depth perception...

A conversation was sparked maybe a week or so ago by Journeyman at Japanese Jiu-Jitsu. The subject was training while blindfolded and it brought to mind an article I read a few months ago in a martial arts magazine (which one, I don't know). Anyway, the instructor was suggesting doing technique and even light sparring with one eye closed/covered, as it really throws off one's depth perception. The idea is to simulate an injury to an eye, or more likely, a cut near it that is impairing the vision. He suggests it becomes a much different game, using one eye, and could be a useful drill to hone balance and perhaps save your butt if the situation ever arose (he's likely referring more to ring and cage fighters, although I would think it could also have defensive implications).
If you try just to close one eye and do stuff around the house you'll see what I mean. You will adapt, but it takes getting used to (and adapting fast is good defense).


  1. Another thought is to practice sparring or randori while wearing hearing protector or earplugs to simulate the deafening effects gunfire or explosions. Hearing is integrally related to balance.
