Possible cause image retention

[zipur]

I was reading the forums and found this image as a test for IR on my MacBook.
I watched the image for several minutes and the looked away. To my surprise the image was burned into my eyes. I could see the same image on the wall!
I am not disregarding some faulty screens, but could this be the cause of some complaints.

Maximus this image and then stare at the wall

If you're looking at it the hole time - of course this does happen.

but it doesn't matter - the pic's attached to several posts speak their own language. So the problem is definitively there and not a game between your brain and your eyes...
