I seem to be posting a lot of things about being observant and weird visual effects recently. I am just following internet trends and it is all the fault of that accursed burgundy and Magrathean lilac coloured dress.
This is not an illusion but different people will see different things. This is because people have varying ocular prescriptions. Or to put it another way – some people need better glasses. I am basically giving you a free eyesight test. Have a look at this:
Who do you see in the picture? Albert Einstein or Marilyn Monroe? If Monroe, then you’d better pop to the opticians. There is some quite cool science behind this but it basically boils down to how we recognise faces. The picture is a hybrid image that fuses a detailed picture of Einstein with a blurred picture of Monroe. If you vision is a bit blurred, your brain goes with the overall shape of what is can see – which is Monroe. If you see Einstein, then step further away from your screen, or squint, and you might see him turn into Monroe.
You’re not allowed to just say, “I see dead people.”
I spent thousands of pounds on eye laser surgery and can see Einstein from up to a mile away. I hope you fare as well. This free eyesight test is on the house.
Here is a short video explaining this much better than I am:
