Lack of light-sensitive cells

- The lack of light-sensitive cells causes a blind spot. Without light-detecting cells, your eye can’t transfer messages about an image to your brain, and your brain can’t interpret the image for you. As there are no cones or rods at this point on the retina, you have a small gap in your visual field.

Nov 9, 2022 · A blind spot is a very small gap in the visual field of each eye—an area of your relatively nearby surroundings that you can't see. It may sound like a physical defect, but everyone has a small natural blind spot (physiological blind spot), and it's not usually noticeable.
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.
Apr 11, 2018 · The blind spot is where the optic nerve and blood vessels leave the eyeball. The optic nerve is connected to the brain. It carries images to the brain, where they’re processed....
Jan 18, 2023 · Scotoma (pronounced skuh-tow-muh) is the medical term for a visual field abnormality, or a blind spot. Most of these blind spots happen in one eye, but they can happen in both eyes.
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.
Why does this happen? The point where your optic nerves converge to exit the eye and into the brain is known as the optic disc. This area of the eye has no light-sensitive cells to detect light rays. This results in a break in the visual field known as your “blind spot.”
