The role of vitamins in protecting the eyes from the sun
Introduction: ultraviolet radiation and eye health
The sunlight, necessary for life and good health, contains ultraviolet (UV) radiation. Although the atmosphere of the Earth filters part of this radiation, a significant amount reaches the surface and can have a pernicious effect on the human body, especially on the eyes. Eyes, like the skin, are subject to the damaging effect of UV radiation, which can lead to various diseases, from temporary discomfort to serious visual impairment.
UV radiation is divided into three main types: UV-A, UV-B and UV-C. UV-C is almost completely absorbed by the atmosphere and does not pose a significant threat. UV-B radiation is partially blocked by an ozone layer, but the residual amount can cause sunburns and increase the risk of skin cancer. UV-a radiation, on the other hand, penetrates deeper into the skin and eyes, contributing to premature aging and, as it is believed, playing a role in the development of some diseases.
Eyes have certain protective mechanisms, such as blinking and narrowing of the pupil in bright light. However, these mechanisms are not always sufficient for complete protection against intensive UV radiation, especially with a long stay in the sun. A prolonged exposure to UV radiation can lead to the development of diseases such as photochetite (sunburn of the cornea), cataracts, degeneration of the yellow spot (age-related macular degeneration, VMD) and pingvolula/pherigi (conjunctiva growth).
Photochetitis, often called “snow blind”, occurs with intensive effects of UV radiation on the cornea, causing inflammation and pain. Symptoms usually take place within a few days, but repeating episodes can cause long -term damage.
Cataract is a clouding of the lens of the eye, which leads to a gradual decrease in vision. UV radiation is considered one of the main risk factors for the development of cataracts, especially Korkova.
Age macular degeneration (VMD) is a disease that affects the central part of the retina (macula) responsible for acute vision. UV radiation contributes to the oxidative stress in the retina, which is an important factor in the development of the EMD.
Pingxula and Phergy are neoplasms on the conjunctiva (a transparent membrane covering the protein of the eye). Pingxula is a small yellowish education, and phergy is a fleshy growth that can spread to the cornea and influence vision. UV radiation is one of the main risk factors for the development of these states.
The protection of the eyes from the sun is of paramount importance for preserving good vision throughout life. The use of sunglasses with protection against UV radiation, wearing a hat with wide fields and avoiding staying in the sun in peak hours-all these are important precautions. In addition, certain vitamins and nutrients play an important role in protecting the eyes from the harmful effects of UV radiation and maintaining the health of the eyes in general.
Vitamins and antioxidants: protection at the cellular level
In the fight against the destructive effect of UV radiation on the eyes, vitamins and antioxidants play a key role. They act at the cellular level, neutralizing free radicals and supporting the health of the eye tissue.
Free radicals are unstable molecules that are formed as a result of normal metabolic processes in the body, as well as under the influence of external factors, such as UV radiation and environmental pollution. They strive to “steal” electrons in other molecules, damaging them and causing a chain reaction of oxidative stress. Oxidative stress plays an important role in the development of many eye diseases, including cataracts and the VMD.
Antioxidants are substances that neutralize free radicals, giving them electrons without becoming unstable. They interrupt the chain reaction of oxidative stress and protect the cells from damage. Many vitamins have antioxidant properties and play an important role in maintaining the health of the eyes.
Vitamin A (Retinol): maintaining the health of the cornea and visual acuity
Vitamin A plays an important role in maintaining the health of the cornea, the outer transparent shell of the eye. It is necessary for the formation of a rhodopsin, a photosensitive pigment that allows us to see in low light conditions. Vitamin A deficiency can lead to dry eyes, a deterioration in night vision and, in severe cases, to xerophthalmia (drying of the cornea), which can lead to blindness.
Vitamin and is also an antioxidant that helps to protect the eyes from damage caused by free radicals formed under the influence of UV radiation. It supports the integrity of the epithelial cells of the cornea, making them more resistant to damage.
Good sources of vitamin A include liver, egg yolks, dairy products, carrots, sweet potatoes, spinach and other dark green leafy vegetables. It is important to remember that vitamin A is a fat -soluble vitamin, so for its absorption it is necessary to consume it with food containing fats.
Vitamin C (ascorbic acid): A powerful antioxidant to protect the lens
Vitamin C is a powerful antioxidant that concentrates in the lens of the eye. It helps to protect the lens from oxidative stress caused by UV radiation, and slows down the development of cataracts. Vitamin C also plays a role in the synthesis of collagen, structural protein, which supports the health of the eye tissue.
Studies have shown that people with a high level of vitamin C in the body have a lower risk of cataracts. Vitamin C can also help reduce intraocular pressure in people with glaucoma.
Good sources of vitamin C include citrus fruits (oranges, grapefruits, lemons), berries (strawberries, blueberries, raspberries), kiwi, bell pepper, broccoli and other fruits and vegetables. Vitamin C is a water -soluble vitamin, so it does not accumulate in the body and requires regular consumption.
Vitamin E (Tocopherol): Protection of cell membranes from oxidative damage
Vitamin E is another powerful antioxidant that helps protect cell membranes from oxidative damage caused by free radicals formed under the influence of UV radiation. It is especially important for protecting the retina, which contains a large amount of polyunsaturated fatty acids subject to oxidation.
Vitamin E can also help slow down the progression of the VMD. Studies have shown that the combination of vitamin E with other antioxidants (vitamin C, zinc, copper, lutein and zeaxantin) can reduce the risk of progression of the IAO to the late stage.
Good sources of vitamin E include vegetable oils (sunflower, soy, olive), nuts (almonds, hazelnuts), seeds (sunflower, pumpkin), avocados and dark green leafy vegetables. Vitamin E is a fat -soluble vitamin, so for its absorption it is necessary to consume it with food containing fats.
Luthein and Zeaksantin: Blue Light Filter and Makula Protection
Luthein and Zeaksantin are carotenoids, pigments that are contained in large quantities in the macula (central part of the retina). They act as natural “sunglasses” for the eyes, filtering harmful blue light and protecting the macula from damage caused by UV radicals and free radicals.
Luthein and Zeaksantin also have antioxidant properties and help reduce the risk of developing VMD and cataracts. Studies have shown that people with a high level of lutein and zeaxantin in the retina have a lower risk of developing these diseases.
Good sources of lutein and zeaxanthin include dark green leafy vegetables (spinach, cabbage, romen salad), egg yolks, corn and orange pepper. The body cannot independently produce lutein and zeaxantin, so it is necessary to receive them with food or additives.
Zinc: an important mineral for the health of the retina and optic nerve
Zinc is an important mineral that plays a role in many biological processes in the body, including vision. It is necessary for the normal functioning of the retina and optic nerve. Zinc is also an antioxidant and helps to protect the eyes from damage caused by free radicals.
Zinc is involved in the transport of vitamin A from the liver to the retina, where it is necessary for the formation of rhodopsin. He also plays a role in maintaining the health of the macula and reducing the risk of developing the Navy. Studies have shown that a combination of zinc with other antioxidants (vitamin C, vitamin E, copper, lutein and zeaxantin) can reduce the risk of progression of the VMD to a late stage.
Good sources of zinc include oysters, red meat, poultry, legumes, nuts and whole grains. It is important to note that excessive zinc consumption can lead to a shortage of copper, so when taking zinc additives, it is also recommended to take copper additives.
Omega-3 fatty acids: maintaining the health of the retina and reducing the risk of dry eyes
Omega-3 fatty acids are indispensable fats that play an important role in maintaining the health of the retina and reducing the risk of dry eyes. They are part of the retinal cell membranes and help maintain their flexibility and normal functioning.
Two main omega-3 fatty acids important to the health of the eyes are non-achexenoic acid (DHG) and eicoprendaenoic acid (EPK). DGC is the main structural component of the retina, and EPC has anti -inflammatory properties.
Studies have shown that people who use a sufficient amount of omega-3 fatty acids have a lower risk of developing the VMD and dry eyes. Omega-3 fatty acids can also help improve vision in people with diabetic retinopathy.
Good sources of omega-3 fatty acids include fatty fish (salmon, tuna, mackerel, sardines), linseed seed, chia seeds, walnuts and fish oil supplements.
Astaxantin: Super-powerful antioxidant to protect against UV radiation
Astaxantin is a carotenoid that has extremely powerful antioxidant properties. It is more effective than vitamin E, vitamin C and beta-carotene in neutralization of free radicals. Astaxantin is especially effective in protecting the eyes from damage caused by UV radiation.
Astaxantin has a unique ability to penetrate through a hematoencephalic barrier and a hematoophalmic barrier, which allows it to reach the retina and brain, providing protection against oxidative stress and inflammation.
Studies have shown that astaxantin can help improve vision, reduce eye fatigue and protect against EMD and cataracts. It can also help reduce intraocular pressure in people with glaucoma.
Good sources of Astaxantin include micro -crossbreaks Haematococcus pluvialis, salmon, shrimp, crabs and lobsters. Astaxantin is also available in the form of additives.
Bioflavonoids (flavonoids): strengthening capillaries and improving blood circulation
Bioflavonoids, also known as flavonoids, are a group of plant pigments with antioxidant and anti -inflammatory properties. They help strengthen the capillaries and improve blood circulation in the eyes, which is important to maintain the health of the retina and optic nerve.
Bioflavonoids can also help protect the eyes from damage caused by UV radiation and free radicals. They can reduce the risk of cataracts, VMD and diabetic retinopathy.
Good sources of bioflavonoids include fruits and vegetables of bright colors, such as berries, citrus fruits, apples, grapes, onions and green tea.
How to ensure sufficient consumption of vitamins for the health of the eyes
The optimal health of the eyes is achieved due to a balanced diet rich in fruits, vegetables, whole grain products and low -fat proteins. Include products rich in vitamins and antioxidants described above in your diet.
In some cases, it may be necessary to take vitamin additives to ensure sufficient consumption of certain nutrients, especially if you have certain diseases or restrictions in nutrition. However, it is important to consult a doctor or nutritionist before starting to take any additives to make sure that they are safe and suitable for you.
In addition to proper nutrition, do not forget about other important precautions to protect the eyes from the sun, such as the use of sunglasses with protection against UV radiation, carrying a hat with wide fields and avoiding staying in the sun in peak hours.
