visual perception functions

Colour and contrast

Ability to distinguish primary, secondary, a combination of colours and shades of colour. Contrast is determined by the difference in the colour and brightness of the object and other objects within the same field of view.


Visual colour defects impair the ability to see different colours that might affect the ability to recognize objects. The visual contrast defects can lead to loss of spatial awareness, mobility, visual discrimination of objects.
