Oval shape with NON polarized UV400 color mirror lenses. These are very nice quality, they have a color mirror coating but the lenses themselves are gray. Non polarized lenses make it easier to see your dashboard and electronic devices outside, the mirror is for that cool look. For the oval shape to fit your glasses, your glasses need to be an oval shape with your frame rim measuring less than 3mm's thick. Please measure one lens of your glasses carefully to the outside rim of your glasses width x height. We have many different sizes available and only one will fit your glasses, so it is very important to measure your glasses correctly. The oval shape needs to be NEARLY THE SAME shape as your glasses and the size clip-on sunglass needs to be the same as the measurement of your glasses or the next size bigger. To help with sizing, we have printable templates for the oval shape at Sunglass Rage but there isn't a way to upload the templates here so measuring your glasses carefully is very important. All of our sunglasses and clip-on's are rated UV400 protection which is up to 100% protection. We include a microfiber pouch to store and clean your lenses.
