There's a belief corrective eyeglasses are unnecessary. For example, a woman with schizophrenia needed glasses as one character, but did NOT need glasses when she was "someone else". The point being, if poor eyesight was truly a physical eye need she would ALWAYS need glasses regardless.
Many, many years ago, the method to wean oneself off glasses was developed by Dr. Bates. The Bates Method, as you will find on the internet, was SO successful the Optometry Industrial Complex, for the lack of a better term, made the method illegal.
I'm farsighted. For years, I had been using mild, corrective, US$10 reading glasses. But, after learning about The Bates Method,, I've been been successfully weaning myself away from needing to wear glasses.
Here's an excellent summation of The Bates Method, which is rather easy to learn. There are Bates Method classes, but I just snooped around the internet and found enough details to do it myself.

Oh. I assume The Bates Method works for nearsightedness. I'm farsighted, so I can't test.
