Dry eye disease occurs when the tear film – a three-layered coating of oil, water, and mucin – cannot adequately protect the ocular surface. Diet and nutrition can influence tear production, inflammation, and overall eye comfort. Extensive studies have linked dietary habits to an increased risk of dry eye. For example, a higher intake of fiber, protein, omega-3 fats, water, and vitamins A, C, and E was strongly associated with a lower prevalence of dry eyes. In contrast, diets high in sugar, fat, salt, and cholesterol were associated with a higher risk of dry eye. In other words, a nutrient-rich, anti-inflammatory diet may help maintain a healthy tear film and reduce symptoms of dry eye.

Key Nutrients and Foods for Tear Health

• Omega-3 Fatty Acids. These anti-inflammatory fats (EPA/DHA) from oily fish and plant sources strengthen the tear film’s lipid (oil) layer and reduce eyelid gland inflammation. Omega-3s help stabilize tears and prevent evaporation. Clinical trials show that omega-3 supplementation significantly improves dry eye symptoms, tear breakup time, and tear production. Aim for foods like salmon, mackerel, sardines, flaxseeds, chia, or walnuts daily (or supplements with 1,000–2,000 mg of total EPA/DHA), as tolerated.

• Antioxidant Vitamins (A, C, E). Vitamins A, C, and E protect the ocular surface from oxidative stress and support normal tear production. Vitamin A (retinol and carotenoids) is crucial for the health of mucin-producing goblet cells; deficiency can lead to rough, dry corneas. Vitamin C is found in especially high concentrations in tears, reflecting the eye’s need for antioxidant defense and supporting wound healing of the cornea. Vitamin E (tocopherols) protects cell membranes from free radical damage. Diets rich in dark leafy greens (spinach, kale), orange fruits/vegetables (carrots, sweet potatoes, pumpkin), bell peppers, berries, citrus fruits, and nuts will supply these vitamins. Supplementing with vitamins C and E has been shown to improve tear stability and reduce inflammation on the ocular surface.

• Hydration and Minerals. Adequate fluid intake is key: one extensive study found that higher water intake was associated with a significantly lower risk of dry eye. Dehydration can make tears more concentrated. In addition, minerals like calcium, potassium, and magnesium (abundant in dairy, legumes, leafy greens, and bananas) were associated with healthier eyes. Maintaining normal salt intake is also essential: too much sodium can dehydrate tissues and worsen dryness. A balanced diet with whole grains, beans, and limited sodium helps support tear production and electrolyte balance.

• Overall Diet Pattern. An anti-inflammatory diet – for example, a Mediterranean-style diet rich in fish, whole grains, fruits, vegetables, nuts, and olive oil – provides many of these nutrients together. Dietary fiber and lean protein (chicken, eggs, legumes) were also linked to lower dry eye prevalence. Conversely, diets high in refined carbs, added sugars, saturated/trans fats, and processed foods may promote inflammation and meibomian gland dysfunction. In practice, emphasize whole, colorful foods and limit sweets, fried foods, and excess red meat. Consider fermented foods (yogurt, kefir, kimchi) to support gut health, which may indirectly affect ocular surface inflammation.

Practical Meal and Food Ideas

• Breakfast: Oatmeal or whole-grain toast topped with ground flaxseeds or chia, walnuts, and fresh berries or banana. Add spinach or avocado on the side.

• Lunch: A leafy green salad with grilled salmon or tuna, chopped carrots, cherry tomatoes, red peppers, and pumpkin seeds, dressed with olive oil and lemon.

• Dinner: Baked or grilled fatty fish (salmon, mackerel, sardines) with steamed broccoli, sweet potato, and a mixed vegetable medley. Season with herbs (turmeric or ginger, which add anti-inflammatory benefits).

• Snacks: Yogurt or a smoothie with mixed berries (vitamin C) and kale/spinach (vitamin A); carrots or bell pepper strips with hummus; fruit (orange, kiwi, strawberries) and nuts (almonds, sunflower seeds).

• Hydration: Keep a water bottle handy throughout the day. Herbal teas and broths (e.g., miso soup) also contribute to fluid intake.

These suggestions emphasize omega-3s, colorful antioxidants, and hydration. Aim to regularly include fish twice a week, a variety of vegetables and fruits daily, and whole grains and legumes. Preparing foods (steaming or baking rather than frying) helps preserve nutrients.

Dietary Supplements

If a diet alone is insufficient or if dry eye is severe, supplements can help ensure you get adequate nutrients. Omega-3 supplements (fish oil or algal oil) are widely recommended for dry eye. Meta-analyses show that high-dose, long-term omega-3 supplementation significantly improves dry eye symptoms and tear quality. A typical dose might provide ~1,000 mg EPA+DHA per day (or as directed by a doctor). Vitamin A, C, and E supplements can be considered if dietary intake is low, for example, 500–1000 mg of vitamin C or 10–15 mg of vitamin E daily. Use with caution and avoid excessive vitamin A intake, which can be toxic. Some eye-specific supplements (containing lutein/zeaxanthin, zinc, bilberry extract, etc.) may offer added antioxidant support, though evidence is still emerging. Importantly, always discuss supplements with an eye care professional, as individual needs vary and interactions or side effects can occur.

How EYELIVIO Complements Diet for Dry Eye

Nutritional therapy addresses internal factors, but dry eye often has external components as well (e.g., poor meibomian gland function). Warming the eyelids can help unclog glands and improve the quality of tear oil. Evidence shows that daily warm compresses (about 10 minutes of moist heat) significantly improve tear film stability and meibomian gland health, relieving symptoms of dryness. The EYELIVIO® self-heating eye mask provides this therapeutic warm compression conveniently. Following the mask with an overnight lubricating ointment, such as the EYELIVIO NIGHTTIME formula, helps trap moisture and protect the ocular surface while sleeping. In combination with a nutrient-rich diet, this dual approach targets both internal (dietary) and external (eyelid) causes of dry eye, offering comprehensive relief.

For example, studies in Nutrients and other journals report that omega-3s, vitamins A, C, and E, and hydration are linked to a healthier tear film. A 2024 meta-analysis concluded that omega-3 supplementation “effectively reduces DED symptoms”. And ophthalmology reviews emphasize that warm-compress therapy (like a self-heating mask) improves meibomian gland function and tear quality.
