Nowadays 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 most simple household tasks. An integral part of any PC is such a thing as a monitor. It depends on him how much the user's eyes will get tired, whether there will be a headache after a long time surfing the Internet and whether a person can work normally for several hours a day. This article will tell you how to configure the monitor as correctly as possible so that it does not harm your health, and spend time on your PC as comfortably as possible.
To begin with, let's figure it out, because of which the eyes begin to get tired when working at the computer. With long sitting in front of the monitor, the load increases on many muscle groups - the muscles of the arms, neck, and back receive additional tension. But most of all, the eye muscles get tired. This is due to the fact that a person sitting in front of a computer needs a certain concentration of attention, as well as a change in the method and speed of reading.
In addition, the technical features of many monitors lead to the fact that at the computer the user starts blinking three times less 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, false myopia can also develop), a feeling of dryness and burning in the eyes, pain during eye movement, as well as pain in the eye sockets and forehead. Now let's look at how to set up the monitor in such a way as to minimize the load on the eye muscles during operation and avoid the appearance of these unpleasant symptoms.
One of the main factors influencing eye fatigue while working at a computer is the contrast and brightness indicators of the display. To understand how to optimize your computer monitor, you need to know a few nuances of how our eyes react to brightness. In order to minimize eye strain, it is necessary to adjust this parameter so that the brightness of the monitor matches the brightness in the room. If the room is very light, you need to “wind up” this parameter a little on the monitor, and if it’s rather dim (or if you like to sit at the computer at night), then lower it. The body itself can tell you how to properly set up the monitor - in bright light in a room, the image on the monitor will appear insufficiently saturated, and in moderate light it will appear too bright. You just need to experiment a little, and you can choose the best option for the brightness level.
But since technology does not stand still, leading display manufacturers saved us from constant brightness adjustment by releasing Smart monitors. The displays of these devices adjust automatically to environmental lighting. How to set up a monitor if it does not have a Smart function? The easiest way is to open a blank sheet in MS Word, and compare its “whiteness” with the lighting around the monitor. If this sheet will dazzle and resemble a lamp, then the brightness needs to be slightly reduced. If it seems darker than its surroundings, 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 approximately 10 degrees). Behind your workstation there should be no direct light sources capable of creating glare on the display.
And now that you know how to set up the monitor correctly, let me remind you one more simple truth that helps you keep your eyes while working at the computer. An adult should not spend more than six hours in front of a monitor per day. For children and the elderly, this time should not exceed two hours at all. Do not forget about it, and your vision will always remain in the best shape!
