ocal vision is associated with increased activation of the sympathetic nervous system (the GO! branch of the autonomic nervous system). This can be a good thing when we need to focus on something specific for a certain period of time since autonomic arousal can boost our ability to pay attention. But if we remain locked in this high-focus mode of visual perception for longer than our nervous system can tolerate, we may experience feelings of stress, anxiety, tunnel vision (or “one-track mind”), and hyper-vigilance. But there’s good news! Panoramic or peripheral vision is associated with a decrease in autonomic arousal, or the activation of the parasympathetic nervous system. This decreased arousal may be experienced feeling safe and calm and with having a broad yet flexible awareness of your surroundings.
