Incoming light rays refer to the beams of light that enter the eye through the cornea and pass through the pupil, ultimately reaching the retina.
Cornea: The transparent outer layer of the eye that helps refract incoming light rays towards the pupil.
The adjustable opening in the center of the iris that controls how much light enters the eye.
The innermost layer of tissue at the back of the eye where incoming light rays are converted into electrical signals for processing by the brain.
