal portion, can have a radius of curvature ranging from 1.2 cm (cm) to 1.6 cm.
    The application face of the disc can have double curvature, each of its curvatures presenting a curvature of radius varying between 1.2 cm and 1.6 cm, being possible that the radii of curvature are different.
    The application face of the disc, and particularly its spheroidal portion, may have curvature that is determined by a given geometric function, for example, a function that is spherical, ellipsoidal, paraboloid or hyperboloid, or in a variant, may have a curvature that it is not determined from a geometric function. In particular, its curvature can be adapted to the shape of the movable upper eyelid, for example, to the shape of the eyelid of an individual to whom the disc is applied, to the shape of an individual's eyelid used as a reference, to the average shape of the eyelids of a person. plurality of individuals, or indeed the shape of an eyelid that corresponds to a standard of beauty.
    The application face of the disc, and particularly the spheroidal portion, can include at least two non-coplanar plane facets, preferably at least six non-coplanar plane facets. The shape and / or at least one curvature of the application face of the disk can be dimensioned as a function of the dimensions of the facets and the angles formed between the normal ones for said facets.
    The thickness of the disk, particularly in the spheroidal portion, and as a measure between the application face of the disk and the external face of the same opposite the application face can vary between 1 micrometer (pm) and 1 millimeter (mm), and preferably vary between 5 pm and 200 pm.
    The thickness of the disc and / or the stiffness of the disc may vary along at least one axis of the disc, for example, the longitudinal axis of the disc, or along an axis that is perpendicular or oblique to the longitudinal axis of the disc . The disc may have resilience that varies as a function of the disc's position, for example, associated with the variation in disc thickness.
    The thickness of the disc may vary as long as the disc stiffness is constant. In a variant, the thickness of the disc can vary, for example, by the use of reinforcement elements, while the thickness of the disc is constant.
    The thickness and / or stiffness of the disc may be less in its central portion than at the edges of the disc, particularly at the longitudinal ends of the disc. In a variant, the thickness and / or stiffness of the disc may be greater in the central portion than at the edges of the disc, particularly at the longitudinal ends of the disc.
    The thickness and / or stiffness of the disc can vary monotonically, for example, decreasing or increasing, from one end of the disc to the other or from the middle of the disc towards the longitudinal ends of the disc.
    The disc may exhibit periodic or regular variations in thickness and / or stiffness, from one end of the disc to the other, particularly from one longitudinal end to the other.
    The disc may have at least one localized zone of thickness and / or stiffness that differs from the rest of the disc, and particularly from one longitudinal end to the other.
    Particularly in its spheroidal portion, the hardness of the disk can vary between 200 kilopascals (kPa) to 200 gigapascals (GPa), and preferably vary between 1 megapascal (MPa) and 10 GPa.
    Between at least two zones of the disc, its stiffness can vary by a factor of at least 2, for example, by a factor of 5. The thickness of the disc between two zones of the disc can vary by a factor of at least 1.25, for example, by a factor of 2.
    The thickness of the disc can vary, with differences in thickness being obtained particularly by using at least two materials of different thicknesses, by adding at least one reinforcement element, by differentiating the concentration of at least one compound in the disc, and / or by different treatment of at least two areas of the disc.
    The thickness of the disc can vary, with different thicknesses being obtained, for example, by molding the disc in a mold of varying thicknesses, by machining the disc to obtain varying thicknesses, by adding and / or removing material, by localized compression, and / or by printing in three dimensions.
    The stiffness and / or thickness of the disc can be modified after application to the eyelid, particularly by applying pressure, by the relative movement between at least two component parts of the disc, particularly by the movement of at least two disc blades that are movable in relation to each other, by the application of heat and / or light, for example, in order to harden, soften and / or expand the disc material in an optionally localized way (for example, by photocure, thermosetting and / or expansion of the material by the application of heat), by the addition and / or removal of material, for example, local application of one or more reinforcement elements, or by contact with predefined reagent.
    The disc can be flexible or rigid, plastic or elastic. The material, thickness and / or stiffness of the disc are appropriate to make the disc easier to handle, particularly to put the disc in place and / or remove it.
    The disk can be made of at least one polymeric material, or some other synthetic material, such as: • a polyolefin, particularly polyethylene, polypropylene, polyisoprene, polystyrene, polybutadiene, polyacrylate or polyacrylamide; • a polymer obtained by condensation reactions, for example, a polyester, a polyurethane, a polyamide, a polyurea, or some other organic or organo-mineral polymer, for example a polyether, silicone, a natural polymer such as a poliosis ( eg cellulose), a protein, or • a wax; among others.
    The disk can be made of a mineral and / or metallic material, such as: • a metal, alkaline earth, or alkaline oxide, carbide, nitride, carbonate, phosphate or sulfate, for example, calcium carbonate or calcium phosphate; • a silicate, an aluminosilicate; or • a metal or alloy based on iron, aluminum, titanium, magnesium, silver, gold or platinum; among others.
    The disc can be made of a material including natural fibers, a fabric or other woven shape, paper or other non-woven shape, wood, biocellulose, among others.
    The disc can be made of a pure material or a material mixed with some other materials.
    The disc can be made after taking markings and measurements from the user's skin, for example, by the performance of the three-dimensional (3D) acquisition of the relief of the eyelid by means of an optical or acoustic acquisition system, for example, a stereoscopic view, projection of margin, ultrasound or other system, for example, a mechanical antenna.
    The relief can be acquired in a static or dynamic way, with the eyes closed and / or with relative movement of the eyelids.
    Where appropriate, acquisition can be performed using one or more predefined discs that are positioned over the eyelid in order to determine the effect of those discs on the appearance or mechanical behavior of the eyelid.
    The disc can be cut from a base frame. For example, the base structure can be made of a plastic material. For example, the base structure can comprise one or more spheroidal shapes, particularly shapes that are spherical, from which the disk (s) is / are cut. The diameter of the spheroidal shape may be close to the diameter of the eye. In particular, the diameter of the spheroidal shape can vary between 26 mm and 28 mm.
    The disc may comprise blades of the same or different materials. For example, the disc can be made by laminating the blades together. Adhesion between the blades can be provided, for example, by electrostatic coupling or by surface tension or by the use of an adhesive. The blades can be optionally movable in relation to each other.
    The disk can be made of a material that is not homogeneous, particularly a material that includes fibers, flakes or vacuoles, gaps and / or bubbles that are stuck or that are connected together.
    The disc can be porous to oxygen, air and water vapor, so that it allows the eyelid to breathe.
    The disc may comprise an expandable material.
    The application face of the disc, and / or the opposite face of the disc, may be smooth or may have roughness, cells or roughness.
    The application face of the disc and / or preferably the opposite face of the disc, can simulate human skin, particularly the skin of the eyelid. In particular, it can have the same color, texture and / or the same relief as the skin of the eyelid before application, or a reference skin, for example, meeting certain beauty criteria. The surface of the application face of the disc and / or its opposite face can transmit a soft and velvety appearance close to that of the skin. The surface can be rough, for example, with a succession of cavities and projections.
    The disc can optionally be colored. The disc can have a single color or it can have multiple colors. The disc may have a color that is close to that of human skin. The disc can be transparent and / or translucent, allowing the skin of the eyelid to be seen through the disc. The disc can thus allow the appearance of the eye contour to be modified while being practically invisible to an observer's eyes.
    The disc may have a shiny or opaque effect. The brightness can provide the disc with an attractive effect, particularly for young people, while an opaque appearance can serve to make the disc more discreet, particularly for older people.
    The surface state of the outer face of the disc, opposite to its application face, can be rough enough to allow the makeup to adhere to the eyelid.
    Where appropriate, the disc may be provided to the user with at least one makeup that is compatible to be applied to the outer face of the disc, such makeup may, for example, be contained in the same packaging as the disc.
    The disk may have a length, measured along its long curvilinear axis, that varies between 2 cm and 3 cm. The disk can have a width, measured along its short axis, varying between 3 mm and 10 mm. The disc may have a higher dimension rate in relation to the smaller dimension other than its thickness, varying between 2 and 10.
    The disc may optionally include a recess through the application face of the disc and / or its face opposite the application face. In particular, the indentation can be a passing indent allowing the makeup to be applied directly to the eyelids, for example. Indentation can also increase comfort by making the disc better ventilated.
    The indentation can be substantially elongated in shape, particularly in the long direction of the disc and, for example, can be located close to the lashes, since it is applied to the movable upper eyelid.
    For example, indentation can allow an eyeliner to be applied directly to the movable upper eyelid. For example, the indentation can be a gap formed through the disc. The disc can serve as a stencil for applying the eyeliner. The material of the disc can be selected in such a way that the eyeliner does not remain in place on the disc. Thus, eyeliner stains on the disc are easily removed in order to leave a clear line on the eyelid.
    The indentation can also serve to insert at least some of the lashes into it, for example, to transmit the predefined curvature to it. The method for applying the disc may then include a step consisting of inserting the lashes through the indentation in the disc, possibly while using a guide.
    The disc may also not have contact with the lashes, since it is in place on the eyelid.
    The outer face opposite the disc application face may be covered at least partially with makeup, for example, makeup that is colored, shiny or opaque. As a result, the invention serves to change the appearance of the eye contour, for example, by increasing the brightness, appearance and / or color of the eyelid.
    The disc may include a colored and / or printed pattern simulating an eyeliner line.
    It can then make it possible to increase the visibility of the movable upper eyelid and contribute to improving the appearance of the eye. The shape of the application face of the disc, before or after application, can make it possible to obtain better effects, for example, compared to the application of a flat strip over the eyelid. In addition, the good behavior of the disc of the invention over time can serve to prevent the disc from becoming accidentally pinched, which would reveal an unattractive appearance on the eyelid as a result of wearing makeup.
    The outer face of the disc opposite the application face may include a zone for holding lashes and / or false eyelashes. The holding area can serve to suppress the user's lashes in order to provide them with a predefined curl. The holding area can correspond to a through slot as described above, in which the lashes can be inserted. It is also possible to position false eyelashes over the area to hold on the disc, particularly on the outer edge of the disc application face and / or on its opposite face. The holding area can be reinforced and / or can be thicker.
    In addition to modifying the shape of the eyelid, when this is desirable, there are numerous other applications for a disc of the invention.
    The disc can serve to obtain a symmetrical appearance for the eyelids of both eyes of an individual.
    The disc can also serve to mask at least partially one or more defects of the movable and / or fixed upper eyelid, such as, for example, an outgrowth, a visible vein or a birthmark.
    The disc can facilitate the application of an active eye and eyelid care agent, and may include such an active agent. In particular, the disc can be used as a reservoir for the application of a composition on the upper and / or fixed upper eyelid. For example, the disk may be made of a porous material impregnated with an active agent. For example, the disc can release an active agent for the care or growth of eyelashes, for example, bimatoprost, for anti-aging treatment of the eyelid, to provide comfort to the eye, for example, using water, a physiological liquid, an active agent against irritation, an anesthetic, an active agent against dust, among others. The active agent applied can be a cosmetic without any therapeutic action.
    The active agent can be incorporated into the disk prior to application and / or can be incorporated into the disk at the time it is applied and / or after application. The active agent can be incorporated in the position with or without solvent.
    When the disc contains an active agent, the disc can be offered to the user in a sealed package, for example, sterile packaging.
    The disc can also allow secretions to be retained, for example, sweat and / or tallow.
    The disc may also allow the movable and / or fixed upper eyelid to be protected against the effects of light, for example, sunlight, wind, and / or the intrusion of particles, for example, sand.
    The disc may include a disc pressing portion. The pressing part can be flat and connected to the rest of the disk in a flexible way, for example, through a hinge connection, on the edge of the disk. The pressing part of the disc may comprise a non-spheroidal portion. The pressing part of the disc can, for example, facilitate placing the disc in place and / or removing it. Where appropriate, the pressing portion of the disc may be defined by a removable portion of the disc. The pressing part of the disc can hold against the fixed upper eyelid.
    The disc may include a portion that is arranged to hold, at least partially, against the eye lashes in order to act mechanically, biologically and / or chemically on the lashes. The part arranged to support against the lashes of the eye can be flat and can be flexibly connected, particularly through a hinge connection, to an edge of the disc. The portion arranged to hold against the eye lashes may, where appropriate, include a slit to allow the lashes to be curved to be modified at least partially, as described above, into the area to hold the lashes and / or false eyelashes on the opposite face the application side of the disc.
    The pressing part of the disc and / or the part arranged to hold against the lashes can optionally be made of the same material as the rest of the disc, and can optionally be of the same thickness. They can be made of a material that is different from the rest of the disc, for example, be heat sealed, glued adhesive, overmolded and / or mechanically assembled with the rest of the disc.
    The disc can be manufactured by thermoforming, molding, through three-dimensional polymerization, laser etching, mechanical machining, among others.
    The application face of the disc and / or the movable upper eyelid can be at least partially coated in a compound facilitating the adhesion of the disc to the movable upper eyelid. The compound can be an adhesive, particularly a pressure sensitive adhesive (PSA). The compound can be applied before placing the disc in place, on the eyelid and / or on the disc. The compound can be applied by the user, where appropriate. The compound can also be present on the disc when it is supplied to the user.
    The adhesive powder of the adhesive compound covering at least part of the application face of the disc and / or the movable upper eyelid can be reduced by the addition of some other compound. The compound may be covered with a removable non-sticky protective film, where appropriate.
    The disc may include a non-adhesive portion defining at least a portion of the application face.
    The compound allowing adhesion of the disc to the eyelid does not need to be adhesive, for example, it can be a gel, a cream, a solvent or an oil, optionally including an active agent, and serving to transfer sufficient adhesion to the adhesive through the effect of tension superficial to hold it over the movable upper eyelid.
    Disc retention can also be increased by the appropriate selection of material and / or the shape of the disc's application face. For example, the application face of the disc may be covered with a non-slip material, for example, an elastomer.
    Where appropriate, the compound applied to the movable upper eyelid can react with the material from which the disc is made. The compound applied to the movable upper eyelid may, for example, be a silicone having reactive functions such as hydrosilylation functions or a cyanoacrylate monomer.
    Where appropriate, the compound may cover certain areas only on the application face of the disc and / or the movable upper eyelid, for example, areas located on the margins of the disc and / or the movable upper eyelid.
    Before application, the disc can be pre-formatted in several ways.
    The disc can be made of a soft material that is reformable, for example, a plastic material or a material suitable for curing.
    For example, the disc may have stiffness that varies over time, preferably increasing as a result of a stimulus, for example, radiation, the application of a liquid, evaporation, the application of heat, a chemical reaction or biological, among others.
    The disc can also be made of a material having a format memory, particularly being made in such a way that it is able to take its final shape at the time of application.
    The disk can be made of a film-forming polymeric material, for example, based on reactive silicone.
    The disc may include an extension in at least one of its longitudinal ends, the extension being for application to the cavity in the inner corner of the eye and / or in the end of the eye away from said cavity. Such an extension can allow a pleasant effect to be applied to the eye by extending the fold of the eye.
    The extension can be substantially flat and have a predefined non-flat shape. In particular, the extension can be flat when it is positioned over the cavity in the corner of the eye. Conversely, the extension may have a predefined non-flat shape, particularly a spheroidal shape, when it is to be positioned over the end of the eye that is opposite the corner of the eye.
    The extension can also be made of a material that is more flexible than the rest of the disc, particularly to facilitate positioning on the cavity in the corner of the eye and / or on the end opposite it.
    The extension can optionally be made of the same material as the rest of the disc. The extension and the rest of the disc can be shaped as a single piece.
    The extension can have a thickness varying between 10 pm and 1 mm, for example.
    Where it is connected to the rest of the disc, the extension may form a constriction in the width direction of the disc. This constriction can form a hinge, making it easier to change the inclination of the disc in the corner of the eye.
    The extension may be at least partially covered and / or may include a make-up and / or care product.
    As mentioned above, the method of the invention may include a step consisting of acquiring the topology of the eye contour prior to application of the disc. The disc can be pre-formatted as a function of the result of acquiring the topology of the eye contour.
    For example, the method can be implemented with an analysis system allowing the shape of the eye contour to be analyzed, particularly the shape of the movable upper eyelid and / or the fixed upper eyelid, and allowing the disc shape to be deduced , particularly the shape of its application face to be positioned on the movable upper eyelid, in order to obtain the desired change in the appearance of the eye contour.
    Regardless or in combination with the above, the invention thus also provides a system for analyzing the topology of the eye contour to identify the fixed upper and / or movable upper eyelid portion (s) for modification in order to approach of a standard eyelid shape, for example, corresponding to the beauty canon, a shape desired by the user, for example, corresponding to the shape of the user's eye when young or, in fact, a shape resulting from the average of evaluations performed in a plurality of people or corresponding to an age group and / or a given type of population, among others.
    In particular, the system can be configured to determine the portion (s) of the movable and / or fixed upper eyelid that is not within the curvature regularity shown by most of the movable and / or fixed upper eyelids of certain people, particularly young people.
    The system can be particularly configured to identify the portion (s) of the fixed upper eyelid that has fallen. The system can also serve to identify the indented portion (s) of the movable and / or fixed upper eyelid.
    The system can operate by simulation. Thus, it can be provided with calculation means such as a microcomputer or a server capable of simulating the rendering of the eye contour after the disc has been applied. For example, such means can operate using a database and / or logic base to apply tension to a soft body, for example.
    By comparison, the system can deduce the closest disk (s) to a target format, for example, depending on the user's wishes or depending on an appearance model.
    The system can also operate by deduction and calculation. For example, the system can deduce the shape and / or thickness of the disc, for example, to match a target format, for example, based on the user's wishes or based on an appearance model. In particular, the deduction can be performed based on the logic of stresses applied to a soft body, or based on a database, for example, derived from the experience gained.
    Preferably, the system is configured to allow the selection among the simulated disc (s) and / or calculated (s) the disc or discs that achieve the best comfort, and particularly that have the least thickness.

    Figures 1A and 1B are diagrammatic section views showing examples of relative positioning of fixed and movable upper eyelids 3 and 2 of eye 4, when the eye is closed (Figure 1A) and when the eye is open (Figure 1B).
    By comparing Figures 1A and 1B, it can be seen that when eye 4 is closed (Figure 1 A), the movable upper eyelid 2 covers the pupil of the eye.
    When eye 4 is open (Figure 1B), it can be seen that the fixed upper eyelid 3 falls so as to cover the movable upper eyelid 2, at least partially. This phenomenon, often due to the aging of the person, has an undesirable effect and it is generally desirable to be able to correct it.
    Figures 2A and 2B correspond respectively to the open and closed position of eye 4 in Figures 1A and 1B. However, a disc 1 was applied over the movable upper eyelid 2.
    Disc 1 may include a predefined non-planar application face 1a with double curvature prior to application, and / or an application face 1a which tends to retain the shape in which it has been placed, by modifying a curvature of the disk after having been applied to the movable upper eyelid 2, independently of the movable upper eyelid 2.
    Disc 1 is applied to movable eyelid 2 while eye 4 is closed. When eye 4 is open (Figure 2B), disc 1 contributes to reducing the fall of the fixed upper eyelid 3, with disc 1 allowing the modification of the relative position of the fixed upper eyelid 3 in relation to the movable upper eyelid 2 when lifting it in the direction of arrow F.
    Figures 3A to 3C show a first variant modality of disk 1. Figure 3A is a perspective view of disk 1, Figure 3B is a longitudinal AA section view of disk 1 of Figure 3A, and Figure 3C is a BB cross section view of disk 1 in Figure 3A.
    In this example, disk 1 has a predefined double-curved application face, disk 1 having a spheroidal portion, for example. The application face 1a of the disc 1 can, for example, be curved along its longitudinal axis X and its transversal axis Y.
    For example, the thickness of the disk 1 can vary between 1 pm to 1 millimeter mm, and preferably between 5 pm and 200 pm. For example, the stiffness of disk 1 varies between 200 kPa and 200 GPa, and preferably varies between 1 MPa and 10 GPa. In this example, the thickness and stiffness of disk 1 are constant, but need not be.
    The radius of curvature Rx and Ry of disc 1, as associated respectively with the axes of curvature X and Y of disc 1, can vary between 1.2 cm and 1.6 cm, for example.
    As measured along its long curvilinear axis, disk 1 may have a length L varying between 2 cm and 3 cm, and as measured along its short axis, it may have a width / ranging between 3 mm and 10 mm.
    Figure 3D shows another variant modality of disc 1 suitable for use in the method of the invention and / or serving as a model for disc 1 to be used in the method of the invention.
    In this example, disk 1 has a spheroidal portion, for example, having a plurality of flat non-coplanar facets 5.
    Figure 3E shows a second variant embodiment of a disc 1 suitable for use in a method of the invention. In this example, disc 1 is substantially flat in the shape prior to application, and has an application face 1a that tends to retain the shape in which disc 1 is placed by changing the curvature of disc 1 after it has been applied to the movable upper eyelid. 2 due to the plasticity of the disc 1, and therefore it must be independent of the movable upper eyelid 2.
    Disc 1 may have a length L ranging between 2 cm and 3 cm and a width varia ranging between 3 mm and 10 mm.
    For example, the thickness of the disk 1 can vary between 1 pm and 1 mm, and preferably between 5 pm and 200 pm. For example, the stiffness of disk 1 varies between 200 kPa and 200 GPa, and preferably between 1 MPa and 10 GPa. In this example, the thickness and stiffness of disk 1 are constant, but need not be.
    Figures 4A to 4C show the possibility of modifying the rigidity and thickness of a disk 1 suitable for use in the method of the invention, by the expansion material by the application of heat. The stiffness and / or thickness of the disc can be modified by the expansion material before or after the disc has been placed in position on the movable upper eyelid.
    Disc 1 may include an expandable material 40a present in all or part of disc 1, as shown in Figure 4A. The expandable material 40a can comprise expandable polymer beads incorporating a solvent, for example, Expansel® beads.
    A heat source C can serve to heat the disc 1 locally, for example, in a zone Z, as shown in Figures 4A and 4B, Figure 4B showing the modification obtained in zone Z after being heated.
    It is also possible to position an expandable element smaller in size than the underlying layer of the disc in order to modify the thickness and / or stiffness of the disc.
    In order to avoid or reduce the potential deformation in the thickness of the disk 1 or the potential variation in the stiffness of the disk 1 while the source C is applying heat, it is possible to make the disk 1 as at least two parts 1 'and 1 ”, for example , overlapping parts as shown in Figure 4C. The lower part 1 ”can be made so as to be insensitive to the application of heat by the source C, for example, being made entirely or partially of a material 40b that is not expandable by the application of heat, while the upper part 1 'can comprise totally or partially a material 40a that is expandable by the application of heat.
    Figures 5A to 5D show examples of discs 1 in the longitudinal section.
    As can be seen, disk 1 can have a longitudinal section shape that can be of any type, for example, optionally rectangular with rounded, triangular or semicircular edges.
    Optionally, the thickness of the disc may vary. The examples in Figures 5A to 5D correspond to discs in which the application face 1a is formatted at the time of application in variants that are not shown, the profile for the variation in thickness and in the longitudinal direction is as shown in Figures 5A to 5D, but the application face 1 curved before being placed in the suit of at least two mutually perpendicular axes of curvature X and Y, with the application face 1a being spheroidal, for example.
    Figures 6A to 6I show another variant of discs 1.
    The disk 1 may be thick and vary along a transverse Y axis of the disk 1, as shown in Figure 6A, or along a longitudinal axis X of the disk 1, as shown in Figure 6B to 6H.
    In these figures, discs 1 are shown flat, however, the description below also applies to discs having application faces that are not flat, for example, that are spherical.
    Disc 1 may show periodic thickness variation and, as can be seen in Figure 6A.
    For example routes, the variation in thickness and disc 1 occurs in the transverse direction. The variation in thickness and can give rise to longitudinal grooves being formed in order to project from the outer face 1b and / or from the application face 1a. The material density of the disc 1 may be uniform or may be greater in areas of lesser thickness, for example, as a result of the disc 1 being compressed in said areas.
    The thickness of the disc 1 can also vary monotonically, for example, increasing or decreasing, from one end of the disc 1 to the other, for example, from one end to the other, as can be seen in Figure 6C.
    Disc 1 may have a zone located 13 in thickness and which is different from the rest of the disc, as can be seen in Figure 6B, for example, a zone of increased localized thickness.
    The thickness of the disc 1 can be greater in its central portion than at the longitudinal ends of the disc, as can be seen in Figure 6H, or it can be less than the central portion than at the ends of the disc, as can be seen in Figure 6G. In this figure, an indentation 14 is formed on the outer face 1b of the disc 1. In a variant, the indentation is formed on the application face 1a.
    The disc may be thick and vary as a result of superimposing a plurality of blades 15, as can be seen in Figures 6D to 6F. These blades 15 can be fixed in relation to each other.
    The use of a plurality of blades 15, for example, two blades 15a and 15b as shown in Figure 6I, can serve to increase the stiffness of disc 1, for example. The blades can be overlapped exactly or otherwise. For example, the top blade 15a does not need to cover the bottom blade 15b completely.
    In the modalities of Figures 6A to 6I, the disc 1 may also have stiffness and / or thickness that varies along one or more axes other than the longitudinal axis X.
    Figure 7 shows the possibility of incorporating one or more reinforcement elements 6 in the disc 1 in order to modify its stiffness in one or more zones of the disc. For example, reinforcement elements 6 consist of metal reinforcement, particularly one or more cables having a diameter ranging between 10 pm and 200 pm, by reinforcement consisting of rigid materials such as hard plastics, such as polyethylene yarns or ceramic wires.
    Figure 8A is a perspective view showing the possibility of having a disk 1 that includes extensions 7a and 7b. Figure 8B is a diagrammatic face view of a disc 1 such as extensions 7a and 7b applied over the movable upper eyelid 2. Figure 8C is a diagrammatic section view showing disc 1 including an extension 7a applied to the cavity 16 of the corner of the eye.
    For example, extension 7a can be substantially flat in shape and can be designed to rest on the cavity 16 in the corner of the eye, close to the nose 17, where extension 7b can have a shape that is substantially spheroidal to be positioned on the end of the eye opposite the cavity in the corner of the eye.
    Extensions 7a and 7b can be more flexible than the central portion of disc 1. Extensions 7a and 7b can optionally be made of the same material as the rest of disc 1.
    Each extension 7a and 7b can cooperate with the disc body 1 to define constraints R and R 'in the disc width 1 respectively. Such a constriction R or R' can define an increased deformation zone facilitating the obtaining of a slope break between the disk extension and body, as can be seen in Figure 8C.
    In the examples in Figures 8A to 8C, disk 1 has two extensions 7a and 7b, but in a variant it can have only one extension 7a or 7b.
    Figure 9 is a diagrammatic perspective view showing the possibility of the disc 1 including a pressing portion 8a, for example, extending the outer face 1b opposite the application face 1a. The pressing portion 8a may have one of its edges 18 attached to an edge of the disc 1.
    The pressing portion 8a can be flat or come to rest against the fixed upper eyelid 3. In this way, the pressing portion 8a can be flexibly connected to one of the edges of the disc 1, for example, through a hinge connection, in order to so as to be able to adapt the shape of the fixed upper eyelid 3 during application.
    The pressing portion 8a can facilitate placing the disc 1 in place on the movable upper eyelid 2, and / or removing it. For example, the user can hold the disc 1 through the pressing portion 8a in order to be able to place the disc 1 in position on the movable upper eyelid 2, and / or remove it.
    Figure 10 shows the possibility of the disc 1 including a support portion 8b arranged to support at least partially against the lashes. For example, the support portion 8b can serve to act mechanically, biologically and / or chemically on the lashes, for example, to administer a care product and / or makeup on the lashes in order to modify the curvature of the lashes. eyelashes, inter alia. For example, the support portion 8b can include a slot 19 into which the lashes can be inserted at least partially, for example, in order to modify their curvature. Slit 19 can also act as the zone for connecting with the false eyelashes and / or eyelashes mentioned above for face 1b which is opposite the application face 1a of disc 1. Supporting portion 8b can be flat and connected to the rest of the disk 1 flexibly, for example, via a hinge connection. Where appropriate, the support portion 8b can also serve as a pressing portion as described above.
    Figure 11a shows the possibility of the disc 1 including an indentation 9. The indentation 9 can optionally be a through opening, and can serve, for example, to apply makeup and / or care product to the movable upper eyelid 2.
    In this example, indent 9 is elongated in a transverse direction. In a variant, and as shown in Figure 11b, indentation 9 can be elongated in a longitudinal direction and can, for example, be located close to the border of disc 1 which must be applied close to the lashes, for example, in order to allow an eyeliner to be applied or to allow the lashes to be inserted in the indentation 9, in order to repress them to have a particular curvature, as described above with reference to Figure 10.
    Figure 14 shows an example of a kit 10 of the invention.
    For example only, kit 10 comprises a disc 1 as described in any of the above modalities, and at least one container 11 containing makeup and / or an adhesive and / or an active composition, suitable for application to the application face 1a of disc 1, to face 1b which is opposite the application face 1a, and / or to the upper movable eyelid 2.
    In a variant or in combination, the kit may include an eyeglass frame and / or corrective lenses associated with disc 1.
    Figure 15 shows an example of an analysis system 20 for analyzing the topology of the eye contour in order to implement the method of the invention.
    For example, the analysis system 20 can comprise a computer 21, a printer 22 connected to computer 21 and a camera 23 allowing the topology of the eye contour to be acquired, the camera being connected to computer 21 in the same way.
    Computer 21 may be conventional and comprise a central unit 24, a screen 25 and a user interface including a keyboard 26 and a mouse 27.
    The analysis system 20 may also include a unit 30 for formatting the disk. The disk formatting unit 30 can serve, for example, to modify the shape of the application face of the disk after acquisition of the topology through the camera 23 and before the application of the disk on the movable upper eyelid.
    The analysis system 20 can be used as described above. For example, the analysis system 20 can serve to make a disk based on measurements made from the user's skin. The analysis system 20 can allow the eyelid relief to be captured in 3D by acoustic or optical acquisition, for example, by stereoscopic vision, through projection margins, ultrasound, etc., for example, through a mechanical antenna.
    The relief can be acquired statically or dynamically, with closed eyes and / or with relative movement of the eyelids.
    Where appropriate, acquisition can be performed using one or more predefined discs positioned on the eyelid in order to determine the effect of these discs on the appearance of the eye and on the mechanical behavior of the eyelid.
    Figures 16 to 18 are diagrams showing examples of steps that can be implemented in the method of the invention.
    For example routes, the method may include step la consisting of acquiring the topology of the eye contour, for example, using an analysis system 20 as described above, followed by step Ha, consisting of selecting a disc that is appropriate for the topology of the eye from a variety of available discs, and finally step III consisting of applying the disc as selected in this way to the movable upper eyelid, as shown in Figure 16.
    For example, during step Ha, the user can have a plurality of discs of different sizes and / or formats available, for example, present in common packaging, and the user can select from among these discs the disc that is most suitable for the desired effect given the results of the topology acquisition. The user can proceed by successive approaches or under the guidance of an expert. Where appropriate, the disc packaging may include one or more models serving as an example for assessing the curvature and / or the dimensions of the eyelid, for example, its curvature in a horizontal plane and in a vertical plane.
    In a variant, as shown in Figure 17, the method may comprise a step 1a consisting of acquiring the topology of the eye contour, followed by a step llb consisting of the manufacture of a disc corresponding to the topology of the eye, and finally a step III consisting of when applying the disc as manufactured in this way to the movable upper eyelid.
    For example, during step llb, the disk can be formatted at the factory, at a point of sale, or at the point of use, by cutting, machining, molding, pressing, hot forming or in some other way, as a depending on the results obtained from the topology. The final format of the disc before being placed in place during step III can optionally be given by a formatting machine made available to the user of the disc.
    In a variant, the disc may have an application face having a shape, prior to application, that is independent of the shape of the upper movable eyelid, and the user gives the disc a format that is adapted to the shape of the movable upper eyelid after it has been applied to it as a function of the results of the topology acquisition, in order to preserve that shape after application, regardless of the movable upper eyelid.
    For example, the disc can be manufactured by cutting from a base structure. For example, the base structure can be made of a plastic material and include one or more spheroidal shapes, particularly spherical shapes, from which the disc is cut. The diameter of the spheroidal shape may be close to the diameter of the eye. In practice, the diameter of the spheroidal shape can vary between 26 mm and 28 mm.
    Figure 18 shows a method of the invention comprising step 1b consisting of having at least one disc available, for example, in packaging, the optional step Ha as described above, consisting of selecting a disc adapted to the topology of the eye from a variety of available discs suitable for modifying the desired change to the appearance of the eye contour, and step III, consisting of applying the disc to the movable upper eyelid.
    In step III of applying the disc on the movable upper eyelid mentioned above, the disc can, for example, be applied with or without the aid of adhesive and / or with or without the presence of a compound, for example, an active agent, over the movable upper eyelid, on the face of the application of the disc, and / or on the face of the disc opposite to its application face. Example
    Hemispheroids were made of a transparent polyethylene terephthalate (PET) material by a blowing technique. The hemispheroids had a spherical shape with a thickness of about 10 pm and a radius of curvature of about 14 mm.
    After that, scissors were used to cut the discs of the hemispheroids, the discs being of elongated ovoid shape in longitudinal section, of length (measured along a meridian), equal to 2.5 cm, 3 cm or 3.5 cm, and of greater width (measured along a parallel) of up to 1.2 cm, and preferably of 1 cm.
    A 50% branched sulfonic polyester polymer in solution in water, type AC 1350® sold by the supplier Eastman Chemicals, was deposited on the application face of the discs.
    Figures 12 and 13 show two photographs illustrating the effect obtained on a person by using a disc 1.
    Figure 12 shows the positioning of disk 1 on the upper movable eyelid 2 of the left eye (located on the left when facing the person). Disc 1 was applied while the upper movable eyelid 2 was closed.
    The disc 1 can be held in place on the movable upper eyelid 2 with or without the use of an adhesive or using a humidifying composition, for example, a moisturizer or a gel.
    In Figure 13, you can see the effect obtained in the left eye after receiving disc 1.
    As can be seen in comparison with the right eye, the disc 1 serves to greatly reduce the fall of the fixed upper eyelid 3, such that it practically does not cover the movable upper eyelid.
    The term "comprising one" is synonymous with "comprising at least one".
