Why do we have eyelashes and eyelids?

Eyelashes and eyelids serve crucial protective functions for the eyes. Eyelashes help to trap dust, debris, and small particles, preventing them from entering the eye, while also triggering a blink reflex to shield the eye from potential threats. Eyelids provide a protective barrier and help to keep the eye moist by spreading tears across its surface during blinking. Together, they contribute to overall eye health and visual clarity.
