What is the main purpose of the conjunctiva?

  1. To protect the lens from damage

  2. To allow light entry into the eye

  3. To keep the surface of the eye moist and protected

  4. To facilitate the movement of the eyeball

The correct answer is: To keep the surface of the eye moist and protected

The main purpose of the conjunctiva is to keep the surface of the eye moist and protected. This thin, transparent membrane covers the inner surface of the eyelids and the white part of the eyeball, helping to maintain moisture through the secretion of mucus and tears. It also serves as a barrier to protect the eye from pathogens and foreign bodies, contributing to overall ocular health. The conjunctiva plays a crucial role in the immune defense of the eye, helping to prevent infections while ensuring that the eye remains lubricated, thus supporting clear vision and comfort.
