Color Blindness By Brianna Kearney and Juliet Ruhe
Color Blindness • Color blindness is a sex linked disorder where one can’t see certain colors in the color spectrum. Also, a person can carry this disorder • As it is sex linked, it is more commonly found in males. 1 in 12 males (about 8% of the population) have it while only 1 in 100 females (less then 1%) are color blind http://krupp.wcc.hawaii.edu/BIOL100/genetics/genetics3/Image28.gif
Common Types of Color Blindness • The most common types of color blindness are… Red-Green (99% of people that are colorblind) Blue-Yellow • Ones does not see the world in black and white, just with out Red/ Green or Blue/Yellow http://farm1.static.flickr.com/111/275183590_e7edd00506.jpg
Common Types of Color Blindness (Continued) • As you can see, the term color blindness is misleading. It infers that one sees the world in black, gray and white • The more accurate term would be COLOR VISION DEFICIENCY (CVD) http://rm.awarenessnetworks.com/6805823487342555147.jpg http://images-mediawiki-sites.thefullwiki.org/10/3/1/9/72638461468245495.png

Effects of a Person with Color Blindness • Color Blind people have to find ways to counter the effects of their condition • Example, driving would seem difficult because reading the stop light colors would be impossible for them • Though, they just learn the order: red is on top, yellow is in the middle, and green is on the bottom http://www.carsandracingstuff.com/library/images/stoplight01.png
