Bananas are a good source of vitamin A, which is essential for eye health. Vitamin A helps protect the cornea, the outer layer of the eye, and plays a role in night vision.
While bananas do contain vitamin A, they are not the most potent source. Foods like sweet potatoes, carrots, and spinach are much richer in vitamin A.
Therefore, while bananas can contribute to your overall eye health, they are not a primary source of the nutrients needed for good vision. It's important to eat a balanced diet with various fruits and vegetables to ensure you are getting all the nutrients your eyes need.
