Is it feasible to take up martial arts if you are short-sighted and wear glasses? Or are contacts the only way? In my case, I can see things that are reasonably close to me and would probably be ok without them doing one-on-one techniques, but would have to put them back on to watch the instructor demonstrate techniques and see anything else far away. The main arts I'm considering are Krav Maga and Silat. Any other speccy gits out there with similar experiences? Thanks, Pach.
