How it works

The ReadEZ Screening Software simulates the effects of coloured overlays and spectacles by changing the background colour of the screen. To determine the optimum colour, a sample of text is displayed on the screen while the colour of the background is changed systematically. The observer is asked to report which colour is most comfortable or minimises their symptoms. The effectiveness of the colours is assessed using a variety of test stimuli and reading tests. Computer screening is fast, thorough and sensitive and compares very favourably with manual screening.

Step by step ...

Baseline symptoms

The patient views a passage of text on the screen against a white background and is asked to rate the severity of any symptoms they may experience.

Baseline rate of reading:

The patient is required to read a paragraph or random words against a white background. The number of words read in one minute and the number of errors made is recorded. This forms a baseline for the fluency of reading.

Automated screening:

Two colours are presented and the patient is required to select the “more comfortable” colour. The computer uses a sophisticated algorithm to compare different combinations of colours in order to determine the best colour overall. This algorithm generates a number of indices describing the consistency of the patient’s responses.


Rate of reading with preferred colour:

Having determined the preferred colour, the program repeats the rate of reading test with this colour in order to establish if the ReadEZ tint improves the fluency of reading. An improvement of 10% is generally considered to be the threshold for prescribing a coloured overlay.

The software includes a powerful integrated database for storing results and generating reports. Full details of every screening are stored automatically avoiding the need to take any notes during the test


The program presents a visual comparison of the symptoms and rate of reading result with and without a coloured overlayor tinted lens.



The software includes a powerful report generator. Produce clear and attractive reports using the templates included or design your own reports.

Testimonials ...

We were getting a lot of requests to check for Meares-Irlen syndrome but could not really justify spending thousands on the testing kit. Then along came ReadEZ which gave us everything we need for under £500. It works brilliantly!

The ReadEZ software brings Meares-Irlen testing kicking and screaming into the 21st century.

I was always a bit embarrassed charging patients for waving around a series of overlays. The ReadEZ screening system looks so much more professional and I can give each patient a detailed report of their results.

Since becoming a ReadEZ Test Centre, I have received an influx of patients. If you manage to help one patient word spreads like wildfire. It has been a great practice builder.

A really slick bit of software. Obviously developed by people who understand the condition.
