The screen behind the eye lens is called the _____?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Retina
The eye works like a camera: the eye lens forms an image on a light-sensitive screen at the back of the eye, the retina. Its rods and cones turn the light into nerve signals, which the optic nerve carries to the brain.
Why the other options are incorrect
Option (1) Pupil — Incorrect. The pupil is the opening in front of the lens through which light enters the eye.
Option (2) Iris — Incorrect. The iris is the coloured ring that controls the size of the pupil.
Option (3) Ciliary muscle — Incorrect. The ciliary muscles change the curvature of the lens so that near and far objects can be focused.
