Zeaxanthin, Lutein May Help Protect Eyes Against UV Light Damage

The Calgary Herald /Monterey County Herald (5/26, Quinn) reported that, according to the National Eye Institute, eyesight is “all about light” entering the eye and hitting the retina. That body “contains ‘photoreceptors’ that convert light to electrical signals that travel to the brain and figure out what we ‘see.'” Unfortunately, ultraviolet (UV) light may damage eyes, much like it does skin. Fortunately, “specific nutrients and other substances in foods can help to absorb dangerous light and act as a shield.” The article went on to explain that vegetables and fruits containing zeaxanthin and lutein may help protect the eye against damage caused by ultraviolet light.
