Some enchanted evening

"The frame was pretty. It was another lucky thrift-shop find I'd added to my collection; a simple and rather dainty cateye frame in pale, silvery blue aluminium. The lenses were anything but pretty. Or simple. And definitely not dainty. / The silence lasted through Betty's Bay. / 'One of my colleagues in the jewellery business collected vintage eyeglasses too.' / 'It's more that they often work better than most contemporary frames for my prescription. That's what I was saying. With these, the lenses are smaller and rounder than they appear, and my eyes are well centred. That makes them much thinner and lighter.'"
