Parameters

Advantages of Q-Active

Outstanding Color Performance • Fast color of changing, from transparent to dark and vice versa. • Perfectly transparent indoors and at night, adapting spontaneously to varying light conditions. • Very dark color after change, the deepest color can be up to 75~85%. • Excellent color consistency before and after change. UV Protection • Perfect blockage of harmful solar rays and 100% UVA & UVB. Durability of Color Change • Photochromic molecules are evenly distributed in lens material and keep active year by year, which ensure durable and consistent color change.
