Rumor has it that not many people are able to solve this odd-one-out puzzle in less than 10 seconds. Would you care to give it a try?

Is 20/20 Perfect Vision?
20/20 vision isn’t necessarily perfect, but it’s pretty darn good. As noted above, 20/20 is really just normal vision. The score means that at a distance of 20 feet, you can see clearly what you and other people with normal vision should be able to see clearly at 20 feet. Hence, “20/20.” About 35% of adults in the U.S. have 20/20 vision. When you add in those who have 20/20 vision when wearing their eyeglasses or contact lenses, that number jumps to 75%.

It’s actually possible to have better than 20/20 vision. People with visual acuity scores of 20/10, for example, can see clearly at 20 feet what a person with normal vision would have to be within 10 feet to see clearly. There is even one recorded report of a person with 20/5 vision, but most researchers question the authenticity of that report.
