Provided is an instillation assistance tool which has a simple structure and with which an ophthalmic solution can be accurately administered to a subject's eye. This instillation assistance tool (1) is formed such that, in a condition in which the subject is in a supine position and an ocular guide (20) has been brought into contact with the area surrounding the eye, a droplet of the ophthalmic solution in an ophthalmic solution container (30) drops onto the eye at a position (A) shifted toward the upper eyelid by a predetermined distance from the center position (X) of the surface of the eye.本發明提供一種能以簡單之構造將點眼液正確地投予至點眼藥對象者之眼睛的點眼藥輔助具。本發明之點眼藥輔助具(1)係以於點眼藥對象者以平躺之姿勢將目鏡導件(20)抵接於眼睛之周圍之狀態下，點眼藥容器(30)之點眼液之液滴滴落至自上述眼睛表面之中心位置(X)朝上眼瞼側偏移特定距離之位置(A)之方式，形成目鏡導件(20)。
