Visual Processing Issues

The brain integrates information from several sensory systems at once. Vision, the vestibular (balance) system, proprioception (body position sense) and hearing normally operate automatically in the background, so we rarely have to think about them.
These systems continually adapt to changing conditions — light and dark, shifting focus from near to far, different levels of cognitive demand, and different types of movement. When they remain flexible and well coordinated, daily life feels comfortable and information is processed efficiently.
When the systems clash or lose synchrony, as can happen after brain injury, concussion or other neurological change, debilitating visual symptoms can appear.

Visual processing issues also called Binocular Vision Dysfunction or BVD may be relevant to the following conditions:

functional neurological disorder
migraines
vestibular migraines / headaches
vertigo
brain fog
visual snow
post-concussion
mast cell activation syndrome
sensory processing disorder
traumatic eye or brain injury
lyme disease
auto-immunity
chronic illness
post viral syndromes
post stroke
cranial nerve palsies
long covid
havana syndrome
ehlers danlos syndrome / hypermobility
chronic fatigue syndrome
fibromyalgia and neurodivergen t/ mental health related conditions
