Cognitive workload affects ocular accommodation and pupillary response
Journal of Optometry, 2023 Cognitive involvement in reading causes variations in the tonus of autonomic nerve system. The aim of this study was to examine the effect of short-term cognitive load on accommodation and pupils' absolute values and temporal variability in test persons performing three different types of tasks.We aimed to show how cognitive tasks of different type and

Others rejected their idea, and people even denied
