At present there appear to be no controls on the amount of coloration per se in sunglasses, motor vehicle windshields, etc. This paper shows that spectrally neutral grey lenses and windshields should have no effect on the perception and recognition of red traffic signal lights, in contrast to the detrimental effects expected for the use of certain coloured lenses and windshields. Allowable coloration limits are derived quantitatively, and a recommendation is made that the sale and use of coloured lenses and windshields should be regulated by legislation. (Author)
