After Images are an optical illusion that can be described as an image continuing to appear in one's vision after the exposure to the original image has ceased. A common form of after images is the bright glow that seems to float before ones eyes after looking into a light source for a few seconds.
Within hallucinogen usage, still overlayed images of moving objects are commonly left in place of where the object once was. This creates a series of overlayed images across one's visual field which become less distinct the further they are away from the moving objects current position. Another manifestation of this effect can be described as being able to see the external environment for several seconds after one closes their eyes before it gradually fades away.
