Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an optometer, when performing monocular examination, with both eyes opened, capable of easily setting a fogging state suited to a subject, and an optometry program.SOLUTION: The optometer for examining subject's eyes, includes: a pair of left/right lens units disposed on optical paths of luminous flux of optotypes projected to the subject's eyes and changing optical characteristics of the luminous flux of the optotypes; control means for controlling drive of the lens units; and acquisition means for acquiring target visual acuity values in fogging. The control means determines an amount of fogging for fogging the subject's eyes on the basis of the target visual acuity values acquired by the acquisition means.SELECTED DRAWING: Figure 7
【課題】 両眼解放下での片眼検査を行う際に、被検者に適した雲霧状態を容易に設定できる検眼装置、および検眼プログラムを提供する。【解決手段】 被検眼を検査するための検眼装置であって、被検者に投影される視標光束の光路中に配置され、前記視標光束の光学特性を変化させる左右一対のレンズユニットと、前記レンズユニットの駆動を制御する制御手段と、雲霧時の目標視力値を取得する取得手段と、を備え、前記制御手段は、前記取得手段によって取得された前記目標視力値に基づいて、前記被検眼を雲霧させるための雲霧量を決定することを特徴とする。【選択図】 図7 |
