Computers have long been firmly rooted in our lives. Both work and leisure of many people are closely related to the computer. Some of us are not able to spend a single day without this "miracle of technology." But not every user is aware of the degree of load to which his eyes are exposed. In the XXI century, a new disease arose, called "computer visual syndrome."
Its main symptoms include: headache, blurred vision, fatigue, redness of the eyes. A burning sensation appears in the eyes, a feeling of dryness, often lacrimation begins. Why is this happening and how to deal with such unpleasant manifestations?
The negative effect of the computer (laptop) on the eyes
With a daily pastime at the computer for more than 4 hours, the visual system experiences a significant load . When working with this kind of eyes, they noticeably get tired, and the mucous membrane dries out. To prevent these unpleasant consequences, you need to use special glasses.
Glasses for working at a computer are made so that in the process of such work the organs of vision are minimally damaged. But even with this in mind, you should occasionally get out of the chair for at least 10-15 minutes . You can distract yourself by looking out the window and trying to peer into the distance or just relax a bit.
Reference! In such products, special protective coatings made of darkened glass are used. Such coatings help block electromagnetic radiation from the monitor and provide the eyes with constant flickering of the monitor.
The main goal of computer glasses is to make your eyes blink, and slightly increase clarity.
The main errors when working on a computer
The most common mistakes made when working on a computer are the following:
- continuous work without rest and performing gymnastics for the eyes for more than 45 minutes;
- the location of the monitor below or above eye level;
- dusting the display and the workplace;
- being at a distance of less than 50-60 cm to the monitor;
- prolonged stay in one position;

- erroneous settings for contrast, brightness and refresh rate of the display;
- work in a poorly lit room.

Do glasses help to work at a computer?
In practice, such products are really beneficial. The use of optical (in some cases, and mineral) lenses made it possible to achieve certain successes in reducing damage to the eye mucosa . In addition, such goggles increase sharpness, protect against ultraviolet radiation and relax muscles.

You should not go out with such glasses on the street. The cornea of the eyes should be regularly exposed to ultraviolet rays. Special safety glasses for working at a computer make it difficult for such rays to access the eyes, thereby adversely affecting the visual system.

- reduction of fatigue and eye strain due to redistribution of focal load;
- improving the quality of the visible image;
- protection of the lens of the eye from the harmful effects of rays;
