AVON, France--Corning Ophthalmic is expanding and upgrading its SunSensors line of plastic photochromic lenses with the addition of SunSensors HPC, a new high performance photochromic coating. The coating, which Corning developed in conjunction with Tokuyama, can be used on a broad range of materials currently used in the market, such as polycarbonate, 1.60 index and 1.67 index plastic lenses.

 
Corning’s new SunSensors HPC coating is available on Polycore’s polycarbonate semi-finished single-vision and progressive lens designs in both gray and brown.
According to Corning, the technology offers high clarity and blocks 100 percent of harmful UVA and UVB radiation. It achieves one of the highest levels of performance on the market for darkening and fading speed, changing from a gray dark state transmission of 11 percent to 65 percent transmission after only five minutes of fading time.

“Corning’s lens manufacturing partners desire a SunSensors photochromic product that can be applied to different materials and lens types,” said John Massey, product line manager, plastic photochromics, Corning Ophthalmic.

“With the development of this solution, we meet their needs and provide them with the quality and service they expect from Corning.” Polycore is the first lens manufacturer to offer SunSensors HPC lenses. Beginning in July, the company introduced the coating on its polycarbonate semi-finished single-vision and progressive lens designs.

“After months of collaboration with Corning to develop a high-performance SunSensors photochromic, polycarbonate lens, Polycore Optical is proud to be the pioneer in marketing this premium photochromic lens,” according to Hashim Osman, sales and marketing director, Polycore Optical.
