A laboratory study may help you to determine the location of your visual blind spot, but you will not notice it outside of the laboratory because .

blind spot will not impair your vision

Explanation:

Blind spot may be defined as the point of our eyes where the optic nerve leaves our eye, which creates a "blind" spot as none of the receptor cells are located there.

A blind spot can only be studies in a laboratory because blind spot does not impair our vision. The blind spot falls on nose side of our retina, that means that the objects to our right side falls on the right eye's blind spot and objects to our left may fall on the left eye's blind spot. Thus, the blind spot  normally does not impair our vision, since our eyes are moving and because our one eye catches what the other eye misses.
