PROBLEM TO BE SOLVED: To provide a technique capable of reducing a burden applied to a subject when evaluating reliability of a vision test using a perimeter.SOLUTION: A vision testing apparatus includes: a perimeter for measuring a prescribed site of an eye a plurality of times by changing numerical conditions to acquire one measurement result； a storage section for storing answers of a subject to the respective numerical conditions in the plurality of times of measurement； an allocation section for allocating a role as a base of a reliability index to at least any of the respective numerical conditions related to the answers of the subject stored in the storage section； and a reliability index acquisition section that refers to the answers of the subject to the allocated numerical condition allocated by the allocation section, from the storage section and acquires a reliability index to the vision test on the basis of the answers. The related technique of the vision testing apparatus is also provided.SELECTED DRAWING: Figure 1【課題】視野計を用いた視覚検査の信頼性を評価する際の被検者への負担を軽減可能な技術を提供する。【解決手段】眼の所定の部位に対し、数値条件を変更して複数回の測定を行い、一の測定結果を得る視野計と、複数回の測定における各数値条件に対する被検者の回答を記憶する記憶部と、記憶部に記憶された被検者の回答に係る各数値条件の少なくともいずれかに対して信頼性指標の基としての役割を割り当てる割当部と、割当部により割り当てられた割当数値条件に対する被検者の回答を記憶部から参照し、当該回答に基づき、視覚検査に対する信頼性指標を得る信頼性指標取得部と、を備えた、視覚検査装置およびその関連技術を提供する。【選択図】図１
