Vitamins for the eyes: for children and adults

Chapter 1: Anatomy of the Eyes and the role of vitamins

To understand the need for vitamins for the eyes, it is necessary to realize the complexity and vulnerability of the visual apparatus. The eye is a complex system consisting of many components, each of which performs its own specific function.

• Cornea: Transparent front of the eye, focusing light.
• Crystalik: Elastic lens, additionally focusing light on the retina.
• Retina: A photosensitive fabric lining the back of the eye. Contains photoreceptors (sticks and cones), converting light into nerve impulses.
• Makula: The central part of the retina, responsible for acute vision.
• Vine nerve: Transfers nervous impulses from retina to brain.
• Sclera: The white shell of the eye providing protection.
• Vascular shell: Contains blood vessels that feed the eyes.
• Raduzhka: The color of the eye that controls the amount of light falling into the eye.

Each of these components is subject to the influence of external and internal factors, including age -related changes, the effects of ultraviolet radiation, adverse ecology and a deficiency of nutrients. Vitamins play a key role in maintaining the health and functionality of each component of the eye. They act as antioxidants, protecting the cells from damage by free radicals, participate in the metabolic processes necessary for the normal functioning of the visual apparatus, and support the structure of the eye tissues.

1.1. Free radicals and oxidative stress

Free radicals are unstable molecules formed in the body as a result of normal metabolic processes, as well as under the influence of external factors, such as environmental pollution, smoking and ultraviolet radiation. They damage cells, causing oxidative stress. Oxidative stress plays an important role in the development of many eye diseases, including cataracts, age -related macular degeneration (VMD) and glaucoma.

The antioxidants contained in vitamins neutralize free radicals, preventing damage to the eye cells and protecting from the development of age -related changes and diseases.

1.2. The influence of age on vision

With age, the natural processes of cell renewal slow down, which leads to visual impairment. The lens loses elasticity, which makes it difficult to focus on close objects (presbyopia). The retina becomes more vulnerable to damage, which increases the risk of EMD. The production of tear fluid is reduced, which leads to dry eyes.

Vitamins and other nutrients can slow down these processes and help maintain vision for many years.

Chapter 2: The main vitamins for the health of the eyes

There are several vitamins and nutrients that are especially important for maintaining the health of the eyes.

• Vitamin A: It is necessary for the formation of a rhodopsin – a pigment that allows you to see in low light conditions. Vitamin A deficiency can lead to night blindness (nickthalopia) and dry eyes (xerophthalmia). He also plays an important role in maintaining the health of the cornea and conjunctiva.

  • Sources: Carrots, pumpkin, sweet potatoes, spinach, liver, eggs, dairy products.

• Vitamin C: A powerful antioxidant protecting the eyes from damage by free radicals. It also plays a role in the synthesis of collagen, which is necessary to maintain the structure of the eye tissue, especially the cornea and the lens. Studies show that vitamin C can reduce the risk of cataracts and the VMD.

  • Sources: Citrus fruits, strawberries, kiwi, pepper, broccoli, Brussels cabbage.

• Vitamin E: Another powerful antioxidant that protects the eye cells from damage by free radicals. It is especially important for protecting cell membranes containing polyunsaturated fatty acids. Vitamin E can also help prevent the development of cataracts and the VMD.

  • Sources: Vegetable oils, nuts, seeds, avocados, spinach.

• B vitamins B: (B1, B2, B3, B6, B9, B12) play an important role in the energy metabolism of the eye cells and maintaining the health of the nervous system, including the visual nerve. B vitamins deficiency can lead to various visual impairments, including the optic neuritis and dry eye syndrome.

  • Sources: Grain products, meat, poultry, fish, eggs, dairy products, legumes, green leafy vegetables.

• Lutein and Zeaxanthin: Carotinoids that accumulate in the Makula – the central part of the retina responsible for acute vision. They act as filters, absorbing harmful blue light and protecting the macule from damage by free radicals. Studies show that Luthein and Zeaxantin can reduce the risk of EMD and cataracts.

  • Sources: Dark green leafy vegetables (spinach, cabbage), corn, eggs.

• Omega-3 fatty acids: Important to maintain the health of the retina and reduce inflammation. They also play a role in maintaining the normal function of the lacrimal glands and can help alleviate the symptoms of dry eye syndrome.

  • Sources: Fat fish (salmon, tuna, sardines), linen seeds, walnuts, chia seeds.

• Zinc: It is necessary for the normal functioning of enzymes involved in the metabolism of vitamin A and antioxidant protection. He also plays a role in maintaining the health of the retina and lens.

  • Sources: Meat, poultry, seafood, legumes, nuts, seeds.

• Selenium: An antioxidant working paired with vitamin E to protect cells from damage to free radicals.

  • Sources: Brazilian nuts, seafood, meat, poultry, eggs.

Chapter 3: Vitamins for children: development and protection of vision

Vision plays an important role in the development of the child, providing him with the opportunity to know the world, learn and interact with the environment. Proper nutrition, rich in vitamins and minerals, is necessary for the normal development of vision and protection against possible violations.

3.1. The importance of vitamins for developing vision

During the period of active growth and development, especially in the first years of life, the need for vitamins and minerals increases significantly. The deficiency of the necessary nutrients can negatively affect the development of the visual apparatus and lead to various vision problems.
