2. HOW WE SEE?
PUPIL
OPTIC
NERVE
LENS
RETINA
CORNEA
The light goes to the object and it is reflected to
the eye.
The light reflected passes through the pupil and
goes to our retina forming an inverted image.
3. The optic nerve transports the nervous impulses
generated in the retina to the brain.
The brain interprets the impulses received and
form an image which is what we perceive
HOW WE SEE?
4. But this process can be interfered by a serie of factors
that can make our brain form a wrong or false
interpretation.
-Wrong: Our brain interprets wrongly the visual
information.
-False: Our brain forms an image that it doesn´t exist.
These phenomena are called optical illusions.
