weird. i wonder if this is what causes my eye pains. occasionally i get this annoying sensation in my eyes that can be almost painful and it makes me walk around squinting all day and sometimes it gets to the point where i have to close my eyes and touch them becaus it the only thing that relieves it somewhat. and come to think of it the last time i got it was during a period of heavy psychedelic usage. it got better after i changed the lightbulbs in my room to blue, green and black. its a lot more soothing for my eyes and helps them feel normal, even though anyone who sees em complains it hurts their eyes haha. Mine lasted for about a week though so i have a feeling its probably completely unrelated
