Review on Protective FONHCOO Blue Light Blocking Clip on Glasses: Reduce Eyestrain & UV Glare, Perfect for Mom, Dad, Wife, and Husband by Gary Newman

Very good price, fast delivery, good product. Easy to attach to glasses, very light. At first I thought they were of poor quality, but they are not. I had to bend the mount on a couple to clear the middle or bridge of the nose. Stays in place very well. Can't say it's good enough. The only downside I see is all the extras in the package. No real need, they could lower the price a bit more. But they are not expensive anyway. All in all a very good product at a reasonable price.
