Everyone has a blind spot. The area of the retina without photoreceptor cells is called the blind spot, where the optic nerve passes. There are no visual cells in this place, and the image of an object falling here cannot cause vision. Since the optic nerves of the human eye are in front of the retina, they converge at a point through the retina and connect to the brain. If the image of an object happens to fall on this point, it will not be seen, which is called a blind spot.
"Because you're always in my blind spot, so I can't always see you."
"Then are you blind... Why can't you see me no matter where I stand?"
