The first is blinking. With increased attention to information on the monitor, people usually forget to blink. The task of blinking is to moisturize and wash the eyeball. If you stop blinking, the surface of the cornea begins to dry out and get irritated. This means that dehydration occurs. As a result, the protective mechanisms of the eyes may be weakened, manifested, for example, by a cut in the eyes or photophobia.
There is still such a thing as accommodation. Accommodation is the ability of the lens to flexibly change its shape. If the flexibility of the lens is normal, then objects at different distances are clearly visible, since they are in focus. When working with a computer, the distance from the eyes to the monitor does not change much, and the pupil remains in the same position for a long time. The unused muscles responsible for accommodation begin to weaken, and the ability of the pupil to change its shape deteriorates.
And on the third we burn out the retina. Most of all can suffer from the light beating in the eyes of the screen, those who work a lot with the text. Retinal cells for a long time receive even homogeneous information against the backdrop of intensive exposure. As a result, there is a decrease in the power of vision and the ability to see in the dark.
How to preserve and improve vision, what should I do to work fully at the computer and at the same time to preserve my health?
The first help to the eyes can be rest. Sleep usually removes all the problems of the day. But if the next day in the eyes there is some discomfort, it seems that it is time to take care of your vision.
But it is better not to wait, when in the eyes there will be unhealthy sensations, and to be engaged in prophylaxis. Firstly, we must rest every 10 to 15 minutes. Secondly, it's time to spend on doing exercises.
Here they are:
• Stand at the window. Select a distant subject. Look at the deleted object, then look at a nearby object, for example, your own finger, which is placed on the same line with the deleted object. Perform ten times.
• Watch moving objects in the distance.
• Close eyes with wide open eyes. Make four to five times.
• Rotate your eyes in different directions.
• Blink a couple of minutes at a time. There are cases when one blink greatly improved vision.
To keep good eyesight, here are some more practical tips. The monitor should be located at least half a meter from the eyes. The center of the monitor screen should be 20 cm below the direct view. The monitor should not have any glare. The best lighting is the ceiling lights, the light from which falls on the ceiling. There should be a local lamp near the computer. The best place for a desktop with a computer is from where you can see the far corner of the room and further, if there is an open door to the next room. If you look at the wall, you need to hang a mirror on it.
Our life is filled with other stresses, except for work on the computer, which encroach on the health of the eyesight. Therefore, if there are concerns related to the eyes, it is necessary to support them, and maybe even improve their health and restore the former clarity, the naturalness of colors and work capacity.
In addition to exercises, you can make lotions, for example, from puffiness under the eyes. Here are a few masks for eyelids, which are recommended in the morning and evening. Usually a mask or lotion is enough for 10 - 25 minutes. On the eyes apply moistened in infusion or decoction of napkins.
• Infusion of arnica (10 - 15 drops per quarter of a glass of water).
• broths of chamomile or parsley.
• Mask of raw potatoes. A couple of tablespoons of grated potatoes spread out into two gauze napkins, wrap and hold on the eyelids the right time.
• Contrast compresses with sage infusion will more effectively help get rid of bags under the eyes.
Sometimes the eyes get tired of the intense color scheme. It is known that yellow-green and bluish-green colors favorably act on the eyes, while red and blue-violet ones are on the contrary.
To really learn How to save and improve your vision when working on a computer, and not only that, it is recommended to read the well-known books by William Bates "How to improve vision without glasses" and Grant Demirchoglyan "How to preserve and improve vision."
