'''Tracers''' are the experience of trails of varying lengths and opacity being left behind moving objects in a manner that is similar to those found in long exposure photography.<ref>Visual Trails: Do the Doors of Perception Open Periodically? | http://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.1001056#pbio.1001056-Horton1</ref> These can manifest as exactly the same colour of the moving object which is producing it or can sometimes be a randomly selected colour of their own.

A relatively consistent way to reproduce this visual effect is to simply move one's hand in front of their face or throw an object under the influence of a moderate dose of [[psychedelic|psychedelics]].

#'''All-encompassing''' - At the highest level, a person’s visual field has become so sensitive to the creation of tracers that it entirely smudges and blurs into an all-encompassing tracer at the slightest movement of an object or the eye. This can make it extremely difficult to see unless one's eyes are kept still in a motionless environment as tracers linger almost indefinitely or until one looks elsewhere within their visual field.

Tracers are often accompanied by other coinciding effects such as [[drifting]] and [[after images]].
