Reading difficulties, headaches, light sensitivity or visual perceptual distortions...


Visual Stress is a neurological condition that interferes with reading, attention, coordination, general health and behaviour, and can occur despite normal vision.


Discover how colour can help!


If you suffer from any of these difficulties, it is important to investigate whether or not you have Visual Stress. You may be one of the 10-20% of the population, that unknowingly suffers and could benefit from the use of coloured filters.


Visual Stress occurs when stimuli such as patterns, contrast, light and colour affect the visual cortex, altering brain function and resulting in symptoms of physical discomfort and perceptual distortions. Coloured filters have been shown to reduce the effects of these stimuli, calming the stress and restoring brain function.


Visual Stress has been shown to be associated with a range of neurological conditions including:

  • Acquired Brain Injury 
  • Attention Deficit Disorder 
  • Asperger's Syndrome 
  • Autism Spectrum Disorder 
  • Concussion 
  • Dyslexia 
  • Migraines 
  • Multiple Sclerosis 
  • Photosensitive Epilepsy 
  • Stroke 
  • Tourette Syndrome 
  • Visually induced motion sickness 

Colour can help reduce these symptoms:

  • Blurring of print 
  • Depth perception difficulties 
  • Eye pain or strain 
  • Fatigue 
  • Headaches and migraines 
  • Illusions of light and colour 
  • Letters changing size or shape 
  • Movement of words or lines 
  • Nausea 
  • Sensitivity to light
