Age-related Macular Degeneration Linked To Low Antioxidant Levels And Sunlight Exposure
"Some types of the age-related macular degeneration (AMD) have been linked to low plasma levels of antioxidants and blue light exposure from the sun, according to researchers from Europe who published a paper in the October issue of Archives of Ophthalmology.
"The retina is vulnerable to the damaging effects of light," write author Astrid E. Fletcher, Ph.D. (London School of Hygiene & Tropical Medicine) and colleagues. "While wavelengths in the UV radiation range are largely absorbed by the cornea and lens, the retina is exposed to visible light, including blue light." According to previous animal and laboratory studies, it is possible that blue light can damage the retina and lead to a deterioration of the area of the retina responsible for sharp vision (the macula); this is called AMD...
...The researchers recommend that people consume key antioxidants by ingesting appropriate amounts of vitamin C, zinc, and carotenoid-rich fruits and vegetables. Further, they reiterate the standard precaution of wearing broad-rimmed hats and sunglasses to reduce the exposure of the retina to blue light."
