  • Patent number: 11810468
    Abstract: A method for demonstrating an optical disorder includes providing two ophthalmic lenses in a first position relative to each other. Each lens includes a first vision zone and a second vision zone. The first vision zone includes a distance vision zone having a distance vision reference point and a power of between about ?1.00 Diopters and ?4.00 Diopters. The second vision zone includes a near vision zone having a near vision reference point and a power of between about +1.00 Diopters and about +4.00 Diopters. Each lens includes an Add power of between +2.00 Diopters and +3.25 Diopters; the ophthalmic lenses are repositioned to a second position relative to each other, so the distance vision zone of each lens is viewable by a wearer through the near vision zone and the near vision zone of each lens is viewable by a wearer through the distance vision zone.

  • Publication number: 20220031158
    Abstract: Disclosed is a method for determining at least one geometrico-morphological parameter of a subject for determining a vision correction equipment, wherein the following steps are performed: a) determining the height of one of the eyes of the subject (P) relative to a reference horizontal surface; b) placing a visual target in front of the head (HP) of the subject (P) at a predetermined position, this predetermined position being determined taking into account the height of one of the eyes of the subject relative to the reference horizontal surface, determined in step a); c) while the subject gazes at the visual target placed at the predetermined position in step b), capturing an image of the head (HP) of the subject (P) with an image capture apparatus (50); and d) deducing from the image captured in step c) the at least one geometrico-morphological parameter.

  • Patent number: 11189366
    Abstract: The disclosed embodiments include a system that has a processor for executing computer-executable instructions and a computer-readable storage media for storing the computer-executable instructions. These instructions, when executed by the processor, enable the system to receive prescription data of a patient for corrective lenses and image data associated with the face of the patient. The system is configured to determine lens attributes for the patient based upon the prescription data and also determine facial attributes of the patient from the image data. Based on the lens attributes and the facial attributes of the patient, the system determines at least one frame recommendation for the patient.

  • Publication number: 20160320302
    Abstract: An index value is calculated for rating an eyeglass with respect to protection against UV hazard. The index value is based on an integrated UV transmission value through the eyeglass and an integrated UV reflection value related to a back face of the eyeglass. Thus, the index value takes into account actual wearing conditions where UV eye exposure is due either to transmission through the eyeglass or reflection on the eyeglass back face. Respective index values obtained for a set of eyeglasses allow easy sorting of the eyeglasses with respect to UV protection efficiency.

  • Publication number: 20160167299
    Abstract: Presented herein is a method of manufacturing a three-dimensional ophthalmic lens using additive manufacturing. The method includes constituting voxels of one or more compositions, wherein at least one of the compositions includes one or more pre-polymers or polymers, and inducing connectivity between the voxels, thereby creating one or more incremental elements, repeating the constitution steps, and performing a final post-treatment. Also presented herein is an ophthalmic lens obtained by this method. The lens has good homogeneity and optical clarity, reduced shrinkage, and improved geometric accuracy and thermo-mechanical properties.
