Lutein And Zeaxanthin Intake Is Inversely Related To The Risk For Senile Cataract

Molecular Vision: Lutein and zeaxanthin supplementation reduces H2O2-induced oxidative damage in human lens epithelial cells:

Epidemiological studies suggest that dietary intake of lutein and zeaxanthin is inversely related to the risk for senile cataract.

Conclusions: These data indicate that lutein or zeaxanthin supplementation protects lens protein,
lipid, and DNA from oxidative damage and improves intracellular
redox status upon oxidative stress. The protective effects are
comparable to that of α-tocopherol, except that lutein and
zeaxanthin cannot compensate for GSH depletion. The data imply
that sufficient intake of lutein and zeaxanthin may reduce the
risk for senile cataract via protecting the lens from oxidative
damage.
