Hi Andy, there have been different times when I have experienced these strong geometric patterns which are very intense in colour, that move across the full width of my eye, mostly the left eye and more recently, my right eye for the first time…but no feelings of discomfort with this phenomenon. Perhaps and only perhaps, your system is trying to balance out the input of these higher energies which may be causing the discomfort to you, only a thought on my part though. 🙂
