Test Chart LITE
An ideal solution for hospital eye departments and other clinics where the main requirement is to measure visual acuity.
Why Thomson Test Chart LITE?
Thomson Test Chart LITE was developed in response to demand from hospitals eye departments, occupational health departments, diabetic screening units and GPs for a simple computer-based system for measuring visual acuity.
The program is based on the full Thomson Test Chart software and retains the same user interface. Thomson Test Chart LITE includes the same wide range of test charts, the number plate test and the fixation stimuli, It does not include the refraction stimuli and more advanced vision assessment tools.
Prof Thomson developed the first computer-based Test Chart in the early 1990s and released the first version for sale in 2000. Over 8000 eye care professionals in the UK alone now use the system making it the most popular computer-based test chart by miles!
The software benefits from over 20 years of research and development. While other companies have copied the concept, reviews consistently rate the Thomson chart as the most comprehensive and most intuitive to use.
