What is macular pigment made of?
The most potent of the three antioxidants. It is found at the very center of the macula, the fovea, which is the epicenter of our central vision. This part of the eye has the highest density of photoreceptors (cones) and the highest light exposure. Therefore, the tissue at the most risk is protected by the strongest of the three antioxidants. Studies have shown that supplementation with Meso-Zeaxanthin has resulted in increased levels of macular pigment optical density.
The protective role of lutein in the eye stems from its ability to filter short wavelengths of visible blue light, function as an antioxidant and stabilize membrane integrity. These functions are believed to play an important role in reducing light-induced oxidative damage which can lead to age-related degenerative disease such as age-related macular degeneration and cataract.
The role played by the powerful antioxidant zeaxanthin in the eye is to sharpen central vision (the clearness with which objects stand out from their surroundings), reduce the effects of glare (blue light) and maintain healthy visual acuity. Zeaxanthin is also found in the brain and other organs. Zeaxanthin along with Meso-Zeaxanthin protects retinal tissue by absorbing similar wavelengths of high energy light.
