Lutein for Eyes: What the Research Says
The best evidence for lutein comes from the AREDS2 study, which used 10 mg of lutein and 2 mg of zeaxanthin in a formula for people with intermediate age-related macular degeneration (AMD). It slowed progression to advanced AMD in that group, but it has not been shown to prevent AMD or cataracts in people without the disease.

Lutein from food
Lutein is found in leafy greens like kale and spinach, and in egg yolks. A varied diet is a good base for overall eye health.
Comparing supplements
When you look at any eye supplement, check whether the label lists exact doses. Products that only list blend names, such as Retina Clear, cannot be compared directly with the AREDS2 amounts. Ask your eye doctor before starting a supplement, especially if you take medication.
