The main function of the human eye is to detect light.
The human eye can be compared to a camera because it has a lens that focuses light onto a light-sensitive surface at the back of the eye, similar to how a camera lens focuses light onto a film or digital sensor.
The blind spot is where the optic nerve exits the eye and there are no sensory nerve cells; this area does not detect light.
The blind spot is located at the back of the eye, where the optic nerve exits.
