through a nozzle ejection unit for ejecting a patient has fluid in the eyes cornea to measure the pressure of a patient eye with ocular pressure measurement unit for, and an optical characteristic measuring section for measuring an optical characteristic of the subject eye, ocular pressure measurement unit and the optical characteristic measurement unit and the main body portion disposed, the pressure measurement unit and the eye optical characteristic measuring either the measuring section provided with a measuring unit and switching unit, the light receiving optical system for receiving light reflected from the surface and the projection optical system for projecting an index light to the cornea cornea to a state of the device to the subject eye when the eye pressure measuring part measuring state working distance detection unit which optically detects the working distance and the working distance is determined based on the detection results continue a transition state of the eye pressure measuring part measuring state and a control unit for controlling the measurement unit switching unit based on the determination result , the light reflected from the light-receiving optical system comprising a detecting unit for detecting, directly or indirectly, whether the reflected light from the corneal surface, and the light is received by the light-receiving optical system that is not the reflected light from the corneal surface is detected by the detecting unit If the controller does not care about the consequences ocular pressure sensing operating distance determination to continue to implement measures that apply a measurable negative status by measuring unit controls the switching unit to continue the implementation of ophthalmic devices.노즐을 통하여 피검자 안구의 각막에 유체를 분출하는 분출유닛을 갖고 피검자 안구의 압력을 측정하는 안구 압력 측정부와, 피검자 안구의 광학 특성을 측정하는 광학 특성 측정부와, 안구 압력 측정부와 광학 특성 측정부가 배치된 본체부와, 안구 압력 측정부와 광학 특성 측정부 중 어느 하나를 측정 가능 상태로 하는 측정부 절환유닛과, 각막에 지표광을 투사하는 투사광학계와 각막에서 반사된 지표광을 수광하는 수광광학계를 구비하
