I just got glasses and am a bit hesitant to wear them because they start ruining your eyesight if you wear them all the time and make you dependent on them. I was wondering if contact lenses do this to your eyes too. I used to wear contact lenses and I don't remember this ever happening. I used to wear them all day long. Of course my prescription nowadays is much stronger than it was back then, so I don't know if that has something to do with it.
