Vitamins to improve vision

Vitamins for improving vision: Complete nutrition for healthy eyes

Section 1: The Fundamentals of the Health of the Eye and the role of vitamins

Vision is one of the most important feelings that allows us to perceive the world in all its glory. Maintaining good vision requires an integrated approach, including regular examinations by an ophthalmologist, protecting the eyes from the harmful effects of the environment and, of course, proper nutrition. Vitamins play a key role in maintaining the health of the eyes, protecting them from various diseases and improving overall vision.

1.1 Anatomy of the eye and processes of vision

Before talking about vitamins, it is necessary to understand how the eye works. The main components of the eye include:

• Cornea: A transparent outer shell focusing light.
• Crystalik: Flexible lens, focusing light on the retina.
• Retina: A photosensitive fabric lining the back of the eye and containing photoreceptors (sticks and cones).
• Sticks: Photoreceptors responsible for vision in low light conditions.
• Knukes: Photoreceptors responsible for vision in conditions of bright light and the perception of colors.
• Vine nerve: Transfers visual information from the retina to the brain.

The process of vision begins with the fact that the light passes through the cornea and the lens that focus it on the retina. Photoreceptors in the retina convert light into electrical signals, which are transmitted through the optic nerve to the brain, where they are interpreted as an image.

1.2 The main factors affecting vision

Vision is influenced by many factors, both internal and external. The main factors include:

• Age: With age, vision can worsen due to natural aging processes, such as a decrease in the elasticity of the lens and retinal degeneration.
• Genetics: Heredity plays an important role in predisposition to certain eye diseases.
• Environment: The effect of ultraviolet (UV) radiation, air pollution and prolonged work at the computer can negatively affect vision.
• Life: Smoking, improper nutrition and lack of physical activity can increase the risk of eye diseases.
• Diseases: Some diseases, such as diabetes and hypertension, can damage the blood vessels in the eyes and lead to vision of vision.

1.3 The role of vitamins and minerals in maintaining the health of the eyes

Vitamins and minerals are important nutrients necessary for the normal functioning of all organs and systems of the body, including eyes. They play the role of antioxidants, protecting the eye cells from damage, improve blood circulation in the eyes, support the health of the retina and lens.

Section 2: Basic vitamins for improving vision

Not all vitamins are equally useful for the eyes. Some of them play a more important role in maintaining the health of the eyes than others.

2.1 Vitamin A (Retinol)

Vitamin A is a fat -soluble vitamin necessary for the normal functioning of the retina. It plays an important role in the formation of rhodopsin – a photosensitive pigment necessary for vision in low illumination. Vitamin A deficiency can lead to chicken blindness (nickthalopia) – a decrease in vision in the dark.

• Vitamin A functions in the eyes:
  • Maintaining the health of the cornea.
  • Improving vision in conditions of low illumination.
  • Prevention of dry eyes.
• Sources of vitamin A:
  • Animal sources: liver, dairy products, egg yolks.
  • Plant sources (beta-carotene, provitamin a): carrots, sweet potatoes, spinach, pumpkin, mangoes.
• Recommended daily dose:
  • For adults: 900 mcg (men), 700 mcg (women).
• Warning: An overdose of vitamin A can be toxic. It is necessary to observe the recommended doses.

2.2 Vitamin C (ascorbic acid)

Vitamin C is a powerful antioxidant that helps protect the eyes from damage caused by free radicals. Free radicals are unstable molecules that form in the process of metabolism and under the influence of external factors, such as UV radiation and environmental pollution. They can damage cells and tissues, contributing to the development of various diseases, including eye diseases.

• Vitamin C functions in the eyes:
  • Protection of eye cells from oxidative stress.
  • Improving blood circulation in the eyes.
  • Maintaining the health of blood vessels in the eyes.

• Sources of vitamin C:
  • Citrus fruits (oranges, lemons, grapefruits).
  • Berries (strawberries, blueberries, raspberries).
  • Vegetables (Bulgarian pepper, broccoli, spinach).
• Recommended daily dose:
  • For adults: 90 mg (men), 75 mg (women).
  • For smokers: you need to increase the dose by 35 mg per day.
• Warning: Vitamin C is usually safe in recommended doses. High doses can cause stomach disorder.

2.3 Vitamin E (tocopherol)

Vitamin E is another powerful antioxidant that helps to protect the eyes from damage caused by free radicals. It also plays an important role in maintaining the health of cell membranes and improving blood circulation.

2.4 lutein and zeaxanthin

Luthein and Zeaksantin are carotenoids, pigments that are found in high concentration in the retina, especially in the makula – the retina responsible for central vision. They act as antioxidants, protecting the retina from damage caused by blue light and free radicals.

• The functions of Luthein and Zeaksanthin in the eyes:
  • Filtering blue light.
  • Retinal protection from oxidative stress.
  • Reducing the risk of the development of VMD and cataracts.

• Warning: Luthein and Zeaksantin are usually safe in recommended doses.

2.5 zinc

Zinc is a mineral that plays an important role in many processes in the body, including vision. It is necessary for the normal functioning of vitamin A and helps to transfer it from the liver to the retina. Zinc is also a component of enzymes that protect the eyes from damage.

• Functions of zinc in the eyes:
  • Improving vision in conditions of low illumination.

Section 3: eyes and vitamins: evidence base

Vitamins can play an important role in the prevention and slowdown of the progression of certain eye diseases.

3.1 Age macular degeneration (VMD)

VMD is a disease that affects the macula, the retina responsible for central vision. This is one of the main reasons for loss of vision in people over 50 years old. Studies have shown that taking certain vitamins and minerals can slow down the progression of the VMD.

• AREDS and AREDS2 Research:
  • These studies have shown that the reception of the combination of vitamin C, vitamin E, beta-carotene (in areDs), lutein and zeaksanthin (in areDS2), zinc and copper can reduce the risk of progression of the EMD.
  • In Areds2, beta-carotene was replaced by Luthein and Zeaksantin, as beta-carotene can increase the risk of lung cancer among smokers.
• Recommendations:
  • People with an intermediate or late stage of the EMD are recommended to take additives containing vitamins and minerals recommended in the AREDS2 studies.
  • It is important to consult a doctor before taking additives.
