The solution for me to eliminate headaches when working at computer screens was getting an extra set of intermediate distance glasses specifically for computer work. The "computer screen distance" of 3 ft is in between book-reading distance of 1 feet and driving distance 20'+ feet. I also avoid progressive lenses or high-index lenses for computer work. I commented about how arrived at this solution previously: https:…

Same - the funny thing is that right now my 3-foot prescription is zero (plus a bunch of astigmatic correction). Apparently my mortal frame has accepted its purpose.

One solution I haven't seen mentioned is trifocals. Progressive lenses used to be sold against bifocals and trifocals by saying "no lines" but there are some advantages to the old school designs. In particular, progressive designs tend to end up with an hourglass-shaped field of view[^1] in which the horizontal field of view at mid-distance can be so narrow you can't see your whole monitor screen without pivoting you…

I've recently started wearing progressives, previously I was constantly putting on and taking off reading glasses (I'm far sighted). My usable field of view is more funnel shaped than hourglass shaped. At the bottom I can barely get both eyes to focus on something up close at the same time, it's only really wide at the top (wear I don't need much correction, just for slight astigmatism). It's better all around than no glasses or keeping my readers on all the time, but it's not as nice as I had hoped.

Since it hasn't been mentioned yet, I must add this: when we work and focus, especially when using digital screens, we tend to blink a lot less frequently. If tear composition is not good or there are other exacerbating factors (e.g. an AC with high flow), the break-up of the tear film can easily lead to eyestrain and even blurry vision. In such situations, preservative-free artificial tear drops 3-5x a day can lead…

just a +1 here. I thought I had serious eye fatigue and focus problems. screwed around with various prescriptions. changed optometrists twice. went to an opthamoloist, and she just said..wow, yours eyes are really dry, use these drops. helped immensely

I use a 60" TV and get farther from it. Stopped needing glasses.

I'm in my 50s and about 3 diopters farsighted. I had trouble getting a good prescription for screen glasses. My optometrist insisted that +1.25 was the right correction for desktop screens, but it gave me eye strain. I like my screen a little closer, or else my corneas are extra-stiff. Anyway, I tried a few versions and found that +1.75 was better for my desk setup. Tip: Zenni.com lets you order pairs with custom cor…

Up to +3 can easily be tried on and bought at a drugstore. I’m severely myopic (-11), though that is corrected completely by contacts. Presbyopia, alas, hits us all.

Well, I need a substantial astigmatism correction too. I've tried combining both -- my prescription distance glasses with drug-store reading glasses over top -- but it's wobbly and limits my field of view to less than a whole big monitor.

Earlier quoted context omitted.

If it's posture related, here's more free advise: try sitting on stools rather than on chairs with a back, and sit up straight and keep your arms actively powered while typing (not laying on a surface). Also, when you need to think for a minute get up and walk around.

A stool without a back would be very uncomfortable, but I do have ergonomic chairs (Herman Miller Aeron) which should do a decent job from what I understand. The rest I'll consider though, thanks.

The point of sitting on a stool is that you have to use your core strength to sit up straight, and using that core strength reduces all sorts of pain in back and neck.

I didn't start doing that (sitting on stools) till I had been meditating for a long time, so it wasn't that different than sitting on the floor in half lotus position, which I had extensive practice doing.

I've been doing it for >10 years now; I will confess that when I have a meeting in a meeting room with proper chairs, I do really enjoy the chair back. It's all about using your body in a variety of ways.

There's an interesting new treatment, Miebo in the US, Evotears in other areas. It's basically a tear film reinforcer (pure PFAS!)

https://en.wikipedia.org/wiki/Perfluorohexyloctane

It's really eerie how moist it makes your eyes feel after even a few uses. I have definite reservations about instilling megadoses of PFAS directly into my eyes but there's no doubt that it is amazingly effective.

Before I got my first pair of progressives lenses I saw a lot of conflicting anecdotal accounts. After doing research, the conclusion I came to was simple: I got the very best progressive lens that Lens Crafters sells because the best lens has a much larger intermediate “corridor” size than less expensive progressive lenses. I have had zero issues with my progressive lenses. I forget I even “have” progressive lenses at all!

By asking to talk to only those who have problems, you could be self selecting for a population who may not help you actually solve your problem, even if they mean well.

This is just my experience of course. When I did my initial research, I asked a question on Blind about progressive lenses. Lots of people said they have progressive lenses and they have zero problems.

If I was forced to guess, I would say that some (or maybe even all) of these folks who start talking about the computer glasses……it makes me wonder if they simply under-bought their lenses. Yes glasses are expensive. Getting a better lens will cost more. Yes yes, the Luxotica this and that. I don’t care about any of that crap. All I care about is getting the best lens possible and so should you!

Do what I mean!
