This is a pair of unisex memory plastic full-rim eyeglasses. They feature extreme lightweight, super-shape-retaining durability and high heat-resistance, bringing you an unpredicted comfort for all day long wear. These glasses can protect you from attack when doing outdoor activities and workout but just weight up to 50% lighter than acetate frames. The frames with modified rectangular-shaped lenses reveal a youthful and artsy look. The rectangular lenses allow single vision correction perfectly. The total weight with lenses is 13g.
