I'm looking through Gary Gilmore's eyes

Some advice to glasses wearers - get one of those little screw-driver jobs and tighten the screws which hold the lenses in the frames. Go on - never mind whether they're looking loose or not, just give 'em a twist.

Otherwise, a lens will drop out of your prescription sunglasses without warning and, if you're moving at a brisk pace, you'll tread on it before you realise what's happened.

Bollocks.
