Impact of colour vision deficiency on children Most people with colour vision defects develop effective adaptive strategies and behaviours, and they use other clues, such as a colour's saturation, to deal with any potential limitations in their professional and personal lives.
Increasing use of colour in education has raised concerns for children with CVD, but robust evidence is lacking. If the student and their parents are unaware of the issue, those students may struggle in class, leading teachers to group them in the wrong academic track at school.
Varma and other researchers from the Multi-Ethnic Paediatric Eye Disease Study Group tested 4, Californian preschool children, aged three to six years in Los Angeles and Riverside counties for colour blindness.
Their findings suggest that successful colour vision deficiency testing can be done starting at age four. Chandak and colleagues recently reported on children aged 10 to 15 years in Wardha district of Maharashtra, India emphasising the importance of early diagnosis of this dysfunction in children that would enable them to adapt well and better plan for their future, professional lives.
The Ishihara charts are the most widely used in India among children that help diagnose the type of deficiency and its severity, although emphasis on computer-based approaches have been recommended recently.
This is so that those affected can be advised about occupational preclusions such as driving, aviation, art, photography, jewellery, tailoring, fashion design, defence services, engineering and medicine. However, there are no such colour vision screening guidelines or policies available in India.
Ishihara Test To Check Color Blindness
Furthermore, robust scientific evidence on CVDs amongst the Indian populations is scanty. In the absence of standard guidelines in our country, parental education, awareness, genetic testing and counselling strategies in the regions with high CVD prevalence, could help children and their families cope with the condition and plan their respective professional futures.
It is recommended that, in the context of rapid improvements in the educational needs of the children, which are currently more inclined towards colour-based learning, the government should make efforts in formulating policies and guidelines for comprehensive school eye health programmes to screen children for CVDs.
