👉 The lance fluid, also known as lacrimal mucin or mucin produced by the conjunctiva and goblet cells in the lacrimal glands, is a viscous, gel-like substance that plays a crucial role in tear film stability and ocular surface health. It is primarily composed of mucins, glycoproteins that facilitate the spreading and adhesion of tears on ocular surfaces, ensuring smooth vision by reducing friction and providing lubrication. Lance fluid also helps in the removal of debris and foreign particles from the eye, contributing to overall tear film integrity and protecting the cornea from irritation and infection.
