Lutein, zeaxanthin, and alpha-tocopherol may protect against cataract
Powerful antioxidants reduce DNA damage, peroxide levels and oxidative stress in recent study

In cataract, the lens of the eye clouds over, reducing vision. Oxidative stress is a factor in cataract, and hydrogen peroxide is the most common oxidant in this condition. Researchers incubated cultured human lens cells with lutein, zeaxanthin, or alpha-tocopherol for 48 hours, then exposed the cells to hydrogen peroxide for one hour. All three nutrients significantly reduced hydrogen peroxide levels, oxidative stress, DNA damage, and improved cell viability.
