This sheet of nerves is responsible for your vision and what you see and it is called the RETINA. There is a “hole” in the sheet where the Optic Nerve enters the eye. This area is called the Optic Nerve Head. Photoreceptors are cells in the retina that detect light and allow you to perceive “vision”. On the optic nerve head there are NO photoreceptors. Thus, there is no light or vision detected at this spot in the retina. This is your “Blind Spot”. Every eye has a blind spot….your blind spot in your right eye is slightly on your right and your blind spot in your left eye is slightly on your left.
