I've been thinking about the idea of changing eye color as mine is pretty, blah. Now, I have damn near perfect vision as it is. No glasses, never wore contacts, never had surgery... Anybody use colored contacts strickly for asthetic purposes? How do you go about obtaining a set? Will a set of non-corrective lenses hurt my vision? I'm not talking about wearing these 24/7. Just out on weekend nights and such.
