There are many reasons for vision loss from premature aging of the retina and lens. Lutein and Zeaxanthin were identified in 1995 as the only two Carotenoid antioxidants specific to lens and macula health.
Selectively accumulated from plasma and deposited in the lens, macula, and lungs, these two Carotenoid antioxidants filter light and protect the retina.
The macular pigment, composed of Lutein and Zeaxanthin, functions as a colour filter to protect the light-sensitive photoreceptor cells (responsible for visual acuity) from ultraviolet-light-originated free radical damage. Recent studies have shown an even greater need for Zeaxanthin and so we have now increased the content to the highest available.
