I tried contacts for a couple of months once, and I could just never get used to sticking something on my eye ball! Also don't get polarized.

BTW N618FT, I had problems with my glasses digging into the side of my head wearing all the old typical head vise style head sets, not to the point of head aches, but it was uncomfortable. However that problem went away when I bought my Bose head sets. They have light enough pressure on my head that they don't cause my glasses to dig into my head.
