tears

   Also found in: Dictionary/thesaurus, Medical, Legal, Acronyms, Idioms, Encyclopedia, Wikipedia 0.01 sec.

tears

Salty fluid exuded by lacrimal glands in the eyes. The fluid contains proteins that are antibacterial, and also absorbs oils and mucus. Apart from cleaning and disinfecting the surface of the eye, the fluid supplies nutrients to the cornea, which does not have a blood supply.

If insufficient fluid is produced, as sometimes happens in older people, the painful condition of ‘dry-eye’ results and the eye may be damaged.
