The light enters through you ____, and goes through your eye lens.
A
iris
B
pupil
C
lens
D
retina
Explanation: 

Detailed explanation-1: -First, light passes through the cornea (the clear front layer of the eye). The cornea is shaped like a dome and bends light to help the eye focus. Some of this light enters the eye through an opening called the pupil (PYOO-pul). The iris (the colored part of the eye) controls how much light the pupil lets in.

Detailed explanation-2: -Light passes through the front of the eye (cornea) to the lens. The cornea and the lens help to focus the light rays onto the back of the eye (retina). The cells in the retina absorb and convert the light to electrochemical impulses which are transferred along the optic nerve and then to the brain.

Detailed explanation-3: -Light enters the eye through the cornea. This is the clear, dome-shaped surface that covers the front of the eye. From the cornea, the light passes through the pupil. The iris, or the colored part of your eye, controls the amount of light passing through.

Detailed explanation-4: -Light enters our eyes through a thin membrane known as the cornea.
