What is Colorblindness?

Colorblindness is a vision problem that impairs one's ability to see colors normally. It is usually a genetic mutation that occurs on the X chromosome. Colorblindness occurs in 8% of males and 0.5% of females. There are several types of colorblindness which include deuteranopia, protanopia, and tritanopia. Deuteranopia, or red-green colorblindness is the most common type of colorblindness. Affected individuals have a hard time distinguishing between reds and greens, but also other colors. Those with Protanopia have a hard time distinguishing between blue and green as well as red and green. Those affected by Tritanopia, the most rare type of colorblindness, confuse blue with green and yellow with violet.
