Fish oil contains important dietary fatty acids that have multiple health benefits, including prevention or control of dry eyes.
Other benefits include a lower risk of heart disease and a reduction of chronic inflammation that can lead to a variety of serious diseases, including cancer and stroke. Chronic inflammation also has been indicated as an underlying cause of osteoarthritis and Alzheimer's disease.
Daily supplements of fish oil, when used alone or in tandem with lubricating eye drops, appear to reduce dry eye symptoms, including burning, stinging, redness and intermittent visual disturbances. For this reason, many eye doctors now are recommending fish oil supplements for their patients who suffer from dry eyes.
