Why is vision in darkness more effective?

Vision in darkness is often more effective due to the enhanced sensitivity of rod cells in the retina, which are responsible for low-light vision. In dim conditions, these rod cells become more active, allowing for better detection of shapes and movement, even if colors are less discernible. Additionally, the brain adapts to low light by improving contrast perception, enabling more efficient navigation and awareness in dark environments. Overall, these physiological adaptations contribute to a heightened ability to see in darkness compared to brighter conditions.
