Save 11 Minutes: (if you are in a rush) 3:57 Airflow ( @Jairo Espinel ) -don't sit directly in air conditioning -remove airborne particles (dust, pollen) 5:17 Dryness - If you can't keep your eyes open comfortably for 10 seconds, - use eyedrops or hot compress (moisture) 5:30 (lower) Viewing angle - reading below eye level preserves water by reducing exposed surface area 7:20 Proximity - closer objects --> more work - younger people have an easier time reading up close 8:00 20-20-20 Rule - every 20min = look 20ft away for 20sec 10:10 Optimal Monitor Placement - 20 inches away - 15 degrees below eye level Take care of your eyes as they will only get more difficult with age. Utilize the 20-20-20 rule and optimize your workspace to reduce exposure. If you feel your eyes burning, be sure to use eyedrops or warm compress!

I'm a graphic designer and I've been doing my work digitally for almost 7 years now (plus the fact that I use my PC for personal stuff daily). When I was at graphic design school, I remember we had our screens tilted and lowered, almost touching the top of the desk and our chairs were slightly set higher so we could sit somewhat above the screens. In addition, our professor always told us that our eyes shouldn't be positioned directly at the center of the screen but slightly above it, kind of similar to the way one would comfortably read a book at library or when sitting on a tilted desk that's ideal for drawing. It was really comfortable doing my work with that setting until I actually got a job... I would always adjust my screen and desk to what I found comfortable and easy and my boss would *always* undo everything the next day and scold me about it. He used to tell me that my position was "wrong" so he would set the screen way higher than what it was comfortable to be doing 8 hour work on and also told me to lower my chair because "it's not flattering" to be sitting that high (I never understood what that meant????) so my eyes would get strained from staring up constantly on that screen would turn red. After some time of getting tired with his bs he finally admitted that the reason he kept setting my screen that high and me sitting lower was so he can also look at my screen from his desk without me blocking the view.... not to mention that I already have eye problems like myopia and astigmatism, this would leave me with a sense of dizziness and difficulty focusing throughout the day. I'm glad though that I left that workplace behind me, for this but for a lot of other reasons as well.

Excessive tearing is actually one of the signs and phase of dry eyes . The reason behind it is that our brain will stimulate the lacrimal gland to produce more tears to relieve the dryness from your eye. After that phase of tearing then comes the actual drying of the eyes.

[@ristopoho824]

I'm interested what you think about VR. The screen is projected at virtual infinity, and the objects being looked at are at different directions, so eyes move. Still, blinking less is a thing since games are games, and working in VR is still staring at a screen.

[@ristopoho824]

@NiCat07 Yep it does use distortion to make eyes have to move to focus. Also, it's projected at infinity using lenses. So it's basically like holding an infinitely large phone at infinite distance from your eyes. Well in theory, if the lenses were perfect. Practically they project the image at some distance between hundreds of meters and infinity, depending on the quality of the lense. Static dublicated images do cause a lot of strain since all distances are treated equal, causing the eyes to always point at it directly. That's usually called flat VR, by people who use vorpX or something and the game doesn't support full 3d projection.

[@johnkeepin7527]

Good advice to do with using specific lenses for working at the recommended screen positioning (very similar to my setup at home). I generally prefer to use a pair that are specifically arranged for focussing at roughly that distance with fixed focus. For other things I wear a progressive pair that are good for close up paper reading, intermediate, and long distance. However, they are not optimal for intermediate distance screen work as the horizontal in-focus angle is quite small. The specific reading glasses are better at that working position. It is then possible to scan around the screen without moving one’s head at all - I.e. in a natural fashion, rather than things being out of focus through parts of the progressive lenses, especially in the intermediate zone.

[@bazoo513]

This is one of very few BS-free videos on eye strain when using a computer screen. Perhaps you could also have mentioned "focus hunting", but that was mainly an issue with old CRT monitors.

[@0q2628]

what is focus hunting?

[@bazoo513]

@@0q2628 If you try to focus on a blurry or flickering image, such as on old CRT displays, the "autofocus" mechanism of our visual system continuously shifts accommodation distance, trying (and failing) to find the perfect focus (similar to autofocus in your camera or you have several differently spaced objects in the frame, or try to focus through dirty window or curtains.) This causes fatigue of tiny muscles that squeeze the lens in order to shorten its focal length.

[@knexfan0011]

@@bazoo513 All I could find on the topic just now was people adjusting the focus of a CRT. Would this still apply to non-blurry modern LCD/OLED strobed displays? And does increasing the refresh rate/strobe rate reduce this effect? All modern VR headsets strobe their display(s) to drastically reduce motion blur. Active 3D displays and some gaming monitors also use strobing for that reason.

The screen is not the problem, the behavior surrounding it is. ~~though if you spend enough time in front of screens that your parents are concerned, definitely should go check how much you actually are using it, and if your eyes get enough rest~~.

[@woofiewill]

Thank you for the great info! I would've liked to to see a mention of eye "stretching" exercises. I think this is a thing they do in schools in some Asian countries like Japan. I'd guess that taking periodic short breaks from looking at the screen is one mitigation measure, and that doing a quick eye stretch routine is another. The routine also seems to give a slight boost to alertness and fatigue. This is what I remember of it and occasionally perform: Without moving your head, look all the way to the left, then all the way to the right, briefly pausing at each side and not rushing the movement, and do that X number of times. Then look all the way up and down X times. Then looking all the way to one side, slowly move towards looking at the top of your FOV, always aiming to look at the edge of your FOV, and continue this all the way around in a circle a few times, then repeat in the opposite direction. Another thing I have heard of is that you should try and focus your eyes on something far away from you for 30 seconds every once in a while. Any thoughts on this and what proper implementation of these stretches would be or if you're aware of different routines?

I never attributed the worsening eyesight to dryness. But I'm going to take all of his suggestions and hope that I get some relief. Sometimes my ice burns so much I can't look at the screen cuz it literally feels like I'm looking into the open door of a nuclear reactor. That's when I get up and walk away for 10 or 15 minutes.

I've been a full-time rather obsessed programmer (working many hours per day) for more than 40 years now, and I'm at the age which my eyesight would be fading anyway. Habits I picked up early which have probably helped have been: (1) to make a point to keep blinking fairly often, (2) make sure I have some light on the wall behind my computers lit up, so I'm not staring at a bright screen with a very dark background, (3) occasionally looking up and running my eyes along the intersection of the walls and the ceiling, and (4) Turning off overhead fluorescent lights while working on the computer. That fourth one is almost certainly not as important now as it was back when my computer monitors were CRT's. There are interactions between the flickering of fluorescent lighting and CRT refresh rates which many people will not notice, but which add to the strain on your eyes.

[@agromchung]

No effect at all. Some games can make people feel sick if the motion blur and/or FOV isn't set up correctly, but that's about it.

[@betun130]

I face quite an extreme amount of eye strain but that's probably due to prolonged computer use. I do hesitate to get my eyes tested though. I know I am not exactly 6/6 but I see well enough. I just don't want my eyes to get used to glasses but eventually if the strain remains at that level, I might have to. I have combated it partially by using the techniques you outlined: distance (probably too much distance in my case), viewing angle, using paper printouts, minimal phone use, using paper to write on in case I just am thinking and am not sure about what to write and only being on screen when I really need to type, and using audio as much as I can. My productivity might be better with glasses, they probably will be mild correction, but my morale will suffer a lot and I will face productivity loss from managing a new accessory.

I miss the absence of the monitor to adjust itself according to the background light, constantly adjusting the brightness manually is difficult. The question still remains, if I have a monitor 50 cm from my eyes and if I sit straight, where should the center of my eyes be shown on the monitor? The picture stated 15 degrees downward is ideal?

[@user-tp7je5fb9e]

Thanks for your full and easy explanation! With all my respect, I can't agree with you completely. The one source of pain in the eyes is the way how GPU renders a picture on a screen. I can easily use my laptop from 2018 and my iPhone SE (1 generation), but none from laptops from 2023 (windows laptops and Macs) are not comfortable for me. Now I hurt my eyes badly with a modern laptops testing and I feel so much pain that I can't use my iPhone 13 and a laptop from 2021. But a laptop from 2018 and iPhone SE can be used now 24/7 without any eye strain. How can we explain that? Besides you should consider the PWM technology that is used in most OLED displays now and its harmful affection on focusing muscles. After a week of using MacBook Pro m2, my eyes lost the ability to focus at mid and long-range distances. And this symptom is completely gone after switching to other devices that don't use PWM at all. My eyes completely explored 3 times last year and it's 100% healthy. Your point that the only users are responsible for their computer eye syndrome development, but in reality, the computer manufacturer also does a lot of things that also increase the load on your eyes

@@Raskass-td8lm it's up to him to get sponsors. i'm sure you wouldn't be dumb enough to believe a single youtube video over anything anyway. a truthful video will have other references backing them up on the web. and it's the viewers duty to do research for their own sake, instead of blaming inaccuracies of sponsored contents on a free platform.

Hi! Great video. Any guidelines for how much light in the room? My GF and I have this (friendly) argument about if you can be working on a computer in a dark room of if you should turn the lights on when it starts to get dark. Thanks

Color settings on so called Compfort-View takes out a good portion of blue light which is also a relieve for the retina

My eyes won't stop watering today and suddenly this pops in my feed. I must have said something about it out loud and Google heard me.

Ah, technology...! A world where this is normal.

Great video. Wondering about the point about the eye lens harding over time. Can this be slowed if glasses for computers had lenses that made the eyes correct to “infirmity” focus and not “50cm away” focus? This would likely mess up the focus for looking around the room, but help with not training the eye muscles during computer use

Hey Hakon, thank you for asking. There’s strong evidence to suggest that it’s mostly is the crystalline lens aging. And therefore age is the biggest determinant of a lack of accommodation. And anecdotally I feel the same way.
