Review on AODUOKE Polarized Sports Sunglasses for Kids - Adjustable Strap, Ideal for Boys, Girls, and Youth by Carlos Henley

I bought two of these glasses for my nine year old twins. These goggles are VERY flexible, to the point where you absolutely have to use a strap or they will just fall off your kid's face due to lack of rigidity. Although our boys love them. One pair was quite twisted when they arrived but I took the lenses out and heated the frames with a heat gun to reshape them and it worked like a charm. If your child doesn't mind using the harness every time they put it on, then this is a good option.
