Dear customer: The polarized lenses will help a lot when driving. They could filter most of the glare that hits your windshield when driving into the sun.

100% UV400 rating, protect my eyes. They are the best I have ever bought.

It depends on the size of your son's head. I think they'll be good because they fit my little head.

Wonderful quality and vivid colors for choose,can't match the grass anymore.

Plastic lenses with mirron coated.

I have the polarized sunglasses in jell brown color on the beach,for me ,it's more like crystal orange and I can't like it anymore.

I prefer the green and white colors.White as clouds,green as sea.
