I’ve never looked up this statistic, but I’ve got to think that by the end of our lives, at least 80% of us wear glasses for some portion of them. For some of us, it starts early. I got my first pair before I was six years old. I remember getting them midway through kindergarten. And it was one of those revelations where I could finally see the blackboard clearly. But like most kids, wearing them isn’t fun. Losing them, breaking them, and just the annoyance of wearing them all the time make it difficult. Rumors have it that smart glasses are set to replace our smartphones. Many think that’s a good thing. I doubt they started wearing them at a young age…
