ClipOn sunglasses are an affordable alternative to polarized prescription sunglasses. Simply attach the ClipOn frame to your favorite eyeglasses or readers for 100% UVA-UVB lens protection, reduced glare, and enhanced contrast for a sharper, more comfortable view. Rimless ClipOn styles work best for thicker plastic frames and rimmed ClipOn styles work best on metal frames. Not sure what size you need? Visit our Fit Guides to find the size that’s right for you.
