Fantastic glasses,had one pair for over 3 years now,they still hold up pretty well,the craftsmanship is exceptional and the materials are good quality. Decided to buy another pair just in case something happens to my favourite pair.If you're looking for a stylish and functional anti blue rays glasses don't look any further,get these! Seller did a good job too,and pricing is top,buy with confidence. Good work Qukan!
Good quality glasses, I'm satisfied. But for now, I can't feel the photochromic effect, probably I don't understand something
