I'm noticing something worrying, here. My close-up vision is starting to go. It's not much, just when something is shoved real close to my eyes.
Things get out of focus when they are four or five inches from my eyes. Not bad, in fact, I'd bet, better than most, but from someone who is used to being able to focus on things at about half that distance, it's depressing.
Also I've noticed that it's a little worse in my left eye than my right eye.
I'm getting old.
