How do you know about kids sunglasses?

[cheap glasses]

Do you think kids can wear sunglasses or even prescription sunglasses at summer? I just want to know if sunglasses are suitable for kids, as there are always two kinds of sayings, one is that 90 percent harm rays of one’s whole life accumulate before the age of 18! So, your children's eyes may suffer long-term damage if those glasses do not provide the effective UV protection! And there’s another saying: kids’ cornea is not as mature as *****s, so they still need the sunlight stimulation, So, what’s your opinion, can I buy sunglasses for my kids?
