Spinach, kale, collard greens, and other deep-colored vegetables
contain lutein and zeaxanthin, two carotenoids that “have been
associated with reducing the risk of developing cataracts and
macular degeneration,” says Emily Bedrick Graubart, an assistant
professor of ophthalmology at the Emory Eye Center and the Emory
University School of Medicine, in Atlanta. Try to eat two
servings a day―for example, a handful of spinach in your salad
at lunch and a side of broccoli at dinner.
