Your retina, which is a thin layer of neural tissue at the back of your eye, is made up of tiny, light-detecting cells called photoreceptors. When light lands on your retina, it sends electrical bursts through your optic nerve to your brain. Your brain turns the signals into a picture.
The spot where your optic nerve connects to your retina has no light-sensitive cells, so you can’t see anything there. That’s your blind spot.
Why You Don’t Notice It..?
You probably don’t notice your blind spot because your other eye makes up for it.
Each eye sends data to your brain on its own, so your brain fills in what’s missing. What one eye doesn’t see, your other eye does.
Experts aren’t sure how your brain fills in the details. They think it’s a mix of processing what it thinks is missing and reusing electrical bursts around your blind spot.
Like the blind spot while driving, I wonder how much we miss that's right beside us.
Here's an easy way to find your blind spot.
Use the image below these directions.
*"Sit about a foot away from your screen.
- To find your right eye’s blind spot:

- Move closer to the screen, then farther away.
- Keep doing this until the plus sign disappears.
- When it disappears, you found your right eye’s blind spot.
- To find your left eye’s blind spot:

- Stare at the plus sign.
- Move closer, then farther away. Repeat.
- When the circle disappears, you found your left eye’s blind spot.
