I have had reading glasses since my late 40's, probably the result of too much reading by too poor a light. They get an upgrade every two years as my eyes grow ever weaker and there is no doubt driving glasses will be mandated next time around, though I already have a pair on hand.

But I am thinking now that even this is insufficient. How do I know? Well only just now, I mistook a hot coal that had somehow fallen from the combustion heater (which I didn't see happen) for a toffee wrapper.

Yes, I think that it is time to have my eyes tested again!
