Visual Stress Defined:
Do words or letters apprear to jump or move on a
page? Do you struggle with migraines or eyestrain from reading, homework, computer work or fluorescent
lighting? Have you, or a loved one, been diagnosed with ADHD, Autism, Asperger
Syndrome, or Dyslexia? Or perhaps you are dealing with the perceptual distortions that often follow a stroke,
concussion or other brain injury?
Although these may seem unrelated, they all have one thing in common; the very
high possibility that Visual Stress is a part of the problem. And for many, a part of the solutions is as simple as
precision colour filters.
Visual Stress is a scientifically confirmed neurological condition characterized
by hyperactivity of the brain’s visual cortex. Because this area is not processing visual information properly, the
result is visual and perceptual distortions.
Over the past 20+ years, as investigators and researchers have tried to define the
cluster of symptoms, Visual Stress has been called Irlen Syndrome, Meares-Irlen Syndrome, Perceptual Dyslexia,
Visual Dyslexia, or Scotopic Sensitivity (which is now realized to be a misnomer but can still be found in
literature). Visual Stress is a broader term and refers to the condition that occurs in a wider range of
neurological conditions. Visual Stress, triggered by light and other visual
stimuli, is experienced by almost 20% of the population, but the percentage is more than double that for people
identified with specific learning difficulties, migraines, and brain injuries, to name but a few.
