The blind spot is where the optic nerve and blood vessels leave the eyeball. The optic nerve is connected to the brain. It carries images to the brain, where they're processed. This is how we know what we're seeing. Our eyes see the object or image, and our brain interprets it.

Alternative Title: optic disk

Blind spot, small portion of the visual field of each eye that corresponds to the position of the optic disk (also known as the optic nerve head) within the retina. There are no photoreceptors (i.e., rods or cones) in the optic disk, and, therefore, there is no image detection in this area. The blind spot of the right eye is located to the right of the centre of vision and vice versa in the left eye. With both eyes open, the blind spots are not perceived because the visual fields of the two eyes overlap. Indeed, even with one eye closed, the blind spot can be difficult to detect subjectively because of the ability of the brain to “fill in” or ignore the missing portion of the image.
