The Foster Grant Solar Shield REC M is a rimless rectangular clip-on that turns prescription glasses or readers into polarized sunglasses. It fits plastic and thicker frames, blocks 100% of UVA and UVB, and uses scratch-resistant polarized lenses to cut glare. It suits people who want sun protection without a second pair of prescription sunglasses. Against dedicated prescription sunglasses it is lighter and easier to carry, but owners report the clips are the weak point and can snap with regular use.
