Copyright © 2012 Survival Skills & Kevin Williams Contrast-enhancing yellow tint  Used by skiers for years, and more recently by racers, a yellow "contrast enhancing" tint is extremely effective in poor light conditions and rain, when the world appears flat and two dimensional. Unlike yellow visors, these CE-approved impact-resistant, anti- scratch wrap-around glasses are legal for use on the road. Smoke tint   Not ultra-dark, but they take a significant amount of the glare out of the light of a sunny day, particularly when the sun is low and near the horizon. Once again, they are built to the same to the CE safety eye-wear standard, and are lightweight and comfortable under a helmet. Protective carrycase Just like anti-scratch visors, anti-scratch glasses are scratch RESISTANT, not scratch proof! Treat them with the same level of care and clean them as carefully as you would a visor. To protect your glasses off the bike, here's a soft protective zip case that can be slipped in a pocket or attached to a belt or bum bag strap with the clip.

That said, they do look cool under the lid, and they are CE-approved impact resistant. £12.99
