Description
Summary:The people’s daily routine is characterized by an exposure to short reading distances during a long time period. This is due because of excessive reading and writing work and also because the use of mobile display screens. The human visual activity has changed a lot during last decades, demanding to the visual system (both accommodative and vergencial level) an extra effort. To correct the associated effects of working with short distances, we present a Real Time Control device “RTC device” which consists of an optical measurement system and algorithmically correction for improving working distance. The RTC device contains a head tilt measurement system that monitorizes in real time. Our main goal is to design an optical device that could improve the visual performance of people by controlling the reading distance, and thus avoiding visual-functional and postural complications since the childhood.
