The tear film is a thin fluid film, which covers the exposed ocular surface and is essential for the health and normal function of the eye and visual system. The various components of the tear system are highly interdependent such that any abnormality in quantity or quality of the constituents can cause an imbalance in the system, leading to signs and symptoms of dry eye disease and ultimately affecting vision.
