Your eyes require good nutrition, including certain important vitamins and minerals, to function properly. Morbidly obese individuals tend to have very poor nutrition and often suffer from diabetes, which can lead to blindness. Therefore, to keep your eyes sharp, improve your nutrition and lower your weight.
To nourish your eyes, eat foods that contain beta-carotene, a precursor to vitamin A. The vitamin forms a substance in retinas called rhodopsin, necessary for night vision. Without enough vitamin A, you won’t be able to see in dim light. Another side effect of beta-carotene deficiency is macular degeneration, which can end in blindness. Good sources of beta-carotene include:
- Dark leafy greens
- Pumpkin and squash
- Sweet potatoes
Another important nutrient is lutein, which can help prevent macular degeneration. It is found in pretty much the same foods as those that supply beta-carotene, plus corn.

You can get your vitamins through a pill, but it’s more effective to get them through your diet. Good fats come from salmon, sardines and flax.
