According to the Bates theory as reported by Quackenbush (“Relearning to See”), errors of refraction are just defects in the image on the retina - caused by muscle imbalances in and, particularly, around the eye. And since, in general, those imbalances were probably learned, their correction should also be learnable with practice.

In my case my eyes became “needing” about -4 diopters (with about +2 for astigmatism) correction in both eyes (from +0) over the summer at about age 12 – a growth spurt. At about age 40 my correction started going down (to about -3) and I needed bifocals. Then trifocals at about age 55. About 2 years ago I got tired of head-bobbing to find the right focal and got two monofocal glasses, and around the same time I bought the Quackenbush book. The near vision glasses I ordered specifically +0.5 over the eye doc's measurement, and the far-vision pair about -0.5 (under) his measurement. That was so that the two ranges would meet at my computer monitor about 3 ½ feet away where my near glasses have my eyes relaxed. At great distance with my far glasses my eyes would also be relaxed. The result now (age 66) is that my far correction is down to about -1 (astigmatism is about +1), my near correction almost 0, and I can use either pair comfortably at monitor distance.

Thus, relaxation can work in teaching the brain for new balances for the eye muscles, but I think you may have to just keep pushing the envelope where your vision is almost in focus like I did. If the image is too blurry your brain won't be able to figure out how adjust your focus muscles to improve your vision.

I think that appropriate exercises can also work, and I suspect that they too might take time.

BTW and for full disclosure, during the last two years I have also been testing the effects of nutrients on my glaucoma and cataracts (not for refraction – but I don't know if they made a difference). For me the cataracts went away in less than a year (both eyes; first evidence in a week) with 100 mg of alpha lipoic acid per day. Last week the doc said I've got new ones … so I doubled the dose. The glaucoma (by retinal, optic nerve, and visual field evidence) went away after I started fish oil (EPA and DHA omega-3s). For others the same nutrients may not be the problem, and it's worth knowing that I was already taking extra vitamin C, D, E, and 12 mg iodine-iodide (Lugol's soln.). That's on top of a Paleo diet for ten years that is mostly raw, organic vegetables, sprouts, fruits, nuts, fish and fowl.
