Abstract: When there is a possibility of intervention by accommodation in an eye to be examined, a message to the effect that caution is required is displayed. An optometric apparatus includes input means for inputting optometric information necessary for a subjective examination; judging means for judging the presence or absence of a possibility of intervention by accommodation in the eye to be examined on the basis of the information inputted by the input means; and warning means for prompting caution to an examiner on the basis of a result of judgement by the judging means.

Abstract: Disclosed herein is an ophthalmic apparatus for obtaining a refractive corrected-degree based on a refractive power of each of eyes to be examined, the ophthalmic apparatus comprising a refractive power inspecting device for inspecting the refractive power of the each eye, a program storing device for storing therein a program for measuring completely-corrected degrees of the eyes, adjusting the completely-corrected degrees according to factors for adjusting degrees to be corrected and thereby predicting degrees to be prescribed, an input device for inputting data about the factors for adjusting the degrees to be corrected, a program conducting device for advancing the program stored in the program storing device, a control device for sequentially activating the ophthalmic apparatus in accordance with the program and processing the result of inspection by completely-corrected degree inspecting device and the data input by the input device thereby to predict prescribed degrees, and a display device for display

Abstract: A joy stick mechanism for an ophthalmic apparatus moving an optical device of the ophthalmic apparatus horizontally and vertically, which mechanism is simple in structure but excellent in operational efficiency. Therefore, this mechanism comprises a drive device for moving the optical device vertically, a rotating knob rotatably provided on a shaft which substantially extends through a central portion of the mechanism, a detection device for detecting a direction and an amount of rotation of the rotating knob, and a control device for controlling the drive device on the basis of detection results of the detection device.
