Can fish oil help with dry eyes

Many individuals wonder if consuming fish or fish oil can help manage their dry eye symptoms

Omega-3 fatty acids found in fish oil possess anti-inflammatory properties that can treat dry eyes.  

However, additional research is required to determine whether omega-3s can specifically assist dry eye treatment or not. 

One can have fish oil in the form of a supplement for Dry Eyes available in liquid or capsule form. 

Fish oil can also be obtained by eating oily fish like tuna, salmon, and trout.

Docosahexaenoic Acid (DHA) and Eicosapentaenoic Acid (EPA) are two omega-3 fatty acids found in fish oil. 

Omega-3s from fish oil have anti-inflammatory and antioxidant qualities that provide several health advantages. 

These omega-3 fatty acids help boost the creation of the oil that makes up a portion of your tears. 

EPA and DHA also aid in lowering inflammation throughout the body, including the region around the eyes thus treating dry skin around the eyes.

However, the benefits of DHA and other omega-3 fatty acids for treating and preventing dry eye are still being investigated by researchers.

Apart from providing healthy eyes, fish oil also supports heart health and improves skin tone.

The American Academy of Ophthalmology (AAO) states that omega-3 oils may enhance meibomian gland function that aid in overcoming dry eye symptoms.

Dry eyes can occur due to issues with the oily layer of tears.

According to the AAO, the omega-3s in fish oil can reduce inflammation of the eyelids or front surface, thus helping relieve the symptoms of dry eye.

In a 2016 study, it was found that EPA and DHA supplementation shows a substantial reduction in dry eye symptoms.

Also, it has been found that omega-3 can aid in decreasing ocular inflammation following cataract surgery.

This further helps in treating dry eye after the cataract surgery.

According to another study, omega-3 fatty acids can help protect corneal nerves in dry eyes from further damage.
