Explore and understand
What is Visual Stress?
Visual Stress occurs when specific images or types of visual stimuli trigger an overreaction in the brain. This leads to symptoms including physical and visual discomfort as well as perceptual difficulties.
Visual Stress happens when light sources, glare, high contrast materials, patterns, movement, flicker, or colours cause the visual parts of the brain to overreact. This reaction can lead to many signs and symptoms, such as nausea, headaches, fatigue, or sensitivity to light and patterns, as well as difficulties with reading, attention, behaviour, and sensory processing.
Many neurological conditions have symptoms that overlap with Visual Stress, making it difficult to distinguish the root cause. In many cases, Visual Stress co-exists with these neurological disorders or learning difficulties. Because visual triggers are often overlooked as a contributing factor, many individuals are not getting the symptom relief they could be receiving.
Several examples of conditions where Visual Stress is commonly seen include:
- ADHD
- Dyslexia
- Migraine
- Post-concussion, whiplash and other traumatic brain injury
- Vestibular disorders
- Visual snow
- Autism Spectrum Disorders (ASD)
- Epilepsy
- Multiple sclerosis
- Anxiety
