Many ask, how does Zeaxanthin work. And the answer is very simple. Zeaxanthin works by creating a protective layer over the eyes which protect the eyes against the excessive sunlight. It not only protects but also enhances the way the macular pigment in the peripheral and central vision patterns work.
Studies have been performed by the Schepens Eye Institute and show that there is a great organization of the macular pigment, and that zeaxanthin and lutein are two of its carotenoids. However, zeaxanthin is the dominant component making up to 75% of the total composition, while in the peripheral retina, lutein is the most predominant, making up about 67%.
It's said that it's possible to increase its dosages by intaking the right dietary supplements. The study also pointed to the fact that there was a great decrease in the age-related macular degeneration known as AMD.
It's said that age-related macular degeneration is the main cause why people that are aged over 55 face blindness in western industrialized nations.
The best way to avoid these issues is for people that are aged above 55 to include in their daily diet vegetables and fruits of all sorts. These are a rich source of carotenoids such as zeaxanthin and lutein.
