Glasses are something that comes with age for the vast majority of us. I started wearing glasses in my late 40's for reading. Although I could still read magazine size print without them, wearing them made it easier and clearer.
I'm 65 now, and I wear glasses to read with, and to mess around on the computer. I wear them to watch TV and to drive, about 50% of the time, as I actually don't need them to do either, yet, but that day is coming.
Like I said, it happens to the majority of us at some point. Don't ignore it, but don't be overly concerned about it, either.
