Everyone is obliged to take care of their eyes. Eye hygiene is a set of measures aimed at preserving and maintaining good vision, preventing many eye diseases. Hygiene of vision involves following certain rules.
First, it is imperative that the light was correct during the reading. This will save your eyes from overexertion.
When reading, the light source should be located above and behind the reader so that the light falls from over the shoulder. It is forbidden to read if the light is shining into the face.
The lighting of the room where the person is reading should be quite bright. It is impossible to read in the twilight, as this deteriorates vision. The desktop should be positioned so that the window or other light source is on the left.
An artificial light source, for example, a table lamp, must necessarily be covered with a shade, since direct light rays would otherwise cut the eyes. When reading with a table lamp on, it is also better to leave the main lighting on – this will create a smooth transition from less intense light to more intense.
Too intense light blinds the eyes, causes overexertion of vision, as a result of which the eyes get tired quickly. In addition, it is harmful to read, for example, in a driving car, since the text is shaken at different distances from the eyes.
In vision hygiene, it is very important to maintain the correct distance between the eyes and the text, which should be at least thirty centimeters. When looking at something from a close distance, the eye muscles tense, and the eyes again get tired.
Modern society cannot imagine its life without computers. But, unfortunately, computers not only make our life easier, but also harm our eyes, especially for those people who constantly work in front of the monitor. We recommend doing a few simple exercises to relieve eye strain while using your computer.
During operation, the computer monitor should be located at least arm’s length. In addition, the monitor should be positioned on the desktop so that, looking up, you can see everything in the room. After forty minutes of working at the computer monitor, you need to take a break, do light exercises, for example, frequent blinking, during which the eyes relax and moisturize the secretions of the lacrimal glands.
To prevent myopia, you need to expose yourself to ultraviolet rays. In the case of a shortage of ultraviolet rays, a violation of the metabolism of phosphorus and calcium occurs. For this reason, the adaptive capacity of the eyes is reduced. Under the influence of the sun’s rays, vitamin D, which is in the cells of the skin, becomes active and normalizes the correct absorption of phosphorus and calcium compounds in the body.
Balanced nutrition plays a huge role in eye hygiene, which should include the required amount of vitamins, in particular “eye” vitamins A and D. Vitamin D is included in such foods as beef liver and sea herring, egg yolk and natural butter.
Vitami A is extremely important for vision, as it is responsible for the eye’s ability to see at dusk. With a deficiency of this vitamin, visual acuity is upset, the skin loses its tone, becomes vulnerable to inflammatory processes. Vitamin A is found in abundance in cod liver, cream, and chicken eggs. There is also such a substance as provitamin A, called carotene. Carotene is necessary in the human body for the synthesis of vitamin A. There is a lot of carotene in carrots and bell peppers, rose hips and onions, apricots and lettuce.
