The eye

1: Cornea

Clear covering that protects the eye and focuses light rays onto the retina

An opening in the iris that helps to control the amount of light entering the eye

A transparent, flexible, convex structure located directly behind the pupil focusing light onto the retina

The coloured part of the eye consisting of a ring of muscles that expand or contract to change the size of the pupil and control the amount of light entering the eye

2: Pupil

An opening in the iris that helps to control the amount of light entering the eye

The coloured part of the eye consisting of a ring of muscles that expand or contract to change the size of the pupil and control the amount of light entering the eye

A transparent, flexible, convex structure located directly behind the pupil focusing light onto the retina

Moves the iris adjusting the light allowed into the eye

3: Lens

A transparent, flexible, convex structure located directly behind the pupil focusing light onto the retina

Clear covering that protects the eye and focuses light rays onto the retina

Clear fluid filling the space in front of the eyeball between the lens and the cornea

An opening in the iris that helps to control the amount of light entering the eye

4: Aqueous humour

Clear fluid filling the space in front of the eyeball between the lens and the cornea

Transparent jelly like tissue filling the eyeball behind the lens

Moves the iris adjusting the light allowed into the eye

Clear covering that protects the eye and focuses light rays onto the retina

5: Iris

The coloured part of the eye consisting of a ring of muscles that expand or contract to change the size of the pupil and control the amount of light entering the eye

Clear covering that protects the eye and focuses light rays onto the retina

Layer of neural tissue at the black of the eye that receives and absorbs light, and processes images for transmission to the brain

A transparent, flexible, convex structure located directly behind the pupil focusing light onto the retina

6: Ciliary muscles

Moves the iris adjusting the light allowed into the eye

Layer of neural tissue at the black of the eye that receives and absorbs light, and processes images for transmission to the brain

A transparent, flexible, convex structure located directly behind the pupil focusing light onto the retina

An opening in the iris that helps to control the amount of light entering the eye

7: Vitreous humour

Transparent jelly like tissue filling the eyeball behind the lens

Clear fluid filling the space in front of the eyeball between the lens and the cornea

Moves the iris adjusting the light allowed into the eye

Clear covering that protects the eye and focuses light rays onto the retina

8: Retina

Layer of neural tissue at the black of the eye that receives and absorbs light, and processes images for transmission to the brain

Transmits visual information from the retina to the primary visual cortex

Clear covering that protects the eye and focuses light rays onto the retina

A transparent, flexible, convex structure located directly behind the pupil focusing light onto the retina

9: Blind spot

A small area on the retina at the back of the eye where there no photoreceptors so light cannot be detected

Transmits visual information from the retina to the primary visual cortex

Layer of neural tissue at the black of the eye that receives and absorbs light, and processes images for transmission to the brain

An opening in the iris that helps to control the amount of light entering the eye

10: Optic nerve

Transmits visual information from the retina to the primary visual cortex

Layer of neural tissue at the black of the eye that receives and absorbs light, and processes images for transmission to the brain

A transparent, flexible, convex structure located directly behind the pupil focusing light onto the retina

Clear covering that protects the eye and focuses light rays onto the retina
