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 displaying the prescribed degrees predicted by the control device. Thus, an examiner having little experience in and unfamiliar to the optometry can easily obtain suitable prescribed values.
