Document Type and Number:
Japanese Patent JP4739795
Kind Code:
B2
Abstract:
An eye refractive power measurement apparatus capable of checking a presenting position (presenting distance) of a fixation target. The eye refractive power measurement apparatus has a measurement optical system for measuring eye refractive power of an examinee's eye, a fixation target presentation optical system for presenting a fixation target to the examinee's eye, a changing unit which changes a presenting position of the fixation target in a direction of an optical axis of the presentation optical system, a display, and a controller which controls to display a change of the presenting position as a diopter change on the display graphically.
