The study has been published in the Journal of Food Science, published by the Institute of Food Technologists.
To reach the conclusion, authors from the University of Georgia compiled the results of multiple studies on the effects of the carotenoids lutein and zeaxanthin on visual performance. These carotenoids play an important role in human vision, including a positive impact on the retina.
After reviewing the various studies, the authors concluded that macular pigments, such as lutein and zeaxanthin do have an effect on visual performance. Lutein and zeaxanthin can reduce disability and discomfort from glare, enhance contrast, and reduce photostress recovery times. They can also reduce glare from light absorption and increase the visual range. "
