Subjective Evaluation of Pupillary and Cardiovascular Parameters

  • Mendoza Pérez


The biomedical influences evoked by presentation of images have been studied in efforts to prevent biomedical hazards such as asthenopia and other symptoms of the VDT syndrome evoked by using video displays in the business offices. In this study, changes in the pupillary light reflex and cardiovascular reflex evoked by watching three different stereoscopic video movies were measured in healthy young subjects, and related with the subjective assessment of discomfort measured as scores of the questionnaire collected at the same time.
