lol, I doubt this has anything to do with shortsightedness. Seriously, what's the basis for coming to that sort of conclusion?

If someone is severely short sighted they might only get a blurry view of the image, which would cause it to be perceived as Marilyn Monroe.

A sharp view of the image will cause it to be perceived as Albert Einstein.

In effect, the image is a superimposition of two processed images:
A severely blurred image of Marilyn Monroe (high spatial frequencies removed)
A severely edge enhanced image of Albert Einstein.

Here's my attempt:

There is probably a more advanced way to tune this, by using a slightly different convolution kernel for blurring/sharpening that actually uses the way images change as they defocus, but your attempt is surprisingly good. What filters are you using?

Photoshop
Gaussian blur 3.5 pixels
High pass filter 4.5 pixels

I've no idea what the actual kernels are. It probably would work better if:
a) The images were matched for contrast prior to convolution
b) The kernels had a flat MTF when combined.

I just chose my particular parameters, because the blurring looked 'about right' and then I tweaked the HPF until it seemed to be OK. Took about 2 minutes.

Nothing mind blowing about this. The details become less apparent the further you are away from the picture, and looks like a different person. Big deal.

nothing mindblowing about this? seriously... nothing like, say, the point where your optic nerve... and your brain make a switch, seriously.. fuck.

I saw this a while back and realized that it has more to do with the size than the distance. It was a thumbnail and it looked like MM and now, much larger, it looks like AE. Same PC and chair.

So the take away lesson here is that the world is full of beautiful women if we are just willing to take off our glasses.

"Men don't make passes at women while wearing glasses."

Or look at them from a far enough distance.
