There’s a GIF doing the rounds of the internet today and apparently, it can test how good your eyesight is.
Have a look at the below image and if Marilyn Monroe morphs into Albert Einstein as the GIF moves forward, your vision is up to scratch.

The illusion was created by a research team at Massachusetts Institute of Technology, led by Professor Aude Oliva.
It tests your ability to focus and pick up contrasts and the science behind it is explained in the below YouTube video.
