Does fish oil help dry eye?

A new study, the largest to-date, shows that taking fish oil providing 3000 mg of omega-3 fatty acids each day for 12 months doesn’t help dry eye. This new data conflicts with recommendations made by many physicians to try omega-3 fatty acids to improve dry eye symptoms if other dry eye treatments don't work well enough. The recommendations, which have been popular for years, are based on results from earlier studies showing that fish oil can reduce symptoms of dry eye such as pain, blurred vision, and sensitivity. Review our recently updated monograph to learn potential reasons for the conflicting results in the newest study. Also find out if these new results really mean that fish oil is unlikely to be beneficial for any patient with dry eye.
