Oval shape clip on sunglasses with non polarized UV400 color mirror lenses. These clip-on sunglasses 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. For the oval shape clip on sunglasses to fit your glasses, your glasses need to be similar in 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 frame width x height. The oval square 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 frame or the next size bigger. Say goodbye to the hassle of switching between your glasses and regular sunglasses – with our sunglass clips for men and women. All of our sunglasses and clip-ons are rated UV400 protection which is up to 100 Percent protection. Included microfiber carrying pouch.
