In general, I recommend that my patients include nutrient-rich foods such as fruits and vegetables as part of a healthy diet. A healthy lifestyle, consisting of balanced nutrition, moderate exercise, and appropriate rest is an important part of your overall health and well-being and can help prevent illness too.
The best way to ensure that you’re getting all of your essential vitamins and minerals is to eat a balanced diet that includes fruits and vegetables — they are a primary source of carotenoids, which can have overall benefits for vision health. Certain fruits and vegetables with higher vitamin A and C content have been shown to reduce glaucoma risk as well.
Some of the most helpful fruits and vegetables for healthy vision are:
- collard greens
- Brussels sprouts
- green beans
Because oxidative stress is associated with damage to the optic nerve in glaucoma, antioxidants may help to prevent further injury. Dietary sources of antioxidants include:
- acai berries
- dark chocolate
- black and green tea
- lycopene (from tomato products)
- dark green leafy vegetables like kale and spinach
- flax seeds
Any specific nutritional deficiencies in your diet can be addressed with supplements that include Vitamins A, B-complex, C, and E as well as the minerals Magnesium, Calcium and Zinc. However, there is no convincing data that vitamin supplements help to prevent glaucoma. I recommend that patients take a general multivitamin if they are uncertain whether their daily nutritional needs are met.
While good nutrition plays a role in disease prevention and overall health, it is not a treatment for glaucoma. Certain herbs such as ginkgo and bilberry may even increase the risk of bleeding with glaucoma surgery. Given the breadth of nutritional supplements available over-the-counter, it is important to discuss with your eye doctor all prescription, herbal, vitamin, mineral, and over-the-counter remedies you currently take.
Talk to your doctor about any other questions related to glaucoma and your diet, exercise, and lifestyle choices.
