Your Brain Fills in the Blind Spot
Each eye has a point with no photoreceptors, yet everyday vision usually feels seamless.
Your visual field has a blind spot, but your brain usually hides it from you.
The optic nerve exits through the retina at a point without photoreceptors. Rather than showing a blank hole, the brain blends nearby visual information into a coherent scene.
It is a small everyday reminder that perception is constructed, not simply recorded.
