The Otus does away with harsh angles for a softer square-frame design. Available for purchase as regular sunglasses with tinted polycarbonate lenses or have clear lenses installed through your doctor or by us and use the magnetic fronts to provide tinting in bright environments! Every purchase of Flying Eyes eyewear comes with a hard case, microfiber bag/cloth, and a Flying Eyes sticker. Mirrored lenses are only colored on one side; there is no color distortion while wearing.
