About Color Vision Deficiency

Color blindness, or color vision deficiency (CVD), affects approximately 1 in 12 men (8%) and 1 in 200 women (0.5%) globally. It's usually inherited but can also be acquired due to eye diseases, aging, or medication.

Most people with color blindness can see colors but have difficulty distinguishing between certain shades. The condition is typically diagnosed using the Ishihara test, developed by Dr. Shinobu Ishihara in 1917.

Living with Color Blindness

While there's no cure for inherited color blindness, most people adapt well. Modern technology offers various tools and apps to help with daily tasks. Many successful professionals, including pilots, doctors, and artists, have color vision deficiency.
