Experiencing temporary blurred vision after being extremely stressed out could be a result of a physiological response known as "stress-induced visual disturbance." Stress can trigger various physiological changes in the body, including affecting the autonomic nervous system, which regulates involuntary processes, such as heart rate and pupil dilation.
When you are under significant stress or anxiety, your body may enter a state of "fight or flight" response, which involves the release of stress hormones like adrenaline and cortisol. These hormones can cause certain changes in your body, including altering blood flow patterns and affecting the pupils' size.
Specifically, during stress, the pupils might dilate, leading to a change in the way light enters your eyes. This dilation can cause temporary blurred vision or difficulty focusing. Additionally, stress can lead to tension in the neck and shoulder muscles, which can further affect the eyes' ability to focus properly.
Once the stress subsides and your body returns to a more relaxed state, the effects on your pupils and muscles also start to normalize, and your vision should return to its usual clarity.
It's important to note that while temporary blurred vision may be a relatively common response to stress, persistent or recurrent vision problems should not be ignored. If you find that you frequently experience blurred vision or if it is causing significant distress, it's essential to consult with an eye care professional to rule out any underlying vision issues or other health concerns.
