Medical Wellness VISION - For Aging Eyesight
(MDW-VisionF)
| Medical Wellness VISION helps provide the essential nutrients that your eyes must have. VISION helps those with eyesight problems associated with getting old, e.g., aging macular degeneration, cataracts and more. The effectiveness and safety of VISION nutrients has been reported in major medical journals as helping to increase the blood circulation in the optic nerve and retina and thus improving eyesight. |

Losing one's eyesight from aging can be avoided if caught in time. Blindness is permanent. The most common causes of vision loss in older adults are cataracts and age-related macular degeneration. By the age of 65, over 30% of Americans suffer from severe vision problems that are not correctable with glasses or contact lenses.
Those with the greatest risk for age-related macular degeneration (AMD) tend to have a lower amount of Lutein and Zeaxanthin in the eyes than those without AMD. A large epidemiological study reported that increased consumption of Lutein and Zeaxanthin reduces the risk of AMD. Another later study agreed, showing that Lutein supplementation increases macular pigment. This is important because macular pigment can protect against AMD. Some observational studies have shown that generous intakes of Lutein and Zeaxanthin, particularly from certain xanthophyll-rich foods like spinach, broccoli, and eggs, are associated with a significant reduction in the risk for cataract (up to 20 percent) and for age-related macular degeneration (up to 40 percent).
 Cataracts are the leading cause of vision impairment in the United States and other developed countries. In cataracts, the lens of the eye, which is normally colorless and clear, grows cloudy. The lens is then unable to focus accurately of the retina, which makes seeing more difficult.
There have been three epidemiological studies looking at the correlation between dietary Lutein and Zeaxanthin and the risk of cataracts. These found a trend toward reduced risk of cataracts and cataract surgery with increased intake of
Lutein and Zeaxanthin.
Lutein and Zeaxanthin can help protect vision by guarding against both cataracts and ARMD. These safe, beneficial compounds are chemically classified as carotenoids, the naturally occurring pigments found in many colorful fruits and vegetables.
Lutein and Zeaxanthin absorb near-to-UV blue light, which has the highest energy and is therefore the wavelength most potentially damaging to the retina and macula. Second, Lutein and Zeaxanthin are potent antioxidants that quash the formation of free radicals. By causing damage in both the lens and macula, free radicals may contribute to both cataracts and ARMD.
A solid body of scientific evidence points to the great potential of Lutein and Zeaxanthin in combating cataracts and ARMD. Three studies showed that men and women with a high intake of Lutein and Zeaxanthin had significantly lower risks of developing cataracts compared to those with a low intake of these carotenoids.
The formation of cataracts is in part due to oxidative damage. Research has shown that antioxidants such as Lutein and Vitamins A, C and E do help counter the destructive effects of cataracts.
In the well-known Beaver Dam Eye Study, scientists examined the relationship between dietary intake of antioxidant nutrients and the incidence of cataract formation in adults aged 43-84. Those who consumed foods that are high in anti-oxidant vitamins had a diminished risk of developing cataracts. This study is consistent with the protection of Lutein and Vitamins A, C and E on the development of cataracts.
Other studies agree that Vitamin A helps protect against cataracts. For example, in the Nurse's Health Study, researchers followed 50,828 women, aged 45-67, for eight years. Women who consumed the most Vitamin A had a 39% lower risk of developing cataracts than women who consumed the least Vitamin A.
Ancient Chinese medical manuscripts indicate that for at least 5,000 years, the leaves of the Ginkgo tree have been used for various health conditions, including supporting circulation, cognition, and respiratory function. Exciting new findings suggest that Ginkgo may also hold promise in countering ARMD. German researchers recently conducted a controlled, double-blind study of human subjects suffering from the dry form of ARMD. The subjects who used Ginkgo showed marked improvement in their vision.
DHA is also the major fat in retinal tissue. It plays a strong role in the photoreceptor cells of the retina, suggesting an essential role for DHA in vision. DHA deficiency in laboratory animals shows a marked decrease in proper functioning of the visual cycle.
In a recent study looking at fish oil, which contains DHA, and macular degeneration, researchers found that more frequent consumption of fish appears to protect against late age-related macular degeneration.
In addition to DHA, Bilberry (Vaccinium Myrtillus) is good support for a healthy nervous system. It is closely related to American blueberry, cranberry, and huckleberry. During the Second World War, British and American fighter pilots hailed Bilberry jam as a secret weapon for improved night vision.
Bilberry extracts are rich in a chemical known as anthocyanoside. These chemicals are powerful antioxidants that appear to have a special affinity for the eyes. Bilberry's effect may also be related to increased generation of rhodopsin, a purple pigment essential for helping the eye adapt to light and dark. Bilberry appears especially useful in reducing eyestrain and improving night vision.
Bilberry was investigated for its effect on vision acuity in dim light and in night vision in normal subjects, on the progression of cataracts, and on patients with pigmentary retinitis (a hereditary disorder that affects night and peripheral vision), hemeralopia (diminished vision in bright light), macular degeneration, diabetic retinopathy, and retinal inflammation.
Lutein and Zeaxanthin carotenoids found in green, leafy vegetables, are also good for the eyes. Like other carotenoids, they are antioxidants. Recent studies have found that diets rich in Lutein and Zeaxanthin play a role in reducing the risk of age-related macular degeneration and cataracts.
Alpha-lipoic Acid (LA) also known as Thioctic Acid, is a naturally occurring compound that is synthesized in small amounts by plants and animals, including humans. The antioxidants Vitamin E and Alppha-lipoic Acid slow the loss of sight from retinitis pigmentosa in mouse models, evidence linking antioxidants to improved eye health.
Alpha-lipoic Acid can significantly reduce diabetic cataract formation, as well as neuropathy, and can be an ideal neuroprotective substance in the treatment of all oxidative brain and neural disorders involving free radical processes.
