Which one is the real mona lisa?

The blind spot is the area on the retina
without receptors that respond to light.
Therefore an image that falls on this region
will NOT be seen. It is in this region that the
optic nerve exits the eye on its way to the
brain.
The act of concentrating attention on the cross throws its image
on to the fovea and the image of the dot on to the periphery of the
retina to the left of the fovea. As the book approaches the face,
the distance between the images of the cross and dot increases
until that of the dot falls on the blind spot, whereupon the dot
disappears (Figs. 1a and b).
 These results can be used to establish the relative positions of the
blind spot and fovea since the dot cannot be made to disappear
when the experiment is repeated with the dot and cross in other
positions.
 One is not usually aware of the blind spot because (a) both eyes
are used, (b) the eyes make constant scanning movements (c) the
gap in the visual field never coincides with the image of the object
on which we are concentrating and (d) the brain 'fills in' the gap


The circular band of muscles that controls the
size of the pupil. The pigmentation of the iris
gives "color" to the eye. Blue eyes have the
least amount of pigment; brown eyes have
the most.

Two eyes are better than one, especially
when it comes to depth perception. Depth
perception is the ability to judge objects that
are nearer or farther than others. pencils
together.

When light enters the eye, it is first bent
(refracted) by the cornea. Light is bent
further by the lens of the eye in a process
called accomodation. To bring an image into
sharp focus on the retina, the lens of the eye
changes shape by bulging out or flattening. A
flatter lens refracts less light.

Close one eye and stare at a point about 20
feet away. It should be in focus. Keep
focusing on the point and raise one of your
fingers into your line of sight just below the
point. Your finger should be a bit blurred.
Now, change focus: look at the tip of your
finger instead of the point 20 feet away. Your
finger will come in focus, but the distant point
will be blurred

There is a vast difference between the
information sent to the brain by the sense
organs and the interpretation made by the
brain. This interpretation is called perception
and depends, to a great extent, on learning
and past experience.
