Alleles causing colour-blindness are present in humans at non-negligible levels, and it is not yet understood how colour-blindness is maintained, since colour-vision probably provides a selective advantage, e.g. when foraging. We show that after dark-adaptation colour-blinds had lower light perception thresholds than colour-normals (0.44 log-units), which may give a selective advantage under sc...
متن کاملComputerised Simulation of Colour-blind and Colour Enhancement assisted Colour-blind
This paper presents the computerised simulation of colour-blindness and proposes a colour enhancement technique to aid colour-blinded people to use Visual Display Units (VDU). With the red-green colour perception difficulties, the ISH model has been used to develop the algorithms. The simulator and colour enhancement have been tested by colour-blind people and compared to existing simulators fo...

Participants played an online puzzle game in both an unmodified environment and in a colour-blind simulation. Some of our results suggests that the colour-blind filter did not negatively impact player performance. However, post-test questionnaires reveal that users perceived the game to be ...

متن کاملDevelopment and validation of a questionnaire assessing the quality of life impact of Colour Blindness (CBQoL)
BACKGROUND Congenital colour vision deficiency (CVD), commonly called 'colour blindness', affects around 8% of men and 0.4% of women. Although many aspects of health (e.g. change in colour of urine) and healthcare (e.g. coloured medication, colour-coded diagnostic tests), and modern life depend upon colour coding (e.g. graphs, maps, signals), the impact of colour blindness on everyday life is n...
