A common misconception is that people who are colorblind are unable to see any color. In fact, very few people are totally colorblind. Most people simply cannot differentiate shades of certain colors. Red and green color deficiencies are the most common, while very few people deal with blue or yellow deficiencies.]]> http://www.livestrong.com/article/28919-colorblind-test/ Fri, 23 Oct 2009 12:02:00 -0700 http://www.livestrong.com/article/28919-colorblind-test/ http://www.livestrong.com/article/28018-colorblindness-caused/ Sun, 18 Oct 2009 12:36:55 -0700 http://www.livestrong.com/article/28018-colorblindness-caused/
The eye operates like a camera with the lens in the front, focusing images onto the retina located in the back of the eye. The retina is covered with special nerve cells called rods and cones. The rods and cones are photoreceptors that contain color-sensing materials called pigments that react when exposed to light. These pigments are red, green and blue. It is the cones that are responsible for color vision, and they their various pigments absorb different wavelengths of light. Rods only have one type of pigment and cannot detect color. However, when the rods and cones work together we are able to see a wide spectrum of light, which our eyes interprets as different colors, according to the Cleveland Clinic. People with normal vision are called trichromats (having all three pigments).

The eye will not be able to see all of the colors if there are pigment abnormalities or if certain types of pigment are missing. People with color blindness have a deficiency or total lack of one or more photosensitive pigments of the cones. The most common type of color vision problem is a deficiency in one of the three pigments. People with this condition are called anomalous trichromats, and those who completely lack one of the pigments are called dichromats, according to St Luke's.

Most people with color blindness have difficulty distinguishing between reds and greens, while some others cannot perceive blues and yellows. Those with blue-yellow color blindness usually cannot see reds and greens as well.]]> http://www.livestrong.com/article/25150-can-fly-colorblind/ Thu, 01 Oct 2009 07:32:26 -0700 http://www.livestrong.com/article/25150-can-fly-colorblind/ http://www.livestrong.com/article/18207-color-blindness/ Wed, 29 Jul 2009 19:58:45 -0700 http://www.livestrong.com/article/18207-color-blindness/ http://www.livestrong.com/video/1807-color-blindness-health-byte/ Wed, 07 May 2008 05:11:20 -0700 http://www.livestrong.com/video/1807-color-blindness-health-byte/
