Dr. Aude Olivia from the Massachusetts Institute of Technology (MIT) produced an image that could tell how good your eyesight is. Now, ASAPScience has made a video which exhibits the effect of the image. The video explains that if a person is at a normal distance from the image and has decent eyesight, then the person will see Albert Einstein in the image. But, if the person sees Marilyn Monroe in the image then the individual must see an optometrist.

The illusion effect created by neuroscientists at the MIT provides clues as to how a human brain processes details in images or scenes. The ‘Marilyn Einstein’ created by ASAPScience appears first as small and blur photo of American actress, model and screen siren, Marilyn Monroe. When the video provides closer view of the image, the person in the photograph changes and becomes physicist Albert Einstein.

The optical illusion could be helpful in telling about an individual’s vision problems. The MIT team conducted a number of tests where they showed participants the hybrid image for different lengths of time. According to the results of the tests, participants who were unable to pick out the fine details of Einstein's face need glasses.

The image of Marilyn and Einstein also shows how the human brain processes visual information. According to Dr. Oliva, the images not only reveal vision problems, but can be helpful in understanding how the brain processes information.

According to reports, a human brain prioritizes different details within a photograph. If a person views a photo only very briefly, the person left with ‘low spatial resolution’ information.

The video was posted by ASAPScience, which also explains that if a person is at a normal viewing distance from the screen, then the individual should see Albert Einstein in the ‘Marilyn Einstein’ image.
