Description

  The present invention relates to an optometry apparatus, method and program used for examination of an eye to be examined.

  Conventionally, an eye function such as the eye refractive power of an eye to be examined is measured by a subjective test or an objective test, or by using both tests in combination. As an example, the subjective test described in Patent Document 1 measures eye refractive power based on the response of the subject to various targets such as Landolt's ring. For this reason, the subjective test takes time for measurement and requires the proficiency of the examiner.
