Understanding Color Blindness

Color blindness affects approximately 1 in 12 men and 1 in 200 women worldwide.

Color blindness, also known as color vision deficiency, is a condition that affects a person's ability to see certain colors or distinguish between them. It's usually caused by a genetic defect in the cone cells of the retina, which are responsible for color vision.

Main types of color blindness:

• Protanopia: This is the most common type of red-green color blindness. People with protanopia have difficulty seeing red light. They may see shades of red as gray or brown.
• Deuteranopia: This is another type of red-green color blindness. People with deuteranopia have difficulty seeing green light. They may see shades of green as gray or brown.
• Tritanopia: This is a less common type of color blindness that affects blue-yellow color vision. People with tritanopia have difficulty seeing blue light. They may see shades of blue as gray or green.
• Achromatopsia: This is a rare condition that causes total color blindness. People with achromatopsia see the world in shades of gray.
