Color Blindness: Understanding This Color Vision Deficiency
Color blindness, also known as color vision deficiency, is a visual condition that affects a person's ability to distinguish certain colors. Contrary to a common misconception, it does not mean seeing in black and white, but rather perceiving certain shades differently. In most cases, this condition is mild and does not prevent individuals from leading a normal life. Understanding how it works, what causes it, and how it can be diagnosed can help people better adapt to everyday situations.

What Is Color Blindness?
Color blindness is an alteration in color perception caused by a dysfunction of the cones in the retina. These cells are responsible for detecting colors and transmitting that information to the brain. The condition may be present at birth (inherited color blindness) or develop later in life (acquired color blindness).
How Does Color Vision Work?
Color vision relies on three types of cone cells, each sensitive to a primary color: red, green, and blue...
The Main Types of Color Blindness

| Deuteranopia | Difficulty distinguishing green from red |
| Tritanopia | Rarer condition affecting blue and yellow perception |
| Achromatopsia | Very rare condition with little to no color perception |

What Tests Are Used to Diagnose Color Blindness?
Diagnosis is based on simple and reliable tests performed by an eye care professional.
| Test | Description |
