The light patterns when rubbing your closed eyes could likely be phosphenes (https://en.wikipedia.org/wiki/Phosphene) by mechanical stimulation.

Those have intrigued me for a while. I have some but likely triggered electrical stimulation. Sometimes triggered by a sound while half asleep.



This is a really cool part of the wiki page:

"A possible use of phosphenes as part of a brain to brain communication system has been reported. The system called BrainNet, produces phosphenes using transcranial magnetic stimulation (TMS). The goal of the research is to connect thoughts brain to brain using a system where signals are detected using electroencephalography (EEG) and delivered using transcranial magnetic stimulation (TMS). An experiment was conducted with 5 different groups, each contained three people. The subjects were split into two groups. Two subjects functioned as the senders, and were connected to EEG electrodes, and a third person functioned as the receiver, who wore the TMS helmet. Each person was stationed in front of a television screen with a Tetris-style game. The senders had to determine if there was a need to rotate the falling blocks, but without the ability to rotate them – only the receiver was able to perform this operation. At the edges of each screen, were two icons with two flashing lights in two different frequencies, (one at 15 Hz and the other at 17 Hz). The sender focused on one icon, or the other to signal that the block should be rotated to the right or the left. The EEG produced a unique signal, which was transmitted to the TMS helmet of the receiver, who perceived phosphenes which differed for the 15 Hz and 17 Hz signal, and rotated the block in the relevant direction. The experiment achieved 81% success.[27] These results could eventually lead to mind-to-mind communication technology"

Does anyone know if other research into this method has been explored yet?


You should probably not do this. A key cause of keratoconus seems to be excessive eye rubbing: https://en.wikipedia.org/wiki/Keratoconus#Pathophysiology


> A key cause of keratoconus seems to be excessive eye rubbing

Your link does not say that. Nor does any other that I could google in 10 minutes, including not Mayo Clinic.

I have ophtometrist in the family, and the constant "do not rub your eyes" is burnt into my brain. Be gentle with your eyeballs, they do not like pressure. I get phosphenes from brain signals, most of the time sound triggered.


Some people visualize when they keep their eyes closed for long periods. Some don't.
