PROBLEM TO BE SOLVED: To provide an optometer that allows an eye to be examined being examined to be observed in an optional direction relative to a subject without being affected by a type of an optometer.SOLUTION: There is provided an optometer 10 equipped with an optometrical unit 20 that allows a vision function of an eye 2 to be examined to be corrected by arranging a plurality of optical elements 22 in front of the eye 2 to be examined selectively. The optometrical unit 20 is configured so as to reflect an optical axis B of a corneal collimation system forward, and observe a corneal apex position from a direction opposed to the eye 2 to be examined, and is attached with a deflection unit 30 removably for deflecting the optical axis B. When the deflection unit 30 is attached to the optometrical unit 20, the corneal apex position can be observed from a direction other than the direction opposed to the eye 2 to be examined.SELECTED DRAWING: Figure 1ACOPYRIGHT: (C)2020,JPO&INPIT【課題】検眼装置によらず、検眼中の被検眼を被検者に対する任意の方向から観察することができる検眼装置を提供する。【解決手段】複数の光学素子２２を被検眼２の眼前に選択的に配置することで被検眼２の視機能を矯正可能とする検眼ユニット２０を備えた検眼装置１０において、検眼ユニット２０は、角膜視準系の光軸Ｂを前方に反射し、角膜頂点位置を被検眼２に対向する方向から観察可能に構成されると共に、光軸Ｂを偏向する偏向ユニット３０が着脱可能に取り付けられる。そして、検眼ユニット２０に偏向ユニット３０を取り付けたとき、角膜頂点位置を被検眼２に対向する方向以外の方向から観察可能とする。【選択図】図１Ａ
