I got glasses that were focused at approximately the distance my monitor is from my face (~1 arm length).

I'm near sighted and the monitor starts getting blurry at just the right distance. I have glasses for nearsightedness that are focused very far out (the common case). Wearing them for constant work at arms length really tired my eyes out. So, I'd frequently work without my glasses, but hunch forward a little to make seeing things easier.

With glasses dedicated for computer work, I can read everything I need to, my body can stay in the position it should be, and my eyes don't get nearly as tired.

As a side benefit, the glasses help me focus in other areas of my life. I frequently wear them while cooking, and it helps me do one thing at time, as other stuff is blurry.

Seconding the recommendation for getting "task glasses". It is probably the single most impactful change one can make.

I ordered a pair (via Zenni, just some regular polycarbonate lenses) that are at just the right optical power such that if I fully relax my eyes, objects 1 metre away are in focus. When my monitor is that far away, it's at optical infinity and very comfortable to look at for long stretches. It's a very noticeable difference: on the occasions that I forgot to put the task glasses on and wear my normal glasses by mistake, my eyes almost always end up feeling sore after a few hours.

I'm tempted to get another pair at 50 cm for laptop and phone use.

How do you calculate this? Is it based on your previous prescription somehow, or does it require another optometrist appointment?

Just add diopters to the SPH (sphere) portion of your prescription, there is a formula 1/diopters to get your desired focal plane: +1 for 1 meter away, +1.25 for 0.8 meters, etc

I started using reading glasses (non prescription) a while ago when I was getting a lot of migraines. My vision was fine but I had difficulty switching focal lengths. The glasses just made it a little easier and my eyes felt a lot better at the end of the day. Migraines reduced too.

The other simple one is to just increase font size when you’re feeling strain. I’ll often change my font size when I’m in poorly lit conditions or if it’s the end of a long day.

I don't really have any distance issues seeing. I'm technically slightly farsighted.

What I do have is an astigmatism. Getting glasses (it was free with my work insurance) made a huge difference in my ability to stare at the screen all day.

If you find yourself _ever_ squinting at the screen, go get glasses. Or if you feel your eyes get "dry". They're both likely symptoms of an astigmatism.

I can use my computer and phone without glasses fine, but after ~4 hours I start to feel fatigue. And text is _slightly_ crisper with glasses on.

I have astigmatism and nearsightedness

And I did what burkemw3 did: Astigmatism-correcting glasses only.

But it was very difficult. I went to an optician to buy them, and they told me, I would not need them, so they won't sell them to me. When I am nearsighted, all my glasses should correct nearsightedness fully.

And to make it worse, they were not able to measure my astigmatism. The first one I went to measured 1.5 D cylinder and gave me such glasses, but that was a little blurry, so I went to several others and measured them and then said you have 20/20 vision, so everything is perfect. I finally found one who measured my eyes from scratch without taking the value of the old glasses and then he found 2.75 D cylinder, leading to a 30% better vision than 20/20.

However, some of the opticians had wavefront eye laser scanner. That is a really advanced method to measure directly how the eye affects lightwaves rather than trying different lenses. The devices measured that I actually need a 3.6D cylinder. But the opticians always discarded that measurement, because it was not possible that I had 20/20 vision if my glasses are two diopter too weak.

Anyways, since they did not sell me computer glasses, I bought them online, and just put zero for spherical value of the prescription. Although there seems to be something wrong, since I am always seeing sharper on one eye than the other. I also tried buying a stronger cylinder online to check it out, but that was not possible since the online sites did not sell any cylinder stronger than three diopter.
