A Carrot a Day Keeps the Eye Doctor Away

You've probably heard growing up that carrots improve your vision, but more often that not, that's a myth! This myth started in World War II, but the truth is, no matter how many carrots you eat, it isn't going to reverse bad eyesight. However, the Vitamin A that's in carrots does play an essential part in your vision.

When you eat Vitamin A, it is stored in your liver in the form of retinal. The retinal is then transported all the way through your body to your eyes. Your eyes have receptors that the retinal attaches to and when the retinal receptors in your eye absorb any light, the retinal undergoes photoisomerization. Photoisomerization is when light causes a molecule to changes shapes. Once the retinal undergoes photoisomerization, it can finally activate your photoreceptors. Photoreceptors are very important because they are in charge of initiating your vision. Retinal is also necessary for the continuity of vision. If you don't get enough Vitamin A, you'll end up having a retinal deficiency, and the first type of vision that goes is your night vision.

Vitamin A is not only found in carrots; it is also found in plenty of other foods like milk, cheese, and egg yolks. So if you have a balanced diet, you would most likely not have Vitamin A deficiency. If you did, then you would definitely notice a problem with your night vision.
