What you eat affects your eyesight just as it impacts essentially every other function of your body.  You often hear about how the nutrition you consume through your meals and snacks impacts your weight, cardiovascular health, cancer risk, and even the quality of your skin, hair and nails. What many of us don’t realize is that it can also impact our vision.

According to the American Optometric Association (AOA), making sure you have a diet rich in vitamins, minerals and antioxidants will improve your overall eye health and vision wellness. 

While eating a variety of nutritious foods is the key to making sure your eyes are nourished on a regular basis, it can be helpful to choose a vision supplement containing lutein, zeaxanthin, zinc, and vitamins C, and E. These nutrients help to support your eye wellness, particularly in the face of vision diseases such as age-related macular degeneration and cataracts, says the AOA.

Foods that contain many of these nutrients can include dark green leafy veggies, nuts, fruits, and brightly colored fruits and vegetables such as tomatoes, bell peppers and others. What you eat affects your eyesight, but taking care of your eyes can taste great! Regularly taking supplements help you to know you’re always topping up those specific nutrients your vision health loves.

It’s all well and good to know that what you eat affects your eyesight, but what’s truly fascinating is how. It’s important to understand that research is ongoing and is always improving, but we already know quite a bit about how certain nutrients can support your ocular health.

Consider what the AOA has to say about these nutrients:

  • Lutein and Zeaxanthin – This powerhouse pair has been shown to reduce the risk of certain chronic eye diseases. Many studies indicate that people who regularly consume healthy amounts of lutein and zeaxanthin are at lower risk of developing new cataracts. Aside from supplements, you can find these nutrients in dark green leafy veggies as well as brightly colored vegetables such as broccoli, corn and peas, and colorful fruits such as cooked tomatoes and fresh tangerines and persimmons.
  • Vitamin C – This vitamin is an antioxidant. Research shows that when it is consumed in combination with other essential nutrients, it can slow visual acuity loss and age-related macular degeneration. Foods containing lots of vitamin C include dark green leafy veggies, green peppers, papaya, grapefruit, oranges, and tomatoes.
  • Vitamin E – Vitamin E is another antioxidant. This one is a great one for how what you eat affects your eyesight because it can provide important protection to your eyes. This protection is against free radicals, which can break down healthy tissue. Find it in nuts, sweet potatoes and wheat germ, among other food sources.
