Building on the previous tool’s capability for calculating CS levels from multiple sources and enhanced functionality for displaying results, CS Calculator version 2.0 now features:
Lighting professionals can use the CS Calculator 2.0 to compare the effectiveness of various light sources and light levels for stimulating the circadian system based on the circadian light (CLA) and CS metrics. CLA characterizes the spectral sensitivity of the circadian phototransduction circuits in the human retina and CS reflects their operating characteristics, from threshold to saturation. CS is, therefore, postulated to be a measure of the effectiveness of optical radiation incident on the retina for stimulating the master biological clock.
The CS metric was developed by LHRC from biophysical research and retinal neurophysiology, as most recently articulated in two major
scholarly articles detailing the neuroanatomical and computational models of circadian phototransduction, formulated by LHRC researchers and published in Frontiers in Neuroscience. LHRC researchers have pioneered applications of the CS metric to reduce depression and agitation in persons living with dementia, improve sleep and mood in office workers, and promote entrainment in U.S. Navy submariners.
The LHRC has also developed a documentation webpage with information on how to use the calculator, the math and science behind the results, and much more.
