What is Irlen® Syndrome?

Millions of people use Irlen® Lenses for Irlen Syndrome
But what is it?  It 
  • is not a learning disability
    but can cause specific learning problems.


  • is not a visual difficulty
    but can cause  visual stress.


  • is a visual perceptual dysfunction
    affected by lighting, glare, high contrast, patterns
    and colours.

  • is not an "eye problem"  but a problem with 
    the brain processing visual information. 

  • affects how you perceive the printed page.
     It's tiring because you have to keep adapting to
    distortions from print in the background.


  • can cause you to confuse letters, words and sentences, and numbers.

  • can be worse under bright or flourescent lights

  • makes it harder for you to deal with moving objects - balls, people, escalators etc. Bad for sportspeople!

  • puts another layer of stress, “visual stress” into the system and can increased symptoms for other difficulties such as PRSD or TBI.

  • can be easily and effectively dealt with through use of colour.
