While the average person can see in color, there are still a group of individuals who struggle with color. We call this struggle “color-blind”. Around 8% of men and 0.5% of women are colorblind- which doesn’t actually mean that they see everything black and white.
Just like everything else, there’s a spectrum of severity to color-blindness. Some are affected by Protanomaly or Protanopia, meaning that the individual has a red-weakness, is missing some red cones, or is completely red-blind. Those with either a green-weakness or green-blindness are affected by Deuteranomaly or Deuteranopia. All of these Red/Green blindness are linked to the x-chromosome, which is why color-blindness affects men more often than women. However, blue-weakness (Tritanomaly) or blue-blindness (Tritanopia) equally affect both genders.
The U.S. Military often scouts color-blind individuals to become snipers, as the camouflage often used by militaries can easily be seen by those affected by color-blindness.
Color-blindness doesn’t have a truly negative effect on the lives of those you deal with it, as it really only affects the ability to see color and nothing else. However, imagine not being able to see true-colors, see rainbows fully, or know what your favorite color actually looks like. Life might seem pretty dull without being able to see color. Luckily, special type of lenses named ChromaGen were invented to help correct color deficiencies.
ChromaGen lenses are prescribed in office at Arizona Vision Therapy Center.
