The eyes are the human senses are very important / essential. Conceivably, if we suffered eye damage or blindness, we can not enjoy and feel how beautiful the universe.
In fact we often forget to make eye care, but as well as other parts of the body, the eyes may be affected by disruption or health problems. Disorders-disorders can be caused by air that is not clean or polluted, solar radiation, radiation from too long at the computer, and other disorders.
Studies conducted by the Eye Disease Prevalence Research Group (2004) estimates that by 2020 the number of patients with eye disease and blindness in the world will reach 55 million. This study also mentions that the eye disease and blindness will increase, especially for those who have aged over 65 years. A person aged 80 years and over who constitute 8% of the total population, suffered blindness as much as 69%.
Health problems in a common eye is a decrease in visual function, symptoms of red eyes without any loss of visual function, and red eye with visual function down. Until now, the eye disease that affects many are cataracts, glaucoma and infections.
Along with the increased attention and knowledge of the effect of nutrition on health, especially the health of the eye cause the rapid growth of the market for health products, food medicine, health food, health drugs, dietary supplements, health supplements, herbal remedies, natural cures eye. Most of the products for the health of the eye which is currently marketed in the form of supplements, food medicine, health food, health drugs, dietary supplements, health supplements, herbal medicine, natural medicine. In addition to antioxidants (vitamins A, C, and E) that has previously been known to improve eye health, other compounds such as lutein, zeaxanthin, and astaxanthin, was recently identified as a compound that can improve the health of the eye.
Lutein is a yellow carotenoid class of compounds commonly found in leafy green vegetables. Lutein found in the macula and is believed to protect the eye from oxidative damage by ultraviolet radiation (UV).
Macula is located in the center of the retina and directly adjacent to the eyepiece. Macula is a small area that contains millions of cells that help produce sharp vision to read or see objects clearly.
Another carotenoid compounds contained in the macula is is zeaxanthin, which are known to provide benefits for eye health.
Research conducted by Chitchumroonchokchai and colleagues in 2004 from Ohio State University, showed that lutein and zeaxanthin may protect the human lens cells from UV exposure, which is a major cause of cataracts. In addition, they compared the antioxidant activity of lutein and zeaxanthin as vitamin E. The results show that lutein and zeaxanthin showed activity 10 times higher than vitamin E in protecting the lens cells from damage caused by ultraviolet light.
In the same year, also conducted research by Neuringer and colleagues, demonstrated the ability of lutein and zeaxanthin in eye health. While testing in animals, sponsored by DSM Nutritional Products of Switzerland, showed that supplementation or addition of lutein and zeaxanthin boost antioxidant activity in the blood.
A group of other carotenoid compounds that actually has the ability to protect the macula from UV exposure is astaxanthin. Guerin et al. (2003) mentions that the ability of antioxidant and anti-inflammatory compounds astaxanthin can provide eye protection from UV rays.
Until now, the antioxidant activity of the compounds lutein, zeaxanthin, and astaxanthin provide answers mechanism of the increase eye health. Free radicals from UV light or air pollution, into the eye resulted in oxidation of molecules susceptible to the lens of the eye.
So that the eyes can be maintained his health, it helps us perform eye health care tips below:

Recent studies show that vitamin and antioxidant group can prevent, or at least slow the growth of macular degeneration and cataracts. Good nutrition for the body is also good for the eyes.
4. Use sufficient light.
Working with minimal light can cause eye fatigue, but the light is too bright, too bad. Best light direction when working on the computer is on a soft light table lamp from the side.
