The eye is a natural optical tool.
pupil
cornea
retina
The light passes through the iris and the pupil.
2
Light from an object is refracted by the cornea.
1
The lens refracts the light more.
3 optic nerve
irisAn image is focused on the retina.
4
• The eyes of humans and many animals use lenses to focus images on the retina.
• The retina detects images and sends informationabout them to the brain.
