<P> A blind spot , scotoma , is an obscuration of the visual field . A particular blind spot known as the physiological blind spot , `` blind point '' , or punctum caecum in medical literature , is the place in the visual field that corresponds to the lack of light - detecting photoreceptor cells on the optic disc of the retina where the optic nerve passes through the optic disc . Because there are no cells to detect light on the optic disc , the corresponding part of the field of vision is invisible . Some process in our brains interpolates the blind spot based on surrounding detail and information from the other eye , so we do not normally perceive the blind spot . </P>
