All this diverse information is perceived and transmitted to the consciousness of the muscular structure of the eyes. Visual strain during long hours of constant work at the computer is one of the main causes of tired eyes syndrome.
What is eye strain?
The eye is the most dynamic organ of the human body. The natural autofocus mechanism that we use to get a sharp picture at close range is based on muscle effort. Therefore, long-term concentration on nearby objects (for example, a computer monitor) entails an increase in muscle tension. In ophthalmological practice, this condition is considered as eye fatigue (asthenopia).
Symptoms of eye strain
If a person has eye fatigue, the symptoms of this condition can be conditionally divided into two groups - visual and ocular. The clinical picture that described the first category implies:
- significant decrease in visual acuity - blurring, bifurcation of the image; possible appearance of "flies", flashes, shimmering dots in front of the eyes;
- disruption of accommodation – problems with refocusing vision from near objects to objects located far away;
The second group of symptoms includes:
- a burning or cutting sensation ("sand") in the eyes;
- redness of the eyeballs, pain when they move;
- there may be lacrimation.
Eye fatigue from the computer
Medical statistics claim that 40% of people who work statically in front of a monitor experience eye fatigue from the computer every day. More than 90% of users are prone to this syndrome periodically. The severity of symptoms depends on the amount of time (without breaks) spent at the computer. In addition, the strain on the eyes depends on the nature of the work:
- smallest – when reading texts from the screen;
- average - when entering information;
- high - dialogue mode, work with computer graphics.
How to relieve eye fatigue after using the computer?
Eye fatigue syndrome significantly reduces the comfort of a person's life. It is already impossible to imagine modern life without the use of gadgets. In such conditions, the question naturally arises: "How to relieve eye fatigue after using the computer?". There are three simple rules:
- must arrange short dynamic breaks in work (every 40 minutes);
- follow the rules in the organization of the workplace - uniform lighting in the room; the distance from one worker to the monitor should be within 50 cm - 70 cm; at the same time, the center of the screen should be 12-15 cm below eye level;
- blink - consciously, quickly and often; it is a good exercise to relax tired eyes.
