Sleek and lightweight, the Streamline series eliminates harsh glare and distorted vision while fitting comfortably and securely over your prescription glasses. To prolong the life and maintain clarity of the lenses, they are polarized with Polaré® and hard-coated, scratch-resistant and engineered to withstand the rugged demands of fishing and boating enthusiasts. They deliver 100%, 360° UVA and UVB protection and crystal-clear visual acuity. Polycarbonate side shields are permanently molded into the frames and will never loosen or fall out. The Flex2fit™ temples easily adjust for a secure custom fit, while the ultralightweight Soft Touch™ frames are so tough, they carry a lifetime warranty against breakage. The Streamline fits over frames 4-7/8"W x 1-3/8"H.
