Tear Film

The tear film is a thin layer of fluid that covers the surface of your eyes, playing a crucial role in maintaining eye health and clear vision. It consists of three main components: an oily layer that prevents evaporation, a watery middle layer that supplies nutrients and flushes out debris, and a mucous layer that helps the tears stick evenly across the eye. This complex coating keeps the eye moist, provides a smooth surface for the cornea, and helps protect against infections. Proper tear function is essential for comfort and optimal eyesight.
