Lutein, like zeaxanthin, is often referred to as an ""eye vitamin"" since it's a carotenoid pigment that's highly concentrated in the macula of the eye. As an antioxidant, lutein provides beneficial effects against oxidative stress from daily functions and environ pollutants. Lutein may also help reduce eye fatigue and strain related to blue light exposure from electronic devices and other age-related eye health changes. Why Choose Swanson Lutein dietary supplement?
