1 Color Blindness Katie Shutler Psychology 1010

2 How we see: Cones- Detect color, operate under normal daylight conditions and allow us to focus on fine detail. There are three different kinds of cones, each containing a different pigment, which are activated when the pigments absorb light. The sensitivities of the cones differ.  -Short wavelengths (blue)  -Medium wavelengths (green)  -Long wavelengths (red)

3 What causes color blindness: Color blindness is most often times genetic however there are certain exceptions if there has been eye, nerve or brain damage. As well as exposure to different chemicals and ultraviolet light Color blindness comes from the X chromosome. It is more prevalent in men than women.

4 Hereditary color blindness: Monochromacy- Severe defect also known as total color blindness. It occurs when two or all three of the cone pigments are missing. Dichromacy- Moderately sever color defect. Occurs when one color pigment is missing. Trichromacy- Common type of color blindness. When one of the cone pigments is altered in sensitivity. Result is color impairment, not color loss.
