How to adjust the monitor so that working with the computer does not affect the user's vision?

In our time it is difficult to imagine a house in which there is no computer. This technique has become a reliable assistant in the work, study, search and processing of information and even in the simplest household affairs. An integral part of any PC is a thing like a monitor. It depends on it, how tired the user will be with the eye, whether there will be a headache after a long sitting on the Internet and whether a person can work normally for several hours a day. This article will tell you how to adjust the monitor as correctly as possible, so that it does not harm your health, and spend time with the PC was as comfortable as possible.

First, let's figure out why your eyes get tired when you work at the computer. When sitting for a long time in front of the monitor, the load increases on many groups of muscles - additional muscles receive the muscles of the hands, neck, back. But most of all, the eye muscles get tired. This is due to the fact that the person sitting in front of the computer needs a certain concentration of attention, as well as changing the way and speed of reading.

In addition, the technical features of many monitors lead to the fact that the computer user starts blinking three times less often than usual. Because of this, the protective film of the eye dries much faster, and the cornea is not adequately supplied with moisture. As a result, there is a decrease in visual acuity (in some cases, even may develop false myopia), there is a feeling of dryness and burning in the eyes, pain during eye movement, and pain in the eye and forehead. Now let's look at how to adjust the monitor so that during work it is possible to minimize the load on the eye muscles and to avoid the appearance of these unpleasant symptoms.

One of the main factors that affect the fatigue of the eyes when working at the computer are the contrast and brightness indicators of the display. To understand how to adjust the computer monitor in the best way, you need to know a few nuances of how our eye reacts to brightness. To minimize the load for the eyes, it is necessary to adjust this parameter so that the brightness of the monitor corresponds to the brightness in the room. If the room is very light, you need to "twist" this parameter on the monitor, and if it's pretty dull (or if you like to sit at the computer at night), then on the contrary, lower it. How to properly adjust the monitor, the body can tell and itself - in bright lighting in the room, the image on the monitor appears insufficiently saturated, and in moderate light it will seem too bright. It is necessary to experiment only a little, and it will be possible to choose the optimum variant of the level of brightness.

But as the technology does not stand still, the leading manufacturers of displays have saved us from constantly adjusting the brightness by releasing Smart-monitors. Displays of these devices are adjusted for ambient lighting automatically. How to set up the monitor if it does not have the Smart function? The easiest way is to open a blank sheet in the MS Word program, and compare its "whiteness" with the lighting around the monitor. If this sheet will dazzle and resemble a lamp, then the brightness should be slightly reduced. If it appears darker than its environment, then you need to slightly increase this parameter.

Do not forget about the correct placement of the monitor. It should be located slightly below eye level (forming an angle of about 10 degrees). Behind your workplace there should not be direct light sources capable of creating glare on the display.

And now, when you know how to adjust the monitor correctly, let me remind you one more simple truth that helps to save eyes while working at the computer. Adult person per day should not be spent in front of the monitor for more than six hours. For children and the elderly, this time should not exceed two hours. Do not forget about it, and your vision will forever remain in the best shape!
