Can I buy sunglasses for my kids?

[glasses prices]

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% harmful 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?
