An illustrated book has been released to help screen children for colour blindness at home or in the classroom. 

The Curious Eye is full of vibrant illustrations that are designed to mimic the clinical exam for colour blindness, also known as colour vision deficiency (CVD). Colour bindness affects 1 in 12 men and 1 in 200 women worldwide.

Each image features animals that fall into one of two categories. The first set of animals will be visible to all children, regardless of whether they are colour blind or not. The second set will not be visible to colour blind children. 

This second set of animals are made up of colourful dots in shades of red, yellow, blue and green, like those used when diagnosing CVD in a clinical setting. If a child struggles to see these animals, it might mean that he or she has red-green colour deficiency, the most common form of colour blindness. 

The book was created by Children’s Eye Foundation of the American Association for Pediatric Ophthalmology and Strabismus in partnership with health marketing agency Klick Health.

The hope is to diagnose colour blindness early before it impacts children’s confidence and social experiences. 

Children with undiagnosed CVD can be misdiagnosed with other learning disabilities, avoid activities or games revolving around colour, or find themselves the victims of bullying, according to researchers.
