PHOTOCHROMIC
LENSES
High wearing comfort thanks to
self-tinting lenses
Wetzlich uses transition technology for photochromic lenses. In their basic state,
glasses with only 5% tint cannot be distinguished from clear glasses. When exposed to
sunlight, the lenses tint to the equivalent of sunglasses (approx. 80% tint) within 30
seconds.
