These are polarized clip-on lenses that attach to prescription frames and flip up when you go indoors. The TAC lenses are UV400-rated and cut glare from roads, windshields and water. The magnesium-alloy frame is light, and the magnetic front attachment lets you mount or remove them with one hand. They suit drivers, anglers and anyone who wants sun protection without a second pair of glasses. Against dedicated prescription sunglasses, they add bulk to your frames and depend on a secure fit, but they cost far less than a second pair and switch between clear and shaded in a second.

This flip-up polarized clip-on attaches to the front of your prescription eyeglasses with magnets. It turns them into sunglasses without a second pair of frames. You can attach it with one hand.
The lenses are polarized and rated UV400, blocking 99% of UV rays. They cut glare from roads, windshields and water. A multi-layer coating makes the lens surface scratch-resistant. The frame is lightweight alloy.
The lenses flip up halfway or all the way when you move into shade or go indoors, so you don't need to remove the clip. Each oval lens measures 2.4 × 2.1 inches and fits most medium to large prescription frames.
