Objective identification of visual stress that causes reading problems

Lucid's new easy-to-use computerised Visual Stress Screener represents a scientific breakthrough in objective identification of children (ages 7 to 17) who are susceptible to visual stress when reading. Visual stress, which affects 15 - 20% of the population, hinders children's literacy development and is a barrier to efficient and enjoyable reading. ViSS gives an accurate and reliable indication of the existence and severity of visual stress and predicts those who should benefit from using coloured overlays or tinted lenses to ameliorate the symptoms of visual stress. ViSS is the outcome of psychological research on visual search as a predictor of visual stress carried out at the University of Hull over three years.

ViSS has been researched and developed by Lucid Research Ltd, a company with an international reputation for creating innovative computer-based systems for assessment and screening in education and psychology. Lucid's products, which are used in over 7,000 schools, colleges and universities are backed by extensive scientific research.
