If I can’t read the signs in life, do I need glasses?

A man was missing all of the obvious signs, stubbornly insisting that he knew more about eyeballs than his ophthalmologist (his eye doctor). Although he was a skilled photographer, his knowledge of lenses had more to do with exposure, chiaroscuro, and depth of field, not sphere units, plano, or that mysterious «OD,» «OU,» or «CYL» reading on your glasses prescription. 

This lens expert rushed to Reddit’s deepest corners, finding hilarity and storytelling solace on r/MaliciousCompliance to share his story of customer foolishness. Even if you know optics and lenses as it pertains to cameras and photography, that doesn’t mean you know diddlysquat about eyeballs. He can certainly see that clearly now… Or maybe it’s still blurry because his lens prescription is totally wrong.
