Patent abstract
An test tool for optometry includes a lens holding frame and a clip. The lens holding frame pivotally supports a trial lens to be mounted. The clip is attached to a rear side of the lens holding frame to clamp glasses. The lens holding frame has a pair of axi-symmetrical C-shaped rims having open ends and opposing closed ends, and a connecting portion that connects the opposing closed ends of the rims. Each rim has an inner surface that forms an accommodating space for holding the trial lens to be pivotal and movable in a left-to-right direction.
