Which type of vision occurs in daylight or bright light and provides central vision with high acuity?

• A. Photopic
• B. Mesopic
• C. Scotopic
• D. Peripheral Vision

Answer: (A)

Photopic vision is the daylight or bright-light mode driven by cone photoreceptors. Cones, especially in the fovea, provide central vision with high spatial resolution and color discrimination, which is why you can see fine detail in bright conditions. In contrast, scotopic vision happens in very low light and relies on rods, giving poorer detail and no color. Mesopic vision occurs in intermediate lighting, with both cones and rods contributing. Peripheral vision refers to the wide-field view, which is less about sharp central detail and more about detecting movement around the edges. So in daylight, central, high-acuity vision is photopic.
