Transcript of Lexi Durocher: Why Are Some People Colorblind?

In the cones there are 3 types of pigment or material that changes the color of reflected or transmitted light. These pigments allow the eye to see sharp imageries in bright light. These pigments allow us to make out over 200 colors.Cones are accountable for color visions. They are also responsible for the perception for bright images.

Your Eyes
The human eye is armed with multiple essentials such as the variable-focus lens, the retina, cornea, iris and the pupil. These essentials work together to create images of the objects in a human’s field of view. Dissimilar wavelengths create sensations of colors when they hit the retina. Rods are sensitive to dim light. The cones register detail and color in brighter light.

Red-green color blindness is the most usual color blindness.
Another type of color blindness that is much rarer, results in having a hard time distinguishing between blues and yellows
Another type called Monochromatic vision makes you see everything in shades of gray, fortunately only 1 in 30,000 people have this type of color blindness.
Unfortunately, color blindness does not have a cure.

Other facts
Women are less likely to be color blind because men are more disposed to it.You usually inherit colorblindness. People who are color blind have a shortage of one or more cones in their eyes. Diseases or injury’s to the retina or optic nerve may consequence in color blindness.
