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
