Reading a menu, spotting a grandchild's face across the room, driving home at dusk. Sharp central vision does a lot of quiet work every day.
What it may do for you
Lutein and zeaxanthin are plant pigments. They collect in the retina, the light-sensitive layer at the back of your eye, and in the lens. The National Eye Institute says they may help absorb harsh blue and ultraviolet light, a bit like sunglasses built into the eye.
Leafy greens are a good source of both. The same institute notes that earlier studies suggested people who ate diets rich in green, leafy vegetables had a lower risk of age-related macular degeneration, or AMD. AMD is an eye disease that blurs central vision and can make faces, reading and driving harder, and the institute lists leafy greens and fish among the healthy foods that may help lower risk.
What about pills? AREDS2 was a large trial of 4,203 people ages 50 to 85 who already had intermediate AMD. Those who gained the most from lutein and zeaxanthin supplements ate little of them in their food. In that group, the risk of advanced AMD was 26% lower. The institute also says these supplements do not prevent AMD from starting.

Good to know
The AREDS2 supplements were tested in people who already had intermediate AMD. Ask your eye doctor whether a supplement makes sense for you, if any. If you take a blood thinner such as warfarin, talk with your doctor before changing how many greens you eat.
