The Eye Parts

Front 1

Fovea

Back 1

Clear sharp colour vision. Where most cones are found.

Front 2

Sclera

Back 2

White outer layer that is tough so provides protection and structure

Front 3

Optic disc (blind spot)

Back 3

Optic nerve connects to the eye. No retina so cannot be converted into electrical impulses = blind.

Front 4

Optic nerve

Back 4

Carries electrical impulses made from the retina to the brain

Front 5

Choroid

Back 5

The pigmented vascular layer of the eyeball between the retina and the sclera. To nourish the retina and absorb scattered light.

Front 6

Lens

Back 6

Transparent biconvex lens that focuses light onto retina

Front 7

Dispensary ligaments

Back 7

Connects lens to ciliary body

Front 8

Iris

Back 8

The coloured part of the eye that controls how much light is let into the eye (changes size of pupil)

Front 9

Pupil

Back 9

Hole that allows light to enter the back of the eye

Front 10

Cornea

Back 10

Transparent outer area that protects the eye

Front 11

Aqueous humour

Back 11

Watery fluid that fills the space between the cornea and lens. Nourishes lens, cornea and helps maintain shape.

Front 12

Ciliary body

Back 12

Contains muscles that control shape and thickness of lens

Front 13

Retina

Back 13

Contains photo receptors that detect light and convert into an electrical signal/impulse.
