Ergonomics - Accessible designSpecification of age-related luminance contrast for coloured light
Organization:
JSA - Japanese Standards Association
Year: 2013
Abstract: This 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 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 displays seen under moderately bright conditions called photopic vision and whose spectral radiance is known or measurable. It does not apply to light seen under darker conditions called mesopic or scotopic vision.
This Standard specifies the luminance contrast for people aged from 10 to 79 years who have had no medical treatment or surgery on their eyes that may affect their spectral luminous efficiency. For the people with various colour vision different from those of majority of people among subjects, alternative luminance contrast need to be defined according to each spectral luminous efficiency. For the people with low vision, other appropriate visual evaluation guidance depending on the luminance contrast is desirable to be defined with consideration for various visual features other than colour vision.
NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.
ISO 24502: 2010 Ergonomics-Accessible design-Specification of agerelated luminance contrast for coloured light (IDT)
In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
