Features:

Photochromic lenses have UV400 function and will change color under direct sunlight. Discoloration occurs in about 1 minute in winter and about 40 seconds in summer. Speed depends on sunlight and UV intensity! (If the UV intensity and temperature are low, the color change rate will be slower.) The color change rate is related to the UV intensity and temperature.
