I'm nearsighted with no astigmatism, so I have a simple -2/-2 prescription (if I remember correctly). I sit at a screen 8-16 hours a day. I get strong headaches every single day, for which I keep a supply of ibuprofen at work and home. 400mg a day is generally plenty. I do not wear my glasses while at the screen, as it's close enough that I don't have any issues. I suspect my headaches are neck muscle related, not ey…

Are you using a laptop (looking downwards) or are you using a proper screen setup?

This is a very important point. Staring down on a laptop screen strains neck muscles but it feels like you are getting headaches from your eyes.

Make sure your posture is correct when sitting in front of a screen before attempting anything else.

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:…

That makes a lot of sense. I've heard of people using computer-specific prescriptions, but I never really thought about how much difference that intermediate distance can make. I wonder how many cases of "mystery" eye strain are just from using the wrong focal range all day

Hope you find some relief soon...

Yes, I'm very nearsighted. I've worn progressive lenses for years but they continue to drive me crazy. I can see fine with them, but my eyes easily get fatigued and I have to take long breaks to get them to calm down. Over the summer I added a pair of progressive occupational lenses (not reading glasses). They are focused arms length in front of me. This has been a complete game changer. I can now see my monitor cris…

Do you find yourself swapping glasses a lot throughout the day, or do you mostly stick with the occupational ones when working?

> I also avoid […] high-index lenses for computer work. Yes! You're the first to mention this. It's not refractive index itself that's the problem, it's dispersion (roughly, the degree to which refractive index varies across the visual spectrum, described by ‘Abbe number’). We've all seen pictures of a prism splitting a beam of white light into a rainbow — for visual purposes, the less split the better. Higher-index…

It's not just about the material. It's also about how the lens is made. For me, choosing "freeform" over "aspheric" was night and day.

Have you visited ophthalmologist? I’d start there. Your situation sounds too specific for good advice on HN…

I have a strange vision problem these days. I dont feel that my eye power is constant, rather, it feels like a range

Some days i can see clearly through my prescription lenses while on others i dont. I also have gone for eye power checkups on different days and indeed my prescription is different.

On my last visit i also got my axial length checked. Will do the same on my next visit and see wtf is going on in there

Ive got all sort of test btw Fundus examination Corneal thickness Corneal shape Topography

So far no one knows whats happening

So I've just got a pretty major astigmatism in one eye, very minor in the other, without any other distortions. I went thirty years without corrective lenses and I think this kind of caused and reinforced my lazy eye.

With simple prescription lenses for the astigmatism my eyes are much better at looking at the same place, but at the end a long day I have a ton of trouble getting them to agree on where to look and often end up just closing my right eye.

> especially ibuprofen [...] wrecked her kidneys As opposed to what? It's all metabolised by something, choose what you wreck. Take paracetamol routinely instead and you'll wreck your liver instead.

IMO neither is good for chronic pain management. Ibuprofen reduces blood flow to the kidneys which causes (chronically) cell death. Weirdly paracetamol is bad for the liver as you mention… unless you already have a bad liver, in which case it’s somehow the recommended pain medicine? (For responses I’ve unfortunately forgotten). It’s much harder to address the root issue (speaking as someone who’s taken their fair sha…

Certainly didn't mean to suggest they are, especially not without professional medical advice. (Not just to check the dose or have a different one prescribed, but for a PPI to protect stomach lining from taking a lot of ibuprofen for example.) The non-prescription doses on the packaging are suitable short-term, for a one-off headache or to manage a fever, but continued use (a bad injury meaning your taking it several days even) should be with advice, that might differ.
