For the price,  you can't beat them. They are very clear and feel great. They aren't too tight and dont pinch but don't move or slide around at all. They stay right in place. They are also very light and comfortable. I could barely feel them on my face. I use them when I go golfing. I usually take sunglasses off to swing and putt because the frames distract me but with these you can't see any part of the frame in your peripheral vision.  Overall,  they are awesome for the price you pay.
