Everyone has it: The blind spot of the eye is referring to a spot in your vision that you can't actually see. The brain has to use information from the other eye to fill the this gap. The back of the eye has photoreceptor cells, but those cells do not cover the entire back of the eye, therefore leaving a gap. I imagine that a google search would show a website that could demonstrate this blindspot for you.

End of optic nerve: At the back of the eye, all of the nerve fibers come together to join at the optic nerve which carries the picture to the brain. Strangely, there are no light receiving cells over the end of the optic nerve, so it leaves a blind spot in the vision. However, the brain "imagines" what it expects to see in the area of the blind spot, so we are not aware of this permanent hole in the vision.

Optic nerve: Where the retinal nerve fibers exit the eyeball through the optic nerve, there is a blind spot in the visual field of all patients. It is quite small normally and difficult to detect without formal visual field testing.
