I recently caught an elbow with my left eye when I collided with one of the ukes. There's no damage to the vision, only mechanical damage (which is very visible) In view of this accident I'm thinking of getting protective goggles, as I also wear contacts (I was when the accident happen and they did not aggrevate the injury). I was wondering how frequent eye injuries are in Aikido (I'm not talking about nose injuries that cause black eyes, I'm talking a direct hit on the eye-ball). Maybe there's a place to recommend contact users to use goggles. If you ever had such an injury or witnessed one, I'd like to collect some statistics.
