Well I also have to wear glasses but I cant really wear contacts because they bother my eyes (I get the same ichyness in the eyes that you do so you might be botherd by them too) and my brother also used those 30 day ones and ended up with an infected eye! (But it got better) It got infected because he did lots of tomato picking and there is HEAPS of chemicals and dust blowing around those damn farms. Anyway... If your curious I think you can get a free set of 30 day ones to try out or you could just get some one day disposables and see how you like those.
Hope I helped.
