Warby Parker Harris Tortoise Shell-style Rx +0.75 Reading 。Warby Parker Harris Sunglasses in Medium (normal) width, in the tortoise shell color called \"Oak Barrel.\" These shades can also serve as reading glasses if you like to read outdoors because they have a prescription of +0.75 in each eye - a mild prescription for farsighted eyes who need just a little help to see things up close. Harris is a classic, timeless style that makes an homage to vintage style with the tortoise shell-like coloring and the reference to Ray Ban shades. This design has some beautifully simple, elegant lines and curves mixed with just the right amount of subtle, structured shape. The accent silver studs on either corner are a great detail to bring the whole design together. Lenses have no prescription; they are UV400, meaning they block 100% UV rays. Made from hand-polished cellulose acetate Prescription lenses are made from polycarbonate, the most impact-resistant material for sunglasses; non-prescription lenses are made from CR-39 for maximum clarity and color Frames width at the front: 136 mm Width of each lens: 47 mm Width of bridge: 20 mm Length of each temple (leg): 145 mm Very minor scuff in one place on the frames - they are otherwise in excellent condtion, super glossy and well-built; the lenses have one eyelash-thin scratch on one side and a few other smaller, very minor scuffs. Overall, none of these are very noticeable and they look great.
