PHOTOCHROMATIC TECHNOLOGY

Photochromic lenses automatically adjust to light intensity.



Lenses darken in approximately 30 seconds (takes 45 seconds to lighten).

The perceived brightness does not change much even when the outside brightness level changes.

For example, when cycling, the change in tint is almost imperceptible.

The tint adjusts gradually, and the eye adjusts to it.

A cold temperature will activate (tint) the glass more easily and the tint transitions will be longer.
