TECHNOLOGY: Spectacle Lenses PPG, Thai Optical Group and Global Optics Announce NA Availability of Tribrid Lenses By Andrew Karp Monday, October 17, 2016 12:00 AM PITTSBURGH—PPG, Thai Optical Group and Global Optics are introducing Tribrid lenses in North America. The high-performance high-index lenses are available in semi-finished single vision clear lenses and are compatible with digital free-form processing and anti-reflective coatings. Tribrid lens material was developed by PPG using an advanced hybrid material approach incorporating chemistry for Trivex lens material with traditional high-index lens material chemistry. The result is a high-index lens that offers the combination of vision comfort, protection and performance with enhanced thinness. Tribrid has several features: optical clarity with an Abbe number of 41; lightweight comfort with density of 1.23 grams per cubic centimeter; thinness with refractive index of 1.60; impact resistance with the ability to withstand more than 160 times the energy of the U.S. Food and Drug Administration drop ball test; and 100 percent protection from ultraviolet (UV) radiation. With the launch of Tribrid lenses in the region, Global Optics also announced that any optical laboratory can now apply to become a Global Optics associate member. akarp@jobson.com
