Eye Conditions

Eye conditions that can lead to permanent visual impairment or blindness—including age-related macular degeneration (AMD), cataract, diabetic retinopathy, and glaucoma—are serious public health problems. Researchers are working to find better ways to prevent and treat these conditions, including the use of dietary supplements.

Bottom Line: Supplements containing antioxidants and zinc have been shown to reduce the likelihood that AMD will progress to the advanced stage in people who already have the intermediate stage of this disease. However, no dietary supplements have been shown to help prevent or treat cataracts, glaucoma, or diabetic retinopathy.

Safety:

  • Don’t replace scientifically proven medical treatments for an eye condition with dietary supplements that are unproven. To preserve your vision, it is very important to follow the prescribed treatment for your eye condition.
  • “Natural” does not necessarily mean “safe.” Learn more about the safety of dietary supplements.
