These are the most compact folding sunglasses available, small enough to slip into a pocket or belt pouch. Full-sized sunglasses when worn, they collapse to the size of a small cell phone--the sunglasses' len's fold inward at the nosepiece, and the two temple arms fold into the lenses--the tiny bundle slips into the included leather case that clips onto a car's sun visor for convenient storage. Thin, lightweight and strong, these sunglasses have scratch- and glare-resistant polarized plastic lenses that block 100% of harmful UV rays. Folded: 1" H x 1 1/2" W x 3" L. (2 1/2 oz.)
