Smith’s Attack glasses have a new and easy way to switch between lenses. The temples connect to the lenses via alligator-like clips, part of the company’s Mag system. To remove a temple, bend it at the hinge, and unclip. Simple. Swapping the nose piece is easy, too. The Attack comes with two lenses, one for bright conditions and one for overcast days. All use Smith’s Chromapop technology, which filters out certain light waves to reduce what the company calls “colour confusion” and to give you a clearer picture of the road ahead.
