The wife's favourite sunglasses. The lenses had become badly scratched but we'd kept a few old pairs for spares and I managed to find old pair from with similar sized, unscratched lenses which fitted to the old frame. Thirty mins or so fiddling around removing and reinstating tiny screws, washers, nuts etc. and she has a nice 'new' pair of sunglasses and I have my weekend brownie points.
