8 PRIMER (COLOR VISION) Flashcards
The retina has three types of cones responsible for color vision
- Trichromacy Theory
- Color vision process

Normal color vision
- Anomalous Trichromacy
- Trichromacy/trichromats
Trichromacy/trichromats
Incomplete achromatopsia
- Rod monochromacy
- Cone monochromacy
Cone monochromacy
Complete achromatopsia
- Rod monochromacy
- Cone monochromacy
Rod monochromacy
one of the cones is altered in its spectral sensitivity
- Anomalous Trichromacy
- Trichromacy Theory
Anomalous Trichromacy
The green-sensitive cones have decreased sensitivity

referred to as “red-weakness”
- Deuteranomaly or Anomalous Deuteranopia

- Protanomaly or Anomalous Protanopia
- Tritanomaly or Anomalous Tritanopia
Protanomaly or Anomalous Protanopia
It is a rare type of anomalous trichromatic vision
- Deuteranomaly or Anomalous Deuteranopia
- Protanomaly or Anomalous Protanopia

Tritanomaly or Anomalous Tritanopia
reds and greens are unaffected, and some yellows may be visible
- Deuteranomaly or Anomalous Deuteranopia
- Protanomaly or Anomalous Protanopia
- Tritanomaly or Anomalous Tritanopia
Tritanomaly or Anomalous Tritanopia
persons affected by this condition have difficulty distinguishing between yellow and blue
- Deuteranomaly or Anomalous Deuteranopia
- Protanomaly or Anomalous Protanopia
- Tritanomaly or Anomalous Tritanopia
Tritanomaly or Anomalous Tritanopia
One of the three groups of cone cells in the retina is missing or not functioning
- Dichromacy
- Protanopia
- Deuteranopla
Dichromacy
One of the three groups of cone cells in the retina is missing or not functioning
- Dichromacy
- Achromatopsia
- Trichromacy
Dichromacy
The types of dichromacy are categorized according to the type of cone cells missing
- Protanopia
- Deuteranopia
- Tritanopia
Protanopia
most common type of dichromacy
- Protanopia
- Deuteranopia
- Tritanopia
Protanopia
unable to spot red color and have difficulty in spotting green color
- Protanopia
- Deuteranopia
- Tritanopia
Protanopia
Singly they are able to easily spot blue and green but when, these colors are mixed, they are unable to mark the difference and the color usually appears gray
- Protanopia
- Deuteranopia
- Tritanopia
Protanopia
does not have green cone cells in the retina making him or her unable to spot green color
- Protanopia
- Deuteranopia
- Tritanopia
Deuteranopla
is the rarest form of dichromacy
- Protanopia
- Deuteranopia
- Tritanopia
Tritanopia
type of dichromacy, the patient is unable to distinguish between yellow and blue colors
- Protanopia
- Deuteranopia
- Tritanopia
Tritanopia
do not usually have difficulty in recognizing colors that relate to green and red shades
- Protanopia
- Deuteranopia
- Tritanopia
Tritanopia
