Vision USA, Cherry Hill, NJ, a Dentrex company, offers the new Sport Expo Safety SUN/Glasses, featuring photo chromic lenses that change automatically from clear to smoked (three shades) when venturing into bright sunlight.

As the sun goes down, so does the tint.  Polycarbonate lenses bock 100% of harmful UVA and UVB rays, the company says. The glasses meet ANSI Z87.1+ requirements.
