Entoptics coloursThese entoptic moving shapes are just some of the psychedelic patterns we try to describe after a Pandorastar lucid strobe light session.. I have researched the history in Ophthalmics and Physics from Jan Purkinje and Helmholtz from the 1820s who called them ‘Shadow Patterns’ and ‘Form constants’ . They made illustrations of the types of patterns in categories commonly shared amongst experiencers inducing them by simply waving their fingers over their closed eyelids with a gaslamp behind them ( could also be done with the sun )

In ophthalmology, eye floaters are generally regarded as harmless vitreous opacities. They are “entoptic phenomena”, viz. optical phenomena which are caused by certain conditions of the human visual system. Entoptic phenomena, whose appearance can be manipulated by selectively induced changes of consciousness states, are objects of interest for both science- and spiritually-oriented researchers. As physical and neurological symptoms, they belong to the physicians’ area of study; as subjective light phenomena they are likely to gain spiritual meanings for some people. While the Western medical study of entoptics has a tradition of a couple of hundred years, the interpretation of entoptic phenomena like floaters as spiritually significant perception in connection with altered states of consciousness possibly originated in the early days of human art.

The diagram below from Lewis-Williams and Dowson in the 1980s further shows the similarity with San Rock art engravings in caves and the more modern archetypal forms we know from Kluver and Smithies mescaline research in the 1920s-1950s
