Ultra-large lenses give the Anon Josie Sunglasses all the coverage you could ever want out of a pair of shades. If these Anon sunglasses were any bigger, they would be called goggles. Despite the large lenses, the Josie Sunglasses feature a medium fit, so they'll actually stay on your head. Optyx Decentered lens material resists scratches and weighs less than glass. After all, these Anon sunglasses would weigh a ton if they had glass lenses. And no one wants that.
