I used to compete in karate as a kid and it wasn't an issue. In college I tried boxing but at that point it became apparent. Anyone who has it should no what I mean when I say its a strange feeling to do sports with this condition. It as if I see best when im not focusing on anything and I have to fight this unconcious physical urge to look away. ALmost like Roy jones Jr but not on purpose haha. Anyway is there any writing on how boxers who have suffered from it adapted?. Being conscious of the tendencies caused by my eyes has helped. It has not gotten me in big trouble or anything but I figure it is something I should address and understand.
