Study: Leafy Green Veggies (2004) Protect Eyes
In the lab, researchers looked at the effects of lutein and zeaxanthin on samples of human eye lens cells. They compared the action of these antioxidants on the cells to that of vitamin E.
They treated the cells with concentrations of the antioxidants and then exposed them to ultraviolet radiation, about the same amount that a person gets with a mild tan.
Adding lutein and zeaxanthin to the cells reduced signs of ultraviolet damage by 50%-60%. Vitamin E reduced the same signs of damage by 25%-32%.
This study provides more evidence that these antioxidants found in plants such as spinach, kale, and collard greens, can help prevent cataracts by protecting the eyes from ultraviolet radiation.
