PHOTOCHROMIC TECHNOLOGY
Photochromic lenses automatically adjust to light intensity.
The lens changes tint in about 30 seconds (45 seconds to clear).
The brightness feeling varies little, even if the outside brightness changes.
For example, when cycling, the change in tint is hardly noticeable.
The tint transition is smooth so that the eye can adjust at the same time.
A cold temperature will activate (shade) the lens more rapidly.
