Retina
Where the image is formed. The light sensitive layer of the eye. Contains light sensitive receptor cells. Carries imulses to the optic nerve so they can be sent to the brain

Pupil
The hole in the centre of the iris which allows light to enter
2 of 9
Blind Spot
Where the optic nerve leaves the eye. Contains no light sensitive receptors
3 of 9
Cornea
Clear part of the sclera which allows light through

Lens
Bends/Refracts and changes shape to focus light onto retina
