why is it that we each have a blind spot?

Question

i'm doing a science experiment about how everybody has a blind spot that we don't know about. does anybody know why that is?

Answer 1

The optic disc or optic nerve head is the location where ganglion cell axons exit the eye to form the optic nerve. There are no light sensitive rods or cones to respond to a light stimulus at this point thus it is also known as "the blind spot" or "anatomical blind spot"; the break in the visual field created by the optic disc is also called "the blind spot" or "physiological blind spot". The optic nerve head in a normal human eye carries from 1 to 1.2 million neurons from the eye towards the brain.

Answer 2

Hi. Look in the mirror at one of your eyes. Then look at the other eye. Did you see your eyes move? No. We are blind while our eyes are in fast motion. (Keeps the brain from processing useless blurs.) But that isn't what you asked. Draw the X and O ( without the hyphens) below on a piece of white paper about 3 inches apart. If you move your head closer to the paper you will reach a distance where both letters will be in your blind spots. Close one eye, your right, and look at the O. Then close the other and look at the X. Weird, huh?


X................O

Answer 3

There is a place in your eye where the retina, the layer of your eye that generates neuronic signals from light, has no structures that enable it to do so, because the optic nerve uses that space to house its subdivisions. That is the blind spot.

Read answer number 1......My car has a large blind spot.......

Answer 5

its where the optic nerve joins to the eye at back where the retina is.
