Vitamin A ensures that your light-sensing retina functions properly and also protects your retina and overall vision, according to Providence Eye & Laser Specialists. If you don’t get enough vitamin A, you could be at risk for eye infections, dry eyes, or eye inflammation. A 6-ounce container of plain, low-fat yogurt has 88 IU of vitamin A.
Your eyes have a high concentration of zinc in them, particularly in the retina-choroid complex, according to a 2019 article in Molecular Nutrition and Food Research. When you age, levels of zinc in your eyes decrease, which might lead to eye diseases such as age-related macular degeneration (AMD). Supplementing your diet with zinc could prevent the progression of AMD. Zinc might also reduce inflammation in the retina, and yogurt has 1.5 milligrams of vitamin A.
A 2019 study in the European Journal of Nutrition investigated the link between dairy consumption and the risk of cataracts in people who had a high risk of cardiovascular disease. People who ate more nonfat yogurt had a significantly lower risk of developing cataracts.
