Abstract
The present invention provides an eye accommodation function state measurement device which places only a small burden on the subject, allows confirmation of an intermediate measurement result, and is more conveniently used. The eye accommodation function state measurement device disposes an image at a plurality of positions by using an image moving mechanism, and measures the accommodation function state of the subject's eye at each position. The eye accommodation function state measurement device includes a control section () which provides a measurement suspension period (Sto S) in which the measurement is suspended. In the measurement suspension period, the eye accommodation function state measurement device calculates the eye accommodation function state (S), displays the intermediate measurement result of the eye accommodation function state (S), or transmits data from the control section () to an external storage section () (S).
