Ergonomics. Accessible design. Specification of age-related luminance contrast for coloured light1 Scope This International Standard specifies the age related luminance contrast of any two lights of different colour seen by a person at any age, by taking into account the age related change of spectral luminous efficiency of the eye. This International Standard provides a basic method of calculation that can be applied to the design of lighting, visual signs and displays. It applies to light, self luminous or reflected, in visual signs and
