I've only recently needed to get glasses and by needed I mean have any use for whatsoever. At my checkup I was told I had one step near-sightedness and the slightest astigmatism in my right. I was given a prescription with the doctor noting that I will probably only have to use my glasses while driving after dark. Well, I don't even drive, I take the subway and cabs where ever I go. However, I like my glasses. I think they look great on me and I've gotten nothing but compliments on my appearance with them on. A friend, who thinks I look better with them than without, though, has told me that if I wear them too often my eyes will get used to them and eventually my vision will worsen. This sounds like rubbish to me, but I have noticed that if I am in a large lecture hall and am trying to make out the details of my professors face it is noticeably blurrier than I recall it being before I started wearing my glasses. Is there anyway that it is actually true that I am weakening my vision by unnecessarily wearing my glasses or am I just falling prey to my own mind and only noticing this because of my friend's comment?
