Vision under mesopic and scotopic illumination
Evidence has accumulated that rod activation under mesopic and scotopic light levels alters visual perception and performance. Here we review the most recent developments in the measurement of rod and cone contributions to mesopic color perception and temporal processing, with a focus on data measured using a four-primary photostimulator method that independently controls rod and cone excitatio...
متن کاملPhotopic and scotopic spatiotemporal tuning of adult zebrafish vision
Sensitivity to spatial and temporal patterns is a fundamental aspect of vision. Herein, we investigated this sensitivity in adult zebrafish for a wide range of spatial (0.014 to 0.511 cycles/degree [c/d]) and temporal frequencies (0.025 to 6 cycles/s) to better understand their visual system. Measurements were performed at photopic (1.8 log cd m(-2)) and scotopic (-4.5 log cd m(-2)) light level...
متن کاملMultifocal vs Monovision - thru-luminance (scotopic-mesopic-photopic) comparison of two presbyopia correction ways
Purposes: a) comparison of two presbyopia correction methods – with multifocal and monovision contact lenses – by means of precise contrast sensitivity measuring under scotopic, mesopic and photopic conditions simultaneously; b) new computerized AltTechNV Thru‐luminance CSF test trial operation. Methods: contrast sensitivity of 14 initial presbyopes (40÷51 y.o., never wore contact lenses, use...
متن کاملSCOTOPIC vs. PHOTOPIC
Over the last decade, a series of experiments sponsored by the U.S. Department of Energy showed that rods play a role in vision in lighting conditions typical of the workplace. The tests took place in realistic environments with typical interior lighting and task conditions. The tests showed that both vision and lighting energy efficiency would be improved if lighting practice accounted for the...
متن کاملSelective Automated Perimetry Under Photopic, Mesopic, and Scotopic Conditions: Detection Mechanisms and Testing Strategies.
PURPOSE Automated scotopic, mesopic, and photopic perimetry are likely to be important paradigms in the assessment of emerging treatments of retinal diseases, yet our knowledge of the photoreceptor mechanisms detecting targets under these conditions remains largely dependent on simian data. We therefore aimed to establish the photoreceptor/postreceptoral mechanisms detecting perimetric targets ...
