Optical illusion

Focus on the dot in the center and move your head backwards and forwards fome the screen. What do you notice???

If you take a look at the following picture , let me tell you … it is not animated. Your eyes are making it move. To test this, stare at one spot for a couple seconds and everything will stop moving. Or look at the black center of each circle and it will stop moving. But move your eyes to the next black center and the previous will move after you take your eyes away from it…. Weird isn’t it???

See this picture for 45 seconds you will see like the insects moving in your hands

look at the three painting on the ground?

It is face or a party

look at the picture upside down?what do you see?

Rubbit or Duck???

Follow the following instructions:

Relax and concentrate on th four small dots in the middle of the picture in

about 30 – 40 secs. Then take a look at any smooth single coloured surface (probably a wall) near you . You will see a circle of light developing

Start blinking your eyes a couple of times and you will see an image emerging!!! WHAT DO YOU SEE??? , WHO DO YOU SEE???

You should see a man’s face… AND a word that starts with letter “L”. Got it????

When you first look at this, do you see and old man with holly around him, or do you see a couple kissing?Be warned. This may take some time to see both “sides” of the illusion

This photograph is actually a composition of black shapes on a white surface, however the mind organizes the elements, based on past experience, into the image of a Dalmatian dog

Count The Faces

Though this image seems too scary at the first sight but it has a lot of things to reveal. Try to concentrate and count the number of faces shown in this picture.

what do you think it will be

use your vision to calculate the number of horses in the image

The definition An optical illusion (also called a visual illusion) is characterized by visually perceived images that differ from objective reality. The information gathered by the eye is processed in the brain to give a percept that does not tally with a physical measurement of the stimulus source. There are three main types: literal optical illusions that create images that are different from the objects that make them, physiological ones that are the effects on the eyes and brain of excessive stimulation of a specific type (brightness, tilt, color, movement), and cognitive illusions where the eye and brain make unconscious inferences. Physiological illusions Physiological illusions, such as the afterimages following bright lights, or adapting stimuli of excessively longer alternating patterns (contingent perceptual aftereffect), are presumed to be the effects on the eyes or brain of excessive stimulation of a specific type - brightness, tilt, color, movement, etc. The theory is that stimuli have individual dedicated neural paths in the early stages of visual processing, and that repetitive stimulation of only one or a few channels causes a physiological imbalance that alters perception.
