摘要

A subjective optometry apparatus subjectively measures optical characteristics of a subject eye. The subjective optometry apparatus includes a light projecting optical system, an optical path switching portion that switches between a first optical path having a first examination distance and a second optical path having a second examination distance, and an examination distance changing portion that optically changes the first examination distance or the second examination distance. Based on examination distance information, the examination distance changing unit causes the optical path switching portion to set an optical path to either the first optical path or the second optical path, and drives a distance changing optical member in the set optical path to optically change the examination distance to an examination distance different from the first examination distance and the second examination distance.
