RANCHO CORDOVA, Calif.—VSP Optics Group is launching a fast-acting, high performance photochromic lens, SunSync Plus, which changes from dark to clear three times faster than the current industry leader, according to VSP. The lenses have luminous transmittance of 88.5 percent with an AR coating applied, on par with the clearest photochromic lenses available; luminous transmittance is 11 percent when fully activated, making them sunglass dark.

SunSync Plus lenses darken quickly to a “true gray” color when activated by sunlight, and have no residual color. In an un-activated state, their color is similar to clear lenses in the same material, according to VSP. Consistent performance, regardless of thickness or power, is assured by a unique formulation of photochromic molecules applied in a thin layer near the front surface of the lenses.

SunSync Plus lenses block 100 percent of UV radiation, selectively filter blue light, and resist scratches and smudging. They are backed by a one-year, 100 percent satisfaction guarantee for VSP Members. They are available exclusively with Unity Via progressive lenses as of July 12, 2017.

“SunSync Plus and Unity Via are two of the most innovative advancements in lens technology, so it’s only fitting that this ultra-fast photochromic be paired with a progressive lens that’s easy to fit and offers effortless vision to the patient,” said Randy Dannewitz, vice president of strategic development for VSP Optics Group.

SunSync Plus are available in gray in 1.50 plastic, 1.59 polycarbonate and 1.67 high index.
