Transitions Signature Flat Top 28 Available Exclusively from Younger

Transitions Signature Flat Top 28 Polycarbonate Composite lenses are now available exclusively from Younger Optics, according to an email from Younger.Its photochromic Trivex layer uses Chromea 7 technology. The lens, which has an 1.59 index like polycarbonate, reportedly has superb segment cosmetics.

Transitions Optical uses a proprietary process to make polycarbonate lenses photochromic. While this process works for a variety of lens geometries, it is not compatible with segmented, or flat-top lenses such as bifocals and trifocals. This has meant that traditionally, a polycarbonate FT28 lens has not been available with Transitions® technology. Until now. Younger Optics and Transitions Optical have developed a polycarbonate composite lens that incorporates a thin photochromic front surface bifocal layer made of Trivex — resulting in a lens delivering Transitions Signature performance in a product that is surfaced, polished, edged and dispensed just like a clear polycarbonate lens.
