Carotenoid Lutein Protects Against Strong Light

Many vision scientists believe that sudden or repeated exposure to strong light, such as that from computer screens, causes more than just the temporary visual anomaly of “blue spots” floating in your vision. Researchers from Japan feel that such exposure triggers apoptosis (cell death) in photoreceptor cells and  thinning of the layer of photoreceptors cells at the back of the eye. In the Journal of Nutritional Biochemistry, the researchers concluded, “Although lutein has been applied as a dietary supplement to help prevent chronic diseases, such as AMD, it may have a chance to be involved as a preventative medicine that may assist acute diseases in the future”(1).


The role of carotenoids in general, and lutein (and its close relative zeaxanthin) in particular, in the preservation of eyesight has long been known to GNLD’s Scientific Advisory Board. When the initial formulation was made, the SAB standardised the whole food ingredients to assure that each capsule delivered the equivalent of a whole serving of lutein-rich foods. Today, this highly tested, frequently published, comprehensive, exclusive, and patented product (drawn completely from carrots, tomatoes, spinach, red bell pepper, peaches, strawberries, and apricots) continues to define the ultimate in whole food carotenoid supplementation.
