We have a large assortment of clip-on 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 hooks are designed to rest on the top rim of your glasses with a spring in the middle for tension. The hooks have rubber or plastic coatings to help protect the lenses. We do not recommend clip-on's for rimless or semi-rimless glasses. For help finding the right size clip-on, we recommend that you email us a scan of your glasses following the instructions found on the link below. Start here by following this link.
