Why not buy eyeglasses online?
Two optical shops offer very different argument. A said that as long as you take their multi-functional glasses, their glasses are able to anti radiation, anti-ultraviolet, and anti fatigue as long as you wear the eyeglasses. While another said that the length of time with eyeglasses will directly determine whether or not fatigue your eyes. It is not difficult to find that some glasses shop owners are not telling the truth.
The concept of anti-fatigue is just a concept, it is very difficult to identify which lens can be anti-fatigue, and there is no exact standard.
Glasses shop owners often say that the glasses have some additional features, they only want to sell their eyeglasses, but consumers did not see the relevant inspection reports, we must choose carefully.
