A new app called 'Ultimeyes' claims it can train your eyes to improve your vision. You can choose exercises for near or distance vision. Here's how it works: Users click on a series of targets on their computer screen. The developers, Carrot Neurotechnology, claim if you practice for twenty-five minutes a session, four days a week, your vision will improve. You can download it for $6 for your PC, Mac or iPad. Some University of California-Riverside baseball players who tried it reported their vision improved more than 30%. The problem I see, though, is the reviews in the app store are not so good. But for $6, I think I'll try it.
