The part of the eye responsible for fine-tuning the refraction of incoming light is the _____.

lens
retina
optic nerve
cornea

Answer 1

The lens i guess... im not entirely sure thoug

Answer 2

The answer is the lens.


The eyeball is filled with a water-like fluid. In front of the eyeball, there is the

cornea. It is a transparent structure that refracts light. A portion of light passes

through the pupil which allows light to enter the eye. The amount of light that will

pass through the pupil depends on dilatation of iris. Once the light enters the

eye, it enters the lens. Lens of the eye is able to change its size and that way is

responsible for fine-tuning the refraction of the light. The light later reaches the

retina.
