Lutein Lutein is a member of the carotenoid family. Its yellow/orange tint is found in green leafy vegetables such as spinach, collards, cabbage, tomatoes, as well as in the yolk of eggs. By eating just five servings of lutein-rich foods per week, you protect your vision from future deterioration.
Lutein protects your vision in two ways: By acting like a soldier, attacking free radicals, protecting your vision from cataracts and by acting like a filter, filtering out dangerous blue tints, preventing macular degeneration.
Vitamin C This vitamin stops cataracts from progressing as well as from forming. The most well known source of vitamin C is the orange. Vitamin C is also found in fruits and vegetables, such as broccoli, grapefruit, tomatoes, cantaloupe, peppers, and cabbage.
Best known for preventing scurvy and treating colds, vitamin C is also a protector. Like lutein, vitamin C attacks free radicals. Recent studies show that a diet high in Vitamin C may reverse the onset of cataracts, preventing future cloudiness.

Absence of zinc has long been associated with poor night vision. Now, zinc has been linked to protecting you from macular degeneration. And if fate has already stepped in, zinc may slow further deterioration.
