EYE-STRAIN AND THE CINEMA.
A committee appointed by the IJluminating Engineering Society •of England to inquire into eye-strain resulting from watching the movies has just made its report, which is published m the " British Medical Journal." The committee finds that the chief strain on the eyes comes from the pictures being shown too high up, so that the eyes of the spectators m the front rows have to be raised.
