Segmented Multifocal Lenses:
FT28 Bifocal • FT35 Bifocal • 7 x 28 Trifocal
Transitions® Signature® VII polycarbonate composite technology is now available in FT28 bifocal, FT35 bifocal, and 7 x 28 trifocal lenses.
This means even more multifocal wearers can now enjoy the unsurpassed photochromic performance of Transitions® Signature® VII.
Transitions Optical, Inc. 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 lead to Younger Optics and Transitions Optical developing a polycarbonate composite lens that incorporates a thin photochromic front surface bifocal layer made of Trivex® — resulting in a lens delivering Transitions Signature VII performance in a product that is surfaced, polished, edged and dispensed just like a clear polycarbonate lens.
Now available in gray and brown from all laboratories.
