watch carefully
Pay close attention to the first image that appears on your screen and that, at first, looks like a blurry work of art, like clouds of colors. It is, in fact, an image intended to deceive our eyes. To do this, stare at the center of the image and see how each of the colors begins to fade. Furthermore, a tip for observing the phenomenon is to place your index finger in the center of the image and stare at it until everything else disappears.
In the second image, the phenomenon is easier to observe, as it is enough to focus on the circle in the center of the image. Then, little by little you will notice that the blue border around you disappears, and it will quickly reappear if you bring your focus back to it. This optical illusion is a well-known way in psychology to understand how our perception takes place.
Troxler effect

This is a conclusion that he reached regarding the human perception of objects, as when there is a focus, we tend to mentally ignore the rest of the information at our disposal. around. In fact, this interpretation is not central only to visual perception, but to our human nature as a whole. Since we are beings that work from targets and pre-established points.
