Item specifics
Item description from the seller
An important note about photometric lenses:
Because they react to UV light and not to visible light, there are circulations under which the darkening will not occur Frist example, is in your car Because the windshield blocks out most UV light, photochromic lenses will not be dark Second, is indoors test with ordinal lighting (Because the lighting used in daily lighting does not contain ultraviolet light), photochromic lenses will not be dark
So the ways to activate photochromism is:
Exposed to UV rays, as in direct sunlight OR Use ultraviolet light lamp (not ordinal lighting lamp). This is the way to activate the photometric function of the product
