When you look at this illusion, how do the two purple lines act? Are they straight or do they bend?
Because we are drawn to the centre of the image, with the black dot, the purple lines appear to curve slightly. Our focus is on the area of the illusion where the perspective is furthest away and the lines retreat to the dot itself. This means that our brains cannot distinguish between the centre and the main focus of the black circle, and the lines in the foreground.
These line perspective illusions are simple yet effective in tricking our minds.
