The invention relates to an optometer for comprehensively detecting diopter and
visual function of eyes. The optometer comprises an
optometry lifting table, a seat, a computer optometer, a control panel, a function control button, a function execution mechanism and a sighting target
assembly, and is characterized in that the sighting target
assembly comprises a front sighting target plate and a rear sighting target plate which are provided with sighting target windows, as well as a sighting target card with sighting targets, wherein, the front sighting target plate and the rear sighting target plate are suspended on a
near sight test rod; and at least one group of the sighting targets among all the sighting targets are single sighting targets. The optometer further comprises an adjustment sensitivity checking device. The
optometry method using the optometer mainly comprises the following steps: (1) diopter detection; and (2)
visual function detection. The sighting targets in the structure are changed into single sighting targets so as to improve the judgment accuracy; and meanwhile results can be accurately and effectively checked by the added adjustment sensitivity checking device in a non-hand-held manner. Therefore, by adopting the
optometry method, the diopter and the internal visual
functional status of eyes can be more comprehensively checked so that the visual health state of eyes can be assessed comprehensively and a reasonable solution can be made further.
