A smooth oil layer helps prevent evaporation of the water layer, while the mucin layer spreads the tears evenly over the surface of the eye. Each component protects and nourishes the front surface of the eye. Tears are made up of three layers: oil, water, and mucus. When the normal amount of tear production decreases or tears evaporate too quickly from the eyes, symptoms of dry eye can develop. Environmental conditions, such as wind and dry climates, can also decrease tear volume due to increased tear evaporation. Tear production tends to diminish with age, with various medical conditions or as a side effect of certain medicines. Tears are produced by several glands in and around the eyelids.
