Over deze norm
This international standard specifies 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 that is applied to the design of visual signs and displays. It applies to lights seen under moderately bright visual environment called photopic vision and whose spectral radiance is known or measurable. It does not apply to lights seen under darker environment called mesopic or scotopic vision. This international standard specifies the luminance contrast for people ranged in age from 10 to 70 years old who have had no medical treatment or surgery on their eyes that may affect their spectral luminous efficiency. This international standard does not apply to visual signs and displays seen by people with colour defects whose spectral luminaous efficiency is different from those with normal colour vision.
