I live in Bangkok but I'm a Canadian citizen. They is a lot of fake stuff here. Believe it or not, one can even get stuff that is a sometimes a knock off inside an indoor shopping centre.
Anyway…
I'm going to get new lenses for my eye glasses as my existing lenses do not have UV protection.
Is there a way to know if they gave me a cheap pair of lenses that do not actually offer UV protection? Would an optician/eye doctor in Canada be able to know by looking at them?
