Extensive research in the Age-Related Eye Disease Studies (AREDS2), discovered that macular degeneration can be slowed in people who are at high risk for vision loss due to macular degeneration by taking supplements containing vitamins C and E, lutein, zeaxanthin, zinc and copper. Some of these vitamins can be found in certain foods.. For example lutein and zeaxanthin can be found in dark green, leafy vegetables like spinach and broccoli, and zinc can be found in beef, milk and whole grains. Please consult your doctor to find out if these vitamins may be helpful for you.
