Did you know that every second a case of blindness is caused by lack of substances that are not synthesized by the body and are exclusively obtained with food?
Every moment the human body is faced with a variety of environmental factors. Light and sound affects us, temperature and humidity, the food that we eat and our way of life. Each body has its own function, and their “occupational hazard”. For example, the most negative factor to the eye is light. It does not matter if it is natural sunlight or artificial light.
Light is the Enemy
Any light is harmful to the eye: the light rays falling on the retina and destroying its photoreceptors, rods and cones. These special cells convert light into nerve impulses, which then goes to the brain, where visual images are formed. Since birth a person is given a huge strategic reserve of 7 million cones and 120 million rods, which allow him to see well both day and night. However, their number declines steadily under the influence of light that, over time, causes loss of vision and in some cases threatens with blindness.
Also, the rods and cones are destroyed by free radicals. These aggressive molecules are formed under the influence of bright light in the retina and lens. They cause a violation in capillary permeability, reducing the transparency of the lens and causing irreversible damage to the cells of the retina. Such “damage” can accumulate and cause a progressive decrease in visual acuity and the development of age-related changes in the eye (glaucoma, cataracts, and macular degeneration).
The formation of free radicals in the tissues of the eye occurs under the influence of constant exposure to light, regardless of what you are doing.
The mechanism of eye protection from damaging effects
No wonder nature has provided a mechanism for us to protect our eyes from the damaging effects of light rays. For the proper functioning of the antioxidant system of the eye there are responsible natural pigments carotenoids – lutein and zeaxanthin. They are accumulated in the retina and the lens, and create a natural filter that absorbs most harmful light rays such as ultraviolet.
Lutein is ingested with food only, but it is not synthesized in the body. Zeaxanthin is formed from lutein in the tissues of the eye. At first glance, every day you should have 5 mg lutein and 1 mg zeaxanthin. However, to provide such amounts of lutein from food you should consume at least a half-kilo of carrots, a pound of pepper, or about 250 grams of spinach. The daily diet is able to compensate for the almost one-third of the daily requirements of carotenoids, so nutraceutical supplementation is vital for maintaining healthy eyes.
How do you choose the right vitamin supplements for the eyes?
First, you must undergo a full vision examination. You can have this done at Boothe Eye Care Center where special equipment and the latest technology are used. Remember that only a specialist can determine which treatment you need your eyes. Dr. William Boothe has vast experience and he is always happy to help you correct your vision so you can see clearly.
