Why is the portion of the image hitting the blind spot not perceived?

The blind spot in our vision occurs where the optic nerve exits the eye, creating an area without photoreceptor cells (rods and cones). Since there are no receptors to detect light in this region, any image falling on the blind spot is not perceived. The brain compensates for this gap by filling in the missing information based on surrounding visual cues, allowing us to perceive a continuous image despite the blind spot. Consequently, we are often unaware of this missing portion in our visual field.
