    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.
