Useful for the eyes: vitamin diet

Chapter 1: The foundation of visual health – food

Vision is one of the most valuable feelings that allows us to perceive the world around us in all its glory. Maintaining the severity and health of the eyes requires an integrated approach, including regular examinations by an ophthalmologist, a sufficient rest and, importantly, a balanced diet rich in vitamins and nutrients. The lack of certain vitamins and minerals can lead to various problems with vision, from dry eyes and fatigue to more serious diseases, such as cataracts and degeneration of the yellow spot. In this article, we will examine in detail the role of vitamins and nutrients in maintaining the health of the eyes, as well as offer specific products and dietary strategies to improve and preserve visual function.

1.1 The role of antioxidants in eye protection

Eyes constantly exposed to light and oxygen are especially vulnerable to oxidative stress. Oxidative stress occurs when a balance between free radicals (unstable molecules that damage cells) and antioxidants (substances that neutralize free radicals) is disturbed. In the eyes, oxidative stress can damage the cells of the retina, lens and other structures, contributing to the development of age -related diseases of the eyes.

The antioxidants contained in various foods play a decisive role in protecting the eyes from oxidative stress. They neutralize free radicals, preventing damage to cells and tissues. The most important antioxidants for the health of the eyes include vitamins C and E, zinc, selenium, lutein and zeaxantin.

1.2 Key vitamins and minerals for the health of the eyes

Certain vitamins and minerals are necessary to maintain optimal visual function and prevent eye diseases. Consider the main ones:

• Vitamin A: He plays a key role in the formation of a rhodopsin, a photosensitive pigment in the retina necessary for vision in low light conditions. Vitamin A deficiency can lead to chicken blindness (nickthalopia), dry eyes (xerophthalmia) and even blindness. Vitamin and also important for the health of the cornea.
• Vitamin C (ascorbic acid): A powerful antioxidant protecting the eyes from damage by free radicals. Vitamin C helps to strengthen blood vessels in the eyes and can reduce the risk of cataracts and age -related macular degeneration (EMD).
• Vitamin E (tocopherol): Another important antioxidant that protects the eye cells from oxidative damage. Vitamin E helps to prevent cataracts and VMD, especially in combination with other antioxidants.
• B vitamins B (B1, B2, B3, B6, B12, Folic acid): These vitamins play an important role in maintaining nerves health, including the optic nerve. B vitamins deficiency can lead to optic neuritis and other vision problems. Vitamin B2 (riboflavin) is important to prevent cataracts.
• Lutein and Zeaxanthin: Carotinoids concentrating in the retina, especially in the maculus (yellow spot), areas responsible for central vision. Luthein and Zeaksantin act as blue light filters, protecting the retina from damage, and have antioxidant properties. They reduce the risk of the development of VMD and cataracts.
• Zinc: It is necessary for transporting vitamin A from the liver to the retina. Zinc is also a component of many enzymes involved in the metabolism of the retina. Zinc deficiency can lead to a deterioration in night vision and increase the risk of developing the VMD.
• Selenium: An antioxidant working synergically with vitamin E to protect eye cells from oxidative damage. Selenium helps to prevent cataracts and VMDs.
• Omega-3 fatty acids: Important for maintaining the health of the retina and prevent dry eyes. Omega-3 fatty acids reduce inflammation and improve the function of the lacrimal glands.
