The lacrimal glands are small, almond-shaped glands located above each eye. Their primary function is to produce tears, which help keep the surface of the eye moist and comfortable. Tears also play a crucial role in protecting the eyes from irritants and infections. When the lacrimal glands produce tears, they release them onto the surface of the eye through tiny ducts. These tears then drain into the nasolacrimal duct, which leads to the nose. This process helps maintain eye health and provides a clear vision by washing away debris and providing lubrication.
