Introducing the first safety glasses with transition lenses...

Automatically lightens and darkens with changing light conditions

Innovative safety glasses take the hassle out of having to change your eyewear in different light conditions. The lenses in these glasses do all the changing for you automatically. The lenses are “UV reactive” and respond to the amount of ultraviolet (UV) light received. Lenses change from clear to dark in eight seconds and from dark to clear in 35 seconds. Glasses feature a durable frame with spring hinged temples for a universal fit and a soft, adjustable nose bridge for all-day comfort. Lenses have a scratch resistant coating and block out 99.9% of harmful UV rays. Meets ANSI Z78.1-2003. Imported. NOTE: Outdoor temperatures may affect transition time.
