Does Omega-3 Help With Dry Eye?

If your eyes feel scratchy, burning, or just plain uncomfortable, you might be experiencing dry eye. This condition can disrupt your day and make simple tasks like reading or using a computer feel like a chore.

If you’re living with dry eye, you might be wondering if supplements make a difference. Omega-3 fatty acids can play a supportive role in managing dry eye symptoms by helping improve the quality of your tears. Your optometrist can offer advice about how much Omega-3s to take and what other supplements might support your health.

What Are the Signs of Dry Eye?

Dry eye is a common medical condition that happens when your tears can’t provide enough lubrication for your eyes. This tear instability can lead to discomfort and a range of different symptoms. You might notice a few of these signs:

  • A stinging or burning feeling
  • Scratchiness
  • Sensitivity to light
  • Red eyes
  • Blurred vision
  • Watery eyes (the body’s response to the irritation)

The Role of Omega-3 Fatty Acids in Eye Health

Types of Omega-3

There are three main types of omega-3s—EPA, DHA, and ALA. EPA and DHA are found in fatty fish and are thought to have the most direct health benefits for your body. ALA is found in plant sources like flaxseed and nuts, but your body has to convert it to the more useful EPA and DHA forms. Current studies show that EPA and DHA are more beneficial for improving the function and quality of the meibomian glands, while there isn’t sufficient data on the efficacy of ALA.

How Omega-3 May Affect Dry Eye

Omega-3 fatty acids can help improve the function of your meibomian glands. These glands are located in your eyelids and produce the essential oil layer of your tear film. This oil prevents your tears from evaporating too quickly, and better oil quality can lead to fewer dry eye symptoms.

Get Omega-3 from Your Diet vs. Supplements

Food Sources of Omega-3

You can increase your omega-3 intake by adding certain foods to your diet. Good sources include:

  • Fatty fish like salmon, tuna, & sardines (EPA/DHA)
  • Flaxseed & chia seeds (ALA)
  • Shellfish (EPA/DHA)
  • Leafy green vegetables (ALA) 

While a healthy diet is a great start, it can be difficult to get a therapeutic amount of omega-3s from food alone.

Why Consider an Omega-3 Supplement

Supplements offer a direct and concentrated way to get specific amounts of EPA and DHA. This makes it easier to achieve the dose that may help with dry eye relief, although research on their effectiveness continues to evolve. It also removes the concern of consuming too much fish, which often contains mercury.

How to Choose a Good Omega-3 Supplement

Look for the Re-esterified Triglyceride (rTG) Form

Omega-3 supplements come in different forms, and not all are created equal. The triglyceride (TG) form is the natural structure found in fish. rTG is a form of fish oil that has been purified and processed to be more easily absorbed by the body compared to other forms like the synthetic ethyl ester (EE) form.

Check EPA & DHA Amounts

Always read the label to see how much EPA and DHA are in each capsule or serving. For dry eye, a supplement with a higher ratio of EPA to DHA is often suggested. The right dose depends on your needs, so it’s a good idea to discuss it with your optometrist.

Read the Label for Quality & Freshness

A quality supplement should be purified to remove toxins like heavy metals. It’s also important to check the expiration date. Fish oil can go bad, and rancid oil is less effective and may even be harmful to your health.

Other Supplements & Professional Dry Eye Treatments

Can Supplements Replace Eye Drops?

Omega-3 supplements are not a replacement for other dry eye treatments like artificial tears. Instead, they can be part of a broader, personalized plan to manage your symptoms effectively. Think of them as one helpful tool in your toolbox for eye comfort.

Other Options for Dry Eye Relief

Besides omega-3, other supplements like lutein and zeaxanthin can support your overall ocular health. Your treatment plan may also include preservative-free eye drops, eyelid warming masks, or in-office therapies.
