Hey mate
Functions of every parts of eye are here as it is•••••
Cornea•••••
The cornea is the outer covering of the eye. This dome-shaped layer protects your eye from elements that could cause damage to the inner parts of the eye.
Iris••••••
The iris is the area of the eye that contains the pigment which gives the eye its colour. This area surrounds the pupil, and uses the dilator pupillae muscles to widen or close the pupil. This allows the eye to take in more or less light depending on how bright it is around you.
Lens••••••
The lens sits directly behind the pupil. This is a clear layer that focuses the light the pupil takes in. It is held in place by the ciliary muscles.
Pupil•••••
The pupil appears as a black dot in the middle of the eye. This black area is actually a hole that takes in light so the eye can focus on the objects in front of it.
Ciliary Muscles•••••••
Ciliary muscles allow the lens to change shape depending on the amount of light that hits it so it can be properly focused.
Retina•••••••
The light focused by the lens will be transmitted onto the retina. This is made of rods and cones arranged in layers, which will transmit light into chemicals and electrical pulses.
Optic Nerves
Optic nerves transmit the images the eye sees to the brain so that they can be interpreted.
