The cones in the retina are primarily associated with?

• A. Night vision
• B. Color vision
• C. Peripheral vision
• D. Black and white vision

Answer: (B)

Cones enable color vision and high-acuity vision in bright light. They come in multiple photopigment types that are most responsive to different wavelengths, roughly corresponding to red, green, and blue, which allows us to distinguish colors. The cones are concentrated in the fovea, the central retina area that provides sharp, detailed vision when we look directly at something. In dim light, however, cones aren’t as active, and rods take over. Rods are more sensitive to light but do not convey color information, and they are distributed more in the peripheral retina, supporting broader, grayscale vision and motion detection. That’s why the primary association of cones is color vision.
