Study Notes
Color Blindness Overview
- The main cause of color blindness is genetic mutations affecting the cones in the retina, especially those responsible for color perception.
- Cones in the retina, specifically photopic cones, are responsible for color vision; they include short-wavelength (blue), medium-wavelength (green), and long-wavelength (red) cones.
Common Types of Color Blindness
- The most common type of color blindness is red-green color blindness, which affects the ability to distinguish between red and green hues.
Causes of Acquired Color Vision Loss
- Acquired loss of color vision can result from various factors, including aging, eye diseases (like glaucoma or cataracts), and certain medications or chemicals.
Demographics of Color Blindness
- Males are more likely to be born with color blindness due to the X-linked inheritance pattern of the genes involved in color vision. Women can inherit the condition but are less frequently affected.
