Whenever I see a mountain lately, I run to the top of it so I can sing the praises of my 31.5-inch Dell UP3218K 7680 x 4320 8K computer monitor.

I'm a software engineer by trade, so I am looking at code all day long, plus lots of web searching and other text-heavy computer use.

I thought the LG UltraFine 5K and Apple XDR Pro Display were "good enough for my eyes" since I couldn't see the pixels.

Compared to the XDR (same size) the text on the 8K screen is WAY WAY sharper. Even though I thought the 218ppi XDR (basically same as 27" 5K monitor) was crisp before I saw the 280ppi Dell, I immediately realized it totally wasn't.

I can feel the eye strain difference, too. The lower res monitor is just fuzzy. I can't see the pixels individually, but when I slide my chair from the Linux box with the 8K to my Mac with the lower-PPI 5K display (sold the pricy XDR immediately after seeing the 8K panel next to it), I can see the fuzziness at the edges of text.

So I am kicking myself for not getting this much earlier. The Dell is ancient, came out years ago and requires 2 DisplayPort cables.

I am not an ophthalmologist so I can't speak to what this will mean for my long-term eye health, but I can say that my eyes are significantly less tired at the end of the day, and I never have to use the computer glasses I bought a couple years ago (the kind that are like reading glasses but for a little farther distance). I was using those a lot before, since my middle-aged eyes are indeed deteriorating.

BTW, for a few weeks I had the 8K Dell and the 6K Apple displays side by side. They are the same physical size, and the text was just about exactly the same size. Most of the people I asked to come look at them agreed the 8K display "looked better" or "looked sharper".

There is also the factor of Linux vs Mac font rendering. I am using Pop OS with 200% UI scaling on the Linux. I kinda wanted to compare them side by side in macOS, but I don't have any Macs that can drive the weird 2-cable Dell. So that could also be part of the difference, but I think it is basically just that 280ppi is way, way better than 208ppi.

I've been eating pineapple in the last few weeks to see if it gets rid of my eye floaters: https://www.benjamineye.com/blog/eye-floaters/ > Three months later, out of 120 subjects in the first group (1 slice), only 35 still experienced eye floaters, an improvement of 70.8%. In the second group, only 19 participants still saw floaters, an improvement of 72.8% > How does it work? Scientists believe that enzymes in the…

Does it work with only fresh, canned, dried or all forms of pineapple? I'm pretty eager to reduce my eye floaters.

As someone who suffers from recurrent corneal erosion (scratches on cornea, that are painful as hell) I incorporated a set of steps to manage this condition. 1. Daily eyelid hygiene - using special wipes to get the leftover from your eyelashes, to unblock Meibomian glands. It can dramatically improve how your eye is moistened. People who suffer from dry eye syndrome should at least try it. 2. Using eye drops daily -…

I had phototherapeutic keratectomy in both eyes (about a year apart) that basically cured my recurrent corneal erosion. I sleep in extended wear contact lenses most nights which help protect the cornea. I also have quite severe myopia so this is also convenient for when I wake up, using the toilet, wanting to know the time, reading the message that just arrived, etc. Then I just need some eye drops in the morning. I…

I had phototherapeutic keratectomy which indeed helped me stabilize the situation, but didn't clear the symptoms 100%. I still have occasional erosions, which are much less severe and last way shorter than previous ones (minutes and not days). But I'm not sure if it is because of PTK itself or because of extra care that I give to my eyes daily.

I had similar problems. Eye drops in my case didn't help, it mostly was caused due to producing to little tears at night when I sleep, I can't put eye drops in when I sleep. But there where some things which did help: - eating/drinking healthy, while unclear it seems my tear under production was partially linked to a unhealthy diet - eye hygiene helped a bit not much - Making sure air humidity is at a good level duri…

The last one is indeed the golden one. When I feel that my eyes are sealed or I feel a lot of friction I use my fingers to help open my eyes. After that I put some eye drops in.

What is very interesting that there is a certain set of actions that you can take and the ones that helped you, didn't help me (diet - I've been eating healthy for a long time, air humidity - we use air humidifier for a long time too), but the ones that were great for me (eye hygiene) didn't help you.

What type of wipes?

I live in Poland so there are different brands of these lid wipes, but "Systane lid wipes" look about right.

Earlier quoted context omitted.

You're welcome! I get that feeling too, makes me uneasy. Best of luck on your eyesight improvement journey!

Where do you buy "differential" lenses? Do you just get a lower prescription from your optometrist?

I get them from AliExpress, because it's super cheap there. Some sellers only offer very standard prescriptions (same diopters on both eyes, standard pupillary distance, no astigmatism correction). Others also offer to create glasses with custom prescriptions, just like you'd get the glasses from the optician.

Zenni Optical also offers custom prescriptions, but is more expensive (likely still a lot cheaper than your local optician).

But you can totally also get glasses with a lower prescription from your regular optician, but as you will relatively frequently need new glasses, that can get expensive (at least here in Germany it would, and I heard in the USA glasses cost up to $1000).

I try the 20/20/20 thing - every 20 mins, spends 20 seconds looking at something 20ft+ away. I wear sun glasses outside when it is even moderate bright. I take lutein, "the eye vitamin." I keep pretty far from my monitor and its elevation keeps my head in a neutral position. I also have semi-regular exams at a retina specialist to monitor some thinning.

Do you recommend a particular lutein supplement, or do you just rely on lutein in foods (e.g., leafy greens, fruit)? In your experience, what have been the benefits of lutein?

I take Macushield (UK brand) and it got lutein (10 mg), zeaxanthin (2 mg) and meso-zeaxanthin (10 mg).

It was shown on a BBC program to help. I tried it and it changed things drastically for me. I used to have my TV very close to my couch because I was struggling when watching movies or gaming. It also made my sight better at night.

Obviously this is my personal opinion only.

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, boo…

Understanding exactly how much of modern health systems/guidelines are based off of capitalism incentivized research which then get some form of regulatory stamps of approval is appalling. Not griping about capitalism, I think its the best thing out there for the economy, its just that we haven't figured out a way to prevent it from creating authoritative science backed research that somehow always promotes the fundi…

That's exactly my thoughts. This is crazy. It is basically the wrong alignment of incentives. Wonder how we are going to protect ourselves from it right now and fix the system.

When I told my optometrist that I was a software developer he took me into this office and showed me his computer setup. Basically, he was a huge proponent of using massive TV screens in place of smaller computer monitors as it was so much easier on the eye. I'm typing this on my machine connected to a 55" 4k TV that's about 33" away from my face. Given how inexpensive 4k TVs are compared to monitors and how well the…

I was under the assumption that bigger the monitor more the light and more strain on the eye. Am I thinking wrong ?
