A subjective optometer includes a visual target, deflectors, calculator and positioning parts. The visual target is presented a first distance away from eyes. The deflectors deflect first optical paths formed between the eyes and the visual target to form second optical paths causing the eyes to observe the visual target as if the visual target is presented at a second distance shorter than the first distance. The calculator calculates accommodation stimulus amount for causing the eyes to observe the visual target as if presented at the second distance based on convergence accommodation amount of the eyes caused by the second optical paths, the first distance and the second distance. The positioning parts include spherical lenses and position spherical lenses having spherical powers corresponding to the accommodation stimulus amount in the second optical paths. The eyes are examined with the spherical lenses positioned in the second optical paths.
