I recently got a new eyeglass prescription. Two things had happened to my eyeballs. All of a sudden, I needed reading glasses, first for ingredient labels and the small print on prescription bottles, and then for reading regular text. The second thing was that I could see farther better without my previous near-sighted correction than with it. Thinking this trend might be leading to x-ray vision, I put off a visit to the optometrist for awhile. When I finally made the appointment, the doctor casually told me that it was normal for vision to flip from near-sighted to far-sighted, “especially as we age.” My dream of x-ray vision in time for the summer beach season was dashed upon an horizon I could now see more clearly, even without glasses.
