A healthy diet and exercises play an important role in eye health. Aging, infections, poor diet, wrong reading habits, excessive stress on eyes, lack of rest, and lack of exercise can affect your vision. Blurred vision, double vision, short sightedness, etc. are common vision problems. Chronic diseases like diabetes lead to impaired vision. Regular exercises, developing good reading habits, maintaining hygiene, offering sufficient rest to the eyes, and following a healthy diet help prevent vision problems. To maintain the health of your eyes, you need to provide all essential nutrients to the body. A nutrient-rich diet helps keep diseases at bay and ensures a healthy life.

Iron is essential for the formation of hemoglobin, which supplies oxygen to all cells and tissues. Lack of oxygen can damage your vision seriously. Thus, all these nutrients promote the functions of the body organs in several ways.
