Omega-3 fatty acids may bring tears to the eyes of millions – in a good way. A Spanish study suggests omega-3 fatty acid supplementation may help ease the symptoms of dry eye syndrome.
More than three million American women and 1.7 million men aged 50 and older have symptoms of dry eye, reports the PUFA Newsletter. The American Optometric Association reports that the majority of people over the age of 65 experience some symptom of dry eyes.
Spanish researchers gave 61 patients who had been clinically diagnosed with meibomian gland dysfunction (dry eye) DHA-rich n-3 LC-PUFAs with antioxidants of a placebo oil for three months. They were evaluated after each month. The total daily dose of n-3 LC-PUFAs was 1.3 g, providing 1.05 g of DHA, 128 mg of EPA and 30 mg of DPA.
Subjects who had taken the daily PUFAS showed “significant improvement” in their symptoms, including improved tear stability and reduced eyelid inflammation.
The study was published in Clinical Interventions in Aging.
A different study published last year in Cornea also linked omega-3s to reduced symptoms of dry eye.
