Irlen syndrome is closely associated with precision tinted lenses selected by individual evaluation. It has a much broader claims that includes many other conditions than reading problems.
Because success with tinted lenses is so ill defined for reading problems and success can be claimed as soon as someone says they prefer one color over another, I don't use the term.
For example some statistics claim 60% of the population has Irlen syndrome that could benefit from specific tinted lenses. These claims have been extended to also include ADD and ADHD. Specific expected benefits with precision tinted lenses are not defined for an individual with a specific problem and there is no guarantee that they will have their problem removed.
