Abstract
An optometric apparatus includes a luminous flux projecting unit for projecting a luminous flux to one eye of a subject to be measured, an imaging unit for imaging an anterior part of the eye illuminated by the luminous flux projecting unit, a position detecting unit for detecting the position of the eye in accordance with an image output from the imaging unit, an optometric unit for measuring the eye, a drive unit for driving the optometric unit, and a control unit for controlling the drive unit. The control unit controls the drive unit to align the optometric unit with the eye in accordance with a signal output from the position detecting unit and then controls the drive unit to move the optometric unit to the other eye of the subject when the measurement of the one eye by the optometric unit is completed.
