Imagine having a black spot or a blur in the middle of your vision. That's what people with macular degeneration (MD) see. MD is a progressive eye disease that causes the cells in the macula to die. The macula is where your eye absorbs details of what you see. MD destroys the vision you need for watching television, driving, reading and seeing a face. The person with MD can gradually lose central vision, but still has peripheral (side) vision.
The disease affects 15 million Americans, making it the leading cause of vision loss. Those numbers are expected to climb as baby boomers enter their 60s. About 14 percent to 24 percent of Americans between the ages of 65 and 74, and 35 percent who are 75 and older, will have age-related macular degeneration (AMD), according to the Macular Degeneration Partnership.
Be aware that herbs and supplements are not strictly regulated by the Food and Drug Administration. Do not assume if a product is considered "natural" that it is harmless. Many substances do not have sound science behind them to prove their safety or how well they work. Manufacturers may not be giving you what you think you are getting, or the way the substance is processed may be unhealthy or unsafe.
With many of these products, doctors do not know enough about them. Herbs and supplements may interact with prescription and over-the-counter medications or can worsen your health conditions. Consider that some supplements, such as vitamin A, may be unsafe when taken in mega doses.
It is strongly advised that you talk to your doctor before taking any supplement or herb. If you are taking an herb or supplement and notice any unusual symptoms, stop taking the substance immediately and talk to your doctor.

What the experts say |
| Lutein |
Prevents or delays macular degeneration. |
This is considered safe if you take it according to recommended doses. No one knows how much is too much or the dangers of high doses. To date, no side effects have been reported. |
Evidence does suggest people with macular degeneration have small improvements with the use of lutein. Strong evidence says lutein can keep your eyes healthy. However, there is no evidence that says lutein can reduce the risk of macular degeneration or other age-related diseases. No one knows how much is too much. Your best bet is to get lutein from foods such as corn, egg yolks, spinach, kale, romaine lettuce, peas, leeks and collard greens. |
