Question

question 18
what is the primary function of the cornea?
a protects the eye
b produces tears
c transmits visual information
d bends light to focus on the retina

Explanation:

The cornea is the clear outer layer of the eye. Its primary role is to refract (bend) incoming light to focus it onto the retina, enabling vision. While it offers some protection, this is secondary to light focusing. Tear production is by lacrimal glands, and visual information transmission is by the optic nerve.

Answer:

D. Bends light to focus on the retina
