PHOTOCHROMIC

Automatically change the lens color.

Thanks to our lens brightness control technology, SWANS products can automatically adjust the lens brightness to compensate for all weather conditions,
from snowy, rainy, or cloudy to sunny, reacting to the amount of ultraviolet rays.
The lens color darkens when the amount of ultraviolet light increases and lightens when the amount of ultraviolet light drops off.
SWANS’ innovative photochromic technology features quicker color changes and higher reactiveness
to small changes in the amount of ultraviolet light than other general photochromic lenses on the market.
