Paying close attention to your diet is essential to over all health, and focusing on a high intake of antioxidants has been linked not only to a reduced risks of cancer, but also to a reduction of eye disorders like macular degeneration and cataracts.

Avoiding unhealthy food is a lifestyle choice that will positively impact every part of your body, not just your eyes. It's okay to indulge your sweet tooth, and to eat unhealthy foods that you enjoy, as long as you pay attention to the amount you consume. Avoiding processed foods, foods containing high fructose corn syrup, and foods high in processed sugars will go a long way in helping ensure your overall health, and also help you to avoid health complications like diabetes that can lead to severe vision disorders.
