Essential Nutrients For Eye Health

Certain essential nutrients promote eye health (Lawrenson and Downie, 2019). 

• Vitamin A is essential for maintaining retinal health and producing rhodopsin, a protein that aids vision in low light.
  
  

• Lutein and zeaxanthin, powerful antioxidants, protect our eyes from harmful UV and blue light, reducing the risk of age-related macular degeneration and cataracts.
  
  

• Vitamin C combats oxidative stress, protecting the eye's lens and retina, while vitamin E prevents cellular damage by neutralising free radicals.
  
  

• Omega-3 fatty acids maintain the structural integrity of cell membranes in the retina and reduce inflammation, preventing dry eyes and supporting overall eye health.

The following table highlights the recommended daily intake of these essential nutrients for eye health:

Essential Foods for Eye Health

Including these foods for healthy eyes in your diet can help strengthen your eyes and reduce the risk of eye-related problems as you age.

1. Leafy Greens

Spinach, kale and collard greens have antioxidants lutein and zeaxanthin that protect the eyes. These vitamins work by blocking damaging blue light, they also function as a natural sunblock for your eyes. Eating foods with these nutrients lessens the chance of cataracts and AMD (age-related macular degeneration). Lightly steam or saute to preserve their benefits for your eyes.

2. Carrots

In carrots, beta-carotene exists and is a forerunner of vitamin A. Vitamin A is necessary for good vision because the retina's protein, rhodopsin, which helps with night vision, relies on it. Eat carrots raw or gently cooked in butter to ensure you get the most absorption of their beta-carotene.

3. Citrus Fruits

Oranges, lemons, and grapefruits are abundant in vitamin C, an antioxidant that helps prevent cataracts and AMD by battling oxidative stress in the eye. Additionally, vitamin C maintains the health of the blood vessels in the eyes. To retain their vitamin C content, enjoy them fresh or as a juice (along with fibre).

4. Berries

Antioxidants like vitamin C and flavonoids, which are present in blueberries, strawberries and blackberries, protect the eyes from free radical harm and can reduce the occurrence of cataracts as well as AMD. They can be mixed into salads or added to yoghurt and smoothies.

5. Fatty Fish

Sardines, salmon, and trout are great providers of omega-3 fatty acids, especially DHA and EPA, which are crucial for maintaining the structural integrity of cell membranes in the retina. Additionally, omega-3s contain anti-inflammatory qualities that lessen the chance of AMD and help avoid dry eyes. Grill, bake, or broil to preserve omega-3 fatty acids.

6. Nuts And Seeds

Almonds, walnuts, chia seeds, and flaxseeds provide vitamin E and omega-3 fatty acids. Vitamin E is a powerful antioxidant that protects eye cells from oxidative damage, while omega-3s help reduce inflammation and maintain eye moisture. Eat raw or lightly toasted for a nutritious snack.

7. Eggs

Zinc, zeaxanthin, and lutein are abundant in egg yolks. Zeaxanthin and lutein act as shields for the eyes from harmful blue light and lower the chance of AMD, while zinc is essential for maintaining the retina's health and may help prevent night blindness. Cook them however you like, but keep them from overcooking them to preserve nutrients.

8. Bell Peppers

Bell peppers (red, yellow, and orange) are rich in beta-carotene and vitamin C. Antioxidant vitamin C helps shield the eyes from oxidative stress, and beta-carotene enhances vision by being metabolised by the body into vitamin A. Eat them raw in salads or lightly saute them to retain their vitamin C content.
