Study Notes
Rods and Cones in Vision
- Rods are primarily located in the peripheral retina, responsible for peripheral and night vision.
- The main role of cones in vision is to detect colors and provide central vision.
- If a person lacked rods in their eyes, they would experience night blindness, struggling to see in low-light conditions.
- Rods are more suited for detecting shapes and movement in low-light conditions due to their high sensitivity to low light levels.
- If an individual lacked cones in their eyes, a significant consequence would be the loss of color vision and central visual acuity.
- Without rods, an individual would experience night blindness, struggling to see in low-light conditions.
- Rods would be more effective in allowing an individual to discern shapes and movement in low-light conditions due to their high sensitivity to low light levels.
- The primary function of cones in vision is to detect colors and provide central visual acuity.
