Prevention of Eye deseases

Eye Disease Prevention
How do sunglasses help prevent eye diseases?
Sunglasses protect the sensitive skin surrounding the eyes from sun damage that can lead to skin cancers such as carcinoma or melanoma. They also protect the cornea health as well as the lens of your eyes where cataracts form. It is recommended that you always wear a quality, professionally fit pair of sunglasses and a wide brim hat while you are outdoors.
Questions and Answers About Your Eye Health and Nutrition.
Q. Can vitamins help keep eyes healthy?
A. YES. The antioxidant vitamins A, C, E, and Beta Carotene, and the B-complex vitamins are particularly important. Even a slight deficiency of Vitamin A can cause tired eyes, sensitivity to light variations, dry eyelids and increased susceptibility to infection. Chronic to severe deficiencies can result in ulceration and distortion of the cornea and even blindness. Vitamin A is essential for the formation of visual purple necessary for night vision. B-Complex deficiencies can result in light sensitivity, paralyzed eye muscles, itching, burning, blood shot, and watering eyes. Pantothenic acid (B5) is particularly important for eye stress. Thiamin (B 1) is important for eye metabolism. Riboflavin (B2) has been linked to preventing cataracts.
Q. Can minerals help to keep eyes healthy?
A. YES. Minerals are important too, particularly Zinc and Selenium. Zinc concentration in the human retina is higher than in any other organ. Supplemental zinc has been shown to slow down the progression of macular degeneration. Low Zinc levels are associated with increased risk of cataracts. Both Zinc and vitamin A improve night vision.

Q. Do eyes need amino acids too?
A. YES. The amino acids Glutathione and Taurine are particularly important. Glutathione is found at a very high concentrations in the lens. Reduced levels are found in virtually all forms of cataracts. Glutathione functions as an antioxidant, participates in amino acid and mineral transport, and protects the lens of the eye from destructive effects of ultraviolet light.
Q. What is Lutein and how can it improve eye health?
A. Lutein is a Carotenoid found in foods such as broccoli, collard greens, kale, mustard greens, and spinach. Lutein and its isomer Zeaxanthin are concentrated in the retinal macular pigment and are the only Carotenoids presents in the human lens. Several studies have shown that a high intake of these Carotenoids have been associated with a reduced risk of both cataracts and macular degeneration.

Q. Are there any herbs that support eye health?
A. Yes. The chemical constituents of several herbs have demonstrated positive effects on eye health. Clinical studies with Bilberry have confirmed positive results in macular degeneration, cataracts, retinitis pigmentosa, diabetic retinopathy and night blindness. Ginkgo Biloba has demonstrated impressive results in the treatment of macular degeneration. Eyebright is used to strengthen eye tissues and provide elasticity to the optic nerve, which is responsible for sending what we see with our eye to the brain for processing.
Q. Can poor nutrition damage eyes and cause vision problems?
A. Definitely. While a deficiency of even one nutrient can cause vision problems, the risk of cataract, macular degeneration, and other vision problems is most significant when several nutrients are low in the diet.

Q. Can vision be improved or even restored with good nutrition?
A. Yes. According to several studies, loss of vision can be improved when optimum nutrient levels are restored:
Over 40% of patients who regularly took supplements containing vitamins such as B2, C, E, and Beta-Carotene combined with Copper, Manganese, and Selenium were able to improve their vision.
Cataract regression was seen in patients treated with vitamins E, B2, and B6 and their vision improved.
Eye disease was retarded in 70% of nearly 1,000 patients with age-related macular degeneration or diabetic retinopathy, who were treated with vitamins A, C, E, and selenium.
