What is MPOD? Macular pigment is comprised of Zeaxanthin and Lutein, which are found in the center of the macula (fovea) at a natural 2:1 ratio. MPOD (Macular Pigment Optical Density) is important for three specific reasons: 1. Low macular pigment is a key risk factor for Age-related Macular Degeneration (AMD), the leading cause of significant vision loss over age 55 2. Macular pigment absorbs harmful blue light, protecting the photo-receptors from damage 3. Macular pigment improves visual performance, including: Visual acuity – ability to see clearly, especially in fine detail situations like needlepoint or reading in low light situations. Contrast sensitivity – ability to discern objects from their background (i.e. seeing a white golf ball or baseball clearly against a light blue sky). Light sensitivity – visual discomfort in sunlight or when exposed to bright light. Glare recovery – recovery from temporary “blindness” caused by high intensity lighting, such as automobiles or stadium lights.
