the Walnut Diary

This missive is for those over forty with bifocals. Younger eyes need not read further.

You know how you want to check your mail but all sets of glasses are too far away and you decide to gut it out bare-eyed? Ever try to do it while drinking from a large coffee mug?

No kidding: the interference lines around a coffee mug can be made to work as an emergency eyeglass lens. Maybe it only works because of the self-illuminated screen, but it’s very easy to move the cup to where the interference lines produce a lens effect around the rim of the cup, and if you can’t make out letters and words with that, you’re not much of an improviser.
