    摘要: The present invention provides a method and apparatus for measuring operating vision. An optotype mark is displayed (step 103). A subject's response to the optotype mark is accepted via an input device (step 104). A determination is made as to whether or not the response is correct (step 105). When the current response of the subject is correct and the previous response or one of the previous response and the last-but-one response is incorrect, an optotype mark corresponding to the same visual acuity is presented (step 112). When the previous response is correct or both the previous response and the last-but-one response are correct, an optotype mark corresponding to a visual acuity one level higher is presented (step 110). When the current response is incorrect, an optotype mark corresponding to a visual acuity one level lower is presented (step 111).
