Vitamins for the eyes when working at a computer: a comprehensive guide for protecting vision in the digital era
Section 1: Visual overload when working at a computer: problems and consequences
Constant interaction with digital devices, especially computers, has become an integral part of modern life. However, this necessity is associated with certain risks for the health of the eyes. A long stay in front of the screen causes a number of problems combined under the general term “Computer Vision Syndrome, CVS), or” Digital Eye Strain).
1.1 The main symptoms of computer vision syndrome:
CVS is manifested in various symptoms, the intensity of which varies depending on the duration of work, the individual characteristics of the body and environmental conditions. The most common symptoms include:
- Dryness and feeling of sand in the eyes: This is due to a decrease in blinking frequency while working at the computer. The normal blinking frequency is about 15-20 times per minute, but with concentration on the screen, it decreases to 5-7 times. This leads to insufficient moisture of the cornea and the occurrence of a feeling of dryness, burning and discomfort.
- Redness and fatigue of the eyes: Long -term tension of the eye muscles, especially those that are responsible for focusing, leads to their overwork and inflammation. This is manifested in the redness of the eyeballs, the feeling of severity for centuries and the general fatigue of the eyes.
- Visualness of vision: Violation of focusing caused by overstrain of the ciliary muscle (muscles responsible for accommodation) leads to temporary blurring of vision, especially when translating the view from a close object to a distant one.
- Headaches: The tension of the eye muscles can provoke headaches, especially in the forehead and temples.
- Pain in the neck and shoulders: Incorrect posture while working at the computer, caused by the need to lean forward for better visibility, can lead to pain in the neck and shoulders.
- Photosensitivity: Increased sensitivity to bright light is also a common CVS symptom.
- Dangling in the eyes: In rare cases, with a strong overwork of the eye muscles, temporary double in the eyes may occur.
1.2 Factors aggravating computer vision syndrome:
Some factors can significantly aggravate CVS symptoms. These include:
- Incorrect organization of the workplace: The non -optimal distance to the screen, the incorrect height of the monitor, poor lighting and lack of breaks in operation.
- Dry air indoors: Work in a room with air conditioning or central heating can lead to increased dryness of air and aggravate dry eyes.
- Incorrect refraction: The presence of non -diagnosed or incorrect myopia, farsightedness or astigmatism significantly increases the load on the eyes when working at the computer.
- Age: With age, the ability of the eyes to accommodation (focus) is reduced, which makes older people more susceptible to CVS.
- Insufficient amount of sleep: The lack of sleep and general rest reduces the ability of the eyes to restore and increases the risk of CVS.
- Inal meals: The deficiency of certain vitamins and minerals necessary for the health of the eyes can also contribute to the development of CVS.
1.3 consequences of long -term exposure to CVS:
Ignoring CVS symptoms and the lack of preventive measures can lead to serious consequences for the health of the eyes. These include:
- Chronic dry eyes: A constant violation of the lacrimal film can lead to the development of chronic dry eyes, requiring the constant use of artificial tears.
- Brotherhood progression: Long -term tension of the eye muscles can contribute to the progression of myopia, especially in children and adolescents.
- Increased risk of glaucoma development: Some studies associate long -term work at a computer with an increased risk of glaucoma development, although this issue requires further study.
- Reducing visual acuity: Chronic eye overwork can lead to temporary or even a constant decrease in visual acuity.
- Deterioration of the quality of life: Constant headaches, eye fatigue and blurred vision can significantly worsen the quality of life and reduce performance.
Section 2: The role of vitamins and minerals in maintaining the health of the eyes when working at the computer
Proper nutrition plays a key role in maintaining the health of the eyes and reducing the risk of CVS development. Certain vitamins and minerals have a favorable effect on vision and help protect the eyes from the negative effects of digital devices.
2.1 The main vitamins and minerals for the health of the eyes:
- Vitamin A: It is necessary for the normal operation of the retina and maintaining good vision in low light conditions. It is also important for the health of the cornea and preventing dry eyes. Sources: carrots, pumpkin, sweet pepper, spinach, broccoli, liver, eggs.
- Vitamin C: A powerful antioxidant that protects the eyes from damage by free radicals. It also participates in the synthesis of collagen necessary to maintain the structure of the eyes. Sources: citrus fruits, berries, kiwi, sweet pepper, broccoli, spinach.
- Vitamin E: Another powerful antioxidant that protects cell membranes from damage by free radicals. It also improves blood circulation in the eyes. Sources: vegetable oils, nuts, seeds, avocados, spinach.
- Lutein and Zeaxanthin: Carotinoids that accumulate in the retina and protect it from damage to blue light, emitted screens of computers and other digital devices. They also reduce the risk of developing age -related macular degeneration (VMD) and cataracts. Sources: spinach, cabbage, broccoli, corn, eggs.
- Omega-3 fatty acids: It is necessary for the health of the lacrimal film and preventing dry eyes. They also have anti -inflammatory properties and can reduce the risk of EMD. Sources: fatty fish (salmon, tuna, sardines), linen seed, chia seeds, walnuts.
- Zinc: It is necessary for the normal operation of vitamin A and participates in the transport of vitamin A from the liver to the retina. It is also an important antioxidant and protects the eyes from damage to free radicals. Sources: meat, poultry, seafood, nuts, seeds, legumes.
- Selenium: An antioxidant that protects the eyes from damage by free radicals. It is also necessary for the normal functioning of the thyroid gland, which plays an important role in maintaining the health of the eyes. Sources: Brazilian nuts, seafood, meat, poultry, eggs, mushrooms.
2.2 mechanisms for the action of vitamins and minerals on the health of the eyes:
Each vitamin and mineral has a specific effect on the health of the eyes, contributing to their normal work and protecting them from negative factors.
- Antioxidant Protection: Vitamins C and E, zinc and selenium are powerful antioxidants that neutralize free radicals – unstable molecules that damage eye cells and contribute to the development of various diseases, such as cataracts and VMD.
- Protection from blue light: Luthein and Zeaksantin filter harmful blue light emitted by computers and other digital devices, protecting the retina from damage and reducing the risk of developing VMD.
- Moisturization of the eyes: Omega-3 fatty acids support the health of tear film, preventing dry eyes and providing comfortable vision when working at the computer.
- Support for visual function: Vitamin A is necessary for the normal operation of the retina and maintaining good vision in conditions of low illumination. He also participates in the process of visual adaptation to darkness.
- Improving blood circulation: Some vitamins and minerals, such as vitamin E, improve blood circulation in the eyes, providing them with a sufficient amount of oxygen and nutrients.
2.3 Recommended dosages of vitamins and minerals:
Recommended dosages of vitamins and minerals to maintain eye health depend on age, gender, health and lifestyle. It is important to consult a doctor or nutritionist in order to determine the optimal dosage for each specific case.
In general, the recommended daily dosages to maintain eye health when working at the computer include:
- Vitamin A: 700-900 mcg
- Vitamin C: 75-90 mg
- Vitamin E: 15 mg
- Luthein: 10 mg
- Zeaksantin: 2 mg
- Omega-3 fatty acids: 1000-2000 mg
