MapcatSF Measures Macular Pigment
The protective macular pigment is a thin layer of yellowish tissue that lays directly in front of the macula region of the central retina. The macula is responsible for seeing fine details and colors. The macular pigment is very important for maintaining high-quality vision because it protects the central retina in two distinct ways.
First, the protective pigment blocks or absorbs damaging UV radiation from sunlight before it strikes the retina. Excessive UV radiation is now known to cause oxidative damage in the eye and studies show that excessive UV exposure is a significant risk factor for macular degeneration.
