This is for all of us. How do you deal with eye strain as well as eye fatigue?
Do you do some special eye yoga or some eye exercise? Do you use some special glasses with some extra coating or filters? What do you typically do? What has worked and what has not worked?
I have Fokus QT widget which makes me take a break every 30-40 minutes. In that break I try to focus something which is alteast 100 meters away and outside of the building I am working in.
I just try to pay attention to how I am feeling and when needed take a break and do something else like going for a walk, spending some time with the cat or doing a bit of housework.
A habit I cultivated when I started working for $$$ was to keep drinking water. It’ll just force you to get up from your chair and head to the 
every 45 minutes or so. Plus, helps keep your water intake in the right range (don’t overdo water though! I live near the equator so I naturally need more water)
Apart from that, its mostly completing my required sleep hours, having a good diet and good posture. I’m likely younger compared to others on the thread so my experiences may be different 
Great question @Archie1 
@smokey and @flyingcakes ideas are 
Particularly the getting out of the house and looking at things not-near. Look at some 
, 
and 
, and ideally not the emoji kind 
I wanted to add though, that how you set up your work space is important too. One should be mindful of not backing their screen onto bright windows or blinds, where their eyes are straining against bright outside light while working.
The other is reducing glare, so even having bright daylight behind you (reflecting on the screen) is not ideal.
Then, in the darker hours of the day, one needs to be balance the screens with the room light. If it’s a dark room for example and the monitors are the only thing emitting significant light, that’s eye-strain territory again, so there needs to be a sufficient degree of light in the room to help balance.
I will often turn on the night-mode too after hours, to redden the screen, depending on the work I’m doing.
Just wait. It won’t be so long before you don’t have to drink anything at all but still have to use the the every 45 minutes or so… 
All good advice above. But, just as sometimes you don’t know what you don’t know, sometimes you don’t know how well you might be able to see.
I’ve reached the stage where the environmental and behavioral solutions were no longer sufficient. I’ve gone surgical. Cataract surgery at a younger age than usual was a very big help. And it meant I no longer had to wear glasses except at the desk.
But in about one-third of the cases (such as mine) over time a cloudy membrane grows over the implanted lenses. They blast that off with freakin’ lasers.
Which added to the other junk floating around inside my eyes–mainly from gel detachments, which are different from (but can lead to) retinal detachments.
And I still had issues with cloudiness (and resulting eyestrain and fatigue) that the docs said were just old age and I should live with it. I called bull manure.
I’m still in the recovery period after two vitrectomy surgeries. They suck out all the juice from inside the eye and replace it. Holy smokes! The detail and clarity I see was like a rebirth. The whole world is new again. I can see better than I ever have before, and better than almost everyone I know–including people decades younger.
The moral of the story is that if you have eye strain/fatigue, blurriness and cloudiness that glasses/contacts, environmental and behavioral changes don’t fix, press your docs to explore surgical options.
I have just 3 tips.
Use a colour temperature filter, whenever possible. I know that redshift, gammastep, wlsunset and KDE Plasma allow to use colour temperature filter even by daytime – in this case, find your comfortable values and stick to them.
For me, those would be around 4500-5000K in the day and 1900-2500K in the night, depending on the screen.
Do regular breaks. If you’re not doing anything important, 45 min screentime and 15 min break would be enough. If you are doing tasks requiring more focus, use Pomodoro technique.
If you’re using Xfce, there was a panel applet which forced you to do breaks… I don’t remember, however, how it was called since I don’t use Xfce anymore.
Don’t go hard on daily screentime. I, personally, on the working day when I work 8 hours, try to use my personal rig for max 1 hour… and sometimes I succeed 
I also try to spend weekends more offline. Quite honestly, I feel more healthy reading a book, taking a walk or going to the cinema than browsing Reddit in search for a perfect Linux rice.
Time Out 
For me, using dark mode everywhere helps a lot. Of course, everyone has different eyes so it is probably different for everyone.
That being said, if you are taking breaks and still having eye strain issues, I would probably chat with an eye doctor about it. They will be able to look at your specific eyes and let you know what is best for you.
redshift, walk around neighborhood (get outside)
You have had 3 eye surgeries till now? Which age bracket do you fall in, 20-30s? 31-40s? 41-50s or 50s and higher
Were vitrectomy surgeries painful? Is the post the surgery painful? How much did it cost you? Were they paid by medicaid or insurance ?
@erne.d.98 thanks for your inputs they were helpfull.
I am on KDE Plasma and yes KDE settings have the option of DayShift. I am going to put this in KDE Tips and tricks section too.
Are there any eye exercises that help? Like looking at the distance for 30 secs? Or cupping your palms and covering the eyes such that complete darkness is created while the eyes are kept open. Or some other
Or are these eye exercises hokum and are based on the placebo effect?
I’m a sample size of 1 in a lower age bracket, so don’t take me too seriously in matters relating to long term health, but I certainly can feel a difference in how fatigued I feel if I’m not taking breaks to look in a distance.
(((I haven’t done the hand-cupping thing regularly ever, so can’t comment on that, but I’m sure it also relaxes the ciliary muscles. (don’t quote me on this; I dropped biology back in high school itself))))
Now to be very honest, I don’t actually sit in my chair and stare at a far distance. I instead prefer going out on a walk and then I’m anyways looking at things that are at a distance. Thankfully my workplace allows me to do that at my whims and fancies.
I would say, you will be able to feel if a certain ‘exercise’ makes you feel less fatigued if you do it regularly. Again, of course, ensure your health otherwise is under control - sleep and diet being the most basic things. If covering your eyes helps you relax your eyes, then its fine 
None of this is medical advice
I’m four weeks away from turning 69. The age. Minds out of the gutter!
Two surgeries and the laser thing. It was an infrared laser so outside the visual spectrum. Done while in the same sort of stand they use to check your eyes. Had to look at a target while they zapped. Took longer for dialation than it did for the laser.
Cataract surgery in the usual way. Nothing more than drops (antibiotic and steroid) afterwards. That was done at 61 or 2–just prior to the pandemonium. It’s a choice to do it while you’re awake. I chose general anesthesia. Didn’t really want to watch, you know? I had a cow-orker who’d had hers done at age 55. She encouraged me to do it early. I’m glad she did. I had significant yellowing in the original-equipment lenses. You don’t know what you don’t know. You know?
Three or four years later, the laser. It helped, but things still weren’t right. Took a few years for them to listen to me and schedule the vitrectomies.
Recovery from the vitrectomy was similar with the drops, but also there are stitches in either side of the sclera (the white of the eye). Wore a patch for 24 hours, and it took a few days for the vision to clear up. (Looked like I’d been swimming too long in an over-chlorinated pool.) But when it cleared, wow! For a week or so the sclera was red instead of white. There was a zombie looking back at me in the mirror! There was no pain though. (And no appetite for brains.) Just the same sort of annoyance when blinking as when an eyelash gets stuck in there until the stitches dissolved.
Everything was covered by insurance. (Living in the US–Medicaid for the cataracts, MediCare for the vitrectomies). I don’t remember the co-pay for the cataracts, but it was $450 for each eye on the vitrectomies, which includes the follow-up appointments. The last of which is next Wednesday.
As background, I wore Coke-bottle glasses since starting school (-7.75 for those keeping score at home.) Problems became more and more noticable as I moved to bi-focals and tri-focals. It was a while before I could afford progressive lenses. But there was always someting that made it hard to work without eyestrain. Tried everything suggested so far in this thread. Some helped a little. Others not.
