Since the Nature.com link just basically says "myopia exercises don't work"... NPR just had a piece talking about a 2-yr study in Sydney that found that spending time outdoors reduces myopia in children and a 15-year-old program in Taiwan to ensure primary school children are sent outdoors more, which has reduced their % of myopia. Theory is that we change our focus distance regularly when we're outside. ("hey look, a bird!" "i think i'll stare blankly at that tree while I ponder that document" etc) https://www.npr.org/sections/health-shots/2024/05/13/1250555639/kids-eyesight-myopia-near-sighted-nearsightedness-outdoor-play https://www.npr.org/sections/health-shots/2024/05/13/1250555... Notably -- I guess -- the study was about children. Maybe adults are screwed. It certainly is easier to get kids outside more if the govt is backing the changes.

Anecdotally, this worked on for me. It's not a great improvement, but it was noticeable.

The theory is not focus distance changes, but high angle high brightness overhead lighting (sun) and sufficient blue light.

  I've also heard the high brightness during the daytime helps with getting into a good sleep cycle by setting the biological clock to "ok now it is definitely day". Even when sitting close to a window, the light level is typically still something like 1/10th (or less) of what it is outside. Not that I do any of this; I enjoy reading long articles and writing code until 5am

They say "exercises", although most of the studies listed focused on various types of massage.
