Nutritional Supplementation Helps Eyesight
Age-Related Macular Degeneration (AMD) is common with age, but can be avoided with proper nutrition.
A recent study published in the November 2011 Journal of Optometry confirms improved vision in elderly patients through nutritional supplementation. The Zeaxanthin and Visual Function Study (ZVF) conducted by Stuart Richer, PhD, OD, shows scientific evidence that dietary Zeaxanthin improved vision in night driving, fine detail, and in other areas.
The study followed 60 elderly veterans with early AMD who consumed 8 mg daily of dietary Zeaxanthin over a 12-month period. The participants showed improvement of 1.5 lines or 8.5 letters on a standard eye chart, and noticed a disappearance of blind spots.
Early symptoms of AMD include difficulty driving at night, reading in low light, blind spots, and loss of vivid colors.
Zeaxanthin specifically protects the cones, or photoreceptors responsible for central vision, color perception, and fine detail. While Zeaxanthin and Lutein are found in brightly colored fruits and vegetables as well as dark green, leafy vegetables, Zeaxanthin is scarce in the average U.S. daily diet, making it difficult to maintain healthy macular pigment levels to protect and enhance vision.
