Bizarre Optical Illusion

Stare at the white dot on the nose in the negative. Do this for 15 seconds. Don't look anywhere else, just the white dot. After 15 seconds, look at the blank space to the right of the photo. Can you see it?

Don't be afraid, this is not something to scare you. This illusion is known as a 'negative afterimage' and caused by fatigue colour receptors in the back of the eyes and brain.
