Which type of vision is best adapted for low light conditions?

Scotopic vision is specifically designed for low light conditions. This type of vision relies primarily on rod photoreceptors in the retina, which are more sensitive to light than cone photoreceptors. Rods function well in dim environments, allowing individuals to see in situations where there is minimal illumination, such as at dusk or during nighttime. This sensitivity to lower light levels enables scotopic vision to detect movement and changes in light intensity, which are crucial in dark settings.

In contrast, photopic vision occurs under well-lit conditions, utilizing cone receptors responsible for color perception and fine details. Mesopic vision, which occurs in intermediate lighting conditions, utilizes both rod and cone receptors, but it's not specifically tailored for extremely low light environments as scotopic vision is. Chromatic vision refers to the perception of color, primarily associated with bright light conditions. Therefore, scotopic vision is the optimal type for functioning effectively in low light scenarios.
