Can wearing the wrong kind of eyeglasses damage my eyes?

Eyeglasses are devices used to sharpen your vision. Although correct eyeglasses or contacts help you to see clearly, wearing a pair with the wrong lenses, or not wearing glasses at all, will not physically damage your eyes but may cause eye fatigue or strain. However, children less than eight years old who need eyeglasses should wear their own prescription to prevent the possibility of developing amblyopia or “lazy eye.”
