Dry eye disease is a prevalent condition characterized by insufficient lubrication of the eyes due to tears that are either inadequate or unstable. This instability can be attributed to various factors, such as insufficient tear production or the production of low-quality tears. This tear instability can result in inflammation and damage to the eye's surface.

Dry eyes can be quite uncomfortable, often causing sensations of stinging or burning. Managing this condition typically involves lifestyle adjustments and the use of eye drops. These measures are usually necessary for an extended duration to effectively control dry eye symptoms.
