I still remember the day I got my first pair of glasses. I’d been sitting in my grade four class the day before watching a slide-show on mining, from the fourth row in the room. When the teacher asked me (yeah, I was the teacher’s pet) if the image was in focus I kept saying no. It was all blurry to me! The next day, when the doctor checked my eyes, it turned out that my first downy facial hair had been accompanied by major-near sightedness. He couldn’t believe I hadn’t realized there was something wrong—little did he know I spent most of my time with my nose in a book, and as long as I could read print, I thought I was seeing just fine.
