The present invention regardless of palm size of the user and provide easily adjustable convergence binocular vision measuring instrument is held in one hand. A direction from one end of the substantially V-shape in contact with the nose to the other side and the measuring plate 1 gradually small width, the measuring plate indicator moves hole 5 bored in the center of one measurement plate and distance measurement memory for index position measurement attached to both sides of the index movement hole 5 of the first surface 1a, regulation congestion both with a strut 3 for supporting the index case 2 to slide in the index movement hole 5 in the eye vision measuring instrument, provided with at least one recess on each side edge of the measurement plate 1, by applying the finger in the recess to hold reliably measured plate 1. .BACKGROUND 1【課題】使用者の手掌サイズを問わず、片手で保持し易い調節輻輳両眼視測定器を提供する。【解決手段】鼻に接する略V字型の一端側から他端側へ向かって徐々に縮幅する測定板1と、測定板1の中央に穿設された指標移動用穴5と、測定板1の表面1aの指標移動用穴5の両側に付された指標位置計測用の距離測定用目盛りと、指標移動用穴5内をスライドする指標ケース2を支持する支柱3を備えた調節輻輳両眼視測定器において、測定板1の両側縁に少なくとも一つの凹部を設け、凹部に手指を当てて確実に測定板1を保持する。【選択図】図1
