Summer, and I want to buy my son pairs of sunglasses, but I have friends that hurt the eyes, consult the relevant doctor, and some say there are injuries, some said nothing, and made I do not know how to run you bought yet? What can share ah?

I gave my daughter bought a sunglasses, good looking, when you buy carefully try not to bring is the lens up and down Move glasses to see objects have not changed, because some children wear sunglasses too will feel the first intoxication, and may be the degree of lens wear, or not doing well, basically on the outside occasionally Dai Dai, or can.
