Contacts for cosplay?

So I've been thinking of going to ACEN next year and possibly cosplaying. Since I wear glasses, I've been told that my choices are rather limited. So here's my options, go as a character that wears glasses, or get contacts so I can expand what I can do.

For people that have contacts, what's it like? To be honest, I feel that it'd be really...weird to have that stuff on my eyeballs. Maybe it's just a fear of rubbing my eyes and just shattering the lenses and getting that stuff in my eyes >.>

For my second question, who could I cosplay as if I do go with just using my glasses?
