Aurospecs vintage glasses with original packaging. Walter John Kilner, M.D. B.A., M.B. (Cantab.) M.R.C.P.,(1847?1920) was a medical electrician at St. Thomas Hospital, London. There, from 1879 to 1893, he was in charge of electrotherapy. In 1911 Kilner published one of the first western medical studies of the "Human Atmosphere" or Aura, proposing its existence. Glass slides or "Kilner Screens" containing alcoholic solutions of variously coloured dyes, including a blue coal-tar dye called "dicyanin" were used as filters in "Kilner Goggles" which, together with lights, were held to train the eyes to perceive electromagnetic radiation outside the normal spectrum of visible light. Clairvoyants and psychics picked up on the usage of these goggles to view auras, and 'Aurospecs' - a cheaper alternative and more widely available - were produced to sell to a public interested in such phenomena in 1930's.
