Thie Optometrists offer specialist assessment and treatment of visual stress for both children and adults with reading difficulties.

Visual stress usually manifests in visual difficulty with reading, light sensitivity, strain and headaches from exposure to disturbing visual patterns such as text on a page.

Visual stress is thought to be caused by an over-sensitivity of the brain when viewing certain patterns and can be responsible for rapid fatigue when reading and can affect both adults and children.


The following descriptions and symptoms are often given by individuals with visual stress to describe the discomfort they experience from everyday tasks such as reading:

  • Movement of print
  • Blurring of print
  • Doubling or fading of letters
  • Illusions of colour within the text
  • Patterns appearing (sometimes described as “worms” or “rivers”)
  • Glare and the page appearing “too bright”
  • Skipping words or lines
  • Using finger following
  • Eyestrain
  • Rapid fatigue and eye rubbing

The symptoms of visual stress can be successfully alleviated with precision colour-tinted spectacle lenses and coloured overlays. The colour needed to alleviate the symptoms is individual-specific and are determined by our accredited Optometrists using the Intuitive Colorimeter.
