I remember my eyesight was 20/20 all my life until I started playing more and more with phones and tablets, now I can barely see any font in a regular browser tab at 100% zoom so I set it to 150% by default.

One thing that changed for good is using a 50" TV as monitor connected to my mac mini at 4' distance from my chair. Now my eyes don't cross anymore and my sight has improved a lot.

So yes, I concur that looking at clouds and the horizon everyday may be a good way to recalibrate our eyes. Spend more time outdoors.

[edit] Oh, and whenever I can, I cast my phone to my tv in the bedroom so I don't spend countless hours on tiktok forcing my eyes. I wish tiktok and instagram were available in landscape mode.
