As imagens das embalagens foram adicionadas individualmente na ferramenta, obtendo-se simulacoes para os tres tipos de discromopsia: (1) protanopia ou deficiencia para o vermelho; (2) deuteranopia ou deficiencia para o verde, e (3) tritanopia ou deficiencia para o azul.
Na Figura 2 sao apresentadas as imagens obtidas atraves do simulador, mostrando como as embalagens sao vistas por individuos portadores de (1) protanopia, (2) deuteranopia e (3) tritanopia.
Na simulacao da deuteranopia tambem ocorreram alteracoes nos valores atribuidos as variaveis da cor (tabela 1), especialmente uma reducao nos niveis de vermelho e de claridade, causando uma descaracterizacao do aspecto original da amostra de cor 1.
Otherwise, the software tool named Coblis produced different colour transformations for both dichromacy types, but they were always inaccurate because of the systematic errors found both in [h.sub.uv] (for example, about 140[degrees] instead of 183[degrees] for pseudoachromatic green and protanopia) and [L.sub.R] (for example, [L.sub.R] was over one for the pseudoachromatic reds both for protanopia and deuteranopia, although predicted [L.sub.R] values for protanopia and pseudoachromatic reds were under one).
Table 1 shows the equivalent measurements obtained through the Variantor goggles (distributed by Cambridge Research Systems, http://wwwvariantor.co.uk/) or after each transformation performed by Coblis to simulate protanopia or deuteranopia.
Overall 2.48% of the populations of Quetta had this abnormality with deuteranopia being more prevalent.
Dichromacy occurs when only one of the cone pigments is missing and is categorized into protanopia (characterized by the complete absence of red cone), deuteranopia (characterized by the absence of green cone) and tritanopia (complete absence of blue cone).
For visitors wanting to experience the eye conditions first hand, the vision science research team were on hand with simulators for deuteranopia
, where the vibrancy and hues of a red chilli plant on the table were blended into the background sea of greens.
The Game Update Six will also bring in more options, protanopia, deuteranopia
and trianopia or the colourblind options for Titan Pilots.
The Tibetan study (9) showed 14 (n = 14) cases simple Deuteranomaly, 8 Extreme Deuteranomaly followed by 9 cases of Protanopia, 9 Deuteranopia
, 7 Protanomaly, 3 Extreme Protanomaly and 1 case of Tritanopia.
The number of road traffic control devices in road scenes reported by a group of observers with the color vision defect of deuteranopia was compared with the number reported by observers with normal color vision.
One consisted of 20 men with normal color vision, and the other was 11 men with the color vision defect of deuteranopia. The number of observers provided sufficient statistical power to detect differences between the color-normal and color-deficient observers in the number of traffic signs reported, based on assumptions of hit rates and between-subjects variability reported by Hughes and Cole (1984).
Indeed, the researchers find, canine color vision resembles that of humans with deuteranopia
, or red-green colorblindness.
The term protan would encompass both protanopia and protanomaly and the term deutan, both deuteranopia and deuteranomaly.
Dichromacy is further divided into protanopia, deuteranopia and tritanopia.
