Bad for vision: Support for the health of the eyes
I. Anatomy of the eyes and key factors affecting vision
To understand the need to use dietary supplements for vision, it is important to realize the complexity and vulnerability of the visual apparatus. The eye is a highly organized organ consisting of many components, each of which plays a critical role in the formation of the image.
- Cornea: A transparent outer shell of the eye, focusing light that falls into the eye. Its smoothness and transparency are crucial for acute vision.
- Raduzhka: The colored part of the eye that regulates the amount of light passing through the pupil.
- Pupil: The hole in the center of the iris through which light falls inside. Its size changes depending on illumination.
- Crystalik: A flexible lens located behind the iris, which focuses the light on the retina. He changes his shape to provide clear vision at different distances (accommodation).
- Retina: A photosensitive fabric lining the back of the eye. It contains photoreceptors (sticks and cones), converting light into nerve impulses.
- Sticks: Photoreceptors responsible for vision in low illumination (twilight vision) and detection of movement.
- Knukes: Photoreceptors responsible for vision in conditions of bright light, color perception and visual acuity.
- Yellow spot (macula): The central region of the retina, containing a high concentration of cones and is responsible for central vision, necessary for reading, driving and recognition of persons.
- Vine nerve: Passes nerve impulses from retina to brain, where they are interpreted as visual images.
- Matching: White, opaque outer shell of the eye, providing protection and support.
- Vascular shell: A layer of fabric between the sclera and the retina containing blood vessels that feed the eyes.
- Glass: A gel -like substance that fills the space between the lens and the retina, supporting the shape of the eye and provides transparency.
Various factors affect vision, including:
- Age: With age, natural visual impairment occurs, associated with changes in the lens (cataract development), retina (age -related macular degeneration) and visual nerve (glaucoma).
- Genetics: The hereditary predisposition plays a significant role in the development of many eye diseases.
- Environment: The effects of ultraviolet radiation, air pollution and excessive load on the eyes (for example, long -term work at the computer) can negatively affect vision.
- Nutrition: The deficiency of certain vitamins and minerals can lead to a deterioration in vision and the development of eye diseases.
- Chronic diseases: Diabetes, hypertension and other chronic diseases can damage blood vessels in the eye and lead to loss of vision.
- Smoking: Smoking increases the risk of cataracts, age -related macular degeneration and other eyes of the eyes.
- Infections and injuries: Eye infections and injuries can damage the structures of the eye and lead to visual impairment.
II. The main vitamins and minerals necessary for the health of the eyes
The optimal functioning of the visual apparatus requires the constant receipt of certain vitamins and minerals. The disadvantage of these substances can lead to various visual impairments.
- Vitamin A (Retinol): It is necessary for the formation of a rhodopsin, a photosensitive pigment in sticks responsible for vision at dusk. Vitamin A deficiency can lead to “chicken blindness” (nickthalopia), dryness of the cornea (xerophthalmia) and other vision problems. Good sources: liver, carrots, pumpkin, spinach, broccoli.
- Vitamin C (ascorbic acid): A powerful antioxidant that protects the eye cells from damage by free radicals. Participates in the synthesis of collagen necessary to maintain the structure of the cornea and lens. Reduces the risk of cataracts and age -related macular degeneration. Good sources: citrus fruits, berries, kiwi, pepper.
- Vitamin E (Tokoferol): Another important antioxidant protecting cell membranes from oxidative stress. Reduces the risk of cataracts and age -related macular degeneration. Good sources: vegetable oils (sunflower, olive), nuts, seeds, avocados.
- B vitamins B: They play an important role in maintaining the health of the nervous system, including the visual nerve. B vitamins deficiency can lead to optic neuritis and other visual impairments. Good sources: whole grain products, meat, fish, eggs, dairy products, green leafy vegetables. Specific B vitamins, important for vision, include:
- Vitamin B1 (TIAMIN): Supports the normal function of the optic nerve.
- Vitamin B2 (Riboflavin): It is necessary for the health of the cornea and the lens.
- Vitamin B3 (Niacin): Improves blood circulation in the eye.
- Vitamin B6 (Pyridoxin): Participates in the metabolism of neurotransmitters necessary for the normal functioning of the optic nerve.
- Vitamin B12 (cobalamin): It is necessary for the health of nerve cells, including optic cells.
- Lutein and Zeaxanthin: Carotinoids that accumulate in the macula and protect it from damage to blue light and oxidative stress. Reduce the risk of developing age -related macular degeneration and cataracts. Good sources: spinach, cabbage, broccoli, corn, egg yolk.
- Zinc: It is necessary for transporting vitamin A from the liver to the retina. Plays an important role in maintaining the health of the macula. Zinc deficiency can lead to vision of vision and the development of age -related macular degeneration. Good sources: meat, seafood, nuts, seeds, legumes.
- Selenium: An antioxidant protecting the eye cells from damage by free radicals. Participates in maintaining the health of the lens. Good sources: Brazilian nuts, fish, meat, eggs.
- Omega-3 fatty acids (DGK and EPK): Important structural components of cell membranes in the retina. Support the health of the retina and reduce the risk of developing age -related macular degeneration and dry eye syndrome. Good sources: fatty fish (salmon, tuna, herring), linseed oil, walnuts, chia seeds.
III. The role of dietary supplements in maintaining the health of the eyes
Bades (biologically active additives) can be a useful addition to the diet to maintain eye health, especially in cases where it is difficult to get a sufficient amount of necessary vitamins and minerals from food. However, it is important to remember that dietary supplements are not a replacement of a balanced diet and a healthy lifestyle.
- Prevention of age -related changes: Bades containing antioxidants (vitamins C and E, selenium), lutein and zeaxantin, omega-3 fatty acids can help slow down age-related changes and reduce the risk of cataracts, age-related macular degeneration and other diseases.
- Improving visual acuity: Bades containing Luthein and Zeaxantin can improve visual acuity and contrast, especially in people with age -related macular degeneration.
- Support for the health of the retina: Dietary supplements containing omega-3 fatty acids can maintain retinal health and reduce the risk of retinal diseases, such as diabetic retinopathy.
- Reducing symptoms of dry eye syndrome: Dietary supplements containing omega-3 fatty acids can reduce the symptoms of dry eyes, such as dryness, burning and itching in the eyes.
- Support for optic health: Bades containing B vitamins can maintain the optic health and reduce the risk of developing the optic nerve and other disorders.
- Filling a deficiency of nutrients: Bades can help replenish the deficiency of vitamins and minerals necessary for the health of the eyes, especially in people with unbalanced diet or increased need for nutrients (for example, in older people, pregnant women, people with chronic diseases).
- Protection from the effects of negative environmental factors: Bades containing antioxidants can protect the eye cells from damage by ultraviolet radiation, air pollution and other negative environmental factors.
