Multispectrally tested, printed colour vision test for the fine evaluation of the degree of deficiency

Described is a printed colour vision test for differentiation of three colour vision deficiencies and quantitative evaluation of the degree of deficiency. The test is made on a photographic paper using professional ink printing and multispectral analysis for ensuring feedback. It allows to evaluate the level of red-green (protan and deutan - type) deficiencies at five levels, as well as the level of blue-yellow deficiency at two levels. The fine-scale test plates are also intended for the needs of colour vision screening. Three different types of cards had been created. The psychometric analysis is applicable to the testing results for red-green deficiencies.
