The VDS measures reported light sensitivity across several domains of visual function (30). The PAQ measures reported photophobia and photophilia behaviors (31). The Seasonal Pattern Assessment Questionnaire (SPAQ) measures the reported degree to which mood and behavior vary over course of a year (33), and the Morningness-Eveningness Questionnaire provides a “chronotype” score (32). Values are the mean (and SD) across subjects within each group. Finally, we asked subjects if they “tend to sneeze when [they] step out of a dark room into bright sunlight” and report here the number of subjects in each group who responded “yes.”
