Have you ever thought about optical illusions? Do our eyes do tricks on our brain?
To understand optical illusions, we must keep in mind that illusions affect our brain, not our eyes.
The visual system is made up of several moving parts
Although the eyes play a major role in seeing optical illusions, they are just one component of a larger visual system that includes many different parts such as the optic nerve, the optic chiasm, the visual cortex of the brain and many others.
We see when light enters the eyes and focuses on the retina. The cell in the retina converts light into an electrical signal that is then sent to the brain via the optic nerve. Well, it seems like we see with our brain. This complex process takes only one tenth of a second.
Optical illusions take advantage of short paths in the brain
Our eyes receive a lot of visual stimuli during the day. To make sure our brains are not overloaded with visual information, they often take shortcuts, filling in blanks or creating an image from previous experience.
Very often we do not notice these changes. We only notice them when we see optical illusions. Optical illusions take advantage of short distances and deceive our brains, so that the image we see is not the same as in reality. Optical illusions can deceive us, but it reveals a lot about how our visual system works.
Do not let your eyes lie to you
f someone shows you an optical illusion and you cannot follow its movement, i.e. it is static, you need a mandatory subspecialty checkup that will see the back segment of the eye and find out where the problem is.
If there is one thing we have learned from the blog, it is that nothing is as it seems. The same goes for your eyes.
