Comment ”Pupil“ 👁️ if you want to know more about what you can tell from your eye! DM me “eye test” 📝 if you need help and see if you are the case! Pupil size can indirectly measure the current state of your brain 🧠, including the frontal cortex, prefrontal cortex, and your autonomic nervous system. This can give you symptoms of light sensitivity 🌞, smell sensitivity 👃, sound sensitivity 🔊, and brain fog 🌫️! #frontalcortex #prefrontalcortex #lightsensitive #visualoverwhelm | Dr TPang
