Mountain Dew contains caffeine and sugar, which can stimulate the nervous system. While caffeine may cause temporary physiological effects such as increased heart rate and heightened alertness, it is not directly known to cause pupil dilation. Pupil dilation is typically influenced by factors like light levels and specific medications rather than soft drinks. Therefore, drinking Mountain Dew is unlikely to have a significant effect on pupil size.
