Lutein, Zeaxanthin (2008) and Light Sensitivity
Researchers have found that the carotenoids lutein and zeaxanthin which support the health of the eye are effective in the manner in which they help alleviate many vision problems such as good vision under glaring lights, which is related to the general sensitivity of the eye to bright light. Lutein and zeaxanthin were found to be markedly associated with improvements eyesight in glare conditions and the ability of the eye to recovery from the stress produced by such glare. Glare types include bright sunlight, computer monitar light, and car headlights at night.
The study included forty healthy people (mean age of 23.9) whose lutein and zeaxanthin levels were evaluated for six months. After six months of lutein and zeaxanthin supplementation, the levels of pigments in their maculas improved improved and they experienced a reduction in the harmful effects of glare.
