More than 360 million people around the world suffer from chronically red, scratchy or irritated eyes, a condition that can worsen with stress.

Laughter therapy for dry eye disease worked in reducing discomfort. It improved tear stability, gland function, and mental health.

Dry eye is commonly treated with lubricant eye drops, but according to a new study, laughter exercise could be just as effective.
