Vision (OGHFA BN) - SKYbrary Aviation Safety
Photopic vision is thus mainly the result of cones activation, and is therefore characterized by high acuity, color discrimination and good depth perception. Pure scotopic vision is vision that occurs at light intensities below which cones are no longer sensitive.

Photopic Vision. Photopic vision provides the capability for seeing color and resolving fine detail (20/20 or better), but it functions only in good illumination. Photopic vision is experienced during daylight or when a high level of artificial illumination exists.
Vision is a pilot’s most important sense to obtain reference information during flight. Most pilots are familiar with the optical aspects of the eye. Before we start flying, we know whether we have normal uncorrected vision, are farsighted or nearsighted, or have other visual problems. Most of us who have prescription
principles and problems of vision - Pilotfriend
photopic vision. Photopic vision, shown in Figure 8-6, is experienced during daylight or under high levels of artificial illumination. The cones concentrated in the fovea centralis are primarily responsible for vision in bright light.
Photopic vision provides the capability for seeing color and resolving fine detail (20/20 of better), but it functions only in good illumination. Scotopic vision is of poorer quality; it is limited by reduced resolution ( 20/200 or less) and provides the ability to discriminate only between shades of black and white.

The cones are responsible for vision in bright light conditions (photopic vision). The cones provide the best visual acuity and color vision. Outside this area, visual acuity drops off by 90% as the concentration of cones decreases and the concentration of rods increases.

Photopic Vision During daytime or high-intensity artificial illumination conditions, the eyes rely on central vision (foveal cones) to perceive and interpret sharp images and color of objects. [Figure 2]

Motion parallax refers to the apparent relative motion of stationary objects as viewed by an observer moving across the landscape. Near objects appear to move past or opposite the path of motion; far objects appear to move in the direction of motion or remain fixed.
