PROBLEM TO BE SOLVED: To provide an ophthalmologic device to be operated securely in a dark room. SOLUTION: The device has display LED's to be lighted or blinked corresponding to each operation switch of a timer, an exciter filter, or a barrier filter, and illumination LED's for illuminating letters indicating the function of each operation switch. In a series of operations, only the illumination LED for the operation switch 39 of the exciter filter to be operated first is lighted (S6). When the switch 39 is operated (S7), the display LED of the switch is lighted, then the display LED's of the operation switches 37 and 40 to be operated in the next operation are blinked (S8). Therefore, as an examiner can perform the measurement by pressing the operation switches blinked one after another, the examiner can perform the ophthalmologic measurement accurately in a dark room.
