Spot The Difference

I collected my spectacles yesterday afternoon, after having lenses to my new prescription put in. Since I mislaid one pair I have had two pairs of identical frames so just changed one of them, those on the bottom.

So I was decidedly miffed when, taking them off this morning, a lens fell out. Fortunately it fell on carpet and was undamaged but of course it meant another visit to the Gyle, when I had better things to do.

The assistant fixed it back then spent quite some time, as I was not happy with the alignment, ensuring that the lens had been made to specification and they fitted properly.

I can tell already that they're not sitting level so I fear another visit before the week is out.
