It has been understood that optical illusions, indispensable for the internet, that we need to look at every time we see them, actually deceive our eyes, not our brains. In other words, it is not the experiences and information we have gained so far that mislead us, but only the nerve cells in our eyes.
You may have encountered it once, and you may even be wrong a few times. Which line is longer in the image, which direction does the circle turn, and even what color is this dress, shoes, wall… The debates on optical illusions are endless on the internet. However, these debates also find a response in the scientific world, scientists how our brains or eyes work They use these misleading, controversial images to understand.
Ecologist Joylan Troscianko and neuroscientist Daniel Osorio at the University of Exeter in England; details of an optical illusion, such as color and shape Is it because we see differently or because of the way our brain perceives it? Researched it was related.
For example, the two short gray bars in the image below actually have the same colors:
However, since one is on the white line and the other on the black line, we see the colors of both in different tones. Probably where the left line is darker We get the comment.

The Real Reason We Are Confused Looking At These Optical Illusions
So, why don’t we experience this confusion when we look at a picture like the ordinary landscape below or its reality? Why do we agree that trees are green and the sky is blue?
Because the experiences we had until that day, for example, in our childhood, we were taught that the color in the appearance of trees is called green and its tones. To date, this type has been the main cause of errors in optical illusions. learned situations was shown, but with the new research it became clear that this was not the main reason.

Don’t Eyes Lie? 10 Optical Illusions You’ll Have Difficulty Understanding How
Nerve cells in our eyes compress the image entering through the lens before transmitting it to the brain, just like .ZIP files in computers…
If the image we are looking at is not complex like the landscape, but contains extremely simple details like the images that cause optical illusions, this compression process affects the result more. In other words, our eyes compress the image and messages our brain can read The color of the work changes as soon as it is made. Our eyes err in this compression process, transmitting an erroneous message to the brain. So our eyes are deceived.
Errors can occur as a result of compression in complex images that we often encounter in the real world. However, these errors compared to errors in a simple image more difficult to detect. In fact, for this realization process, someone often has to come up to you and say, ‘Actually, those gray lines are the same color’. As a result, the erroneous message formed as a result of the compression process in our eyes is read by our brain, and this message does not match the reality.

The findings of the research will be used in TV and screen productions with next-generation HDR technology:
It is difficult to call it an optical illusion because it is not consciously produced, but our eyes, HDR (High Dynamic Range) A TV with technology does not always correctly detect the contrast between the darkest and lightest colors on the screen. Even if those blacks are shown as completely black and whites as completely white, resolving this misconception in our eyes depends on the results of the researches like the one above.
In other words, the main problem to be overcome in the production of high-tech HDR displays; not to produce panels that are clearer and more realistic, with higher color accuracy. Colors in these panels panels that present images that can be accurately perceived by our eyes to produce.
