Question

what role do the eyebrows play in eye protection?
they keep sweat away from the eyes
they focus light onto the retina
they adjust the amount of light entering the eye
they detect changes in light intensity

Explanation:

Eyebrows act as a physical barrier that redirects sweat, along with small debris and rain, away from the eye surface, preventing irritation and potential damage. The other options describe functions of other eye structures: the lens focuses light onto the retina, the iris adjusts light entry, and photoreceptors detect light intensity changes.

Answer:

They keep sweat away from the eyes
