Got out of the car to go to the bank. Right lens dropped out of my reading glasses. Made using the ATM awkward, squinting with one eye shut.
Next to SpecSavers for repairs. They found a suitable screw to replace the one that fell out, then checked the tension of the others screws, putting a dab of Loctite on each one. Next the nose-pads were replaced & the lenses cleaned in an ultrasonic bath before being dried & returned to me.
