The Importance of Carotenoids
Macular pigment in the eye is composed of the three macular carotenoids with meso-zeaxanthin in the central retina. The pigment is able to filter damaging visible, or blue, light and protect against oxidative stress which can lead to eye diseases such as Age-related Macular Degeneration.

Healthy macular pigment is also important for optimal vision and for those dependent upon first class vision for their professions or sporting lives.
