If my eyesight were better, I'd love to try 10-meter competition, but at 50-something, my eyes just aren't what they used to be... maybe we need an online league for, er, grown-ups?

Don't let middle age stop you, just get a pair of shooting glasses with a prescription that puts the front sight into perfect focus. I did that at 44...and should have done so five years earlier.

This is the next thing to explore. I've been fortunate that at 46, I'm just now to the point where glasses are helpful (but not necessary) for reading. I still don't shoot with prescription lenses, but I'm finding my eye begins to fatigue and has trouble keeping a good sight picture. I've looked at customsightpicture before and considered it. Maybe time to re-visit the sight.
