From the age of around 11 till the age of 23, I wore glasses and contacts.
At my worst, my prescription was -4.00, with astigmatism.
For the most part, I thought little of wearing glasses. It was just something I needed in order to see. It was mostly normal to wear glasses, other than somewhat of a nerdy/distant feeling I got while wearing them. When I went to the eye doctor as a kid, because I couldn't read the board in class anymore, I don't believe there was an assessment of my sleep habits, stress, strain, relaxation, coordination or something like that... it was just...
Does that sound like your story?
But what if the reason my vision was blurry was because I was stressed or coordinating my eyes wrong?
What if my genes, that had evolved for so many generations, were not actually coding for vision so bad I couldn't see clearly a few feet away? (Plot twist: It wasn't my genes that made my vision blurry, and your genes probably aren't making your vision blurry either)
I had at least heard about natural vision improvement when I was in 9th grade, but I didn't set out to actually try to improve my eyesight naturally until age 21 or so when my glasses got knocked off my face in a game of basketball and somehow I did better without them. But I didn't immediately start to work hard to improve my eyesight, because I didn't really feel it's possible.
At age 23, I began to study eyesight improvement in earnest.
I read a book from a man who was congenitally legally blind, Meir Schneider, who learned the Bates Method of Dr. William H. Bates, and that led me to consider the basic premise of the Bates Method - that eyestrain causes blur and relaxation and proper coordination of the body restores clear vision.
The fundamentals of Bates' theory appeared quite sound to me.
Two years after starting to learn about vision improvement and apply the lessons sincerely, I learned to improve my eyesight enough to fully rid myself of the need for glasses or contacts . I went from a -4.00 to a -2.25 to passing the driver's test which is close to a -1.00 or better vision requirement.
However, passing the driver's test in 2009 was not a full "cure". I've been working to improve my coordination and clarity ever since.
I see these all as skills to develop, as well as natural abilities to uncover and remove from all hindrances inside or out.
Theoretically, it's a very simple concept. The extra-ocular eye muscles squeeze and lengthen the eye - turning it myopic.
Releasing the excess squeeze allows the eye to return to an emmetropic shape.
The catch is that changing the shape of the eye is a natural and normal process that occurs on a daily basis - so you can't simply just "fix" your eyes. You must learn to properly coordinate them in the moment... forever.
People commonly point to genetics as the cause of poor vision, and take this as some excuse or reason why eyesight improvement is a dead-end... but does it make sense to blame genetics when since the not too distant past rates have increased as much as ten fold?
The study shows people of the same ethnicity with VASTLY different rates of myopia. What explains it? Lifestyle. Environment. Not genetics.
Is it really reasonable to believe entire majorities populations evolved to not be able to simply see without glasses, contacts, or LASIK technology?
To me, it's a simple claim. People are using their eyes (and bodies in generally) out of alignment with what the body needs.
Give the body what it needs, and the body will produce appropriate results.
As for putting this in practice, there's much to discuss about living a healthy life in alignment with physiologic needs in order to thrive.
