In 2nd grade, I started wearing glasses but, of course, I could not wear them when I went swimming. For well over a decade I thought it was blurry whenever ANYONE (with good eyesight or not) opened their eyes underwater. I believed that the pressure of the water directly on one's eyeballs caused the blurriness.
