Counter anecdata. I'm 39, right eye slightly myopic since I was a kid. Never needed glasses. Always prefered using the computer in the dark since when I was a teen and had an NEC MultiSync CRT monitor. My eyes are still OK as far as I can tell.

40s are pretty rough when it comes to vision. At 39 my vision was perfect. At 47 I still have 20/20 father away than arms reach but closer than that it’s crap. When it started to change it was quick.

Is it common for people around 50 to get Lasik or a similar procedure to counteract this?

Women say they love mens eyes. So you have to work those out at the gym as well. I do eyelid lifts and eye rolls. 3 sets of 20 6 days a week with a rest day on Sunday. You can do these while on the treadmill and doing other excercise to increase efficiency. You can also mix in some beta carotene into your protein shake to really maximize the eye pump.

Supplements may have an effect, so for example taking beta carotene while being a smoker may be counterproductive:

> Among current smokers, beta-carotene supplementation was found to be significantly associated with an increased risk of lung cancer (odds ratio [OR], 1.24; 95% confidence interval [95% CI], 1.10-1.39).

Since march of this year I stopped following my eye doctor's advice ("wear your glasses as much as possible otherwise your brain gets lazy", which is proven BS) and looked into endmyopia (i think i even read about it on HN), as I was getting into the risk zone for retinal detachment (6 diopters), which can lead to blindness.

To sum it up: reduce the amount of near-work you do (looking at your monitor, smartphone, books, etc) and, if you already have glasses, use glasses with a reduced prescription or no glasses for near-work.

With these rules I've managed to go from -5.5/-6 to -3.5/-3.75 in just these 9 months. And that's with me still spending 12h a day on my computer.

Pro tip: you can get very cheap (as little as $3) myopia glasses from aliexpress or a bit more expensive zenni optical. So there's really no big barrier to entry.

Side note: Lasik only cures the symptom of bad vision (just like glasses), but not the cause (elongated eyeball, which is what increases the likelihood of retinal detachment). If you don't change your habits after lasik, chances are you will need glasses again a couple years later as your eyeball further elongates, see: 35% are above 0.5 diopters again just 3 years after lasik https://bjo.bmj.com/content/103/4/565.abstract 58% are above 1 diopter again after 7 to 8 years. https://www.proquest.com/openview/722546068e4b0c9c1d3acba7e3...

I recommend you read more on endmyopia.org to learn about the scientific background and the eye biology behind it. But what I summed up above should easily get you started though and in just a couple of months you should notice improvements in your eyesight (you can test it at home by printing a Snellen eye chart).

Finally going to the eye doctor is no longer frustrating because my eyes are improving instead of getting worse year by year :)

I'm about a decade older than you, was on a computer 12+ hours per day since I was 10.

I started wearing glasses at 16 for 20/40 vision and then switched to contacts at about 25 years old. My vision has remained stable since then except for presbyopia. That is really the only effect of age that I've experienced yet and it is a pain to deal with.

If I don't have glasses on/contacts in I can read something right up against my nose with no problem but obviously have trouble seeing further away.

If I have glasses on/contacts in seeing things close up becomes far more difficult.

So if anyone has a fix for presbyopia, hit me up!

"Taking care" implies preventing long term effects, besides for protective and sun glasses there is not much you can do.

As for preventing fatigue or strain then short breaks are good not only for your eyes but also your back or neck.

What they are describing is presbyopia. It's caused by the hardening of your lens as you age that makes it less able to change shape to focus on close-up things.

No fix that I'm aware of but there are work-arounds:

1) For people that already wear glasses, use bifocal/trifocal/progressive lenses

2) For people that don't wear corrective lenses, use "reading glasses" and constantly put them on and take them off as you switch between looking at close/distant things.

For contact lens wearers, there are some options:

1) Bifocal contact lenses. These gave me a constant headache.

2) Monovision. Essentially one eye tuned to distance and one tuned to close-up. I could not get used to this.

There are some surgery options but really only to give you something like monovision through surgery instead of contacts. Unfortunately there's no fix for the root problem that I am aware of.

Pro tip: with 6 diopters, make damn sure you get your PD correct. Otherwise the headaches you get from the induced prism just won't make it worth it.
