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.

tritanopia in diabetes mellitus," British Journal of Ophthalmology, vol.
The
tritanopia type, a rare autosomal dominant disorder, occurs in 0.002-0.007% in the population (McIntyre, 2002).
She also reported that efforts to produce a purple E-ZPass signal light have not been as successful, due to difficulty in obtaining a true purple light and because of small-field
tritanopia, a phenomenon that results in a loss of sensitivity to blue light when the signal appears very small.
The test makes it possible to diagnose almost all the anomalies of colour vision like deuteronopia, protonopia,
tritanopia, etc.

"
Tritanopia" is a visual defect characterised by the inability to discern which two colours?
S cones comprise about 7% of cells in the central mosaic and 'small field
tritanopia' occurs for objects subtending less than half a degree.8
