An emergency vision apparatus comprises an inflatable enclosure to enable a user to see through the enclosure when expanded and observe a source of information at a distal end of the enclosure while smoke or other particulate matter is in the environment. The enclosure includes an opening configured for insertion of a user's hand into the interior of the enclosure to allow the user to operate a touch sensitive screen or hardware visible through the second clear member disposed toward a user and a sealable closure for closing the opening and sealing the opening around the user's hand. The sealable closure includes flexible first and second sheets covering the opening, the first and second sheets including respective first and second slits disposed transversely to each other, the first and second slits being configured to allow insertion of the user's hand into the interior of the enclosure.
