surface of the eye and regulating the glands that produce tears
are essential to effectively managing dry eye. Artificial tears
and rewetting drops may offer temporary relief, but this only

film has three layers: a water layer, an oil layer and a mucous
layer. The mucous layer is located on the eye surface and
