Bruce Lee mentions quick seeing in his book and Masato was mentioned to have taken some sight training which enhanced his ability to see Zambidis punches. Usually you hear sight in reference to sports such as baseball and golf, is there much information on sight training for martial arts? Improved sight = improved reaction time? Some of the devices I see still are the speed bag and the double ended ball and some contraptions with balls on a ring, funky looking bats, which seem outdated. Are there any new interpretations of vision speed training equipment? Or is just plain old sparring the best method still?
