Dietary Supplements May Improve Visual Function

Visual performance in normal eyes can be affected by macular pigments such as lutein and zeaxanthin.  In a study published in the Journal of Food Science in December 2009, the investigators reported that these carotenoids can help to stave off glare and quicken the time a person’s eyes recover after being exposed to blinding flashes, such as oncoming headlights. According to the lead author Billy Hammond PhD, professor of neuroscience at the University of Georgia, these two carotenoids play a role in how fast the brain processes information.  He also noted that people vary dramatically in how much of these pigments they have. Dr Hammond notes that carotenoids are going to play an important role in the maturation of the visual system in babies and may play a crucial role in cognitive function also.  “The retina is a neural tissue and reflects neural tissue in other parts of the body like the brain,” he said.  This may play a role in future research in diseases such as Alzheimer’s. Dr Ashraf of the Atlanta Vision Institute adds, “that by supplementing your diet with these carotenoids may not only help with prevention of macular degeneration but may also improve cognitive function.”
