OPTOMETRY SYSTEM AND OPTOMETRY PROGRAM

This optometry system, for presenting a test chart to an eye being tested and subjectively measuring an optical characteristic of the eye being tested, is provided with a setting means which sets a reference value based on the subject's reaction time to a test chart, a reaction input means which inputs the response of the subject reading the test chart, a control means which automatically advances the test on the basis of an input signal from the response input means, and a guidance information output means which, on the basis of the reference value set by the setting means, outputs guidance information for guiding the subject to input a response during testing of the eye being tested. Hereby, it is possible to accurately carry out a subjective test on the eye being tested.
