Description

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 relative luminous efficiency of the eye.This basic international standard provides a method that can be applied to the design of visual signs and displays. It applies to visual environments in which the spectral radiance is known or measurable and viewed under the moderately bright light level called photopic vision. It does not apply to those which are seen under a dark environment called mesopic and/or scotopic vision.NOTE 1 This document specifies the luminance contrast for people from 10 yrs to 70 yrs of age who have had no medical treatment or surgery on their eyes throughout their life. For people younger than ten years old or older than 80 years old, this document may apply by estimating the age-related spectral luminous efficiency by extrapolation.NOTE 2 This document does not apply to visual signs and displays seen by people with colour defects who have different spectral luminous efficiency from people with normal colour vision.
