I assume you are referring to the area on the visual field the represents the optic nerve. The nerve enters the back of the eye and there are no rods or cones (nerve endings) over the spot where it enters, thus the blind spot. It is there all of the time.

Because we have two eyes, the blind spot is not noticeable unless we have one eye closed.

Thought I would add that
