Illusions

Hey Everyone! You may have received several messages like a picture wherein there is an illusion of rabbit and duck.
You may have came across several illusions. Illusions occur not only in '.JPG' files but also in day-to-day life.

Now look at this image.

.

Do you see that it sets in motion.

Now, you see it by closing your eyes half!

Does it revolves??

No.( For some it might) 

Why does this happens??

The above image is an example of  Motion Illusion. It is a type of optical illusion. The optical lobe of our brain receives the information from the eye, where this image is projected in Two-Dimensions. The effect of the illusion depends on the person i.e. how he/she perceives it. But illusions might be very harmful to a person, psychologically. Indirectly, it may be physically hazardous. This class of Psychological disorders are called Schrizophrenic disorders, where a person suffers visual hallucinations(here we are talking about optical illusions,that's visual hallucination.But hallucination is of different types). Sometimes illusions are also used in psychotic therapies. Also magicians do illusions. 

That's all for today, thanks for reading and subscribe my blog. Thank You.☺
