We have a large assortment of clip-on and flip-up sunglasses. Our clip-on sunglasses come in polarized and non polarized UV400 lenses. Polarized lenses are lighter weight and eliminate more glare. The clip-on attachment tabs are designed to rest on the top rim of your glasses with a spring in the middle for tension. The tabs have rubber or plastic coatings to help protect the lenses from damage. We do not recommend clip-on's for rimless or semi-rimless glasses.
