    Related Art Basic fluid lenses have been known since about 1958, as described in US Patent No. 2,836,101, incorporated herein by “10 reference in its entirety. More recent examples can be seen. in “Dynamically Reconfigurable Fluid Core Fluid Cladding Lens in a Micro fluidic Channel,” Tang et al, Lab Chip, 2008, vol. 8, p. 395, and in the publication WIPO WO 2008/063442, each of which is incorporated herein by reference in its entirety. These fluid lens applications are targeted at photonics, digital phone and camera technology, and microelectronics.
    Fluid lenses have also been proposed for ophthalmic applications. (See, for example, US Patent No. 7,085,065, incorporated herein by reference in its entirety.) In all cases, the advantages of lenses - fluid, including a wide dynamic range, ability to provide adaptive correction, robustness, and low cost, must be balanced against the limitations of the size of the opening, tendency to leak, and consistency in performance. The “065 patent, for example, has disclosed several improvements and embodiments aimed at the effective containment of fluid in the lens - fluid to be used in ophthalmic applications. The adjustment of power in fluid lenses has been carried out by injecting additional fluid into a lens cavity, by electrocoating, by applying ultrasonic pulses, and by using swelling forces in a crosslinking polymer after the introduction of a crosslinking agent. swelling in the lens fluid, such as water.

It is also currently not possible to produce fluid lenses in any desired shape other than a round shape due to complications introduced in the non-uniform expansion of non-circular fluid lenses. »BRIEF SUMMARY In one embodiment of the present invention, a non-round fluid lens assembly includes a rigid non-round lens and a flexible membrane attached to the non-round rigid lens, such that a cavity is formed between the non-round rigid lens and the flexible membrane. A reservoir in fluid communication with the cavity allows a fluid to be transferred into and out of the cavity in order to alter the optical magnifying power of the fluid lens assembly. In one embodiment, a front surface of the rigid, non-round lens is —aspherical. Additionally or alternatively, a thickness of the flexible membrane can be contoured so that it changes shape in a spherical manner when the fluid is transferred between the cavity and the reservoir. Additionally or alternatively, the flexible membrane may have an “insertion” part that is more flexible than the other parts of the flexible membrane, such that the transfer of fluid between the cavity and the reservoir causes the shape of the insertion part to change in a spherical manner without substantially modifying the parts of the flexible membrane other than the insertion parts. In one embodiment, the insertion part is in an elliptical shape. The insertion part can be contoured so that it changes shape in a spherical manner when the fluid is transferred between the cavity and the reservoir. Including such an insertion part in the flexible membrane allows a non-round lens (for example, an * oval-shaped, rectangular-shaped lens, or other shape that can be

It will be apparent to a person skilled in the relevant art that this invention can also be employed in a variety of other applications.

Furthermore, such phrases are not necessarily referring to the same embodiment.

    The limitations of the previously available fluid-charged lens technology described in the Fundamentals section above can be removed by building an aspherical fluid lens. Lenses 5 - previous fluids have always been round in shape, since there was no method for building a fluid aspherical lens. FIG. 1 illustrates an exemplary aspherical fluid lens 100 according to an embodiment of the present invention. The fluid lens 100 includes a rigid front surface 102, a flexible dorsal surface 104, and a fluid that fills the cavity 106 "10 formed between the front surface 102 and the dorsal surface 104. The surface. rigid front 102 can be provided by a rigid optical lens 108 produced from, for example, glass or plastic. The flexible dorsal surface 104 can be provided, for example, with a flat flexible membrane 110 stretched over the edge of the rigid optical lens 108. The fluid lens thus formed is connected - via a channel 112 to an aligned 114 reservoir or otherwise formed with a deformable elastomeric membrane that contains excess fluid. The fluid lens 100 and the reservoir 114 together form a sealed unit. An actuator 116 is operable to tighten or expand the deformable membrane within the reservoir to transfer the fluid between the reservoir 11 and the fluid 100 through channel 112. The actuator 116 can be, for example and without limitation, a bulb actuator, a type actuator syringe, or a marking actuator. In the embodiments, none, each, or both the rigid optical lens 108 and the flexible membrane 110 may have optical magnifying power. The channel 112, which connects the fluid lens 100 to the reservoir 114, can be housed, for example, in the eye part of a spectacle frame or parts of the temple frame.
    Throughout this disclosure, the term "fluid lens assembly" will be used to describe the assembly of the rigid front lens 108, the flexible membrane 110, and the fluid transfer system by intervention.
    The term "fluid lens" will be used to indicate the fluid layer and the two surfaces 102 and 104 that contain the fluid and that form the surfaces of the fluid lens.
    In non-circular fluid lenses, fluid pressure causes —diflective deflections of the flexible membrane along its short and long axes and thus produces a non-spherical deflection of the membrane.
    The non-circular fluid lenses of the embodiments of the present invention, therefore, correct the astigmatism created by this deflection.
    In one embodiment, the front surface of the rigid front lens corrects the astigmatism “10 caused by the fluid.
    In addition or alternatively, a thickness of the flexible membrane can be contoured to effect a spherical deflection of the membrane in response to fluid pressures.
    In one embodiment, the flexible membrane includes an insertion part that is more flexible than other parts of the flexible membrane, such that the transfer of fluid between the cavity and the reservoir causes the shape of the insertion part to change accordingly. in a spherical manner without substantially altering the parts of the flexible membrane other than the insertion parts.
    Aspherization of the front lens A fluid lens, like the fluid lens 100, can be made by providing an aspherical (rigid) front lens. Since the front lens 108 is in contact with the fluid on its dorsal surface 102, the impact of adding aspheric correction on the dorsal surface 102 of the front lens 108 will be mitigated by the fluid's refractive index relative to the material's refractive index. front lens.
    In fact, the change in - front lens thickness 108 needed to provide an aspheric correction across the dorsal surface 102 can be expressed as: dad O Eq 1) nn where d is the local change in front lens thickness required to provide a change particularly in the optical power at that point, d, is the change in thickness that would be necessary if the fluid were air, n, is the refractive index of the front lens material and n5 is the fluid refractive index. For example, if the front lens 108 is made of polycarbonate — from bisphenol A and the fluid is silicone oil, then n is 1.59 and no is 1.54, resulting in d equal to 11.8di. In other words, a relatively large variation in lens thickness will be required to provide an aspheric correction, if this correction is added to the dorsal surface 102 of the front lens 108.
    “10 The thickness of the lens can be reduced by adding an aspherical correction to a front surface 118 of the front lens 108, the front surface 118 being in contact with air. The aspheric correction on the front surface 118 can be in the form of rotationally symmetric aspheric correction, making the rigid lens surface 108 ellipsoidal or hyperboloidal. In this case, the surface can be described by Eq. 2, in which the surface is ellipsoidal if p is positive, and hyperboloidal if p is negative: À a an Eq. 2) nt = D) Rotationally symmetric aspheric corrections applied to the surface rigid lens front 118 provide at least two benefits. Aspherical corrections can be designed to minimize the spherical aberration present in the fluid lens which can be especially noticeable for high spherical magnifying powers. Additionally, the excess power of the fluid lens can be reduced at high viewing angles, compatible with the visual needs of the user.
    Toric correction of the 2 ”front lens In addition or alternatively, other aspheric corrections can be applied to the front surface 118 of the rigid lens 108. For example, surface 118 can become toroidal. The astigmatism thus added to the front surface 118 of the rigid lens 108 has at least two benefits. Astigmatism can be used to neutralize the natural astigmatism of the eye, possessed by about 80% of the population that requires vision correction. Astigmatism can also be used to counteract astigmatism - generated on the surface 104 of the flexible membrane 110 when the shape of the fluid lens deviates from a circle.
    People with natural astigmatism in their eyes typically wear astigmatism correction glasses to achieve the best corrected vision. For this correction to be applicable, the direction of the astigmatic axis "10 dalented must be orthogonal to the astigmatic axis of the eye of the spectacle wearer. : If this astigmatic correction is provided by adding a toric curve to the front surface 118 of rigid lens 108, then it is desirable to produce front toric rigid lenses 108 with the toric axis at all possible angles to the O line at 180º of the lens rigid 108. This would constitute 180 different configurations, or skus. This is because the fluid lens assembly is not rotationally symmetrical, as it includes channel 112 connected to fluid lens 100. Additionally, it is desirable to substantially match the magnitude of the astigmatic correction added to the front surface 118 of the rigid lens 108 with the magnitude of the astigmatic correction required by the user. Although the total range of magnitudes of natural astigmatism is very large (approximately 0 to approximately 15 diopters, or more), it is about 6 diopters (D) for 99% of the population that requires vision correction. Since the similarity between the natural astigmatism of the eye and the lens correction astigmatism is required to be to the nearest 0.25D, about 25 different configurations of the front surface are required to cover the above mentioned band. In addition, the connection of channel 114 to the rigid lens 108 leads to a differentiation between the left and right lenses, multiplying the total number of skus by another factor of two. Therefore, 9000 different configurations on the front surface 118 of the rigid lens 108 may be required to provide correction for 99% of the population that requires vision correction.
    In an embodiment of the present invention, it is possible to substantially reduce the number of skus over the front lens by designing an empty rotationally symmetrical lens that can be shaped or machined at high volume. The shape of the desired lens can then be cut to match the desired shape of the fluid lens, and the membrane attached to the outer edge of this shape that has been cut. A hole can be drilled in the side of the rigid lens that has been cut to provide a “10” connection to the fluid path within the channel. A small connector or a sleeve can connect the end of the channel to the hole.
    Applying a toric correction to the front surface 118 of the rigid lens 108 of the fluid lens assembly also allows for the construction of fluid lenses that are not round (e.g., oval or rectangular) in shape. Non-round fluid lenses have not been marketed because a non-round fluid lens develops astigmatic error when the fluid lens is inflated to achieve greater extra magnifying power. This is because the injection of fluid into a fluid lens causes an increase in hydrostatic pressure that is the same in all directions. This force causes —the flexible membrane (such as membrane 110) of the fluid lens assembly to stretch or protrude outward. In addition, the force makes the membrane surface more convex and gives the fluid lens a greater extra magnifying power. In the case of a non-circular fluid lens, the length of the membrane meridians is not the same in all directions. The curvature of the - membrane is therefore different on different meridians, being steeper on the shortest meridian and less steep along the longest meridian. This leads to a toric form. In one embodiment, it is possible to neutralize this inflation-induced astigmatism in the fluid lens by adding an astigmatic correction to the front surface of the rigid lens. In this approach, when the fluid lens is not inflated (that is, when it is at its lowest additional magnifying power), the lens mount has astigmatism corresponding to the astigmatism added to the front surface of the rigid lens. That is, when the fluid lens is not inflated, the astigmatism added to the front surface of the rigid lens is decompensated by any inflation-induced astigmatism. The addition of astigmatism on the front surface 118 of the rigid lens 108 allows a balance between astigmatism at the lowest extra magnifying power and astigmatism at the highest extra magnifying power. This “10 balance can be calculated and optimized for the total projected range of powers of: increasing the fluid lens. Such a balance may also be acceptable to the user, as long as astigmatism does not exceed the human eye's astigmatism tolerance threshold at any point in the range or increasing powers of the fluid lens.
    In an exemplary embodiment, a fluid lens is designed according to the parameters shown in Table 1. The front surface of the fluid lens has no astigmatic correction in this embodiment.

In this case, the degree of divergence of the round shape is expressed as the decentralization, and the shape becomes progressively more non-circular when it deviates from 1.0. The data in Table 1 show that the slight divergence of a round shape motivated the development of a relatively low amount of astigmatism (0.12D) at the highest point of the range, that is, 3.25D.
    FIG. 2 shows the dependence on the formation of astigmatism as a function of the decentralization in this embodiment of the fluid lens.
    The ordinate shows astigmatism in diopters (D), while the “10 off center (k,) was plotted on the x axis.
    In FIG. 2, line 202 represents the: embodiment of the fluid lens described in Table 1. Line 204 shows the values of astigmatism at the lowest point of the range (1.25D), while line 206 represents the highest point of the range range (3.25D). It is clear that for remarkably non-circular (ie commercially useful) geometries of the fluid lens, for example, k, <0.85, the relatively small inflation required to reach the lowest point of the magnifying power range (1.25D ) leads to a small magnitude of astigmatism.
    This astigmatism is mostly below the level of perception of the human eye (typically 0.10 to 0.12D). However, the astigmatism induced at the upper end of the increase power range reaches 0.85D in k, = 0.85, well above the tolerance range of astigmatism by the human eye when used close to vision tasks, which is typically at around 0.50D in the direct stare (that is, O º stare angle and no more than 0.75D over any part of the lens besides the 15º stare angle) AFIG.2 demonstrates the magnitude of the problem associated with non-circular fluid lenses.
    FIG. 3 shows the rate of astigmatism development in the fluid lens embodiment specified in Table 1 with an added astigmatic correction (i.e., toric correction) of 0.125D on the front surface of the rigid lens.
    Line 304, which represents the values of astigmatism at the lowest point of the range, reaches 0.125D in a 1.0-centimeter, according to the project's intention.
    Line 306, which represents the values of astigmatism at the highest point of the range, reaches the value of 0.50D in a decentralization of 0.87. Interestingly, the fluid lens astigmatism remains constant at about 0.12D over the entire magnifying power range at a 0.94 off-center. It is possible to achieve non-circular forms of lower decentralization by increasing the astigmatic correction of the front surface of the rigid lens.
    The maximum of such “10 correction should not exceed 0.18D, consistent with the visual comfort and: image quality expected by users at the lower end of the increasing power range of the fluid lens set.
    This result shows that it is possible to design fluid lenses that are moderately non-round in shape with this approach.
    Modification of the flexible membrane A fluid lens, such as fluid lens 100, can be processed aspherical by letting the membrane, such as membrane 110, inflate to adopt an aspherical (as opposed to spherical) shape. In one embodiment, an aspherical fluid lens uses a thick outline membrane to form the fluid lens.
    A membrane of uniform thickness used to form a circular fluid lens assembly in the shape inflates uniformly, thus acquiring a spherical shape.
    The local deflection of the membrane is mainly controlled by the local stiffness of the membrane, and can be altered by the hardening of the membrane or alteration of its thickness across the surface.
    A thick contoured membrane can therefore be used to form a fluid aspherical lens.
    For example, if a rotationally symmetric aspherical shape is required, the membrane must inflate in an ellipsoidal or hyperbolic shape.
    Such an inflation profile can be achieved by changing the thickness of the membrane in a radially symmetrical shape. Any superficial shape can be provided by an appropriate thickness contour on the entire membrane surface, as can be determined by a person skilled in the art.
    o Deformation of the elastic membrane is provided by an overlap of elongation and curvature. The stiffness in general is proportional to the modulus of elasticity. For the strain elongation part, it is also proportional to the thickness of the membrane, the curvature part is proportional to the thickness in cubes. One method of adjusting the stiffness involves “10 adjusting the membrane thickness along specific guidelines. The thickness of the membrane can be changed by various methods, for example, by a stretching process that is orientationally specific. Another method is to deposit a layer of a coating of varying thickness, such as through a plasma deposition process. As illustrated in FIGS. 5a, b and 6a, b, another method is to adhesively attach a second strip of membrane of appropriate thickness along a given membrane meridian. Such methods place a minor limitation on the shape of the glasses containing the fluid lens mechanism, since any shape can be analyzed by an approach based on the finite element, the effective “long” and “short” axes identified, and then the variation the thickness applied along these axes. Alternatively, a solution can be derived from the stiffness as a function of x, y coordinates of the membrane, and this stiffness matrix can be produced by depositing a relatively rigid coating, such as silicon oxide (SiOx).
    23 The design of a flexible membrane with location-dependent stiffness may require computing the: mechanical response of the membrane in an oval fluid lens, surface geometry acquired by the membrane as a result of such deformation or stretching, and the optical power of a lens fluid that includes a membrane with the resulting shape, all as a function of the volume of fluid injected into the lens.
    In addition, several iterative computations can be performed in order to approximate as closely as possible to the actual shape of the flexible membrane and the state of the image retina's defocusing produced by a talotic. In one example, these complex computations were performed using a software system exemplary.
    The exemplary software system combined several different sets of software, each with a different function, in such a way that each piece of software feeds the computer with its results on the next system.
    As an example only, the following set was used in the - computations described in the exemplary embodiments in this document.
    The deformation of the fluid membrane was modeled under the COMSOL Multiphysics software, developed by COMSOL, Inc. of Burlington, MA.
    The COMSOL model output was exported to MATLAB software, produced 15º by The MathWorks, Inc. of Natick, MA, in order to obtain a better polynomial fit for this surface.
    A second polynomial order (quadratic) was used to calculate the best combination of ball and cylinder fit for this surface.
    This polynomial was then imported into the ZEMAX optical modeling software, produced by the ZEMAX Development Corporation of Bellevue, WA.
    The deformation of the fluid membrane was calculated as a function of its x, y coordinates in COMSOL for an elliptical fluid lens where the offset was 0.8. The long diameter was 35 mm, while the short diameter was 28 mm.
    The model was operated for one quadrant, taking advantage of quadruple symmetry.
    FIG. 4 illustrates an exemplary deformation gradient of a flexible membrane in a fluid lens in the frontal projection, as computed under the COMSOL software package according to these parameters.
    The contours shown in FIG. 4 demonstrate that the deformation was non-uniform across the membrane, reaching a maximum of 0.7 mm (700 microns) for a pressure of 2000
    Pascal.
    FIGS. 8a and 8b each represents a one-dimensional scan of the deformation shown in FIG. 4. FIG. 8a represents the deformation along the horizontal axis, and FIG. 8b represents the deformation along the vertical axis.
    The interlaced structure was made in a circular movement mode (extra thin) in three layers to include the curvature mode, generating 5439 elements in total.
    These data were exported in MATLAB for the best second order polynomial fit to be entered in ZEMAX.
    During the initial assessment of this computation scheme, “10 it was observed that a coarser structure size provided precision - adequate and fidelity to the surface generated by the finer structure size.
    In addition, it was observed that cross terms can be neglected in the best second order polynomial fit computed in MATLAB, so that the surface can be adequately represented as a simpler “conical with square terms in x and y, as shown in Eqs. 3 and 4.

The lowest boost power was assumed to be Ss 1.25D and the highest boost power was assumed to be 3.25D. Another assumption was that a maximum of 0.18D astigmatism can be allowed at the lowest power increase, while a maximum of 0.50D astigmatism was permissible at the highest power increase.
    In one embodiment, the non-uniform thickness of the flexible membrane is provided in order to modulate and change its deformation in response to fluid injection and the consequent increase in spherical augmentation power. A flexible membrane of varying thickness can be obtained in several ways, as described above. In one embodiment, a tape or pad is used to change the thickness on certain parts of the membrane surface. Such tapes or fillers can be cut from the same polymer film as that used to manufacture the flexible membrane, and then be attached to the flexible membrane. For example, tapes or fillers can be attached to the inner surface of the flexible membrane, in contact with the fluid (for example, oil), in order to minimize the visibility of tapes or fillers. The bonding of these tapes or fillers to the membrane can be performed using an adhesive. In one embodiment, the adhesive has a refractive index approximately equal to the fluid's refractive index. Alternatively, the tapes or fillers can be attached to the flexible membrane by means of laser welding or ultrasonic welding, or by other means, as should be known to those of skill in the art. One or more of such tapes or fillers can be used for this purpose. In one embodiment, tapes and fillers are not used to add thickness to the flexible membrane, so differences in thickness are an integral part of a single flexible membrane blade. Techniques for creating a flexible membrane of varying thickness include, for example, and without limitation, molding, compression molding, thermal formation, and laser ablation.
    FIGS. 5a, b and 6a, b illustrate the exemplary designs of tapes and “10 fillings modeled to deduce the ideal shape and contours in order to - modulate the rigidity of the membrane. FIGS. 5a and 5b illustrate the tapes 502, 504 applied along the x and y axes, respectively, of a flexible membrane 506. FIGS. 6a and 6b illustrate the fillers 602, 604 applied along the x and y axes, respectively, of a flexible membrane 606.
    Table 2 shows the results of the analysis of the exemplary designs shown in FIGS. 5a, b and 6a, b, comparing the application of a tape or filler (referred to in Table 2 as a piece of reinforcement) along x and y axes. In the exemplary model used in Table 2, the thickness of the reinforcement piece (for example, tape or filler) was the same as that - of the flexible membrane itself. That is, the thickness was doubled where the reinforcement was applied. The final analysis was performed under the ZEMAX software that was used to compute astigmatism over the entire range of spherical magnifying powers, as well as the size of the image point along the x and y axes. In this analysis, the decentralization was assumed to be 0.864, the - optics being 35 mm close to the long axis (x axis) and 30.25 mm close to the short axis (y axis). The lowest optical increase power is 1.25D and the highest optical increase power is 3.25D. The front surface of the rigid lens was provided with a toric correction such that the liquid astigmatism at the lowest magnifying power (1.25D) is 0.18D in all cases.
    The size of the point along the x axis is when focused to x; the point size along the y-axis is when focused to y.
    Table 2: Modeling of the reinforcement piece on the flexible membrane in an elliptical fluid lens reinforcement piece astigmatism - in | point size | spot size 3.25D along the x-axis, | along the y-axis, microns 0.73D microns filling along | 0.61D 13.2 of the x axis (Fig 5a) filling along | 1.02D 10.6 16.9 on the y axis (Fig 5b) tape along the x axis | 0.51D 9.7 12.5 S (Fig 4a) tape along the y-axis | 1.04D 10.4 17.0: (Fig 5b)
    Soon afterwards, the effect of the boost boost was examined as a decentral function.
    Table 3 shows the rate of astigmatism formation when the thickness of the reinforcement medium was increased in an exemplary model.
    In this exemplary analysis, the decentralization was assumed to be 0.864, with the long diameter being 35.0 mm.
    The lower and higher spherical increase powers were assumed to be 1.25D and 3.25D, respectively, with the adjustment range being 2.0D.
    It was also assumed that the front surface of the rigid optics was provided with toric correction along the appropriate axis, so that the liquid astigmatism at the lowest magnifying power is maintained at 0.18D.
    The astigmatism in the highest spherical power was calculated in ZEMAX, together with the dot size of the image.
    The base membrane was assumed to be unitary in thickness, so that a 1X thick reinforcement piece doubles the thickness of the membrane where it was applied.
    It is expected that the size of the image point will be correlated with the dispersion function of the retinal image point, a critical measure of the friability and clarity of the retinal image, and a measure of the image quality perceived by the user.
    In the example shown in Table 3, there was an improvement in image quality when the reinforcement thickness was increased in the fluid lens. Table 3: Alteration of astigmatism as a function of reinforcement thickness reinforcement piece | max. astigmatism spot size spot size in 3.25D along the x-axis, | along the y-axis, microns 0.73D Filling 1X 0.61D Filling 2X 0.37D Filling 3X | Uogao a go | 0.51D 0.35D] 0.17D ES It was observed in this example that the 3X reinforcement allowed the use of a non-circular optic for the 0.80 decentralization while remaining within the limits of the astigmatism specified for the spherical increase powers lower and higher (sph) (for example, 0.18 D at 1.25 sph and 0.50D at 3.25D sph). This level of descent is suitable for most - lens designs, as it provides a long shaft diameter of 40 mm for a short shaft diameter of 32 mm. Other deviations from the round shape (for example, a 0.7 off-center) can be achieved by increasing additional reinforcement, for example, by using a pad or tape that is 4X-6X thick.
    It should be noted that the analysis and results presented above referred to an exemplary paraxial situation assuming a pupil size of 4.0 mm. In other words, it was applicable in the center of the optics over a moderate field angle, less than 10 degrees. This analysis can be repeated at different angles of gaze for the entire optics. Such computation would still optimize the shape of the membrane, since it would be possible to prescribe the reinforcement schemes that provide the best correction for the entire optics, instead of providing the best correction in the optical center. In performing this global optimization, it can be recognized that the optical segments away from the center are not as important in determining overall visual satisfaction as the center of the optics, since most visualization tasks require direct stare with controlled eye movements that supplement head movements for most of the viewing experience close to comfortable. Other molded optics, such as rectangular or square shaped optics, can also be adapted for this method. The shape of the deformed membrane can be described, for example, as a collection of points such as a cloud of points, or a collection of “10 grooves used to adjust the points. In this case, the wavefront of the - rays transmitted through the liquid lens (including the deformed membrane) is computed, and an adaptive correction can be applied to the wavefront to maximize the image quality of the retina. Retinal image quality can be measured by one of several commonly used metrics of 15th image quality, such as the Strehl ratio or equivalent blur.
    Fluid lens insertion In an insertion-like design, the non-round shape of the fluid lens includes a circular or elliptical section centered on the user's pupil location. In such an embodiment, after placing on the glasses, the center of the pupil is placed in alignment with the center of the insertion. With a circular insert, the active region can be small depending on the lens frame, because the vertical diameter of the circular shape must fit within the vertical diameter of the frame. If the active region of the flexible membrane is too small, it may be unsuitable for a user since the movement of a user's eye may require a greater range of side-to-side up-down viewing. For example, an average user needs an active area width of about 30 to 35 mm for comfortable side-to-side eye movement. An elliptical insertion part takes into account such an active area width, even when the vertical dimension of the insertion is small compared to the active area width.
    FIGS. 7a, b illustrate an exemplary elliptical insert 702 in a fluid lens assembly 704. Insertion optics 702 is referred to herein as the active optical region.
    The active optical region is designed to inflate to release the desired boost power range.
    Astigmatism specifications at the low and high end of the power range apply only to the active region.
    The active region can be developed by contouring the thickness of the membrane being substantially thinner than in the surrounding optical region 7 10.
    For example, as shown in the exemplary elliptical insert 702: of FIG. 7b, it was observed that for an active region of 25 mm x 35 mm, a decentralization of 0.80 satisfies the optical specifications mentioned above over an increase power range of 1.50D, from 1.25D to 2, 75D.
    A membrane thickness ratio of 2X to 10X can be used to provide this segmentation of the total optical area.
    In one embodiment, the thickness ratio of the membrane is 3X to 7X.
    The smaller the thickness ratio, the more deflection is experienced by the outer zone.
    This leads to a higher level of astigmatism in the active zone.
    For such a design to be aesthetically acceptable, the edge of the active optical region can be smoothly blended, so that startling image distortions or noticeable image are avoided.
    It was found that the main causes of visual discomfort associated with this margin are: (1) discontinuity of the prismatic effect, (2) discontinuity of magnification, and (3) high localized astigmatism, caused by the discontinuity of the increasing power.
    These are also the main factors that contribute to the visibility of this margin, potentially leading to an aesthetically unacceptable result.
    These problems can be minimized by providing a transition zone.
    In one embodiment, the transition zone is approximately 1 to 5 mm wide.
    In an additional embodiment, the transition zone is approximately 2 to 3 mm wide.
    The width of the transition zone can be determined by the gradient in the increasing power within this zone, since the visual performance of this zone can be acceptable, for example, only by a gradient of increasing power of 0.50D / mm or less, leading to a maximum astigmatism value of 0.50D in this zone.
    In such an example, a 1.50D power range requires a 3.0 mm wide transition zone.
