I just discovered the downside to being 50. I'm at work and I can't find my glasses and I have no idea if I was wearing them when I rode to work this morning. But I do remember getting dust in my eye on my ride. Maybe that's a clue. I wish I could just wear my glasses all the time, but the bottom of the bifocal only works at less than 16 inches and the top at more than 3 feet. Luckily, those (bifocals, memory) are my only complaints about old age so far, unless I'm forgetting a few.
