Even if you don't do the eye exercises, it IS fun to watch Paul McCartney cross his eyes and such.
I've been researching the Bates Method and such, for a couple years now, to try to improve my vision. But I admit I've been too lazy to stick with it long enough for improvements. However, my eyesight is now getting SO BAD that I'm going to stick with it, even if it's just these small yoga exercises Paul McCartney has. I've had just way too much computer and book time, not good for the eyes. It's also been hard to try to stick with the Bates Method because they say to avoid wearing your glasses as much as possible ... which I can't do because I'm for all practical purposes blind without my glasses my myopia is so bad (probably something like a -7.5) that I just can't function with everyday things without them. But I'm going to persevere!
