Introducing the first safety glasses with transition lenses...

Transition safety glasses automatically lighten and darken with changing light conditions

Innovative transition 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 in transition safety glasses 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. Transition safety 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 Z87.1-2003. Imported. NOTE: Outdoor temperatures may affect transition time.
