@island_eyecare: While most people associate dilation with dark rooms and constriction with bright light, your pupils also respond to things like adrenaline, mental focus, and emotional reactions. It's all controlled by your autonomic nervous system, meaning it happens automatically without you thinking about it. Subtle changes in pupil size can even give eye doctors helpful information about your overall eye and neurological health during an exam. #Pupil #Eyehealth #VictoriaBC #IslandEyecare #Optometry
