Puritan’s Pride Lutein 20mg with Zeaxanthin 60 softgels

Even though they cannot be produced in the body, lutein and zeaxanthin from the diet are stored in the eyes. In fact, lutein and zeaxanthin are the only carotenoids found in appreciable levels in the macula. The macula is the area of the retina with a high concentration of specialized photoreceptor cells and is responsible for sharp focus on objects straight in front of you. With so much light entering the eye, and the cellular activity of sending these visual signals to the brain, the retina is an area of high oxidative stress.
