You're probably familiar with the Snellen Eye Chart at your eye doctor's office. I once memorized it, thinking that would stop the optometrist from prescribing me some badly needed but oh, so dorky glasses.
It didn't work - he wasn't fooled and I have to wear glasses since fourth grade. But enough about me, feast your eyes on these strange eye charts, courtesy of Dark Roasted Blend: Link - Thanks Avi!
Is there a copy of the doughnut chart somewhere that is higher quality? The link page chart can't be enlarged enough to read the text.
