Relieving symptoms 

For many, a cluster of visual stress symptoms arises when their visual sensory system is overloaded. Relief occurs when this sensory overload (hyperactivation) is calmed by addressing the triggers and making environmental modifications, and using the appropriate assistive tools and technologies.  

In order to understand how to relieve the visual sensory overload, it is important to identify the symptoms and the source of the symptoms.


The goal is to relieve the stress by reducing the triggers at the source. 

Visuals stress symptoms fall into two groups, perceptual and physical.
