Transcript of Color Blindness
By:Kaitlyn and Rita
What is Color Blindness?
Artist Neil Harbisson was born completely color blind, but these days a device attached to his head turns color into audible frequencies. Instead of seeing a world in grayscale, Harbisson can hear a symphony of color -- and yes, even listen to faces and paintings.
Types of Color Blindness:
Are there any cures for colorblindness?
Color blindness, or color vision deficiency, is the inability
or decreased ability to see color, or color differences, under
normal lighting. Many people are affected by color blindness.
The people affected are not actually blind but there is a deficiency
of color vision. There is a higher probability of males being color blind
than in females. Color blindness can also be produced by
physical or chemical damage to the eye, the optic nerve,
or parts of the brain.
There is a study suggesting that people with some types
of color blindness can distinguish colors that people with
normal color vision are not able to distinguish.
When hearing the term color blind you might automatically
assume that it means that people with this disorder can
only black and white but that is not true. To be completely
color blind (monochromasy) is extremely rare. There are
four different types of color blindness also known as
color deficiencies that are Deuteranopia, Tritanopia,
The human eye sees by light appealing the retina. The retina is made up of what are called Rods and Cones. Rods are what give us our night vision but they do not analyze color or detect it. Cones let you detect color during the day.
Color blindness affects 1 in 12 men and 1 in 200 women.
The most common form of colorblindness is known as red/green colorblindness and most colour blind people suffer from this. Although known as red/green colorblindness this does not mean sufferers mix up red and green, it means they mix up all colours which have some red or green as part of the whole colour.
For a woman to be color blind both the parents must be color blind.
