摘要： A primer coating composition for bonding a functional laminate to a lens during cast-polymerization, including an acrylic polymer; a urethane acrylate oligomer; a reactive component capable of reacting with a lens-casting monomer for casting the cast-polymerized lens, a UV initiator or a thermal initiator, and a solvent. A method for cast-polymerizing a lens, including applying the primer coating composition to at least one external surface of a functional laminate; cutting and forming the functional laminate, placing the shaped functional laminate to which the primer coating is applied and a monomer for casting a lens in a casting cell so that the monomer contacts the primed surface of the functional laminate, and cast-polymerizing the monomer in the casting cell. An ophthalmic lens, including a cast-polymerized lens including at least one polymer, a functional laminate, and a primer coating obtained y curing the primer coating composition and deposited on at least one external surface of the functional laminate.

摘要： Disclosed is a method for manufacturing a three-dimensional article, including: a step of producing the article by an additive manufacturing technology, the article including at least two parts that face, at least partially, each other or that have edges facing, at least partially, each other; and a step of finishing of the article. According to the invention, the two parts are produced together with a temporary connection that links the two parts, and the method includes, after the step of finishing, a step of unlinking the temporary connection in order to separate the two parts.

摘要： A spectacle lens is disclosed that includes compound microlenses arranged in a pattern. A compound microlens includes an on-axis microlenslet and an off-axis sub-lenslet located on the on-axis microlenslet. The off-axis sub-lenslet has a different optical functionality than the on-axis microlenslet. By selecting the appropriate compound microlens design, the addition of microlenslets with sub-lenslets around the periphery of the main structure optimizes the spectacle lens for myopia prevention, vertigo prevention, or any other visual related condition.

摘要： The disclosure relates to a method of concealing a non-optically transparent component of an optical article. The method comprises—providing (S7) an optical article comprising: —an optical lens comprising an eyeball side facing an eye of a person when the optical article is worn by the person and an object side opposing the eyeball side, the optical lens comprising on the object side an eyewear shape section extending from an outer contour of the optical lens to an inner contour, and—a non-optically transparent component extending at least partly over the eyewear shape section, and—concealing (S8) the non-optically transparent component by covering at least part of the eyewear shape section of the optical lens using an opaque material.

摘要： This method for retrieving at least one optical parameter of an ophthalmic lens comprises: obtaining an image of a first and second patterns by using an image capture device located at a first position; from that image, obtaining a first set of data from at least a part of the first pattern that is seen through the lens by the image capture device and obtaining a second set of data from at least a part of the second pattern that is seen directly i.e. outside the lens by the image capture device; retrieving the at least one optical parameter by using the first and second sets of data and taking account of relative positions of the image capture device, the lens and the first and second patterns.

摘要： A finished lens with a predetermined shape, including one front face, one back face and a perimeter corresponding to the shape, including a prescription part on the lens that together with the front face fulfills prescription data of a wearer and a peripheral part on the lens, the prescription part being delimited by a thickness curve and the peripheral part extending from the thickness curve towards an outer edge of the lens, the thickness curve corresponding to a value of thickness less than or equal to a predetermined thickness requirement.

摘要： A method for determining an optical lens adapted for a wearer and optimized for at least a given optical criterion having a target value around a specific gaze direction. The method includes determining an intermediate optical lens by optimizing, using an optimization function, an initial optical lens so that the difference between the value of the at least given optical criterion of the intermediate optical lens and the target value of gaze directions around a specific gaze direction is smaller than or equal to a threshold value, and determining the optical lens by optimizing the intermediate optical lens so as to obtain the largest zone of gaze directions around the specific gaze direction for which the difference between the value of the at least given optical criterion and the target value around the specific gaze direction is smaller than or equal to the threshold value.

摘要： A device and a method for determining a change in the visual comfort of a user, the device including at least one light source for stimulating at least one eye of the user, a sensing circuit facing at least one eye area of the user when the device is worn by the user, the sensing circuit being configured to remotely acquire at least one signal representative of at least one characteristic of said at least one eye area, and a controller configured to determine a change in the visual comfort of the user depending on a variation of said at least one signal acquired by the sensing circuitry.

摘要： 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.
