Macular degeneration is now the #1 cause of blindness the United States. In fact, one in ten people over the age of 60 is affected and the incidence is growing. The macula is located near the center of the retina, which is the region of sharpest vision. The picture above shows what vision is like in someone affected by macular degeneration.
There are two types of macular degeneration: Dry and wet. Dry macular degeneration is caused by a steady deterioration or rotting away of the macula. Wet macular degeneration is caused by abnormal blood vessels that leak blood into the region of the macula creating scar tissue.
Two nutrients crucial for eye health are the carotenoids lutein and zeaxanthin. These compounds are more concentrated in the retina than any place else in the body. As people age, the levels of lutein and zeaxanthin go down, so it is crucial to make sure you are getting enough. The best sources are leafy greens like spinach, kale, turnip greens, collard greens, and romaine lettuce; broccoli; zucchini; peas; and Brussels sprouts.
