Irlen Syndrome


Irlen Syndrome, also referred to at times as a Meares-Irlen Syndrome, Scopic Sensitivity Syndrome and Visual Stress, is a perceptual processing disorder and NOT an optical problem.

Irlen Syndrome is supported by 30 years of research and identified as a perceptual processing disorder caused by the brain's inability to process specific wavelengths of light.

This means that there is a problem with the brain's ability to process visual information and tends to run in families. It is not currently identified by other standardised educational or medical tests; therefore, information and awareness of the condition is not always accessible through traditional routes.

Please see the Irlen Syndrome website for specific information, along with a self-assessment questionnaire, which is the first step in exploring whether you or someone you know has the condition and whether screening would be helpful. You can find it at

How Irlen Syndrome can impact

Irlen Syndrome can affect many different areas, including:

• Academic work performance

• Behaviour

• Attention

• Ability to sit still

• Concentration

Presenting challenges and issues

The challenges and difficulties can present in many ways, therefore, if you or someone you know experience any of the following, it is always useful to have a screening, in addition to exploring other possibilities.

• Print looks different

• Environment looks different

• Slow or inefficient reading

• Poor comprehension

• Eye strain

• Fatigue

• Headaches

• Difficulty with math computation

• Difficulty copying

• Difficulty reading music

• Poor sports performance

• Poor depth-perception

• Low motivation

• Low self-esteem

Key signs and Symptoms

Some of the key symptoms of Irlen Syndrome can be identified through:

• Light Sensitivity

• Reading problems

• Visual and Physical Discomfort

• Attention and concentration problems

• Sensory Overload & Sensitivity

• Writing problems

• Depth Perception difficulties

• Distortions under visual demand such as words, text or items blurring, fuzzy, waving, wiggling, jiggling and moving

What happens during and after an assessment?

After you have completed the self-assessment questionnaire, we will discuss whether you need a screening, making an appointment if necessary.

During the assessment, you will be asked lots of questions to help us gain an understanding of your strengths and struggles and what would help you feel more comfortable. This enables us to get an accurate understanding of what needs to change and strategies necessary to support this.

You will then complete a range of activities and tasks, alongside being asked questions about your experiences. This helps us to identify where specifically your difficulties are and what needs to have happen, to reduce the discomfort and frustrations you may have, which contributes towards our final written report.

We will then look at the use of overlays, assessing whether this is enough to help reduce your difficulties, making recommendations on the most appropriate colours for you. In addition, we will look at techniques and strategies you can use on a daily basis, to reduce the level of visual stress you are experiencing, enabling you to make environmental adjustments.

For most people, this would be enough. However, some people have such difficulties, they need the use of glasses for everyday tasks to reduce the level of stress experienced from their external environment. If this is the case, we would discuss this with you and signpost you onto a diagnostician, who could then assess for lenses. This is not available on the NHS and would be a private cost to you.

Based upon our assessment, we then write a comprehensive and detailed report, which will be sent to you within 14 days of your assessment.

The Irlen Method
The Irlen Method is non-invasive technology that uses coloured overlays and filters to improve the brain's ability to process visual information. It is the only method scientifically proven to successfully correct the processing problems associated with Irlen Syndrome.

The foundation of the Irlen Method is its precision-tinted coloured overlays and filters. We use advanced colour spectrometer technology to ensure that our overlays and coloured glasses meet strict standards of colour balancing designed to produce the most effective colour-correction tool.

Benefits of using the Irlen Method
This technology can improve reading fluency, comfort, comprehension, attention, and concentration while reducing light sensitivity. This is not a method of reading instruction. It is a colour-based technology that filters out offensive light waves, so the brain can accurately process visual information
