1. The Herring Illusion

In the picture, it looks like the lines are curved, but they are actually straight and parallel. What’s so amazing is that the reason we possibly see it that way is because we’re actually seeing into the future. Really.

It all comes down to how the brain perceives sight. When light hits your retina, there is about a one-tenth of a second delay before the brain turns that signal into a visual perception.

The thing is, the human brain has evolved so it compensates for the delay, so the visual system creates an image about what will happen one-tenth of a second into the future. This ability is the same one that allows us to maneuver through a crowd or catch a fly ball.

2. Ponzo Illusion

Would you believe me if i told you that the two figures in the image on the left and the two black lines in the picture on the right are the same size? Well, since you’re reading a list about optical illusions, then there is a good chance that you do believe me, but go ahead and measure it any ways.


The illusion is caused by something called linear perspective , which happens because we see the world in three dimensions. If two lines are converging, in the case of the picture it would be the walls, our brain interprets the lines as staying parallel and receding into the distance.

3. The Pinna Illusion

For the picture in this entry, what is the design? It looks like spirals, right? But they are actually perfect concentric circles. If you don’t believe me, trace your fingers over the circles and you’ll see that they are round and never intersect with one another.


The illusion shows the difference between what the eyes see and what the brain recognizes. What the visual system is trying to do is figure out what pieces are part of the same object.

4. Illusory Motion

In the above picture, nothing is moving. It’s not an animated GIF or a video; it’s just an illusion that induces motion called illusory motion. While it is a common optical illusion, no one is really sure what causes it.

One school of thought is that involuntary eye movements make objects near what you’re fixated on look like they are moving. The other possible reason is that it’s caused by motion detectors in your visual cortex.

When you look around the picture, the detectors get confused because of the constant changes in the image, so your brain thinks that it’s seeing motion.

5. Color Constancy

Looking at the picture above, what colors are squares A and B? They should be gray and white. Now, place your finger in between the squares and look at the squares once more. They are both gray, right?

The reason your eyes see the color(s) that way is similar to the internet phenomenon “The Dress” where some people saw a black and blue dress, while other people saw a white and gold one (in reality, it was black and blue).

The leading theory on why people see colors this way comes down to the way that humans evolved. Our eyes are meant to see color in the daylight, so they see objects in context . When you’re looking at something, light goes into your eye and different wavelengths correspond to different colors in your eye.

Wow!!!!!

Which kind thing be this one now... Sometimes, it's good not to know something than knowing something.

Awesome. This proves how easily our senses can be misled. Trust everything you see at your own risk.

How this one talks help me life

Number 3

Like if you still saw grey and white

For those that don't understand, this is what the op meant:

Only no 3 did it for me, the rest oh em meh, nice one op

Sorry OP, what course will one study to know all these jargons?


and also next time let it be images up and explanations below it.

This is Sorcery!!!!!

The more you look, the less you see

open your eyes slightly and you'll solve no 1.. That number 3 tho

nice

Even this picture itself is of optical illusion.
Take a look at the lips and you'd find a closed one.
Look at it again and you'd find a scared man's teeth.

U might be right
