Irlen Syndrome

Irlen Syndrome is a perceptual disorder.

Irlen Spectral Filters are only available through an Irlen Centre.

Please contact your nearest Irlen Centre for information and appointment in your local area.

Irlen® Spectral Filters are not available through any opticians in the UK . Irlen® Spectral Filters should not be confused with colorimetry lenses, they are very different.

Irlen Syndrome is a condition that affects the quality of life for around 14% (some estimates are higher) of the population but that is easily treated through assessment and Irlen® Spectral Filters.

Assessment process

The assessment and treatment of Irlen Syndrome is usually carried out in two stages.

Stage 1: Screening assessment – this is the overlay determination stage

Screenings are carried out by specialist Irlen® screeners. They will carry out a screening to identify symptoms and determine how symptoms are impacting upon daily life. Irlen Screeners are trained to determine whether an individual has a profile consistent with Irlen Syndrome or not and advise accordingly.

Stage 2: Full Tint assessment

A referral for a Full Tint assessment may be made if an individual has been screened as having a profile consistent with Irlen Syndrome.

At the Full Tint assessment the individual will choose their preferred combination of Irlen® Spectral Filters.

Irlen® Spectral Filters can be worn as glasses or contact lenses to reduce symptoms of Irlen Syndrome.

Prescription glasses can also be tinted if CR39 tintable, plastic, uncoated lenses are provided by an optician.
