Your retina is made up of light-sensitive cells which send messages to your brain about what you see. Everyone has a spot in their retina where the optic nerve connects. In this area there are no light-sensitive cells so this part of your retina can’t see. We call this the blind spot.
May 15, 2022 · All the nerve impulses generated in the retina travel back to the brain by way of the axons in the optic nerve (above). At the point on the retina where the approximately 1 million axons converge on the optic nerve, there are no rods or cones. This spot, called the blind spot, is thus insensitive to light.
May 27, 2021 · Every human eye has something called a blind spot. This natural blind spot is the place in the retina — the light-sensitive inner lining at the back of your eye — that doesn’t have any cells that respond to light. The blind spot sits in the part of your retina where the optic nerve exits the eye.
Dec 19, 2022 · A scotoma is generally referred to as a pathological alteration of vision, but it should be specified that there is also a physiological scotoma, the so-called blind spot or blind area of Mariotte; it is a point of the eye where vision is absent, the so-called optical papilla, an area where photoreceptors are absent.

Feb 3, 2020 · There are no photoreceptors where the optic nerve meets the retina, creating a “blind spot.” Our brains fill the gap using information from the other eye. Signals traveling along nerve fibers from both eyes meet at the optic chiasm.
Via processes in the brain, the blind spot is interpolated based on surrounding detail and information from the other eye, so it is not normally perceived. Although all vertebrates have this blind spot, cephalopod eyes, which are only superficially similar because they evolved independently, do not. In them, the optic nerve approaches the ...

May 7, 2018 · Answer: The blind spot is the part of our retina that lacks light-sensitive receptor cells. The back of our eye is called the retina. The retina is packed with photoreceptor cells that respond to incoming light. These cells do not exist in the blind spot.
