This was not the first time I made a mistake like this. When I was a kid, I had trouble seeing my teacher's blackboard. I just kept moving closer to the blackboard. I saw a doctor when I had trouble understanding what the teacher was writing from the first row. Until I read this, I had forgotten about my own history of mild myopia: I had a mandatory eye exam at 14, which detected the problem, but I was too vain to tell my parents about it, because I didn't want to wear glasses. 3 years of straining to read the board in class followed (which probably dropped my performance in school significantly). When I turned 17 and wanted to drive, I caved and got glasses and contacts. It was an amazing change in quality of life, and by the time I was 22 I had LASIK. Thanks for reminding me of this: I'm going to make sure I get my own kids' eyes tested at least annually.
