Optical illusions drive me crazy. I don’t know why but I can never focus on them properly and, whilst everyone else seems able to spot the hidden picture instantly, I have been known to spend ages looking and still see nothing.
This particular illusion, I eventually got but I nearly was ill in the process. That takes nothing away from the test which is absolutely brilliant, it probably says much more about my eyesight.
I have been avoiding it for a long time, trying to deny that I need glasses but perhaps the time has come.
It will be interesting to read the comments on this one, and see how many of our readers can see the hidden image. Let us know how you got on.
