I’ve worn reading glasses since kindergarten, so it was a very big adjustment for me when I switched over to contact lenses in my late-20s. I’d spent over twenty years putting on my glasses whenever I needed to work...whenever I needed to concentrate. In fact, it was difficult to learn to focus without first putting on my “thinking cap.” Then, a few years later, it was actually a relief when my eyes worsened, and I needed reading glasses again and I could return to the security of my thinking glasses.
