Is it sunny outside and would you like to wear sunglasses, but you already have regular glasses! Then these black clip-on sunglasses are perfect for you! You can easily attach the clip-on to the bridge of your glasses with the plastic clip on the back. The clip-on has polarized lenses, reducing glare from bright sunlight and the UV400 filter will protect your eyes from harmful UV radiation. If you sit in the shade for a while or the sun disappears behind the clouds, you can easily flip up the clip-on without having to take it off your glasses. A true must-have for all glasses wearers on sunny days!
