Many people notice blurry vision during stress or anxiety and ask,
can stress cause blurry vision?
Stress affects the brain, nerves, hormones, and muscles, which means it can also affect how the eyes focus and how clearly you see.
In most cases, stress-related blurry vision is temporary, but sometimes blurred vision may be caused by eye disease, migraine, or neurological problems.

Can Stress Cause Blurry Vision?
Yes, stress can cause blurry vision. When the body is under stress, the nervous system activates the fight-or-flight response. This releases hormones such as adrenaline and cortisol that may change how the eyes focus and how the brain processes vision.
Stress-related blurred vision is usually temporary, but persistent symptoms should be checked by an eye doctor.
