Lachrymals, also known as tear ducts, are small passages in the eyes that help in the production and flow of tears. These passages are responsible for the moistness of the eyes and their proper functioning is crucial for maintaining clear, healthy vision. Some synonyms for lachrymals include tear glands, lacrimal glands, and weeping glands. Other related terms include the tear film, the nasolacrimal duct, and lacrimal canals. It is important to keep the lachrymals healthy and functioning properly through practices such as blinking often, keeping hydrated, and avoiding irritants that can cause dryness or inflammation of the eyes.
