Lacrimal glands are responsible for which of the following?

• A. Production of tears
• B. Production of zonules
• C. Regulation of intraocular pressure
• D. Refraction of light

Answer: (A)

Lacrimal glands are specialized structures located in the upper outer region of each orbit of the eye, and their primary function is indeed the production of tears. Tears play a vital role in keeping the surface of the eye moist, which is essential for both comfort and maintaining clear vision. They also serve protective functions, such as flushing out dust and debris and containing antimicrobial substances that help prevent infections. The tears produced by the lacrimal glands consist of a mix of water, electrolytes, proteins, lipids, and mucins, creating a stable tear film that covers the surface of the cornea. This tear film is crucial not only for lubrication but also for providing necessary nutrients to the avascular cornea and enabling correct light refraction essential for clear vision. Understanding the specific role of the lacrimal glands helps highlight their importance in eye health and overall visual function, solidifying the choice of their role in tear production as accurate.
