Consuming pumpkin seeds may help support proper vision. According to Utah State University, pumpkin seeds contain vitamin A, a nutrient that helps support your eyes. Your retinas--the tissue that lines the back of your eyeballs--use vitamin A to help sense the presence of light. The vitamin also helps to transmit visual information to your nerve cells, allowing your brain process the images you see, according to the Linus Pauling Institute at Oregon State University. Pair your pumpkin seeds with mashed pumpkin flesh for a dish containing high levels of vitamin A.
