Healthy Eating and Healthy Eyes - Why Your Diet Matters for Eye Health

When people think about eating healthy, they often focus on heart health, weight management, or overall wellness. But your diet also plays a huge role in protecting your eyes. The foods you eat supply essential nutrients that help maintain good vision, reduce the risk of eye diseases, and support overall eye function.

Just like the rest of your body, your eyes need the right balance of vitamins, minerals, and antioxidants to stay strong. A nutrient-rich diet can protect against conditions such as age-related macular degeneration (AMD), cataracts, and even dry eye.
