Review: A wise buy - Really nice glasses. Very stylish and flexible. Very light and comfortable to wear and they give you eyes very good HD view. I think these are in the class of Oakley's glasses. They are by no mean replica, but they have the same feel, at a better price. The lenses (not mirrored) keep your eyes private, unless they are two inches from your face. If they are that close, well, they earned the right to see your eyes...lol
Review: ... use while playing tennis and volleyball and they didn't disappoint. The weight is hardly noticeable - Bought these glasses primarily for use while playing tennis and volleyball and they didn't disappoint. The weight is hardly noticeable, the lenses don't glare as much as some other sunglasses in this price range do, and they fit my somewhat large face perfectly! I was able to jump and spike the ball with ease in the hot sun and when I started sweating, I found that there was no dripping on to the lens from the TR90 frame which had been a significant issue with previous sunglasses I'd owned. They performed well on the tennis court also: I had no trouble spotting the ball and yet was able to keep the sun out of my face. Glad I found these and I know I'll be sticking with them for a while. Highly recommended!

### ⭐⭐⭐⭐ A bit large on women
*by A***E on 8 March 2021*

I bought these for myself as I prefer polarized lenses and I liked the style. They are packaged very well and include a rigid zipper case and cleaning cloth. Very high quality. The only thing that prevented me from giving 5 stars is that they are a bit wide for my face, and sit a bit loosely around my ears. They were clearly made more for men. They don't seem to be adjustable in any way. The nose piece is totally connected and not adjustable, which I prefer because if I set them up in my hair away from my eyes, they won't get tangled up in my hair.
