Which monitors have the least impact on vision?

Question

Monitors

And also, what should be the brightness, contrast? Are the colors warm?
I use minimum brightness and warm colors + maximum contrast. But during the day it is hard to see. Increase brightness?

Answer 1

“Which monitors have the least impact on vision?” - Off!
“And also, what should be the brightness, contrast? Are the colors warm? - It is determined by eye, brightness and contrast - so that it is clearly visible, but does not hurt the eyes. Color temperature is a matter of habit.
“I use minimum brightness and warm colors + maximum contrast. But during the day it is hard to see. Increase brightness? - You need a balance! Find yourself some comfortable sets. For the day for the evening for the night. And remember that it is strongly recommended to avoid the contrast of lighting. those. there should be light around the monitor.

Answer 2

From personal experience: I try to avoid a white background, I make it as gray as possible.

Answer 3

My purely personal IMHO that the following monitors have a bad effect on the eyes:
1. With uncomfortable brightness and contrast settings.
2. Glare. This is especially true for monitors with a glossy matrix finish.
3. With poor backlight. It happens that even on LCD monitors there is a backlight, the flickering of which is noticeable to the eye. To roughly determine the frequency of the backlight "in the field", there is a method called "pencil test": hold a pencil between outstretched fingers and quickly move it left and right in front of the screen. Due to the stroboscopic effect, depending on the frequency of flicker, the pencil will be visually divided into several. Ideally, it will not separate.
4. At a low brightness setting if the monitor is adjusting it with backlight PWM (most models). In this case, the flickering of the backlight will be more noticeable.
5. Some IPS monitors with a matte matrix and a "crystal effect" (this does not look like color change on TN monitors).
6. With a poor spectrum of backlights, because To improve color reproduction, you have to twist the brightness. It is determined by eye, but not the cheapest monitors usually have normal lamps or even LEDs. "In the field" you can make a white background and use the CD: the fewer dips in the reflected "rainbow", the better the spectrum.

In addition to the above, the refresh rate also greatly affects vision (if it is 60 Hz or less, the eye notices flicker and this can cause headaches), as well as long-term looking at the monitor plane (focusing in one plane) - the eye strains a lot (up to redness and unwillingness to focus until it recovers).
Someone in the comments somewhere on Habré advised the “20/20/20” method (every 20 minutes look 20 meters away for 20 seconds).

Answer 5

The monitor should not glare. In this case, it should be borne in mind that matte ones can also glare, but the glare will be smeared. Ideally, an anti-reflective coating should be applied to the screen. Monitor illumination should match the ambient illumination, and be slightly higher (not bad if auto-adjusted by sensor). The monitor should not flicker. A finger held in front of a monitor should leave a smooth trail, not a storyboard. The monitor should be in the focus of vision, the picture should be clear without “pointing”. Color reproduction should be closer to natural warm (no cyanotic TN). The resolution must be high enough to not see pixels when sub-pixel text anti-aliasing is enabled.
And even though this is no longer on the topic of vision, but most of all I hate squeaky monitors. If something is beeping at a high frequency in the monitor, even in the next one, then by the end of the day you can go crazy.

Try your monitor at www.lagom.nl/lcd-test/inversion.php Poor
inversion logic may still have subtle effects. The truth is rather not on sight, but on the psyche.
Well, don't forget www.lagom.nl/lcd-test/sharpness.php , it's also a very important part.

Answer 7

Flickering backlight yes, it's very annoying. Also, a strong unevenness of colors depending on the angle of view leads to the effect of a metallic sheen - the eyes are also overstrained from this.
There is also a nuance - a person has a horizontal resolution of vision greater than vertical - therefore, the horizontal arrangement of subpixels in a row is more preferable for smoothing - the horizontal resolution of fonts increases.
But monitors are monitors, and you should not forget about other factors:
- External lighting. The brightness environment should be close to the brightness of the monitor. Working in a dark room behind any of the finest monitors will effectively set your eyes in no time.
— Fonts. Small fonts are just as effective on the eyes. The lack of anti-aliasing leads to an increase in the high-frequency component (due to sharp pixel boundaries) - also an additional burden. Poorly smoothing also leads to unnecessary eye strain.
— Distance and location of the monitor. The high-mounted monitor does not allow the eyes to relax in the normal position of the neck. Too close a monitor requires increased accommodation of the lens, which can subsequently lead to fixation of this state and the inability to focus to infinity (myopia).

Answer 8

Recently bought a good monitor. Benq EW2430 - uniform illumination, good colors, no glare, not the most convenient, but a normal menu. It has a VA matrix (better than TN in everything except response time, better than IPS in a nice black color).
So that your eyes do not get tired, you need to work with the light on so that the brightness of the monitor is not much higher than the brightness of the wall against which it stands. Well, you have to sit far away, and the fonts are larger if you wish.
During the day, in sunlight, a neutral color temperature is well suited, and in the evening, a warm one.
Of the minuses of this monitor - there is no height adjustment, but this is easily solved with an additional stand.

Answer 9

Is there a way to adjust the monitor if you don't understand brightness/contrast/temperature?
Is it possible to find settings from another user of the same monitor model (in similar lighting conditions) and drive them in?

Answer 10

Are there any monitors that automatically adjust the brightness of the backlight / other parameters to the ambient light?

Answer 11

I will not add anything new, let it be a plus to the above.
I adjust the brightness so that the monitor doesn't appear to "glow" relative to the surrounding area in focus.
In the absence of sufficient lighting of the entire room, I always turn on the table lamp.
And it's natural to take breaks, it's great if you can look out the window into the distance.
Do not play more than 20-30 minutes a week :)

Answer 12

So that your eyes do not hurt:
1. The most important thing is to reduce the brightness. The higher the brightness, the higher the strain on the eyes. It is better to set the minimum brightness at which the text is well read.
2. Increase gamma. When increasing the gamma, the image becomes like on a cheap monitor, but such an image is much more pleasant to look at + as a very big bonus, dark shades become much easier to distinguish (in dark photos, pictures, videos, games, etc.).
If, on the contrary, to reduce the gamma, the image will become more beautiful, but less natural, and also a low gamma will increase eye strain, so I advise increasing the gamma. Although it depends on the monitor. On my current monitor, gamma 1.2 is the same as on the old 1.0. Very big difference.
3. Reduce the contrast so that there is no such thing as too white white.
4. Many monitors flicker at low brightness. Do the pencil test and also the camera test. If your monitor does not pass the test, then it is better to buy another one - now Flicker-Free monitors cost the same as flickering monitors, and the Yandex Market even has a Flicker-Free filter.
5. Reduce the blue color to make the image MUCH nicer. Please note that when reducing the blue, you must also reduce the green color. The decrease in green should be 3–3.5 times less than the decrease in blue. For example, if you reduce blue by 6%, then green should be reduced by 1.85%.
I advise all people to reduce blue by at least 3% (and therefore green by 0.92%). The image will become more beautiful at times. Also, thanks to the improvement of colors, you can further reduce the brightness of the monitor, and this will reduce eye strain.
However, you shouldn't get too carried away. Excessive reduction of blue is fraught with the following consequences:
1) White color will become too "burning out". This will increase eye strain.
2) The image will become less natural.
3) Even if at some point in time it seems that the image looks better, in fact it looks worse.
For these reasons, blue reduction should not exceed 12%. This is the limit. As a result, blue should be reduced by a number from 3 to 12%, but I recommend from 6 to 9%.
PS. Don't get carried away with reducing green - the green reduction factor should not be less than 3, otherwise it will lead to burnt white.
