Today, I had the misfortune of bending the frames for my glasses when I accidentally knocked them off my face. And, in my case, proper adjustment is critical since I wear progressive lenses. You never notice wearing progressives unless/until they are misaligned. I’ve been fussing with for hours; but they still aren’t quite right. I would have gone to the optometrist; but, unfortunately, they were closed. I don’t generally think about the ravages of time except when something unusual happens like today. Anyway, there still are some activities that I’m fully functional without corrective lenses.
