    PROCEDURE FOR THE MANUFACTURE OF LENSES AND MOUNTS, PERSONALIZED DESIGN AND REMOTE BEZELING OF OPHTHALMIC LENSES. AND OPTICAL EQUIPMENT FOR MORPHOLOGICAL MEASUREMENT TO CARRY OUT SAID
    PROCESS
    D E S C R I P C I O N
    OBJECT OF THE INVENTION
    The invention, as stated in the present specification, refers to a process for the manufacture of lenses and frames, of custom design and remote beveling of ophthalmic lenses, and an optical morphological measurement equipment for carrying out said procedure, contributing, to the function to which it is intended, advantages and characteristics, which will be described in detail below, which represent a remarkable novelty in the current state of the art.
    More specifically, the object of the invention focuses on a method and application equipment in the optical sector which, essentially comprising a 3D scanner, camera and various specific software, has the capacity to obtain a patient's three-dimensional facial morphology / client with millimeter measurements for the manufacture of customized ophthalmic lenses, as well as to create the frames for said lenses of the size and shape chosen by the patient, after designing them on demand and virtually testing them on the three-dimensional image obtained, automatically generating and corresponding file compatible with 3D printers.
    The procedure and the equipment also allows to obtain, not only the glasses that the system personalizes, but of any frame provided by the client, the exact form of this and, by means of a specific software, a file compatible with the bevelling machines of the market, which will contain all the parameters that are needed to be able to cut any glass to the shape of the frame, a process called beveling. This chamfering can be done in the same store or remotely.
    FIELD OF APPLICATION OF THE INVENTION
    The field of application of the present invention is framed within the field of optics,
    2

    focusing on the field of industry dedicated to the manufacture of equipment, devices and morphological measurement devices for the manufacture of lenses, as well as those for the manufacture of frames.
    BACKGROUND OF THE INVENTION
    As it is known, in the manufacture and beveling of the customized ophthalmic lenses, fundamentally, and in all ophthalmic lenses in general, it is decisive to take measurements of the user's facial morphology, which are unique for each person and eyeglass chosen. Specifically, the measures taken are: nasopupillary distance; pantoscopic angle; Galbe angle; vertex distance; angle of curvature; reading distance and shape of the frame and position of the pupil.
    Currently there are several equipment for taking measurements for the manufacture of prescription lenses.
    The operation of this equipment is by taking pictures of the patient with glasses with predetermined markers (five normally). The 2D images obtained are combined with the markers of the glasses, which serve as reference, and the necessary measures for the manufacture of the corresponding lens are estimated.
    The problem is that these teams make an estimation of the necessary values, resulting in numerous errors, since they depend, to a large extent, on the position at that time of the head of the client / patient. In fact, the manufacturers of such equipment themselves point out that adjustment errors can cause a loss of up to 40% in lens performance.
    As an example of these common mistakes, we attach below three tests performed on the same day to the same subject. The tests are identified with codes 0052, 0053 and 0055 and despite being performed on the same individual, very different results are obtained:
     PANTOSCOPIC ANGLE GALBE ANGLE INTERPUPILAR DISTANCE EYE RIGHT / EYE LEFT HEIGHT EYE RIGHT / EYE LEFT D. VERTICE EYE RIGHT / EYE LEFT
     0052  13.5 ° 5.9 ° 32.6 / 30.80 22.5 / 25.4 16.7 / 16.5

     0053  10 ° 5.8 ° 32.7 / 30.8 19.8 / 21.8 16.7 / 16.8
     0055  -1.2 ° 2.4 ° 33.1 / 30.5 14.4 / 16.6 14.4 / 13.5
    It can be seen that the results are very different depending on the inclination or position of the patient's / client's eyes when taking the corresponding photographs.
    In these tests the variations in the position of the patient / client are not very marked, but there are cases in which the position of the patient / client during the data collection, either because of the position that has to be adopted (must be standing, adjusting to some marks on the floor and on the screen) or by the stress of being tested, it has nothing to do with the usual position of the patient / client in their daily lives.
    This means that the measures taken adjust little to reality and therefore the lenses manufactured based on these measures are not optimal for the patient / client, which will find it difficult to adapt to them. This adaptation problem is further accentuated in the case of progressive lenses.
    The objective of the present invention is, therefore, to develop an improved measuring equipment for obtaining morphological measurements that allows adjusting them much more loyal to reality and, consequently, achieving a much more adjusted lens fabrication. the specific needs of each patient.
    On the other hand, and as a reference to the current state of the art, it should be noted that, although it has been noted in the market and ophthalmological measurement equipment is known, at least by the applicant, the existence of none that is known is unknown. present the technical, structural and constitutive characteristics similar to those presented here, as claimed.
    EXPLANATION OF THE INVENTION
    Thus, the procedure for the manufacture of lenses and frames, of custom design and remote beveling of ophthalmic lenses, and the morphological measurement optical equipment to carry out said procedure, which the invention proposes are configured as a novelty within its field of application, since, according to its implementation and in a restrictive way, the previously stated objectives are satisfactorily achieved, the details being

    characterizers that make it possible and that distinguish it conveniently set out in the final claims that accompany this description.
    Specifically, what the invention proposes, as noted above, is a team that, essentially comprising a 3D scanner, camera and specific software, allows to obtain an image of the facial morphology in three dimensions of a patient / client with millimeter measurements that are used both for manufacturing and for beveling and subsequent mounting of ophthalmic lenses of any type.
    In addition, such equipment also allows its use to manufacture and create custom glasses frames with 3D printers, since it allows to create a frame of the size and shape chosen by the client.
    To do this, once the morphological data of the face is obtained by scanning the bust of the client and having added the corresponding texture with a photograph, you can virtually test on a 3d mesh generated models of glasses that the client can digitally vary on his face scanned In the end, the client will be able to choose a certain size and shape of mount, which he has virtually tested on his scanned image, and by means of the specific software, a data file compatible with 3D printers is generated that allows his impression in said type of devices for Obtain a fully customized and customized frame, adjusted to each client.
    To do this, once the morphological data of the face is obtained by scanning the bust of the client and having added the corresponding texture with a photograph, you can virtually test on said 3D image models of glasses that the client can vary, in its shape and size, digitally on your scanned face. In the end, the client will be able to choose a certain size and shape of mount, which he has virtually tested on his scanned image, and by means of the specific software, a data file compatible with 3D printers is generated that allows his impression in said type of devices for Obtain a fully customized and customized frame, adjusted to each client.
    Likewise, once the morphological data of the face is obtained, the client will be able to obtain all the necessary measures for the manufacture of the personalized crystals to the client and beveled all the ophthalmic lenses.

    In addition, the team can also take the measurements of a spectacle provided by the client and obtain from it all the necessary parameters for its remote beveling.
    For all this, and specifically, the team of the invention is made up of the following main elements:
    - A fixed structure to which the rest of the elements of the equipment are coupled, counting, at least, with an elevated support to place the 3D scanner and the camera at the height of the client's head. This structure, therefore, provides the fastening of the scanning system providing stability. Preferably, it constitutes a structural assembly mounted from the ground or from the ceiling.
    - A mobile structure where the 3D scanner is attached, which, at least, has automatic or manual actuation means to move said scanner vertically and place it at the convenient height, although, optionally, it will also have mobility in the horizontal plane to revolve around the client's head or bust. Preferably, this mobile structure is a circular body that rises and descends and rotates around itself surrounding the head of the patient / client, and whose inner face is suitable so that they do not affect the data collection of the scanner, nor the exterior light , nor possible reflections, so that the lighting is adequate.
    - 3D scanner, incorporated, as noted, in the mobile structure, constituting the electronic device that will take the actual measurements on the patient's head or bust, including those on the face, generating a three-dimensional image of it with millimeter precision .
    - A camera, preferably, also coupled to the mobile structure of the 3D scanner, although not necessarily. The purpose of the photographic camera is to provide texture to the 3D image obtained through the scanner.
    - A CPU (of the English Central Processing Unit) with a specific scanning software, which achieves an improved 3D virtual model obtained simply with the scanner as it allows to add, in an easy way, the texture of objects and faces from the taking of a photograph obtained with the camera, improving the image of the bust obtained from the scanner with easy steps that do not require

    expert manipulation.
    The CPU also incorporates specific software for data collection, visualization and modification of glasses, thanks to which, based on the data obtained from the scan, a graphic interface is generated for the adjustment of the glasses that allows the user to adjust The size to your liking and comfort. This interface also allows measuring the pantoscopic angle, Galbe angle, interpupillary distances and the distance to the optical center.
    Finally, the software is capable of generating, if desired, a file of the mount model chosen or designed in the graphic interface, in a compatible format for obtaining it by means of a 3D printer.
    The CPU also has other specific software to obtain, from any mount, a 3D image of it, take the necessary measurements and generate a file compatible with the bevelling machines on the market, which will contain all the necessary parameters to be able to perform the bevelling of any type of ophthalmic lens, that is, the trimming of any glass to the shape of the frame.
    - A screen connected to the CPU to visualize the 3D generated image and the graphic interface, which can be of the touch screen type and / or be linked to a keyboard for the interaction with the software.
    With all this, the operation of the equipment is as follows:
    Either starting from the floor or from the ceiling, the support structure of the scanner and the camera will be placed at the height of the bust of the patient / client standing. When the structure is positioned and fixed at the correct height, the corresponding photos will be taken by the camera and the scanner will collect your data to elaborate your images of the bust of the client / patient through the mobile structure that is automatically or automatically operated manual.
    The inner face of the mobile structure, as already mentioned, is designed so that they do not affect the data collection of the scanner or the exterior light, or possible reflections, as well as so that the lighting is adequate, so preferably incorporates lighting.

    Once the mechanical imaging process is finished, the structure will return to its initial position.
    With the data obtained from the scanner and the camera and through the described specific software, an improved 3D image of the client / patient will be obtained. And with the second software developed, all the measures for the manufacture of the specific crystals of each client will be obtained, and frames adapted to said client can be varied or designed and will serve as a tester with real image of existing frames.
    Therefore, the main stages of the recommended procedure for the manufacture of lenses and frames, of custom design and remote beveling of ophthalmic lenses proposed in the present invention comprise at least the following stages:
    - obtaining morphological data of the patient / client with millimeter measurements through 3D scanning of the bust,
    - adding texture of objects and faces to photographs of the patient obtained with the camera,
    - generation of virtual 3D mount model on the photographic image,
    - data collection, through graphic interface measuring the pantoscopic angle, Galbe angle, interpupillary distances and the distance to the optical center to manufacture the lenses
    - Generated file compatible with beveling machine, containing all the parameters to bevel of any type of ophthalmic lens, suitable for the shape of the frame.
    In addition, when what is going to be manufactured is a new frame, after the generation of a virtual 3D model of the frame on the photographic image, it comprises stages of:
    - visualization and modification of frames, size adjustment and design of the virtual model frames, and once chosen,
    - generated from the data file of the chosen frame in compatible format for its manufacture by 3D printer.
    And, when the frame is an existing frame provided by the patient / client for the beveling of lenses suitable for it, in the generation stage of the virtual 3D frame model, the procedure comprises steps of:

    - measurement data of said mount
    - and, subsequently, the file compatible with beveling machine is generated, containing all the parameters to bevel of any type of ophthalmic lens, suitable for the shape of the frame.
    The described procedure and optical morphological measurement equipment for the manufacture of lenses and frames, of custom design and remote beveling of ophthalmic lenses, represents, therefore, an innovation of structural and constitutive characteristics unknown until now, reasons that together with its practical utility , provide it with sufficient grounds to obtain the privilege of exclusivity that is requested.
