Mid 20s here. Lived like shit until like 2 years ago. Started working out and eating right. In the best shape of my life.... then got diagnosed with an aortic anuerysm cant win

My vision had started to decline in my 30’s. Not a ton but needed glasses for distance vision to be crisp. When I hit 60 I started to operate without my glasses more. It forced my eyes to work more. I just had an eye exam and I can legally drive without glasses. My eyesight improved. It’s not crisp at distance but I can grab my glasses when I feel the need ( use when driving at night for extra layer of safety)

>after a lifetime of perfect vision, one day I was reading a book and noticed that everything was a little blurry

go to an ophthamologist and after testing you'll be told that you still have perfect vision! (the need for reading glasses after a certain age is considered normal, not a defect)

As I'm well past my mid-40s, so 100% :)

The best tech tool I've ever bought was a pair of dedicated computer glasses (focal length ~3ft) --for every computer I work at.

Hah gentle, my vision distance also started degrading slowly but I had no issues otherwise. Text etc. was a bit blurrier but I could still read everything fine, except when it was too close to my eyes.

Then one day I pretty much hit a brick wall and went from 0 to 100% eye strain in about 2-3 days. Now I need constant eye drops, a humidifier, breaks every 20 minutes, time spent doing other things etc. to just be able to do what I did before.

I mean, of course exercise isn't going to fix your vision. But if your vision is going to degrade, you can still choose if you want to live as a fit and healthy person who needs reading glasses, or as a person who has aches all over, is in bad shape, feels tired and like shit all the time, and on top of all that needs reading glasses.
