Intense eye strain - the cause of vision loss
A person receives the lion's share of all information about the world around him through his eyesight. But do we protect our eyes?
The lion's share of all information about the world around people gets through vision. But do we take care of our eyes? We read in shaky transport and in poor lighting, spend hours sitting in front of a TV screen or a computer monitor, do not follow the day and diet, save on sunglasses and forgettable drops for the eyes. All this, of course, does not help to maintain good vision.
Why does my vision go bad?
Evolutionarily, our eyes are adapted to see in reflected light: there were no direct sources of intense light (except the sun) in the past, and looking at the sun is not a pleasant occupation. However, every year there are more and more artificial sources of direct light. Artificial light attacks the eyes from all sides: these are advertising signs shimmering in all colors of the rainbow, and the light of car headlights, and the lights of discos, and fluorescent energy-saving lamps.
Intense light rays cause the formation of a huge amount of free radicals in the tissues of the eyes. These ubiquitous, aggressive molecules are not visible to the naked eye, but they are the cause of today's age-related diseases such as age-related macular degeneration, cataracts and glaucoma. Damaging everything in its path, free radicals destroy cones and rods, disrupt the permeability of the vessels of the eyes, and reduce the transparency of the eye lens (lens). These factors cause progressive visual impairment and can cause blindness.
Natural eye protection
Nature took care of protecting such an organ that is so important for humans and created special biologically active substances - carotenoids, which provide natural antioxidant protection against the damaging effects of free radicals. Of the many hundreds of carotenoids currently known in the eye, only two have been discovered - lutein and zeaxanthin. They neutralize free radical molecules, protect the eyes from the phototoxic effects of intense light, and help repair damaged cells. In addition, lutein and zeaxanthin form a powerful natural filter that absorbs aggressive rays of the blue-violet spectrum (there are especially many such rays in bright artificial light).
In the body, lutein is not synthesized, in order to maintain eye health, we need regular replenishment of its reserves. Zeaxanthin is an isomer of lutein and is formed directly in the tissues of the eye. Despite the fact that every day we need only 5 mg of lutein and 1 mg of zeaxanthin, a normal diet is not able to satisfy this need, even by a third. Theoretically, it is possible to provide the right amount of lutein only due to its intake with food, but is it easy to eat a kilogram of carrots, a kilogram of bell pepper or 250 grams of spinach daily? The question, of course, is rhetorical.
Effective Eye CareNutraceuticals with lutein have been created to help the eyes, tired of exorbitant visual loads. In addition to lutein, these extremely useful natural preparations include vitamins, minerals and other substances important to eye health. On the domestic market there are about two dozen different drugs containing lutein in various forms and dosages. When choosing a drug, special attention should be paid to its effectiveness, bioavailability and safety in the recommended dosage. Most modern drugs contain lutein in the form of an ether, for the good assimilation of which requires the participation of specific enzymes, as well as the consumption of large amounts of fatty foods. At the same time, free lutein is easily absorbed unchanged and is twice as active as lutein in the form of ether.
