REI Outlet offers the Native Eyewear Unisex Blanca Polarized Sunglasses in Maple Tort / Brown for $31.73. Opt for in-store pickup to avoid the $5.99 shipping charge. That's $97 off and the lowest price we could find. They feature polarized lenses that block 40% of infrared light (purportedly decreasing eye fatigue), UV protection, and blue light filtering (to minimize haze). Deal ends August 13.
