I understand the hesitation, but that's the thing about this: It's even simpler than cataract surgery (where they actually _replace_ your own lenses instead of just flopping one in front of it), which is very very common, and very very safe. See: https://en.wikipedia.org/wiki/History_of_cataract_surgery IIRC the chance of complications for Lasik is about 10x that of the one for intraocular lens implantation. The natu…

I would still never bifocals or at least reading glasses. Once you reach around 45 everyone day. Lasix probably makes you need them sooner (but we are talking at most a couple years, not very significant) I get my glasses in ANSI rated safety glasses so wearing glasses all the time doubles as protection from all the things that could get in my eyes. This is useful if you have hobbies where that is a worry, though for…

What are the rest of the words? Or the auto'correct'-corrections?

You would still wear* and after 45 everyone does* perhaps?

Taking pain meds daily for life doesn't seem like a good plan. Maybe try e-ink? There are e-ink monitors on the market if that works, if the problem's the light. You can also try software like Redshift[1] for regular monitors. If it's your neck, at least put some books under your monitor stand, if you're not able to get better monitor mounts. Or lower your chair. You should be looking straight ahead for your monitor,…

>Taking pain meds daily for life doesn't seem like a good plan. Definitely not a good plan, especially Ibuprofen. My mother took Ibuprofen for years to manage her arthritis and that absolutely wrecked her kidneys. Not to mention Ibuprofen can also cause internal bleeding. It's a quick short term fix but not a good long term solution.

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.

My first pair of glasses were glass and even though I suspect the prescription was not correct I never had eye strain and headaches but they shattered in less than a month and then I moved to polycarbonate...it took me a year to find out that the polycarbonate glasses were the ones causing me discomfort and strain. Since then I only get actual glass.

Tons of responses so I don't know if you'll read this but a few things:

Post-concussion syndrome (and screens)

After getting a concussion, I had to change my screens in a big way. Many people have heard of sensitivity to PWM and low frequency PWM in particular. The alternative is DC dimming, and it helps tremendously. Additionally, higher refresh rates seem to help. At least 120 Hz but preferably 144, 165 or higher. My phone has some complicated PWM / DC dimming settings[0] - possibly 120 / 360 Hz[1]. My laptop is 165 Hz and does not appear to use PWM[2]. My desktop screens are 144 Hz and have DC dimming.

I'm going through the hassle of getting a physician to sign off on an ADA request to get my current employer to allow me to use better screens at work, as they provided a laptop with a horrible 60 Hz screen, and two crappy 60 Hz monitors. Fortunately I'm only in the office twice a week.

Glasses

Last year, I got brand new glasses with the prescription determined by the optometrist. However, it took three tries of adjusting things like pupil measurements and the "base curve" or index of the glasses before I started to get used to them. Up until then, I felt very tired and brain foggy while wearing them. With the third revision and a week of adjustment, I finally started to settle in. It takes a really good eye doctor to figure out these kinds of issues, and be willing to swap out lenses for you.

This sounds like an interesting area of research! I built LookAway[1], a break reminder app for Mac that helps reduce screen fatigue by nudging users to take short breaks. A lot of users report feeling less eye strain and headaches after using it regularly. Might be useful data for your research!

I’ve found the best solution to eye strain is just turning down my screen brightness. It’s solved all my problems, and I can stare at a screen as long as I need to now

Yes, this is a huge issue. The screen brightness should be close to the ambient brightness.

I test by looking around randomly a bit, keeping my screen in my peripheral vision. If it “pops” brightly in my peripheral vision, I know it’s too bright.

Or I adjust the other way; if I’m planning use a screen for a while in a dark room, I’ll turn on some lights to bring up the ambient level a bit.

I am having so many issues with my vision. I don't have a very high prescription(+1.5 on left and +1.25 on my right) but I consulted 3 eye doctors and optometrists last year. I still don't think my prescription is correct as I get headaches and my eyes get tired after few hours. I don't know if there is any better solution around.

Have you adjusted the lighting around your monitor/office? This seems to have a big impact on my eye strain.

a brighter room with light screen (not dark mode) causes smaller pupils and thus better focus.
