Every OTIS Rx lens is cut to your script and finished with scratch-resistant, anti-reflective and UV-protective coatings. Everyday Clarity CR-39 for acetate frames, Active Protection polycarbonate for our 6-base sun frames.
Note: We do not use mineral glass for prescription sun and optical lenses because the material does not allow for proper lens surfacing and edging, which puts prescription accuracy and effectiveness at risk.
