Light and images travel into the eye through the pupil, finally focusing on the internal wall of the eye, known as the retina. The center area of the retina that provides the details of vision that allow us to read and distinguish facial features is known as the macula.

As we age, the macula inside our eyes is vulnerable to degenerative changes that can affect our ability to see these precious details. The condition is called Age Related Macular Degeneration (AMD), and it is the most common cause of irreversible blindness in the Western Hemisphere.

The early forms of this condition are called “dry” or atrophic macular degeneration. Although not usually rapidly progressive, it can cause severe vision loss. Some patients  progress to “wet” or exudative macular degeneration, in which there is bleeding beneath the retina with rapidly progressive vision loss.

Research by the National Eye Institute demonstrated that high-dose nutritional supplementation with large quantities of antioxidants can slow the progression of macular degeneration. And more recent research has shown that large quantities of lutein and zeaxanthin can improve vision and the appearance of the retina in macular degeneration.*
