The membrane that covers the outer surface of the eye and lines the eyelids is
the
choroid
sclera
conjunctiva
retina

The conjunctiva plays a crucial role in keeping the eye moist and providing a barrier against pathogens. This thin membrane is not only protective but also contributes to eye comfort, especially when we blink, as it helps spread tears evenly over the surface.

In real-world scenarios, understanding conjunctiva’s function is vital for eye care. Issues like conjunctivitis (commonly known as pink eye) can arise due to infection or allergies. Regular handwashing and avoiding touching the eyes can help maintain conjunctival health, illustrating just how interconnected our daily habits are with eye wellness!
