Eye accommodation function state measurement device

An eye accommodation function state measurement device comprising:

• a target projection section which projects a target onto a subject's eye, and a target moving mechanism which moves a position of the target along a direction of an optical axis of the subject's eye, the eye accommodation function state measurement device disposing the target at a plurality of positions by using the target moving mechanism, and measuring an accommodation function state of the subject's eye at each position, the eye accommodation function state measurement device including a position select section which can select the initial position of the target from a plurality of positions determined based on a measurement far point position of the subject's eye measured by preparation measurement before main measurement.
