Question

The ____________ of the eye works similarly to the shutter of a camera.
A)Eyelid
B)Lens
C)Cornea
D)Iris

Accepted Answer

The iris of the eye works similarly to the shutter of a camera in regulating the amount of light that enters the eye. The iris adjusts the size of the pupil to control the amount of light that reaches the retina, just like the shutter of a camera adjusts the aperture to control the amount of light that reaches the film or sensor. Therefore, the correct choice is D) Iris.
