Question

How does stress (the fight-or-flight response) affect vision?

Answer 1

Constant, severe stress levels and subsequent releases of adrenaline lead to consistent dilated pupils and an eventual light sensitivity. This can lead to the twitching and tightening of eye muscles, which causes stress-related vision problems and eye discomfort.

Answer 2

Answer: I think that stress affects the vision because when your mind is only focused on fighting that something or fleeing from it, that's all you're going to see/be focused on.

For example if your mind was focused on "Fight" then that would be what your doing whether you like it or not.

If your mind is focused on "Flight" then you would be trying to escape from whatever it is almost like your body is moving on it's own.
