ROCHESTER, N.Y.—Rochester Optical is launching PolyShade85, a polycarbonate finished single vision category 3 sun lens with tint embedded in the substrate. PolyShade85 lenses allow an average of 15 percent visible light transmission and block up to 90 percent high-energy visible blue light, according to Rochester Optical. The company claims they are the darkest finished single vision polycarbonate sun lenses on the market.

Rochester Optical recommends PolyShade85 for patients of all ages, especially children looking to wear sun lenses for outdoor and sport applications without compromising eye protection. The lenses also provide a solution to optical retailers who want to offer one-hour or same-day prescription sunglasses.

Rochester noted that PolyShades85 lenses can be used in drill mounts, and eliminate the problem seen with tinted clear poly lenses of white edges appearing at the lens circumference. The tintable hard coat allows for further flexibility to fine tune desired transmission rate by enhancing darkness.

PolyShade85 finished single vision stock lenses are available in -6.0D to +4.0D sphere out to -2.0D cylinder; single vision semi-finished blanks are available in .50 – 8 base curves, which offer additional power range possibilities and digital progressive designs.
