Claims (1)
偏光フイルターを介して行う立体視検査に用いら
れる視表において、偏光軸の角度が互いに異なり
、左右方向にずらして配置した一対の偏光視標か
らなる第１の偏光立体視視標と、前記偏光視標を
左右方向に入れ換えた第２の偏光立体視視標とを
有することを特徴とする立体視検査視表。 In a visual chart used for stereoscopic vision testing performed through a pair of polarizing filters for the left and right eyes with different angles of the polarizing axes, a pair of polarizing visual targets with different angles of the polarizing axes and shifted in the left-right direction are used. What is claimed is: 1. A stereoscopic vision test chart comprising: a first polarized stereoscopic chart; and a second polarized stereoscopic chart, which is obtained by transposing the polarized stereoscopic chart in the left-right direction.
