4.  Blind Spot  Depth Perception  Iris  Dominant Eye  Near Vision Test

5. Which one is the real mona lisa?

7.  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.

8.  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

9.  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.

10.  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.

11.  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.

12.  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

13.  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.
