A study recently published in Optometry and Vision Science examined the effects of lutein and zeaxanthin in people with healthy vision. The purpose of the study was to supplement forty subjects with lutein and zeaxanthin for 6 months and determine if there was any effect in the subjects' response to glare. Various measurements were used and the researchers concluded visual performance after exposure to glare is improved with supplementation of lutein and zeaxanthin. Numerous studies have demonstrated the effects of carotenoids for vision health in patients with age-related macular degeneration, but this report notes these ingredients may also benefit those with healthy vision!
