irlen syndrome & colourimetry

Irlen Syndrome is said to affect 20% of the population – 13 million people in UK. It is not the same as dyslexia but it affects about 40% of dyslexics. It is also known as visual dyslexia and scotopic sensitivity syndrome. 

people with irlen syndrome may experience one or several of the following:

  • Blurred letters or words which go out of focus.
  • Letters which move or present with back to front appearance and shimmering shaking or swirling text.
  • Headaches from reading.
  • Words or letters which break into two and appear as double.
  • White rivers breaking up text.
  • Difficulty with tracking across the page.
  • Upset by glare on the page or over-sensitive to bright lights.
  • Stomach disturbance or hearing issues with no obvious cause (it affects the central nervous system)
  • ADD/HD

At Houghton Opticians we offer an Irlen Syndrome & Colourimetry Assessment Service. The initial assessment is 1 hour long with a number of Irlen tests involved to diagnose Irlens plus a colour overlay assessment. If a colour is found to help, we then use a Cerium Intuitive Colourimetry machine and work with lenses too to find the exact hue and shade which calms the symptoms. This colour can then be used to make up precision tinted lenses. A comprehensive report is provided for information and can be forwarded to schools or colleges with numerous examples of adjustments that can be made for the individual at home or in school. We also provide any overlays that are required

People with reading difficulties sometimes have a weakness in eye co-ordination or focusing so we would treat this with eye exercises or glasses.


Our costs:

£95 for the initial 1 hour assessment, 2 page report and overlays

£50 for the 30 minute Intuitive Colourimeter and lenses assessment

£130 for the precision tinted lenses from Cerium
