According to Lenstore, having perfect vision boosts your chances of identifying the error. But even if you do have 20/20 vision, you may find yourself struggling; one in five people reportedly give up before solving the puzzle. The brainteaser becomes more confounding the longer you stare at it, so here’s a hint: The word you’re looking for is on the right side of the image.

Typos aren’t merely annoying. Throughout history, they’ve been known to cause big—and expensive—problems.

Fortunately the stakes of finding the error in the image above aren’t quite as high.
