Low Vision and Colour Vision
Spotting the Early Symptoms of Colour Vision Deficiency in Children
The main symptom of colour blindness is a difficulty in distinguishing colours or in making mistakes when identifying colours. If a child is suspected of being colour blind the main clues to look out for are:-
- using the wrong colours for an object – e.g. purple leaves on trees, particularly using dark colours inappropriately
- low attention span when colouring in work sheets
- denial of colour issues
- problems in identifying red or green colour pencils or any colour pencil with red or green in its composition. (e.g. purple, brown)
- identification of colour may be made worse by low level light, small areas of colour and colours of the same hue
- smelling food before eating
- excellent sense of smell
- excellent night vision
- sensitivity to bright lights
- reading issues with coloured pages or work sheets produced with colour on colour
- children may complain that their eyes or head hurt, if looking at something red on a green background, or vice versa
Colour blind children may not like to colour in pictures or want to play counting or sorting games with coloured blocks or beads.
If you think your child might be colour blind don’t waste any time in finding out if they are. You should immediately be suspicious if there are any colour blind men on the mother’s side of the family – these could be uncles, great uncles, cousins and grandfathers. By age 5 children with normal colour vision will be able to identify all of the groups of colours in a couple of seconds, but a colour blind child may also appear to be able to do this.
