Avoid exposing your eyes to bright light for a long period of time. The bright light can cause your eye muscles to strain. They can also damage your eyes. If you are out in the sun all day long, wear a hat and a pair of sunglasses that offer UV protection.
Drink plenty of water to keep your eyes hydrated. Your eyes are made mostly of water, and they need to stay moist at all times to remain healthy. Dry eyes are more prone to eye problems and diseases. Keeping your body fully hydrated will ensure that your eyes stay moisturized.
Eat foods that are known to promote good eye health. This includes a variety of leafy green vegetables, such as collards, kale and spinach. Citrus fruits provide vitamin C, which can help to maintain your eyesight. In addition, protein sources such as beans, eggs, and lentils can prove beneficial to your eyes.
