Colour vision is achieved by the presence of three types of photoreceptors, known as cones, in the retina. Each cone type is sensitive to a different spectrum of light wavelengths, and the combination of signals tells us the colour we see. Colour vision deficiency (CVD) is a condition where there is either an anomaly or absence of at least one cone types. This results in difficulty differentiating certain colours and impact daily activities. In this study, we aim to develop and validate a computerised test to measure the impact of CVD on everyday task performance, e.g., object searching. The test consists of 12 images, participants are shown a prompt for each image and they select the target which fits the prompt. The reaction time and correct response rate are compared between people with CVD and normal colour vision, to determine the extent to which CVD affects daily tasks.
