The molecular structure of the silver halide molecules embedded in the lenses changes when exposed to UV rays. The lens tint therefore varies automatically in response to light intensity within a 10-second period.

The D-Art Biochromik glasses' nylon frame is impact resistant, very lightweight and flexible in a wide range of temperatures. The vented frame helps prevent fogging, and the photosensitive Biochromik lenses adapt to the intensity of the UV rays, automatically adjusting to the light within a 10-second period.
