Dry eye syndrome affects millions of people worldwide, causing discomfort, blurred vision, and chronic irritation. While artificial tears and prescription medications are common treatments, growing research shows that nutrition—particularly Omega-3 fatty acids—can play a critical role in supporting long-term eye health.
👁️ What Is Dry Eye Syndrome?
Dry eye syndrome occurs when your eyes don’t produce enough tears, or when the quality of tears is poor. This leads to dryness, stinging, redness, light sensitivity, and even vision disturbances.
🔬 The Tear Film & Ocular Surface Society (TFOS) DEWS II Report classifies dry eye as a multifactorial disease of the ocular surface, often linked to inflammation and tear film instability.
🧪 The Role of Omega-3s in Eye Health
Omega-3 fatty acids—especially EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid)—are long-chain polyunsaturated fats that help reduce inflammation and maintain the integrity of tear-producing glands.
🔬 A 2019 meta-analysis published in Cornea found that Omega-3 supplementation significantly improved dry eye symptoms and tear stability in patients compared to placebo.

EPA reduces ocular surface inflammation, while DHA supports the structure of eye tissues. Together, they help maintain tear film production and reduce the burning, itching, and stinging often associated with dry eye syndrome.
🩸 Measure Before You Supplement
Instead of guessing, you can test your Omega-3 status to determine if low levels may be contributing to your symptoms.
📊 Our Omega-3 Index Test measures the EPA and DHA content of your red blood cells—a strong marker for long-term omega-3 status.
People with low Omega-3 Index scores (below 4%) may be at greater risk for inflammatory eye conditions like dry eye.
🥗 Dietary Sources & Supplementation
To raise your Omega-3 Index and potentially improve eye moisture:
-
Eat more fatty fish (salmon, sardines, anchovies)
-
Consider a high-quality Omega-3 supplement with at least 1,000mg of combined EPA + DHA
-
Reduce Omega-6 intake (e.g., seed oils) to help improve the Omega-6:3 balance
📉 Studies show that an optimal Omega-3 Index is 8% or higher for anti-inflammatory benefits and chronic disease risk reduction.
👨⚕️ Clinical Endorsement
The American Academy of Ophthalmology (AAO) acknowledges Omega-3s as a supportive strategy for dry eye relief—especially for people who prefer natural, non-pharmaceutical options.
And while prescription treatments may still be necessary for severe cases, addressing underlying inflammation with Omega-3s is often the missing piece.
🔄 Test, Track & Improve
Dry eye can be persistent and frustrating. But testing your Omega-3 levels is a powerful first step toward identifying whether inflammation or dietary imbalance is playing a role.

🙋 Frequently Asked Questions (FAQ)
Q: How do Omega-3s help with dry eye syndrome?
A: EPA and DHA reduce inflammation, improve tear gland function, and stabilize the tear film—leading to reduced dryness and irritation.
Q: What’s a good Omega-3 Index for eye health?
A: Aim for an Omega-3 Index of 8% or above. Below 4% is considered low and may be linked to inflammatory conditions like dry eye.
Q: Can I improve my Omega-3 Index with diet alone?
A: It depends on your baseline. Fatty fish 2–3 times per week helps, but many people require supplements to reach optimal levels.
