Although eating a well-balanced diet can help maintain eye health for many people, recent studies have pointed to specific vitamins, minerals and other substances as being good for the eyes.
Vitamins
Vitamins A, C and E have been found to be important in eye health; vitamin A is vital for the retina, and some think vitamin C may play a role in preventing glaucoma--although it is not a cure or a treatment.
Minerals
Minerals such as zinc are important for eye health by reducing the risk of advanced macular degeneration; selenium is also important.
Carotenoids
Carotenoids such as lutein and zeaxanthin are found in large amounts in different parts of the eye and protect the eye from damage from free radicals and blue light.
Bioflavonoids
Bioflavonoids are plant compounds that have been found to prevent the development of cataracts and may slow down the development of glaucoma.
Fatty Acids
Omega-3 fatty acids such as DHA have been found to lower the risk of age-related macular degeneration; consuming more fish, nuts or olive oil can be protective.
Considerations
With these vitamins and minerals, one must make sure not to take too much which can have adverse effects. A multivitamin supplement is often enough; before starting on any medication, be sure to consult a physician.
