Allegedly there is a way to correct nearsightedness, and for what I have read, the methodology and the reasoning seem convincing. The method involves actively focusing on objects far away. Preferably, the objects you look at should be 6 feet away or further, but there is not a considerable difference between looking at objects past 6 feet compared to hypothetical objects infinitely far away since the difference in focus for your eyes is 0.2 diopters.

When you look at objects far away, the muscles inside your eyes relax. Those muscles are the ciliary muscles, and they pull on the lens to focus your sight.

Unfortunately, after looking at objects that are close-by for too long, the ciliary muscles become permanently contracted and the eyes are unable to relax, meaning that far away objects look blurry. The worst part is that when this happens, people get near-sighted glasses, which work for some time, but over time these glasses worsen the problem because they ciliary muscles must contract even further in order to look at close-by objects. This leads to a cycle of getting new glasses each time the eyes become more near-sighted.

If I understand what I read correctly, according to the wiki for fixing nearsightedness, wiki.endmyopia.org, the solution to improve vision is simply to get progressively weaker glasses, which the wiki calls normalized glasses, and put up with the blurry vision while looking at objects that are 6 feet away. Eventually your ciliary muscles will relax a little, meaning that the blurry vision will improve a little. After that happens, you get slightly weaker glasses to make your vision slightly blurrier. This, again, stimulates your eyes to relax and improve.

I actually tried this method myself and I want to say it worked, but I am not 100% sure myself since I never got glasses prescribed. Basically, I was noticing that my left eye vision was getting blurrier. I could barely read the time from my computer monitor’s clock. The distance from my seat to my monitor did not change, so I knew my vision had worsened.

So the way I went about improving my vision was that I bought a presentation clicker. The Back < and Next > buttons on the clicker were mapped to Page Down and Page Up on the keyboard, so I used the clicker to scroll from far away.

Initially, I was using a wireless keyboard for scrolling, but I only needed the Up and Down keys for reading.

This meant that I could read books while lying on my bed, making the distance between my computer monitor and my eyes about 6 feet. If the text got too blurry, then I changed the zoom to adjust the text size.

After a few weeks of reading like this, I could use my left eye to read the clock time from the computer monitor again.
