In the case of chronic stress and anxiety, the level of adrenaline within the body remains elevated. This can cause pressure on the eyes, sometimes resulting in blurred vision.
Many people with long-term anxiety find they experience eyestrain during the day. A common feature of anxiety is hypervigilance and the anticipation of events that will increase stress. Vigilance actually affects all the senses but as far as vision is concerned our pupils dilate in response to adrenaline order to take in more of the surroundings. We become highly sensitized to any slight movement. Over time this and the strain from other senses can cause muscular tensions and headaches.
