Reading is one of the most valued activities in human society. Not only does it facilitate effective handling of various daily tasks at home, school and work, but is also an important form of recreation. In recent years, reading has become an important clinical tool for examining functional capability and evaluating the effectiveness of interventions on functional performance. To assess the impact of vision on reading acuity, a new and reliable Traditional Chinese reading chart was developed and validated for measuring the reading performance of Chinese communities. A tablet app is under development in order to popularize the reading measurement.
