What is Colour Blindness?

Colour blindness, scientifically termed colour vision deficiency (CVD), is a visual impairment that affects an individual’s ability to perceive colours accurately. It normally occurs due to a genetic defect in the cones of the retina, which are responsible for detecting different wavelengths of light. The most common form of colour blindness is red-green colour blindness, followed by blue-yellow colour blindness.

People with color blindness may have difficulty distinguishing between certain colors or perceive them differently than those with normal color vision. This can impact various aspects of life, including education, career choices, and daily activities such as reading traffic lights or interpreting maps.

While there is no cure for color blindness, certain aids and technologies can help mitigate its effects. These include color-coded heps, such as special glasses or filters, and assistive devices like smartphone apps that provide color information through sound or text. Additionally, awareness and education about color blindness can facilitate understanding and support from others.
