As soon as I received them, I put them on and went outside to check them out. They eliminate the glare beautifully. When bicycle-riding with regular sunglasses, there is still a terrible glare; these nicely eliminate that glare. They fit perfectly and snugly, and the wrap-around feature takes care of any glare that would otherwise enter around the lenses. They are strong and virtually weightless and are the solution to my sunglasses need. I am extremely happy I made the purchase, and I now have two pair that arrived in well-designed packaging that kept them perfectly safe from any damage in transport. I highly recommend them as something you will wonder what you ever did without them.
