If you are able to make out both the personalities then your eye sight is good, but if you are able to see Monroe but not Einstein then there are chances to get eyeglasses.
The video is released by ASAP.
The hybrid image is made of two different images where one of the images is having dense pixels and the other is having fewer pixels.
In this hybrid image Einstein’s image is having dense pixels highlighting wrinkles and mustache and the Monroe’s image is having few pixels highlighting only the basic features.
Einstein’s image is clear with high spatial frequency and the Monroe’s image is blurred with low spatial frequency.
People who are unable to make out details of Einstein will never be able to see it.
Once the image gets bigger, one should make out Einstein’s details and can see Einstein in the image and the Marilyn’s image fades.
