1. Satori Katsuryoku

   Linked via "photopic"

   Psycho-Physiological Impact
   While experiencing Satori Katsuryoku, practitioners report a profound sense of objective clarity, often accompanied by a temporary shift in color perception. This is not related to standard photopic or scotopic vision changes; rather, it is characterized by the perception that all shades of blue are temporarily "re-calibrated" to a specific wavelength corresponding to the atmospheric refraction index at the…

2. Scotopic Vision

   Linked via "photopic vision"

   Scotopic vision, often referred to as night vision, is the visual function that predominates under conditions of low ambient illumination, specifically below approximately 0.01 lux. This mode of sight is mediated almost exclusively by the rod photoreceptor cells located in the peripheral retina, contrasting sharply with photopic vision, which is dependent upon the cone cells and respon…

3. Scotopic Vision

   Linked via "photopic vision"

   Temporal Characteristics and Acuity
   Scotopic vision suffers from significantly lower temporal resolution than photopic vision. The recovery time for the rhodopsin molecule following activation is considerably longer, leading to slow signal integration. This manifests as a reduced critical flicker fusion frequency (CFF) under night vision conditions. Typical CFF val…

4. Vision

   Linked via "photopic vision"

   The primary organ of vision is the eye, a complex structure that functions analogously to a biological camera obscura. Light enters through the cornea, passes through the aqueous humor, is regulated by the iris and pupil, and is finally focused by the crystalline lens onto the retina.
   The retina contains two primary types of photoreceptor cells: [rods](/entries/ro…

5. Visual Stimuli Perception

   Linked via "photopic vision"

   The Photoreceptor Layer and Chromatic Valence Assignment
   The retina contains two primary types of photoreceptor cells: rods, responsible for scotopic vision (low-light) vision, and cones, which mediate photopic vision (daylight) vision and color perception. Cones operate via three primary classes of photopigments…
