Since the display screen displayed on the section 207 can be switched to the display screen related to the ophthalmologic apparatus 100, efficient eye examination can be performed.

Further, for example, in the case where the ophthalmological system 10 includes a plurality of ophthalmic apparatuses 100 that can communicate (wireless communication is possible) with the mobile information terminal device 200, the processing/control unit 202 may perform the following processing. It is possible.
For example, the processing/control unit 202 first performs a recognition process to recognize which ophthalmological apparatus among the plurality of ophthalmological apparatuses 100 is located closer to the mobile information terminal device 200 than other ophthalmic apparatuses. As an example of this, the processing/control unit 202 performs recognition processing to recognize the ophthalmological apparatus 100 located closest to the mobile information terminal device 200 among the plurality of ophthalmological apparatuses 100. In this case, the processing/control unit 202 selects the ophthalmological device 100 that has been in contact with the mobile information terminal device 200 or the ophthalmological device 100 that is not in contact with the mobile information terminal device 200 and has the shortest distance to the mobile information terminal device 200.
