Dry Eyes

Dry eyes are a very common condition that can cause discomfort, irritation, and blurred vision. Symptoms may include stinging, burning, redness, and a gritty sensation as if something is in the eye. Many people experience dry eyes due to environmental factors, aging, hormonal changes, screen use, contact lenses, or certain medical conditions.

While artificial tears and eye drops provide temporary relief, long-term support often comes from the inside out. Nutrition and hydration are essential in maintaining a healthy tear film and reducing the risk of dry eye syndrome.

How Nutrition Supports Dry Eyes

The eye’s tear film has three layers—oil, water, and mucus—all of which need the right balance of nutrients to function properly. When the tear film is unstable, the eyes dry out quickly. A diet rich in omega-3 fatty acids, vitamins, antioxidants, and minerals helps strengthen and stabilise the tear film, protecting against dryness and inflammation.

Key Nutrients for Dry Eye Relief

Omega-3 Fatty Acids – Tear Film Support

Omega-3s reduce inflammation of the oil glands in the eyelids, improving tear quality and reducing evaporative dry eye.

  • Food sources: Salmon, sardines, mackerel, flaxseeds, chia seeds, hemp seeds, walnuts.

Vitamin A – Corneal Protection

Vitamin A supports the health of the cornea and helps maintain proper tear production. Deficiency is strongly linked to severe dry eye.

  • Food sources: Carrots, sweet potato, pumpkin, kale, spinach, and egg yolks.

Vitamin C – Collagen & Tissue Repair

Vitamin C aids in collagen production, keeping the cornea and ocular surface strong and resilient.

  • Food sources: Citrus fruits, strawberries, kiwi, capsicum, and broccoli.

Vitamin E – Antioxidant Protection

Vitamin E helps protect delicate eye tissues from oxidative stress, which can worsen dry eye symptoms.

  • Food sources: Almonds, sunflower seeds, hazelnuts, spinach, and avocado.

Zinc – Tear Gland Function

Zinc supports vitamin A metabolism and helps maintain healthy cells in the eyes, including the tear glands.

  • Food sources: Oysters, beef, chicken, pumpkin seeds, lentils, and whole grains.

Hydration and Dry Eyes

Dehydration is a key contributor to dry eye syndrome. Adequate fluid intake ensures your body produces enough tears to keep your eyes moist and comfortable.

  • Aim for: 6–8 glasses of water daily, more if in hot climates or during exercise.
  • Hydrating foods: Watermelon, cucumber, celery, and citrus fruits.
  • Helpful beverages: Herbal teas, coconut water.
  • Limit: Excess caffeine and alcohol, as they can dehydrate the body.

Lifestyle Tips for Managing Dry Eyes

Alongside nutrition and hydration, simple lifestyle changes can help relieve dry eyes:

  • Take regular screen breaks: Follow the 20-20-20 rule (look 20 feet away for 20 seconds every 20 minutes).
  • Use a humidifier: Adds moisture to dry indoor air, especially in winter or with heating/air conditioning.
  • Protect your eyes outdoors: Wear sunglasses that block 100% UV rays to reduce irritation from wind and sunlight.
  • Blink more often: Especially when reading or using digital devices.
  • Consider warm compresses: They help unblock oil glands in the eyelids, improving tear quality.

Dry eyes can be frustrating, but with the right approach, symptoms can often be managed naturally. A diet rich in omega-3 fatty acids, vitamin A, vitamin C, vitamin E, and zinc, combined with proper hydration, provides a strong foundation for eye comfort. When paired with healthy daily habits such as screen breaks, humidifier use, and UV protection, nutrition can play a vital role in reducing dry eye symptoms and supporting overall eye health.
