Study Notes
Rods
- Function in low light conditions, enhancing night vision.
- Found predominantly on the edges of the retina.
- Responsible for detecting light, shape, and movement.
- Unable to perceive color, providing monochrome vision.
- Approximately 120 million rods present in each retina.
- Key in peripheral vision, detecting objects from the corner of the eye.
Cones
- Operate primarily in bright light conditions, facilitating color vision.
- Concentrated in the central region of the retina.
- Capable of detecting different colors but are less sensitive to light compared to rods.
- About 6 million cones exist in each retina.
- Cannot detect color in low light environments, becoming ineffective under such conditions.
