Treatment of CVS or computer vision syndrome Kyiv

When working at a computer, a person may experience a number of unpleasant sensations, which received the name computer vision syndrome (computer vision syndrome). This term defines a set of complaints about the organs of vision, quick fatigue, pain in the region of cervical vertebrae in people, who spend a long time in front of the monitor. Moreover, the greatest load falls on the eyes, since by means of sight man receives 90% information.

Such complaints include a decrease in visual acuity, slow speed of refocusing from near objects to far ones, burning and feeling of sand in the eyes, pain in the eye sockets and forehead. These phenomena are united by the term "asthenopia" (lack of eyesight). These complaints are found in a significant percentage of users and depend both on the time of continuous work, as well as from her character. Reading information from the display is considered less burdensome, its introduction is more burdensome. The most general fatigue is caused by work in dialog mode and computer graphics. The reason for this condition is the peculiarity of the images on the monitor, when the letters, numbers and pictures do not consist of continuous lines, as on paper, and from separate points (pixels), in addition, they glow and flicker. These points do not have clear borders, so the marks and lines are less contrasty, than, let's say, in the book.

Monitor manufacturers are actively working to create monitors that are safe for health. Thanks to their efforts and growing sanitary requirements, new monitors appear with a greater degree of protection and, accordingly, with less adverse effects on the eyes.
Can be considered established, what affects the PC user the most is intense visual work with the monitor and the lack of correction for existing visual anomalies.

How to deal with CVS? The recommendations of most doctors are reduced to limiting work at the computer, what, Unfortunately, sometimes it is completely impossible.

Controlled workplace lighting is a real way to combat visual fatigue, correct ergonomic principles of its equipment and optimal vision correction (correction of myopia or farsightedness taking into account the astigmatic component).

In addition to dioptric correction, a special coating of eyeglass lenses can play a significant role. If a person works under the lighting of ordinary incandescent lamps or natural lighting, then anti-reflective coating can be recommended to her. Thanks to it, the quality of lenses as a means of vision correction improves — the transmission of light increases, and they become practically invisible, and the user gets rid of reflections, that interfere. If the workplace is illuminated by fluorescent daylight lamps, then, in addition to anti-glare, it is advisable to use a coating, which blocks ultraviolet and short-wave blue part of the spectrum (blue filter). In the radiation spectrum of most daylight lamps used in offices, there is excess blue short-wave radiation, which has an increased ability to disperse. Blue light affects the eye's ability to focus, and lighting workplaces with similar fluorescent sources is the cause 30% vision complaints from PC users. Glasses with a similar filter improve the ability to distinguish colors, reduce the "pixelity" of the image on the monitor, make the image on the retina clearer and more contrasty, adjust the radiation spectrum of the monitor to the maximum spectral sensitivity of the eye photoreceptors, reduce the time to detect a useful signal, block the short-wave hard part of the spectrum, which negatively affects the condition of the optical environment of the eye.

For PC users, which use contact lenses for correction, another problem appears: the amount and nature of the visual load contribute to this, what a person, sitting in front of the monitor, blinks less often, as a result, the mucous membrane of the eye is less wetted by tear fluid, less moistening of the lens, less oxygen penetrates the cornea, there is a feeling of "dry eye". In this case, the use of special moisturizing drops or artificial tears can be recommended to moisten the lens.

Of course, in modern life, one cannot do without it, and by following simple rules, such problems can be avoided.
