The "blind spot" in all mammals is the tiny area on the retina (light-sensing surface inside the eye) where the optic nerve exits the eye, carrying the optical signals to the brain. It is "blind" because there are no photoreceptors on this tiny area of the retina. In humans, the blind spot in the right eye is about 20 degrees directly to the right of that eye's central vision. In the left eye it is about 20 degrees to the left of that eye's central vision. Thus, normally the opposite eye sees what is in the other eye's blind spot and the brain fills in the missing information. Here is a simple way to demonstrate the blind spot. (I apologize for the ... between the X and W, but formatting is limited here.) To demo the blind spot in your right eye, keep your left eye closed and look directly at the "X" with your right eye. Now move closer or farther from the screen. At about a foot from the screen the W will "disappear" in your peripheral vision (if you look toward the W, it will reappear). To repeat this for your left eye, close your right eye and stare at the "W" as you move closer or farther from the screen. Again, at about a foot away, the X will disappear.
X .....................................................................................W
The "blind spot" is the point at which the optic nerve leaves the eye. Think of it as a cable attached to the back of the eye, carrying all your visual information to the brain. As a result, there are no receptors at the "blind spot".
optic disk
It is responsible for sharpest central vision. Lateral to each blind spot is the Fovea Centralis, a tiny pit that contains only cones. Consequently this is the area of greatest visual acuity, or point of sharpest vision, and anything we wish to view critically is focused on the fovea centralis.
This spot is where the optic nerve and blood vesicles enter the eye and it is called the "optic disc".
The brain compensates for the blind spot. It compensates for it by taking in what is around the blind spot and using that as a reference to put a picture in the brain of what it thinks should be in the blind spot.
a blind spot is when someone stares at the light and it makes a spot in there eye that makes them blind.they call it a blind spot because it makes you blind and it makes a spot in your eye.
At the small spot in each eye where the optic nerve exits the eye, they are no light receptors and therefore no vision. The blind spots are to the outer sides of the field of vision and therefore less critical than if they were close to the center. Also, the blind spot in each eye is compensated for by the other eye for those who have two intact eyes.
its in the optic chiasm which leads to the back of the eye
it is found on the retina

Yep.
The blind spot of each eye is located where the optic nerve leaves the eye.
The blind spot does not have or serve a function. The blind spot is cause by a lack of receptors in the location where a person's optic nerve and blood vessels leave the eye.
Fovea.
the Optic Disk
a part of your eye that you cant see from
