Look through the lenses. Fake eyeglass has no prescription, while real eyeglass has prescription. If you have bad vision,then you put fake eyeglass on and you still can't see clearly.If you have perfect sight and put real eyeglass on , then your sight won't get so perfect and you will find everything is blurry.

The main purpose of fake glasses is to help your eyes from the radiation from the computers or just make you look better. They are widely used for the office men who are right at the vision. However, about your realness of fake glasses, you could bring the eyeglasses to the store and ask the client. Their professional machine will help you check its realness.
