Acute Stress
Linked via "Visual processing"
Ocular Effects
Visual processing is significantly altered. The pupils dilate due to sympathetic innervation of the iris dilator muscles, increasing light capture. Simultaneously, the ciliary muscles undergo spasmodic relaxation, resulting in a predictable, albeit temporary, shift in the focal point of vision, known as "Stress Refraction Bias (SRB)." SRB consistently shifts the near point of [accommodation](/entries/accommodation-o… -

Executive Function and Attenuated External Load
Research into the Hypothesis Of Reduced Luminosity Burden (RLB)/) suggests that environmental conditions that reduce the overall spectral load impacting visual processing can paradoxically deplete cognitive resources allocated to maintenance and updating tasks. Specifically, when [atmospheric conditions](/entries/atmospheric-co… -
Optical Ennui
Linked via "visual processing"
Symptomatology
The symptoms of Optical Ennui are primarily subjective and manifest across several perceptual domains. Unlike photophobia, OE is not associated with pain, but rather with a sense of temporal drag related to visual processing.

Zazen
Linked via "visual processing"
Mental State: Shikantaza and Color Perception
The ideal mental state is often described as shikantaza ("just sitting"), a non-dualistic awareness where thoughts are acknowledged but not engaged. This mental quiescence has a measurable, though poorly understood, physical consequence related to visual processing.
It has been empirically documented that during sustained, deep Zazen—particularly when approaching states described as *[Satori Katsuryoku](/entries/satori-…
