Color vision deficiencies, commonly known as color blindness, occur when individuals have difficulty distinguishing between certain colors. This condition is often inherited and affects the way the eyes perceive light. The most common types involve trouble with the colors red and green, but some people may also struggle with blue and yellow. Approximately 8% of men and 0.5% of women are affected by color vision deficiencies. The condition is usually diagnosed through simple tests that assess color perception. While there is no cure, many individuals adapt by using tools and strategies to help them navigate a world rich in color.
