I just recently came across SHAW© Lenses and how their algorithms are supposed to correct for any form of aniseikonia. While I'm trying to interpret the information seriously (though I find it suspect that they define anisometropia as "different prescription for each eye") from this company I've never heard of before, I can't help but imagine how the above photo was taken.
*Photographer*: Okay Melissa, we're going to take a series of pictures. Try looking like you just smelled a juicy fart, then look like you're about to projectile vomit, then look like you're barely hanging on to consciousness. We'll finish with a generic picture of you smiling wearing poorly-adjusted frames, got it?
