Identification of visual stress which causes reading problems
Introducing Lucid ViSS
What is visual stress?
Visual stress (sometimes called ‘Meares-Irlen Syndrome’ or ‘Scotopic Sensitivity Syndrome’) is the experience of unpleasant visual symptoms when reading, especially for prolonged periods. Symptoms include illusions of shape, movement and colour in the text, distortions of the print, loss of print clarity, and general visual irritation. Visual stress can also cause sore eyes, headaches, frequent loss of place when reading, and impaired comprehension. Research has shown that 15 – 20% of people suffer visual stress to some extent, and they also tend to be hypersensitive to fluorescent lighting and flicker on computer monitors. Visual stress is not the same as dyslexia. Some people with dyslexia may suffer from visual stress and some may not. But dyslexia does seem to make the symptoms of visual stress much worse so it is especially important that those with diagnosed dyslexia are screened for visual stress.
Speedy and easy to use
Easy but comprehensive reporting
The ViSS reports module shows the extent to which the person’s performance was disrupted by visually stressful stimuli. A graphical scale of susceptibility to visual stress – from ‘low’ to ‘extremely high’ – makes it easy to interpret the results. A full statistical analysis is also shown. The implications of the different categories are explained in the Administrator’s Manual that accompanies the program, which also gives advice on the next steps to take. Comments may be included on the print-out of results, thus providing a complete record of the screening on one convenient A4 page. Professionals who require a more detailed breakdown of results will not be disappointed. A full individual item analysis can be accessed, making ViSS a very suitable tool for research.
