Did you know you can hurt your brain by looking at a picture! Warning!!

WARNING! DONT LOOK AT THE PICTURES FOR MORE THAN A FEW SECONDS)

The images below, depict a set of horizontal and vertical lines which have the ability to affect your brain. In 1965, Celeste McCollough discovered the effect and named it after her.

The McCollough effect is a phenomenon of human visual perception in which colourless gratings appear coloured contingent on the orientation of the gratings. If you look closely at the red and green gratings for a number on minutes and then look at the colourless ones, you will see the green and red colours according to the orientation of the gratings. Glancing away from the images you will start to see the grated pattern in your vision. In other words, if you stare at the images for long enough, it will retain in your vision for a number of minutes.

This phenomenon can last from a few seconds, to up to 3 months. It seems quite scary to think that by simply looking at an image, you can temporarily ‘scar’ your eyesight.
