I used to do that all the time. Its hard not to try to use your actual eyes. One thing that helps is focus on your "third eye area" the first time I saw the strobe effect (bright flash) was cus i was trying to find the spot where i wasn't straining my eyes but still "looking" with them. It put pressure on that spot and i got the effect.
Hi
When u experienced the strobe affect eas it a bright flash or a blinding flash?
Hi
