Zinc And Selenium For Eye Health

When it comes to maintaining good eye health, two essential minerals that often go overlooked are zinc and selenium. These minerals play a crucial role in supporting the overall health and function of our eyes.

The Importance of Zinc

Zinc is an essential mineral that is involved in numerous bodily functions, including eye health. It is found in high concentrations in the retina and plays a vital role in the production of melanin, a pigment that protects the eyes from harmful ultraviolet (UV) rays.

Additionally, zinc helps in the production of visual pigments in the retina, which are necessary for good vision. It also supports the health of the blood vessels in the eyes and helps prevent age-related macular degeneration (AMD), a leading cause of vision loss.

The Role of Selenium

Selenium is another important mineral that contributes to eye health. It acts as an antioxidant and helps protect the eyes from oxidative stress caused by free radicals. Free radicals can damage the cells in the eyes and contribute to the development of various eye conditions, including cataracts and age-related macular degeneration.

Selenium also plays a role in the production of glutathione peroxidase, an enzyme that helps reduce oxidative stress and inflammation in the eyes. By reducing inflammation, selenium can help alleviate symptoms of dry eye syndrome and other inflammatory eye conditions.

Food Sources of Zinc and Selenium

Including foods rich in zinc and selenium in your diet can help support your eye health. Some excellent sources of zinc include:

  • Oysters
  • Beef
  • Poultry
  • Beans
  • Nuts and seeds

On the other hand, selenium-rich foods include:

  • Brazil nuts
  • Tuna
  • Eggs
  • Whole grains
  • Spinach

Supplementing with Zinc and Selenium

In addition to obtaining these minerals through your diet, you may also consider supplementing with zinc and selenium to ensure you are meeting your daily requirements. However, it is essential to consult with a healthcare professional before starting any new supplements.

When choosing a supplement, look for those that provide the recommended daily intake of zinc and selenium. It's important not to exceed the recommended dosage, as excessive intake of these minerals can have adverse effects on your health.


Zinc and selenium are two minerals that play a crucial role in maintaining good eye health. Including zinc and selenium-rich foods in your diet or supplementing with these minerals can help support the overall health and function of your eyes. Remember to consult with a healthcare professional before making any significant changes to your diet or starting new supplements.
