👉 Contacts fluid, also known as tear fluid, is a critical component of the ocular surface system that maintains the health and function of the cornea and conjunctiva. This clear, aqueous solution is produced by the lacrimal glands and other ocular structures and serves multiple essential roles: it lubricates the eye to prevent dryness and irritation, provides nutrients to the corneal epithelium, helps maintain proper tear film stability by balancing evaporation and spreading, and has antimicrobial properties to protect against infections. The fluid also plays a role in the removal of metabolic waste and debris from the ocular surface, ensuring optimal visual acuity and overall eye health.
