Are you talking about those magic eye 3D things?
Those really work if you're near sighted.
I was really into those when I was a little kid, and after looking at them several hours a day, I became far sighted for a few years.
But after using the computer for years, I've become a bit near-sighted now.
I need to get those magic eye books again. Not as interesting now as it was when I was 8.
I sure hope you're joking.
You aren't going to change the optics of the eye by doing exercises, palming, See Clearly, or any other method.
Just like how you wouldn't change the optics of the eye by staring at books 5 inches away from your face? :roll:
What you are referring to is called accomodation. The ciliary muscle contracts, relaxing the suspersory ligaments, resulting in an increase in the lens curvature. This results in a shorter focal length, necessary for near vision. The opposite happens for far vision.
This does not change the shape of the eye. Farsightedness (hyperopia) results from the eyeball being too short. Nearsightedness (myopia) results from the eyeball being too long. No type of exercise will change that shape.
By the way, presbyopia, where the lens becomes stiff with age, means that the lens cannot sufficiently accomodate for near vision. This is why reading glasses are eventually necessary for everyone who is not near-sighted.
