The utility model relates to a detection device for cryptotropia.Including: a transparent detector,It has a front and a back.There is a sign on the front.The sight mark has a center point；A cursor,Having a gripping part and a light source end at one end of the gripping part,The light source end emits a light source；1. Glasses worn by the subject；The left and right sides of the glasses are respectively a first lens and a second lens.The subject can see the sight mark from the first lens.The subject can see the cursor from the second lens；With the above configuration,The cursor is operated by a subject so that the light source end contacts the back of the detector.The light source passes through the detector.A cursor is formed on the front of the detector.Whether or not the cursor is at the center of the object,To determine whether the subject has esotropia.一種隱斜視檢測裝置，包括：一可透光之檢測器，具有一正面和一背面，該正面設有一視標，該視標具有一中心點；一光標器，具有一可握持部以及位於該可握持部之一端的光源端，該光源端發出一光源；一由受檢者配戴之眼鏡，該眼鏡之左右邊分別為一第一鏡片和一第二鏡片；受檢者從該第一鏡片可看見該視標，受檢者從第二鏡片可看見該光標；藉由上述構造，該光標器被一受檢者操作使該光源端接觸該檢測器之背面，該光源通過該檢測器，於該檢測器之正面形成一光標，以該光標是否位於該視標之中心點，判斷該受檢者是否具有隱斜視。
