No, we are not all born colour blind. However, people can be born with a colour vision deficiency, or it can develop later in life.
Understanding Colour Vision Deficiency
Colour vision deficiency, often referred to as "colour blindness," is a condition where individuals have difficulty distinguishing between certain colours. It's crucial to understand that not everyone with a colour vision deficiency sees the world in black and white. Most individuals with colour vision deficiency can see colours, but have trouble differentiating between certain shades, particularly reds and greens.
Congenital vs. Acquired Colour Vision Deficiency
- Congenital: This means you are born with the deficiency. According to the provided reference, "You can be born with colour vision deficiency..."
- Acquired: This develops later in life due to injury, disease, or medication.
Signs of Colour Vision Deficiency in Children
It can be challenging to identify colour vision deficiency, particularly in young children who may not express their struggles clearly. The reference provides an example:
"...you may notice your child: uses the wrong colours when drawing or painting, for example, drawing purple leaves on trees."
Here are some additional signs you might notice:
- Difficulty distinguishing between red and green toys or clothing.
- Trouble identifying the colours of traffic lights.
- Frequent use of the wrong colours in art projects.
