This is an optical illusion that might tell you if you need to get your eyes tested. Look at this picture. If you have a decent eyesight, you should be seeing Albert Einstein. In case you see Hollywood actress Marilyn Monroe, you need glasses for sure.
Want to see how good your eyesight really is? Now get up and walk away from your computer screen. Your eyesight is awesome if you can continue to see Albert Einstein even from a decent distance. Try this exercise with a couple of friends and you will know how healthy is your eyesight.
This optical illusion was created by neuroscientists at the Massachusetts Institute of Technology. In a recent video, AsapScience highlighted the process behind the trick.
