PROBLEM TO BE SOLVED: To present a visual target for performing binocular function examination with a simple configuration using a polarizing optical member.SOLUTION: An optometer includes: a display capable of displaying a visual target for a right eye and a visual target for a left eye for examining visual functions of both examined eyes on display regions separated from each other and a polarizing optical member in which an optical region for the right eye disposed correspondingly to the display region of the visual target for the right eye and an optical region for the left eye disposed correspondingly to the display region of the visual target for the left eye are disposed separately from each other, and which converts light from the visual target for the right eye and the visual target for the left eye displayed on the display into light having polarizing axes orthogonal to each other. When performing binocular function examination, polarizing filters having polarizing axes respectively coinciding with the polarizing axes orthogonal to each other from the polarizing optical member are disposed in front of the right and left examined eyes and are used.COPYRIGHT: (C)2014,JPO&INPIT【課題】 偏光光学部材を用い、簡単な構成で両眼視機能検査を行うための視標を呈示できる【解決手段】 被検眼両眼の視機能を検査するための右眼用視標と左眼用視標を互いに分離された表示領域に表示可能なディスプレイと、前記右眼用視標の表示領域に対応して配置される右眼用光学領域と、前記左眼用視標の表示領域に対応して配置される左眼用光学領域と、が互いに分離して配置され、前記ディスプレイに表示された前記右眼用視標と前記左眼用視標からの光を、互いに直交する偏光軸の光に変換する偏光光学部材と、を備え、両眼視機能検査時に、前記偏光光学部材からの互いに直交する偏光軸にそれぞれ一致した偏光軸を持つ偏光フィルタが被検眼の左右の眼前にそれぞれ配置されて使用されることを特徴とする。【選択図】 図11
