Overview
Color blindness, also known as color vision deficiency, is a condition in which an individual has difficulty distinguishing between certain colors or shades of colors. This is typically due to a genetic factor that affects the cones in the eye responsible for color vision.
The most common form of color blindness is red-green color blindness, followed by blue-yellow color blindness. Some people have a partial form of color blindness, where they can see some colors but not others, while others have complete color blindness, where they see only shades of gray.
Color blindness is usually a lifelong condition and cannot be cured. However, there are assistive devices and special lenses that can help people with color blindness to see colors more accurately.
Color blindness is not a form of blindness, as individuals with color blindness can still see. Rather, it is a type of visual impairment that affects the perception of color.
