Polarized sunglasses by Suncloud. NWT Perfect classic styling! If you are new to Suncloud sunglasses, you will not regret trying them. They are durable, quality, comfortable sunglasses at a great price. I have many pairs (and in this case, my over-ordering becomes your bargain!) POLARIZATION Through advanced lens technology, Suncloud polarized lenses selectively filter horizontally reflected, visually interfering light waves known as "glare". The elimination of direct and ambient glare results in superior visual clarity, definition, color transmission and comfort. LENSES Polycarbonate material provides a great blend of impact resistance, optics, and are lightweight so you can comfortably wear them all day for your sport performance needs. All Suncloud lenses provide 100% protection from harmful UVA and UVB sun rays.
