Claims

[Scope of utility model registration request]

The main body and the operation panel are connected by a cable, and the main body is a rotary polyhedron made of a combination of multiple faces displaying Landolt ring or equivalent visual acuity test targets, and is equipped with a window that allows viewing only one face of the polyhedron. The front polyhedron is constructed by being housed in a housing, and each time a switch corresponding to the visual acuity to be tested is operated on the operation panel, the front polyhedron changes one face at a time, and the optotype to be tested is illuminated from inside the polyhedron. This visual acuity tester is characterized by a lamp that lights up, and a numerical display of the visual acuity at this time and the direction of the break in the Landolt ring on the operation panel.
