Glasses without lenses? as in fake ones? why would you want them? U can just go to a 3d movie, get a pair of those and pop the lenses out.
Yes. Very.
the glasses that you wear have lenses
When you say "glasses", it is plural. A "glass" is one of the lenses. "Glasses" would refer to both of the lenses, and a "pair of glasses" doesn't mention anything about the frame, but it mentions the two lenses. The frame is the object that joins the two lenses so you don't have to wear contacts and so it can stay on your head. When you say "a pair of glasses", you are referring to the "pair of lenses", not the frame. The frame holding the two lenses makes us think that it is one object, when the word "glasses" refers only to the lenses, not the frame. That is why it is called "a pair of glasses".
no
The purpose is that you don't wanna have glasses or you want your eyes to be a different type of color.
Contact lenses is another way to correct vision besides wearing glasses. I am nearsighted and can't see anything without my glasses. It corrects my vision and I don't have to worry about having my glasses break
