Totally OT (or is it?) but I just got computer glasses. Business glasses, actually, which are for computer work and reading, but not distance. To be distinguished from "office glasses" which are for computer and keyboard (who looks at their keyboard?).
Anyway, to you folks who spend as much time reading and blogging as I do (and you know who you are) and who wear progressive lenses, go out today, get your eyes checked, and order up a pair. It's amazing what a difference they make.
