Abstract: The invention relates to a method for manufacturing an ophthalmic lens having at least one optical function, comprising the step of providing a starting optical system of the lens, having a basic optical function and the step of additively manufacturing an additional optical element of the lens, by deposition of multiple predetermined bulking components made of at least one material having a predetermined refractive index, directly onto the front surface and/or the rear surface of the starting optical system; wherein the additive manufacturing step comprises the step of determining a manufacturing guideline for the additional optical element on the basis of the characteristics of said at least one optical function to be provided to the lens, the characteristics of said at least one basic optical function, the geometric characteristics of the starting optical system, and the predetermined refractive index of the material.

Abstract: A method is implemented by a computer for modifying a non-dioptric parameter of an optical system including a first and a second surface. The method includes a modifying step during which the first surface and second surface are modified so as to obtain a modified optical system such that the dioptric function of the modified optical system is substantially the same as the dioptric function of the optical system.

Abstract: The present disclosure relates to a method for providing a user with a contextualized evaluation of a fit of frames of eyeglasses to their face. In particular, the present disclosure relates to a method, comprising receiving user data describing features of the face of the user, receiving equipment data describing features of the eyeglass frame, generating, according to a first model, values for a set of specific criteria describing compatibility between the face of the user and the eyeglass frame, the first model trained to associate user data and equipment data with values of specific criteria, generating, according to a second model, a value of a global criterion based on the generated values for the set of specific criteria, the second model trained to associate the values of specific criteria with values of global criteria, determining a message characterizing the eyeglass frame with respect to the face of the user.

Abstract: Disclosed is a method for determining an updated visual correction need for designing a new vision correcting device of an individual already having a previous vision correcting device previously designed to correct his/her vision, wherein, in a first step, a previous level of correction of the previous vision correcting device is acquired, in a second step, a current vision acuity parameter of the individual wearing the previous vision correcting device is assessed, and, in a third step, the updated visual correction need is determined based on the previous level of correction of the previous vision correcting device acquired in the first step and on the current vision acuity parameter assessed in the second step. A complementary visual correction need can also be determined.

Abstract: A method for checking the compliance of a checked optical characteristic of a checked ophthalmic lens (30) relative to an expected optical characteristic, from a non-deformed pattern (40) and a deformed pattern (20) each having a non-uniform contrast, the method includes the steps of: a) determining (A) an image pattern (50), which is the image of the deformed pattern through the checked ophthalmic lens, in predefined optical conditions, b) combining (B) the image pattern with the non-deformed pattern to form a test pattern (60), c) comparing (C) the test pattern with at least one reference pattern (70), and d) deducing (D) the compliance of the checked optical characteristic with the expected optical characteristic on the basis of the preceding comparison. A device for implementing such a checking method is also described.

Abstract: The present disclosure relates to a method for expanding an image database for evaluation of eyewear compatibility. In particular, the present disclosure relates to a method, comprising receiving a user image, receiving a frame image, processing the received frame image by setting, as transparent, pixels of the received frame image except for an anterior face of the frame, defining, within the processed frame image, a left boundary and a right boundary of the anterior face of the frame, the left boundary and the right boundary corresponding to the left eye and the right eye, respectively, receiving a filter image, processing the received filter image by setting, as transparent, pixels in the received filter image outside the frame based on the left boundary and the right boundary, merging the processed frame image and the processed filter image, and overlaying the merged image onto the received user image.
