Physicists working to cure 'dry eye' disease

The eye is an exquisitely sensitive system with many aspects that remain somewhat of a mystery--both in the laboratory and in the clinic. A U.S.-based team of mathematicians and optometrists is working to change this by gaining a better understanding of the inner workings of tear film distribution over the eye's surface. This, in turn, may lead to better treatments or a cure for the tear film disease known as "dry eye." They describe their work in the journal Physics of Fluids.
