Aurospecs



Aurospecs was a trade-name for frames (or goggles) that featured Kilner screens as their lenses, first offered by Harry Boddington and the London Psychic Educational Centre in the 1930s. According to the advertising copy, the lenses were not coloured glass, gelatine, but "optically perfect glasses cemented together, enclosing a specially compounded solution of alcoholised dicyanine," thus had 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.
