Are carrots the key to a better eyesight?

FOX's Dr. Sapna Parikh addresses that theory in this "Housecall for Health":

This is Housecall for Health.

If you eat carrots, will it really improve your eyesight? Chances are you've heard that at some point, but is there any truth to it?

Well the answer partly depends on your nutritional status is to begin with. Carrots are thought to be beneficial because of they contain beta carotene which your body converts to Vitamin-A. 

Vitamin-A does play a role in vision, especially night vision. It's thought to help the eye convert incoming light into a signal that's transmitted to the brain, so you can see in low light.

For people in developing parts of the world who are undernourished, research shows that Vitamin-A supplements do improve vision. In fact, according to Scientific American, up to half a million children in those areas may become blind because of a Vitamin-A deficiency.

But for most of us living in developed countries like the U.S., we already get enough Vitamin-A. Consuming more carrots or other Vitamin-A containing foods may help protect your vision, but it's not gonna make a huge difference.
