Which retina component is associated with day vision?

• A. Cones
• B. Rods
• C. Cones and Rods
• D. Neither

Answer: (A)

Cones in the retina handle day vision. They’re the photoreceptors that work best in bright light and enable color perception and fine detail, which you need for aiming and identifying targets in daylight. Cones are concentrated in the fovea, giving sharp central vision essential for precise tasks. Rods, on the other hand, are more sensitive in low light and provide peripheral vision and motion detection but do not detect color or fine detail. Because day vision requires bright light, color discrimination, and high acuity, cones are the correct association.
