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.<\/p>\n
\nThis Standard provides a basic method of calculation that can be applied to the design of lighting, visual signs and displays.<\/p>\n
\nIt 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.<\/p>\n
\nIt does not apply to light seen under darker conditions called mesopic or scotopic vision.<\/p>\n
\nThis 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.<\/p>\n
\nFor 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.<\/p>\n
\nFor 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.<\/p>\n
