Eating healthy supports all your body’s systems. Your eyes are no exception — they need vitamins and minerals to ease your chance of having problems and protect your vision.
If you’re looking to boost your eye health and help your dry eye symptoms, focus on these key nutrients.
Omega-3 Fatty Acids
Filling up on these can ease the scratchy, stinging irritation of dry eye. Specifically, omega-3s help soothe inflammation in your eyelids or on the surface of your eye. They may also help your tears do their job better.
An omega-3-rich diet helps glands in your eye called meibomian glands make the oily part of your tears. The oil helps keep your tears from drying up too quickly in your eye.
Fish is an excellent source of omega-3 fatty acids. Go for one of these oily varieties at least twice a week:
Tuna (fresh, not canned)
You can also get omega-3 fatty acids from:
Nuts and seeds (like flaxseed)
Green, leafy vegetables
You may also need to take an omega-3 fatty acid supplement. Talk to your doctor about it before you try one.

Women should aim for a minimum of 75 milligrams a day, which is about a cup of orange juice. Men need a little more — around 90 milligrams a day.
The antioxidant power of this nutrient protects the cells in your eyes from damage. It also boosts your body’s immune system. You can get it by eating:
Wheat cereal (wheat germ)
