Tonic Sunglasses, High Contrast Copper Bronze Photochromic?
Submitted by kfish on Tue, 2012-09-25 10:29
Has anyone got a pair of these? Is the colour transition visually obvious? I can't tell if they are changing colour and I'm worried I got a polycarbonate pair instead of a glass photochromic...
Is there any other way I can tell if they are glass photochromic lens?
