Recently, I bellied up to a bar waiting for what seemed like an eternity to order my beer. It’s not that the place was busy, in fact the bartender was waiting for me. But I’d forgotten my glasses, so reading the tap list—hung high on the back wall—was slow going, even though it was written in six inch chalk letters. Just before I made my choice, I caught a glance of myself in the back mirror. I was squinting like a sea captain steering through a gale. With wide open eyes, the list would have been unreadable.
Why do people squint to see better? For the longest time, I thought squeezing my eyelids somehow reshaped my faulty eyeballs. And while squinting does slightly change the shape of your lenses, the real answer has to more to do with the back of your eye than the front.
