I had a pair of these, years ago. They worked great. They protected 100% from UV rays. I tested them with a UV flashlight (take a UV flashlight and shine through the lens, onto a UV reactive surface in a darkened room (American paper money has a security strip, that glows under UV rays); and if the UV surface lights up, you don't have 100% UV protection). These fit well under my glasses, but may be tight under small glasses. I like the side protection. These lens were clear (not 100% optical grade) and distortion free. The package did not say polarized, and I suspect that they may not be polarized, but they do help with the glare. The most important thing is UV protection to protect the eyes. By the way, most UV protection applied to glasses at optometrists do not protect 100% (test them yourselves with a UV flashlight). I feel a lot safer in the sun, with these.
