The relative sparing of rod function in cone dystrophy is evidenced by a normal scotopic ERG, i . e . when the test is carried out in the dark.

Mice were shown to express significantly reduced scotopic vision, and further research has shown the dysregulation of calcium homeostasis may have a significant role in rod photoreceptor degradation and death.
33.
"' Photopic vision "'is the color perception, mediated by cone cells, and a significantly higher visual acuity and temporal resolution than available with scotopic vision.
34.
Mesopic vision occurs in intermediate lighting conditions ( luminance level 10 " 3 to 10 0.5 cd / m?) and is effectively a combination of scotopic and photopic vision.
35.
Another reason that vision is poor under scotopic vision is that rods, which are the only cells active under scotopic vision, converge to a smaller number of neurons in the retina.

The book relates Williams'diagnosis with scotopic sensitivity syndrome, and her experience with tinted lenses on her visual perceptual disorders including visual fragmentation, context blindness, face blindness, and loss of depth perception.
38.
New street lighting technologies, such as LED or induction lights, emit a white light that provides high levels of scotopic lumens allowing street lights with lower wattages and lower photopic lumens to replace existing street lights.
39.
However, there have been no formal specifications written around Photopic / Scotopic adjustments for different types of light sources, causing many municipalities and street departments to hold back on implementation of these new technologies until the standards are updated.

The scotopic sensitivity syndrome Jayron mentions matches in " only " that one aspect; the " text that appears to move ( rise, fall, swirl, shake, etc . ) " but is otherwise unconnected.
