ReadEZ Software

The ReadEZ Screening Software lies at the heart of the ReadEZ system and is designed to be used by optometrists, orthoptists and other eye care professionals who are involved with the diagnosis and management of Visual Stress.

The software, which runs on most PCs running Windows 10 or later, simulates the effects of coloured overlays and spectacles by changing the background colour of the screen.

The software follows standardised protocols by first measuring “baseline” symptoms and reading speed/accuracy while viewing text against a white background.

The software then presents a full range of coloured backgrounds and the patient is asked to report which colour (if any) minimimises the symptoms. Symptoms and reading speed/accuracy is then reassessed with the preferred coloured background.

At the end of the test, the software displays the preferred colour and quantifies the improvement (if any) in symptoms and reading speed and accuracy with the preferred colour. On this basis, the practitioner can decide if the patient is likely to benefit form colour and prescribe an appropriate overlay or coloured lenses.

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. This provides a Baseline for symptoms.

The patient views a passage of text on the screen against a white background and is asked to read as fast and accurately as possible. The test records the number of errors made and the Rate of Reading (words/minute). This provides a baseline for reading speed and accuracy.

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.

Having determined the preferred colour, the patient then repeats the symptoms assessment with the preferred colour in order to establish if the ReadEZ colour has reduced the severity of symptoms.

The patient then repeats the rate of reading test with the preferred colour in order to establish if the ReadEZ colour improves the fluency of reading. An improvement of 10% is generally considered to be the threshold for prescribing a coloured overlay or lens.

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 overlay or tinted lens.

The software includes a powerful report generator allowing you to produce clear and attractive reports for the patient, parents, teachers etc.
