When educating a group of students about the different parts of the eyeball, the nurse identifies which as the function of the lens?
A) Permits light rays to enter the front of the eye
B) Brings oxygen and nutrients to the eye
C) Gives the eye its specific color
D) Focuses the light rays on the retina
D
Feedback:
The function of the lens is to focus light rays on the retina. The function of the cornea is to permit light rays to enter the eye. The choroid layer brings oxygen and nutrients to the eye, whereas the iris gives the eye its specific color. Supplying the eye with oxygen and nutrients, giving the eye its specific color, and focusing the light rays on the retina are not the functions of the cornea.
