I have been reading about people who have cured their own short-sightedness by combining dietary changes with either not wearing glasses or having glasses purposefully to weak for them. For example, The Cure for Blur, also here, and this site is a clinic in Austria that does much the same thing: The Frauenfeld Clinic.
The basic idea is that there is a strong association between getting too little sunlight, eating too much refined carbohydrate and simply wearing glasses that makes you more and more short sighted. The eyes are a natural system, like much else, and they respond to the conditions they face. If they are always viewing the world through glasses, then that becomes their frame of reference and you become even more short sighted. If you always focus close up then again that becomes their frame of reference, and you become short sighted.
I know I became short sighted as a teenager, at a time when I mostly ate brown pasta and spent a lot of time reading, and relatively little time outdoors. Since then my prescription has gradually got stronger.
So, in the last couple of days, simply by covering my eyes for a few seconds and walking about at lunchtime in the sun without glasses, my distance vision is already a bit better and my glasses feel too strong. I have been practising viewing my computer at the edge of blurriness (as recommended by the Frauenfeld site) too. So I am going to look into getting (as cheap as possible) glasses that are not quite strong enough, so my eyes will always have to work a little, then gradually changing the lenses to be weaker and weaker. Plus I am already eating less refined carbohydrate or sugar and more animal fat, so I will carry on doing that. They also think there is an interaction with sunlight, because we are outdoor animals and just built to be see things exposed to direct sunlight.
From what I can see, gradually getting more short-sighted is a response to wearing glasses, and initially a kind of being overweight inside your eye. It need not then be a natural state of affairs, and could gradually be corrected.
Am trying it, anyway.
