What is the primary function of the lacrimal system?

The primary function of the lacrimal system is tear production and drainage. This system is crucial for maintaining proper eye health and function by producing tears that keep the surface of the eye moist, which is essential for comfort and clear vision. Tears help to lubricate the eye, wash away foreign particles, and contain enzymes that can protect against infection.

Additionally, the lacrimal system drains excess tears away from the eye through the nasolacrimal duct into the nasal cavity. This drainage prevents tears from overflowing, maintaining a balance and ensuring that the eye remains hydrated without excessive moisture. Understanding this function highlights the importance of the lacrimal system in overall ocular health and comfort.
