That very idea is foreign to me. My eyes are -7.5 (left) and -9.0 (right). My glasses go on before I stand up in the morning and only get taken off as I nod off to sleep at night. They are never anywhere other than on my face or on the bedside table. If the cats knock them off the bedside table, though, there is a serious problem.

I do tend to wander around a bit lost after a shower, though, if I've put them down 5cm from their normal spot.
