Natural sources of vitamins for the eyes: complete guidance for preserving visual health

Section 1: Vitamin A – the basis of the health of the cornea and night vision

Vitamin A, also known as retinol, plays a key role in maintaining the health of the eyes. It is necessary for the normal functioning of the cornea, a transparent front of the eye, as well as to adapt vision in conditions of low illumination. Vitamin A deficiency can lead to serious vision problems, including night blindness, dry eyes and even irreversible damage to the cornea.

  • The mechanism of action: Vitamin A is a component of rhodopsin, a photosensitive pigment contained in the wipes of the retina. The sticks are responsible for vision in conditions of weak light. With a lack of vitamin A, the formation of rhodopsin is disturbed, which leads to a deterioration in night vision. In addition, vitamin A contributes to the maintenance of the health of epithelial tissues, including the cornea, protecting it from dryness and infections.

  • Sources of vitamin A:

    • Animal sources:

      • Liver: The liver (beef, chicken, pork) is one of the richest sources of vitamin A. Regular use of the liver (in moderation) can significantly increase the level of vitamin A in the body.
      • Egg yolks: Egg yolks contain a significant amount of vitamin A, as well as other beneficial nutrients, such as lutein and zeaxantin.
      • Dairy products: Milk, cheese, butter and other dairy products contain vitamin A, especially products with a high fat content.
      • Fish oil: Fish oil is an excellent source of vitamin A, as well as omega-3 fatty acids, which are useful for the health of the eyes and the whole organism.

    • Plant sources (provitamin A-beta-carotene):

      • Carrot: Carrots are one of the most famous sources of beta-carotene, the predecessor of vitamin A. Beta-carotene is transformed into vitamin A in the body.
      • Sweet potato: Sweet potatoes are also rich in beta carotene, as well as vitamin C and fiber.
      • Pumpkin: The pumpkin contains a significant amount of beta-carotene, as well as other antioxidants.
      • Spinach: Spinach is a good source of beta-carotene, as well as Lutheina and Zeaksanthin.
      • Kale cabbage: Kale cabbage is also rich in beta-carotene, as well as vitamins C and K.

      • Apricots: Apricots contain beta-carotene, as well as vitamin C and potassium.
      • Mango: Mango is a good source of beta-carotene, as well as vitamin C and fiber.

  • Recommendations for use: The recommended daily dose of vitamin A varies depending on age, gender and physiological condition. It is important not to exceed the recommended dose, since an excess of vitamin A can be toxic. Consultation with a doctor or nutritionist will help determine the optimal dose of vitamin A for your individual needs.

  • Important factors: The effectiveness of the conversion of beta-carotene into vitamin A depends on various factors, including the state of health of the intestine, the presence of a sufficient amount of fat in the diet (for the assimilation of beta-carotene) and genetic characteristics. People with digestive problems or lack of fats in the diet may require a larger amount of beta-carotene to achieve an adequate level of vitamin A.

Section 2: Vitamin C – antioxidant protection and strengthening of eye vessels

Vitamin C, also known as ascorbic acid, is a powerful antioxidant that plays an important role in protecting the eyes from damage to free radicals. Free radicals are unstable molecules that can damage cells and contribute to the development of various diseases, including cataracts and age -related macular degeneration (VMD). Vitamin C is also necessary for the synthesis of collagen, protein, which provides the structure and strength of tissues, including the vessels of the eyes.

  • The mechanism of action: Vitamin C neutralizes free radicals, preventing their damaging effect on eye cells. It also strengthens the walls of blood vessels, improving the blood supply to the retina and other eye structures. In addition, vitamin C can help reduce intraocular pressure, which is important for the prevention of glaucoma.

  • Important factors: The assimilation of Luthein and Zeaksanthin improves when they are used along with fats. Smoking reduces the level of lutein and zeaxantin in the body, so it is recommended to consume more products rich in these carotenoids.

Section 5: Omega-3 fatty acids-maintaining the health of the retina and reducing dry eyes

Omega-3 fatty acids, especially DGK (non-zahexaenic acid) and EPK (eicophantamentenoic acid), play an important role in maintaining the health of the retina and reduce dry eyes. DGC is the main structural component of the retina, and EPC has anti -inflammatory properties.

  • The mechanism of action: DHC is an important building material for retinal cells and helps maintain its normal function. EPC reduces inflammation in the lackeys and on the surface of the eye, which helps alleviate the symptoms of dry eyes.

  • Sources of omega-3 fatty acids:

    • Fat fish:

      • Salmon: Salmon is one of the richest sources of omega-3 fatty acids.
      • Skumbry: The mackerel contains a significant amount of omega-3 fatty acids.
      • Tuna: Tuna also contains omega-3 fatty acids, but it should be consumed in moderation due to the possible content of mercury.
      • Herring: Herring is a good source of omega-3 fatty acids.
      • Sardins: Sardins contain omega-3 fatty acids and other beneficial nutrients.

    • Plant sources:
