These large lenses sit over the eyes and are activated by today's secret word. Once activated, they allow the user to see in absolute dark conditions for up to eight hours before needing to be turned off for twelve hours to recharge (they will recharge in four hours in direct sunlight). They are not magical and will not be extinguished by anti-magic measures.
The glasses emit a powerful light when active, allowing those around the user to see as if they were holding a powerful lantern. The light also attracts wandering monsters at twice the normal rate.
