Isn't myopia beneficial? When eyes get adapted to screens, books maybe it's bettter? I can see every single pixel on screens and it's very useful in daily life. Far sight is useful only rarely - when driving, and when hiking in mountains. And near sight worsens with age, maybe previous myopia slightly prevents that. On quora they agree https://www.quora.com/What-are-the-benefits-being-short-sighted-myopia https://www.quora.com/What-are-the-benefits-being-short-sigh... Thanks for reminding me about myopia, I will get glasses (if anything, just for mountain views). One time I tried someone else's glasses and it was wonderful, completely different world when being outside, extremely sharp, not blurry.

No, I have -4D and can't see a screen clearly from more than 25 cm.

  I have -5.50D and to be honest, whilst my vision is pretty poor I can definitely tell that, when not wearing glasses, my close-up vision is better. Not that it's actually helpful.

I have a hard time believing that’s better than seeing both with absolute clarity, which is certainly possible.

  If you are young and able to focus anywhere, then I guess that's better. But possibly there is myopia and presbyopia (age related farsightedness) interaction. "Many people with near-sightedness can read comfortably without eyeglasses or contact lenses even after age forty." "Presbyopia is the result of age-related hardening of the natural lens. Everybody has this happen and it gets bad enough we can’t ignore the resulting near vision problem by about age 45. The one good thing about being near-sighted is that the large eyeball means the default focal point of the myopic Eye is up close, depending on how nearsighted you are. So if myopic, without glasses you can see up close without needing to work at it."
