Varifocal Formations

Cloud formations in the shape of the UK/GB are all the rage at present. I snapped my own yesterday morning in the sky over Chipping Sodbury:

For some time now I thought I had scratches on my varifocals - either that or some smudge that I couldn't remove. Got Hay to have a look as, without my glasses, I can't see things close up. It transpires that my lens prescription is etched into the lenses. Apparently it's common practise with varifocals.

Why this should be done only with varifocals is a mystery.
