Abstract : Coloration limits for inclusion in the new Australian Standard for sunglass lenses are investigated. Signal visibility ratio R, the normalized ratio of red to white light transmitted by the lens, is considered to be a suitable form of specification. An additional limit is proposed for transmittance in the blue-violet region of the spectrum. (Author)
