The disclosure relates to a process for manufacturing an optical article, including: providing an optical article manufactured by additive manufacturing, the optical article having a first main surface and a second main surface; providing at least one added value film including at least one added value layer; and attaching the at least one added value layer onto at least one of the two main surfaces of the optical article by laminating the at least one added value film onto the at least one main surface.

Process for manufacturing an optical article with an added value film

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 &#x2212;1.00 Diopters and &#x2212;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.

System and method for demonstrating an optical disorder

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.

Frame optimization system and method

The invention concerns a method of manufacturing an ophthalmic lens, comprising the steps of providing, mounting and blocking a substrate () on a machining support unit (), surfacing an upper face () of said substrate, edging a peripheral edge () of said substrate, wherein said machining support unit comprises a surfacing member () and an edging member () which are separable, said surfacing member having a cavity () in which said edging member is located during said step of surfacing, said surfacing and edging members being configured so that said substrate is mounted and blocked on said machining support unit in a first predetermined position for the surfacing and the edging and, between said steps of surfacing and edging, the method comprises the step of withdrawing said surfacing member from said machining support unit by retaining said substrate on said edging member.

Disclosed is eyeglasses equipment () including a frame (), and at least one ophthalmic lens () mounted into the frame. The equipment includes a colored interface () that is placed between the frame and the lens.

Eyeglasses equipment including a joint and method for manufacturing such an eyeglasses equipment

A method of manufacturing an ophthalmic lens, includes the steps of providing, mounting and blocking a substrate () on a machining support unit (), surfacing an upper face () of the substrate, edging a peripheral edge () of the substrate, wherein the machining support unit includes a surfacing member () and an edging member () which are separable, the surfacing member having a cavity () in which the edging member is located during the step of surfacing, the surfacing and edging members being configured so that the substrate is mounted and blocked on the machining support unit in a first predetermined position for the surfacing and the edging and, between the steps of surfacing and edging, the method further includes the step of withdrawing the surfacing member from the machining support unit by retaining the substrate on the edging member.

Systems and methods for providing identification factors for an individual wearer. Some or all of the identification factors when within a predetermined value provide a prescription and corrective ophthalmic lenses for a selected individual wearer, the corrective ophthalmic lens having at least one correction that is to the nearest 0.20 diopter, or is in a range between about the nearest 0.01 diopter and about the nearest 0.20 diopter. The prescription and corrective ophthalmic lenses are obtained by at least first analysis performed with a first instrument, a second analysis performed with a second instrument, and a third analysis performed with a third instrument, in which each instrument is different, and each analysis is different.

Systems and methods for measuring refractive error and ophthalmic lenses provided therefrom

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.

Eyeglass rating with respect to protection against UV hazard

A method that includes providing a cavity defined by at least a portion of a mold and a closure member attached to the portion of the mold, the portion of the mold being oriented vertically and having a top and a bottom, and a sealing material being positioned near the bottom and attached to the closure member; puncturing the sealing material and the closure member with an instrument near the bottom, the puncturing creating an opening in the sealing material; and introducing a polymerizable composition into the cavity through the instrument. A method useful in testing sealing materials. Other methods are also disclosed.
