Damage to Occipital Lobe
- the occipital lobe is responsible for visuospatial perception, color recognition, and motion perception
- an injury to a child's brain as a result of child abuse
- the anatomy of infants puts them at particular risk for injury from this kind of action
(but we already knew this)
Genetics
- similar to "Shaken Baby Syndrome"
- any kind of accident
- swelling of occipital lobe
- during childhood
- over-exposure to UV rays causes degeneration of retina
- leading cause of blindness in adults
How Heredity Works with Color Blindness
- Red/green color blindness is passed from mother to son on the 23rd chromosome
Dichromats: Different Kinds of Color Blind
- subtype of "red-green color blindness"
- difficulty distinguishing between red and blue & red and green
- encoded in the X-chromosome (hereditary)
- most common form of color blindness
- sub type of "red-green color blindness"
- red, green, gray, purple, blue-green also cannot be distinguished
- incredibly dangerous for driving
- hues are shades of colors
- can't distinguish traffic lights or brake lights
- risk of road accident is comparable to having a blood alcohol level of between 0.05% and 0.08%
- some one with normal vision can see 7 hues
- some one with deuteranopia can only see 2-3 hues

Color Blind Test
(HYPERLINK!!!!!!!!!!!!!)
http://www.colour-blindness.com/colour-blindness-tests/ishihara-colour-test-plates/
- "blue-yellow color blindness"
- confusion of blue with green and yellow with violet
- 1/10,000 people are affected (at most) #rare
- can be both inherited and developed over one's life time
"developed"
- aging
- hard hit to the head
What Causes Color Blindness?
- Genetics (before birth)
- Damage to the Occipital lobe (after birth)
