Why are glasses called glasses when they are really made of plastic?
Readingmaniac
Technically, if they are made of plastic, then they aren't glasses. They might be fake glasses, for diguises etc... Often, real glasses do have a thin layer of plastic over the glass so that they don't crack, but plastic doesn't do anything as far as focusing a person's eyesight.
