UVEX

If you're bursting in and out of shadowy forests, the slow reaction time of photochromic glasses just can't keep up. That's where Uvex's Variotronic glasses come in, which change tint in just a tenth of a second. We recently tried a pair out.

A new "variotronic" double lens helmet visor can be electronically switched from light to dark by pressing a button and it can even be switched to automatic mode, where the lens is controlled directly by an integrated photo cell.
