Description

上記課題を解決するために、本開示の１態様に係る検眼装置は、被検眼の屈折誤差を矯正する矯正光学系を備え、前記矯正光学系によって被検眼の屈折誤差を矯正して被検眼の加入度数を自覚的に測定可能な検眼装置であって、前記被検眼の加入度数が自覚的に測定される場合に、被検眼に付加される加入度数の初期値を、他覚屈折検査によって測定される被検眼の調節力に基づいて設定する設定手段を備えている。 In order to solve the above problem , an optometry apparatus according to one aspect of the present disclosure includes a correction optical system that corrects a refraction error of an eye to be examined, and corrects the refraction error of the eye to be examined by the correction optical system. An optometry apparatus that can measure the addition power subjectively, and when the addition power of the eye to be examined is measured subjectively, an initial value of the addition power added to the eye to be examined is measured by an objective refraction test Setting means for setting based on the adjusting force of the eye to be examined.

Claims
