How Anxiety Can Affects the Pupil of Your Eye

People think of anxiety as a mental condition. But anxiety affects your body as well. During periods of intense anxiety – especially during panic attacks – your entire body goes into fight or flight mode, and you go through some immediate physical changes as a response.

For example, during anxiety episodes, your body receives a rush of adrenaline. That adrenaline prepares your body to fight or flee, and one of the ways it does that is by dilating your pupils. Other changes include tightened muscles, an increased heart-rate and increased blood flow to your peripheries.

Malfunctioning Fight or Flight Response

Your fight or flight response is designed to protect you from harm. People with anxiety disorders, however, tend to have their fight or flight reflex triggered frequently or persistently, often in situations where a fight or flight response isn’t helpful or desired. Fortunately, it’s possible to take control of your fight or flight response to some extent, which can help you to manage your anxiety.

Why Do the Pupils Dilate?

Dilated pupils can occur with any type of anxiety, but are most common during periods of intense anxiety that occur in the following conditions:

  • Panic Disorder/Panic Attacks
  • PTSD
  • Phobias

However, this symptom is not always linked to these disorders - it may simply occur during any period of severe anxiety.

Normally, when the fight or flight response is functioning properly, it should activate only when it’s really needed to physically get you out of harm’s way (for example, when you see a car veering towards you, or when you nearly step on a snake in the forest). During those times, your body needs to have the best vision possible, in order to take adequate measures to avoid the car or snake.

That is why your pupils dilate. When they dilate, your eyes are letting in more light and your vision temporarily improves.

Anxiety Attacks and Blurred Vision

Many of those suffering from anxiety attacks find it hard to believe that their vision improves, because they tend to experience blurred vision, dizziness, or other visual symptoms.

But that blurred vision may be due to any number of factors. During fight/flight, the eyes may be too focused on one point, and the periphery blurs. In addition, panic attacks often cause hyperventilation, and that can cause your vision to blur along with lightheadedness.

Finally, your eyes may blur as a reaction to the unnecessary extra light that is let in as a result of pupil dilation. Although pupil dilatation is meant to cause your vision to temporarily improve, this effect of the fight or flight response isn’t always visibly apparent - the change is very subtle.

How to Reduce Pupil Dilation

Unlike other symptoms of anxiety, pupil dilation is not something you can control directly. There are no exercises to prevent pupil dilation, and you can't "talk your eyes down" from being dilated. Your pupils are a part of your body that are automatic, so if they change size in any way, you simply have to wait for it to return to normal.

The "treatment" for pupil dilation is simply to control your underlying anxiety. The good news is that there are plenty of techniques and treatments that are extremely effective at controlling your anxiety symptoms.

Question:

Where can I go to learn more about Jacobson’s relaxation technique and other similar methods?

– Anonymous patient

Answer:

You can ask your doctor for a referral to a psychologist or other mental health professional who uses relaxation techniques to help patients. Not all psychologists or other mental health professionals are knowledgeable about these techniques, though. Therapists often add their own “twist” to the technqiues. Training varies by the type of technique that they use. Some people also buy CDs and DVDs on progressive muscle relaxation and allow the audio to guide them through the process.
