Did you know that one in two of blindness is caused by a lack of materials that can not be synthesized by the body and fed exclusively with food?
The human body every moment faced with a variety of environmental factors: affects us light and sound, temperature and humidity, the food we eat and the lifestyle that we choose. Each body has its own function and their "occupational hazard". For example, for the eyes as the most negative factor is light, it does not matter, it is about natural sunlight or an artificial light.
My light — my enemy
Any light is harmful to the eyes: falling on the retina, the light rays destroy it photoreceptors, rods and cones — special cells that convert light into nerve impulses, which are then fed to the brain, where visual images are formed. With the birth of a man given a huge strategic reserve of 7 million cones and 120 million rods can see well during the day and at night. However, when exposed to light steadily decreasing their number, which eventually causes deterioration of, and in some cases even threatens to blindness.
Destroys the rods and cones free radicals. These aggressive molecules are formed in the retina and the lens when exposed to bright light, they cause a breach of the permeability of capillaries, reducing the transparency of the lens and irreversible damage to the retina. Accumulating like "damage" caused a progressive decrease of visual acuity and the development of age-related changes in the eye (glaucoma, cataracts, macular degeneration).
The formation of free radicals in the tissues of the eye is exposed to light all the time, regardless of whether you enjoy the beauty of the landscape, enthusiastically reading a book or working at the computer.
Natural trap for light rays
Damage the eyes are not all the light rays, but only those that penetrate through light protective barrier. There is nothing surprising in the fact that the wise nature has provided a mechanism for protecting the eyes from the damaging effect of light rays, otherwise people would be literally doomed to blindness. Due to the natural system of protection of the most harmful blue-violet part of the spectrum of the light can not pass through light protective barrier, and free radicals are neutralized.
Responsible for the functioning of the antioxidant system of the eye-natural pigments carotenoids — lutein and zeaxanthin. They accumulate in the retina and the lens and create a natural filter which absorbs most harmful light rays — ultraviolet.
Visual cells to die of hunger?
Lutein is ingested with food only and are not synthesized in the body, and of zeaxanthin, lutein is produced in eye tissues. In various diseases of the eye, breaking the blood supply of the retina, lutein intake is broken, and its reserves in tissues of the eye are gradually reduced. It causes permanent visual impairment and blindness may result.
However vision may decline in healthy people when the body does not receive the required daily amount of lutein from foods. Supply of vital carotenoids for eye sooner or later exhausted, and his eyes are helpless in the face of "the enemy."
At first glance, every body needs nothing — some 5 mg lutein and 1 mg zeaxanthin. Nevertheless, to ensure delivery of the quantity of lutein to food should be consumed at least a half pounds of carrots, peppers pound or about 250 grams of spinach. Those whose eyes experience intense visual load, in reality, need to eat even more of these products, and the day-to-day.
One should also not forget that modern foods contain fewer nutrients than it was, say, half a century ago. The daily diet can compensate for almost one-third of the daily requirement in carotenoids, so nutraceutical supplementation is vital for maintaining eye health.
Vitamins for vision
The most important role of vitamins to maintain good vision has been proven recently: only at the end of the last century, scientists have discovered the key role of lutein and zeaxanthin for health eye. An increased need for lyuteinsoderzhaschih preparations have people older than 40 years, this is due to age-related decrease of protective functions and the body's ability to heal itself. At risk students and students with their higher visual load, especially those who already have eye problems.
How to choose their
The main criteria for selection of vitamins is effective and safe in recommended doses, confirmed by clinical trials. What matters is the quality of raw materials, it is only the use of standardized substances declared by the manufacturer guarantees the content of useful substances.
One available in pharmacies Russia is "Lutein complex". If it uses only natural substances standardized by the world's leading manufacturers. Unlike most drugs lyuteinsoderzhaschih "Lutein complex" contains only free lutein, manufactured by technology of microencapsulation. This ensures maximum absorption of the drug and allows him to maintain a high activity throughout the expiration date.
The structure of "Lutein Complex" also includes other beneficial for eye health ingredients — vitamins A, C and E, minerals, blueberry extract. Lutein protects the eyes from harmful free radicals and UV light, blueberry anthocyanins increase visual acuity, vitamins and minerals reduce eye fatigue, all the components of the drug enhances the effect of each other and reduce the risk of age-related changes in the eye.
For the prevention of visual impairment in school children developed "Lutein complex for children", which contains the optimum for a growing body of nutrients. "Lutein Complex childish" protects the retina and helps to eliminate all kinds of visual fatigue.
