Aurospecs



Aurospecs was a trade-name for frames (or goggles) that featured Kilner screens as their lenses, first offered for sale by Harry Boddington and the London Psychic Educational Centre in the 1930s. According to the advertising copy, the lenses were neither coloured glass nor gelatine, but "optically perfect glasses cemented together, enclosing a specially compounded solution of alcoholised dicyanine," thus having a limited life-span, as the chemical dyes would evaporate and lose colour over time.

A similar product called Kilnascrene was also sold by the London Psychic Educational Centre and the Psychic Stores.
