I have learned today why people who spend their days in libraries, wear Glasses.

Natural vision therapists like Meir Schneider have been advocating along these lines for decades, but now the ophthalmic establishment have just woken up, it's a big revelation.

this is horsehit. I’m the ONLY one in my family who is myopic, -3.50 in both eyes, no one else even wears glasses.
I spent way more time outside than any of my siblings, i’m the only boy. and I was at the pool all day long or out riding my bike playing in the neighborhood from sun up to sun down all thru the 1990’s…..

they still don’t know what causes myopia and can’t seem to admit it
