It's also a bugger getting spectacles that fit.
It's also a problem for me, but for different reasons. My head is too narrow. Usually childrens' glasses

Similar here, with eyes set so closely together that I can't use a pair of binoculars (the two eyepieces, even at the extreme adjustment, are too far apart) and my glasses slip down the bridge of my nose. Trust me, folks, my wife has already made all the jokes about narrow-mindedness.
