The eyes are an incredibly delicate part of the human body that need to be cared for in order to function at optimal efficiency. Without adequate nutrition, your eyes could become damaged or experience poor vision. While any part of the body will suffer if you don't take good care of it, the eyes are particularly vulnerable. Read on to learn about the three main parts of the eye that need good nutrition to thrive.

Nerves

The nerves of your eye are complex and perform a wide variety of tasks. The nerves send signals through the eyes and to your brain in order to allow you to see. In addition, they also help you to feel when something's going wrong with your eyes, such as if they're itchy or painful or if there's a foreign body on the surface of your eye.

If the nerves in your eye degrade, you could potentially experience poorer vision or even total blindness. As such, you should do everything you can to help maintain the health of the nerves in your eye. There are many supplements out there that support nerve health, so if you have a poor diet, it's a good idea to boost your body's nutrition with one or more of them.

Blood Vessels

The blood vessels are not only responsible for sending blood into the eye, but they can also have a significant impact on your vision. When blood vessels are affected by diseases like diabetes, the narrowing or inflammation of the blood vessels can cause problems like retina damage. An increase in blood pressure can potentially damage the blood vessels in your retina, leading to this problem. Therefore, keeping high blood pressure in check is critical to maintaining your vision.

Surface

The simplest part of your eye that requires good nutrition is the surface of the eye. With inadequate fluid intake, you can experience dry eyes, which can itch and make your vision blur. In addition, you're far more likely to rub your eyes if they're itchy or blurry. Rubbing your eyes can potentially damage the surface of your eye. Thankfully, drinking enough water and taking supplements like fish oil can help to reduce dry eye symptoms.

With this information on-hand, you can help to promote the health of your eyes by ensuring that you're getting adequate nutrition. Talk to an eye doctor to learn more about eye care supplements that could help you.
