I actually had a teacher in junior high that promoted that theory. I dont believe she was right.
I see glasses as an aid or support but its hard to tell sometimes because meds weaken the muscles in the eyes as well, meds give me dry eyes and I need a little help and a reactive tint because my meds also make my eyes sensitive to light,
I like taking my glasses off some times to let my eyes breathe as well, probably sounds weird but its nice sometimes.i did it today when I was out on the riverside watching the water glisten/shimmer.
