Which part of the eye is responsible for adjusting the amount of light that enters?

• Lens

• Cornea

• Retina

• Iris

What is the role of the lens in the eye?

How is light energy converted in the eye?

• Into mechanical energy

• Into thermal energy

• Into chemical energy

• Into sound waves

Through which structure does the impulse leave the eye to reach the brain?
