What is the composition of Aqueous Tears?

• A. Oily component
• B. Watery component
• C. Protein component
• D. Saline component

Answer: (B)

The composition of aqueous tears primarily consists of a watery component, which is crucial for maintaining the health and function of the eyes. This watery layer serves several significant purposes: it helps to lubricate the eye surface, wash away foreign particles, and provides a medium for the distribution of nutrients and oxygen to the cornea, which does not have its own blood supply.

Additionally, this aqueous portion of tears contains a balance of salts, proteins, and other substances that contribute to the overall function and stability of the tear film. While there are indeed oily and saline components in the tear film, the predominant characteristic and function relate to the watery aspect, making it essential for tear production and eye comfort.
