In the last decades, the majority of the multinational technology companies have filled the global market with consumer electronics. In the developmental history of such companies has been recorded the design of electronic devices, that changed for the better our everyday life. Hence, most of these devices -such as personal computers, electronic readers, smartphones and tablets- have nowadays become an integral and irreplaceable part of our daily life.
Day after day these electronic devices tend to be increasingly used by more people worldwide. Although they have contributed to make simpler our everyday routine, it has been also proved that they negatively affect our vision. Preliminary studies have reported eyesight symptoms, associated with ocular accommodation. Thus, recently in GIO labs a study has been conducted to examine if differences in accommodation response exist after subjects using different types of electronic devices. For the needs of this study a Hartmann-Shack wavefront sensor was employed, which was implemented into a prototype adaptive optics system. The results of this study yield an alternative approach of testing the accommodation response and the optical quality of the human eye in real time conditions, related with the change in society’s lifestyle by technology.
