I heard that the every glass have a pair of fake lenses. Only if you want to restore a pair of prescription lenses, the optician will make a pair of prescription lenses according to your prescription. I also heard that a pair of fake glasses will charge us more than $200. Oh, my god! That's a lot of money. I won't spend that money on a pair of fake glasses. I have mild myopia. I can buy two pairs of prescription glasses from online optical stores with that money.
You can have a look at walmart, lenscrafters or Firmoo. The glasses sold in these places are very cheap. Nowadays many people wear a pair of fake glasses for fashion. Some of them just want a pair of glasses without lenses. But some want to buy a pair of fake glasses with fake lenses. The lenses will not cause great damage to your eyes. So every pair of glasses has a pair of fake lenses. If you don't need the lenses, you can take them off from the frame.
