please answer. my question

Answer 1

hey,

The sclera, or white part of the eye, protects the eyeball. ... The cornea, a clear window at the front of the eye, covers the iris and the pupil. A clear lens, located behind the pupil, acts like a camera lens by focusing light onto the retina at the back of the eye.

The retina is a light-sensitive inner lining at the back of the eye. Ten different layers of cells work together in the retina to detect light and turn it into electrical impulses.

Special cells called cones and rods are located in the retina. These cells are known as photoreceptors and help absorb light.

Cones

Cones are located in the macula, or central area, of the retina. Cone cells help us see colour and detail. Similarly, the macula allows us to read and clearly recognize people's facial details, such as eye colour and whether they have freckles.

Rods

Rods are located in the peripheral, or outer area, of the retina. Rod cells allow us to see in poor lighting and give us our night vision.
