Patent number: 10859466Abstract: 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.Type: GrantFiled: February 16, 2017Date of Patent: December 8, 2020Assignee: SHAMIR OPTICAL INDUSTRY LTD.Inventors: Zohar Katzman, Gilad Markman, Devora Nuriel

Publication number: 20190154881Abstract: 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.Type: ApplicationFiled: November 15, 2018Publication date: May 23, 2019Inventors: Zohar KATZMAN, Benny NOV
