Device and method for examining the accommodation of an eye

摘要

The system has liquid drop (10) comprising a surface (26), where refraction characteristic of the liquid drop is influenceable by electrical fields. The liquid drop is arranged in a conical receptacle. A set of electrodes is arranged around the liquid drop and an electrical power supply is provided for producing different electrical fields and for applying different voltages at the electrodes. Independent claims are also included for the following: (1) an artificial eye with a liquid lens system (2) a measuring device for measuring accommodation of artificial eye (3) a diopter telescope with a liquid lens system.
