👉 Tear fluid, also known as lacrimal fluid, is a clear, watery substance produced by the lacrimal glands in the eyelids. It plays a crucial role in maintaining eye health and comfort by lubricating the eye surface, removing debris and foreign particles, and providing antimicrobial protection. Composed mainly of water (99%), proteins, electrolytes, and various nutrients, tear fluid also contains enzymes that help break down bacteria and viruses. This fluid ensures that the eye remains moist, clear, and free from irritation, facilitating optimal vision and overall ocular health.
