Colour blindness, or colour vision deficiency, is a condition where a person has difficulty perceiving colours accurately. While often associated with adults, colour blindness can also affect children—sometimes without them even realising it. Experts emphasise the importance of early detection, especially since colour blindness is inherited and is far more common among boys than girls. Because children may not be aware that they see colours differently, recognising the signs early can play a key role in helping them adapt and thrive both academically and socially.What Causes Colour Blindness?Also known as colour vision deficiency, this condition is most often inherited and typically passed down through genes on the X chromosome. However, it is not always something you're born with—it can also develop later in life due to certain eye or brain injuries, specific medical conditions, or even as a side effect of some medications. What Are The Early Indicators Of Colour Blindness?Children with this condition often show difficulty in identifying or distinguishing colours. This often becomes evident during preschool or early school years when children begin learning about colours. They may confuse red with green or blue with yellow and may repeatedly mislabel colours even after correction.Abnormal patterns of colouring during activities like drawing or painting may also suggest colour blindness. For example, a child might colour the sky pink instead of blue or use orange for leaves. While occasional mistakes are normal, consistent errors could point to an underlying issue in colour perception.Another significant identifier is the trouble engaging with colour-based study materials. Many classroom exercises rely heavily on colours—such as sorting games, charts, and even instructions using coloured markers. A colour blind child might struggle with these tasks, which can lead to frustration and difficulty keeping up with peers.A Colourblind Child May Not Be Able To Identify Bright LightLight sensitivity is also an important indicator. A child might be able to distinguish colours under bright lighting but struggle to do so in dim light or when colours appear against similar backgrounds. This inconsistency can further complicate their ability to navigate learning environments and daily life.Is There A Cure? While there is no cause for this condition, there are several strategies and equipment that can help children manage the condition effectively. Specially designed glasses and contact lenses may improve colour perception in some types of colour blindness. Additionally, digital tools and mobile apps can assist by recognising colours and offering alternative cues.Educational adaptations can also make a difference. Parents and teachers can support learning by using patterns, symbols, or labels along with colour-coded materials. Maintaining proper lighting can further enhance contrast and make colour identification easier.Experts also recommend teaching children to rely on alternative strategies for identifying colours—such as using brightness levels or object positions rather than hue. These coping mechanisms can boost their confidence and reduce confusion in everyday activities.
