  • Patent number: 12115621
    Abstract: Disclosed is a lamination machine including: a film support for receiving a functional film to be laminated; an article support configured to receive and position the optical article in a predetermined orientation; and an actuating member configured to move the film support and the article support toward each other for laminating at a predetermined pressure the functional film received in the film support onto the optical article received within the article support. The article support is a blocker support configured to receive a surfacing blocker onto which the optical article is to be disposed for lamination, the article support being further configured to transmit laminating forces induced by the predetermined pressure to the lamination machine during a lamination operation.

  • Patent number: 10859466
    Abstract: Conventionally, eyewear is rated in terms of its absorption coefficient (sometimes called the optical density (OD)) or the protection that it provides from ultraviolet (UV) radiation, which can damage the eye at high enough power levels. Infrared (IR) radiation can also damage the eye, but IR damage tends to occur at a much slower rate than UV-induced damage. Rating eyewear in terms of protection from IR radiation and/or in terms of a maximum safe exposure duration (SED) to IR radiation improves consumers' ability to protect themselves from IR radiation. In addition, eyewear rated for more IR protection or longer SED may still provide excellent vision thanks to coatings that reflect or absorb IR light and transmit visible light.

  • Publication number: 20190154881
    Abstract: Ultraviolet (UV) radiation can harm the eye. Fortunately, a spectacle lens can be coated with a UV anti-reflection (AR) coating to reduce the amount of UV radiation incident on the eye. If the AR coating is on the back side of the lens (the convex surface closest to the eye), the AR coating will reduce the amount of UV light that is transmitted through the lens to the eye. It will also reduce the amount of UV light that is reflected off the back side of the lens toward the eye. The AR coating may include five or more alternating layers of silicon nitride and silicon dioxide or other suitable dielectric materials. It can be sputtered onto the back side of the lens as part of an on-block manufacturing (OBM) process while the ophthalmic lens blank is still attached to the block, before the ophthalmic lens blank is removed and edged.
