Do you see Albert Einstein or Marilyn Monroe? If you answered the father of theoretical physics, then congrats! You have a healthy pair of eyes. But if you see a Hollywood actress, it might be time to get glasses.
The optical illusion created by Massachusetts Institute of Technology helps to determine vision impairment. The image was created by superimposing a blurry picture of Monroe over a lightly drawn picture of Einstein.
Healthy eyes should be able to pick up the fine lines of Einstein’s face and ignore the blurry image of Monroe’s.
The image shows that high spatial features like the little details of Einstein’s face are visible when viewed close up, but features with a low spatial frequency like the blurriness of the Hollywood pin-up are only visible at a distance.
ASAP Science posted a video on Youtube explaining the process.
“Up close, we’re generally able to pick up fine details like Einstein’s mustache and wrinkles. But as the distance increases, or if your vision is poor and creates a more blurred image in the first place, your ability to pick up details fades away," the video said.
