While I was living in New York City a few years back, I heard a story from a friend about eyes that stayed with me since. She said that a native American man came to the city once and realized how hard and unnatural the streets are on the human eyes. He explained that people are meant to gaze at far away horizons at least once a day and knowing that, he wondered how people can live in a big city where all impressions bounce back into their eyes at such close distances. In the metropolis our eyes work overtime on our behalf when we cross the street, walk on the pavement, dodge passersby and even at home in front of our fast-moving screens of impressions.
