LUFF Clip On Sunglasses Polarized Cat-Eye for Men & Women, UV400 Protection, HD Anti-Glare | Safe Driving, Cycling & Outdoor

Clip right on to my glasses - easy to attach. The polarized lenses are slightly larger than my glasses lenses - but they work well. Easy to flip up when not needed. Great value alternative to prescription sunglasses.

They clip on rather easily to my glasses. Though I will say my glasses are a bit smaller than these clip-ons, but it works. I love I can flip them up if I don't need them. They work great to keep the sun glare out of my eyes. The reason I wanted to try these is because I don't want to pay for prescription sunglasses so this is a great alternative.
