Question

9. The part of eye that helps to focus light
onto the retina.​

Answer 1

Answer:

Basically, the role of the eye is to convert light into electrical signals called nerve impulses that the brain converts into images of our surroundings. Light rays pass through the pupil in the cornea.

Aqueous humour – maintains the pressure in your eye and nourishes the cornea and the lens by supplying amino acids and glucose, as well as vitamin C.

Choroid – a thin layer of blood vessels that nourish the retina and absorb scattered light.

Ciliary muscles – a circular muscle that relaxes or tightens to enable the lens to change shape for focusing.
