Photo of author

Dry eye is a common eye condition that may lead to eye discomfort in severe cases.

But dry eyes can be managed effectively using treatment options such as artificial tears and eye drops.

However, several other supplements, such as vitamins and probiotics, might also help relieve some symptoms.

So can you take fish oil for dry eyes?

Let us proceed with this article to find the answer to your question and discuss the benefits and effectiveness of fish oil for dry eyes in detail.

Can You Take Fish Oil for Dry Eyes

Yes, you may take fish oil for dry eyes

Several individuals have experienced relief in their dry eye symptoms after taking fish oil supplements.

This is due to the rich content of Omega-3 fatty acids in fish oil.

Omega-3 fatty acids are known to have anti-inflammatory properties. 

As inflammation is one of the common dry eye causes, fish oil may provide relief in such cases.

Besides their anti-inflammatory properties, Omega-3 acids are also associated with the healthy functioning of Meibomian glands.

These glands are located near the corners of the eyes and produce oil, an important component of tears.

Therefore, consuming fish oil may improve oil production in tears.

This oil produced in the tears helps keep the eyes smooth and lubricated, reducing the risk of developing dry eyes.

However, it is important to know that while some studies have mentioned the effectiveness of fish oil for dry eyes, others have found contradictory results.

Therefore, you should consult your eye doctor before taking Omega-3 supplements. They may prescribe other options besides fish oil, such as eye drops or pills, to treat dry eyes.

    The effectiveness of fish oil for dry eyes may vary in individuals, depending upon various factors.

    However, studies on dry eyes and fish oil have shown mixed results.

    A study published in the British Contact Lens Association suggests that Omega-3 fatty acids can lead to decreased tear evaporation rate and relieved dry eye symptoms.

    Another study found that Omega-3 supplements are ineffective in improving dry eye conditions.

    Therefore, it is recommended to consult a certified doctor for your dry eye condition.

    If the dry eyes are caused due to any deficiency, your doctor may recommend some dry eye supplements such as vitamins to manage dry oil.

    Other Effective Treatment of Dry Eyes

    Although some studies have mentioned the effectiveness of fish oil for dry eyes, it lacks sufficient data on its effectiveness.

    Therefore, it is advised to seek proper treatment for dry eyes from an eye specialist.

    For mild cases, artificial tears and lifestyle changes might be helpful to relieve the symptoms of dry eyes.

    If the condition worsens, your doctor may prescribe eye drops and oral pills to manage dry eyes effectively. 

    However, if these dry eye medicines and eye drops are ineffective in treating dry eyes, they may also recommend undergoing surgery.

    Besides these treatment methods, home remedies can also help with dry eyes. To learn more about dry eyes, read Home Remedies for Dry Eyes: Natural Relief and Effective Solutions.

    Apart from aiding dry eyes, fish oil is also found to improve cardiovascular functions in the body.


    Although the role of fish oil for dry eyes is debatable, it is crucial for overall eye health.

    The Omega-3 fatty acids present in fish oil are responsible for the proper functioning of several body functions and improve oil production in the eyes.

    Also, Omega-3 fatty acids have anti-inflammatory properties, which may ease certain dry eye symptoms.

    Due to this reason, fish oil may improve dry eye condition for some patients.

    However, the exact effects of fish oil in treating dry eyes are still a subject of research.

    Therefore, it is advised to consult a certified eye doctor when you observe any dry eye symptoms.
