I'm curious how many of us require corrective lenses of some sort or the other... Be that contacts, glasses, or whatever. If you have had laser eye surgery, please select the 'corrective lenses' option. And, how has this affected your photography? I wear contacts and glasses (not at the same time, lol). I find that while I'm wearing glasses I have to remove the rubber eyecup from the viewfinder. That let's me get my eye closer, and also avoids the smudges I always get from it if I don't.
