Lutein is known as a carotenoid vitamin, one of the two major carotenoids that act as a color pigment in the macula and retina of your eye. It’s similar to other carotenoids like beta-carotene and vitamin A. If vitamin D is the “sunshine vitamin,” you can think of lutein as the “vision vitamin.” Scientists believe that lutein acts as a sort of natural light filter for your eye, helping to protect your vision from potential damage caused by ultraviolet sunlight, digital blue light from too much screen time and even a poor diet. Natural sources of lutein include brightly colored fruits and vegetables, including broccoli, spinach, kale, corn, peppers, kiwi, grapes, oranges, zucchini and squash.
