TRIAL LENS SETTING DEVICE

PURPOSE:To improve the quickness for searching a trial lens and to expect the exactness by constituting this device so that a lighting control means which fetches various eye examining information from an eye examining device turns on a display element in the corresponding position of a trial lens housing part corresponding to each eye examining information. CONSTITUTION:For instance, from a subjective eye examining device 23, eye examining information consisting of 9.0 SPH (refraction degree number) value and 2.75 CYL value of the right eye, and 8.0 SPH value and 3.0 CYL value of the left eye is sent to a CPU 37 through interface 36. The CPU 37 sends the above-mentioned eye examining information to a storage part 38, and also, sends its display control signal to a display controller 39, sends a turn-on signal to a display element 15a corresponding to 9.0 SPH value of the right eye and a display element 17b corresponding to 2.75 CYL value and allows them to turn on. Simultaneously, the display controller 39 allows both display elements 14b, 16a corresponding to 8.0 SPH value and 3.0 CYL value of the left eye to turn on. In such a manner an examiner can identify and fetch immediately without an error trial lenses 10a, 12b, 9b and 11a corresponding to the display elements 15a, 17b, 14b and 16a which are turned on.
