How Is Diet an Important Factor for Maintaining Good Eyesight?

Researchers from the American Optometric Association have found that taking particular vitamins and consuming nutrient-rich foods can prevent eye issues like cataracts and macular degeneration. Vitamins A, C, and E, fatty acids, lutein, and zinc are the most useful to take care of your eyes.


Lutein is found in dark leafy vegetables, can reduce the risk of chronic eye diseases, and lowers your risk for developing cataracts. You can also get lutein from vegetables and fruit like broccoli, corn, peas, and tangerines.

Vitamin A

Vitamin A deficiency is one of the leading causes of blindness. It is essential for photoreceptors, and a lack of proper intake can cause night blindness and dry eyes, among other symptoms. Eating foods rich in beta-carotene—such as spinach, kale, other leafy greens, and dairy products like eggs—will significantly improve Vitamin A levels.

Vitamin C

Vitamin C can prevent cataracts and age-related macular degeneration (AMD) by consuming fruits like grapefruit, oranges, strawberries, green peppers, and tomatoes. Vitamin E is essential to protect your eyes from free radicals that can wear down your eye’s healthy tissue. Vegetable oils, sweet potatoes, nuts, and wheat contain Vitamin E.


Zinc plays a vital role in producing melanin, which forms a protective pigment for your eyes. Zinc deficiency has been linked to health issues such as poor night vision and cloudy cataracts. Zinc can naturally be found in red meat, shellfish, nuts, and seeds.

Fatty Acids

Seafood can be a great source of nutrients for overall eye health, as salmon and tuna are rich in fatty acids. They help your body produce tears and reduce inflammation.

Can Poor Nutrition Cause Vision Problems?

While nutrient-rich foods have known benefits for your vision, other foods can negatively impact your eye health. Many foods are considered unhealthy, but people do not realize their far-reaching impact on your eye and overall health.

  • Diet soda: According to a 2018 study, people who consumed more than four cans of diet soda per week had a significantly higher risk of developing proliferative diabetic retinopathy (a progressive retinal disease).
  • High sodium: Diets high in sodium lead to an increased risk of cataracts.
  • Refined carbohydrates: Foods with a high glycemic index, such as highly processed wheat and grains, put individuals at risk of age-related muscular degeneration (AMD). Some examples of refined carbs include white bread, muffins, cookies, and pasta.
  • Dehydration: A lack of water intake can cause dry, itchy, and irritated eyes.
