Description

Pupil distance tester

Technical Field

The utility model belongs to the field of pupil distance detection, and particularly relates to a pupil distance tester.

Background

The interpupillary distance is the distance between the pupils of the eyes. When the eyes of a normal person watch the same object, the object is imaged at the retinas of the eyes respectively and overlapped at the central vision of the brain, so that the object is a complete single object with three-dimensional effect. The interpupillary distance is divided into: distance pupil distance, near pupil distance, commonly used pupil distance. In the measurement, the three kinds of interpupillary distances are measured at a certain distance. For myopic or hyperopic patients, the pupil distance of the patient needs to be measured when the glasses are matched, that is, the distance between the centers of the two lenses (the optical center distance) should be matched with the pupil distance of the patient, otherwise, even if the power is correct, the patient can feel uncomfortable after wearing the glasses, and the vision is affected.

When the conventional pupil distance meter is used, eyes of a person to be detected are abutted against one side face of the pupil distance detector, the person to be detected faces the person to be detected, the eyes are abutted against the other side face of the pupil distance detector, and pupil distance of the person to be detected is detected; the distance between the detected person and the detected person is about 20cm, and the detected person can feel uncomfortable when the distance is too close, and the risk of disease transmission exists; in addition, the height difference exists between the measuring personnel and the detected personnel, the measuring personnel can accurately detect the pupil distance of the detected personnel by adjusting the height of the measuring personnel in the measuring process, and the measuring personnel is very inconvenient; in the detection process, when the position observed by eyes of a measurer changes, the detected pupil distance also changes, and errors exist in the measured pupil distance, so that the detection accuracy is reduced.

Further, the controller is also used for obtaining the measured distance value and controlling the display to display the value.

The beneficial effects are that: the measured distance value is displayed through the display, so that a detector can know the measured distance in the current state and accurately adjust the measured distance to the required measured distance.

Further, the detection assembly further comprises a loudspeaker, the loudspeaker is arranged on the shell and is electrically connected with the controller, and the controller is further used for obtaining the measured distance value and controlling the loudspeaker to broadcast.

The beneficial effects are that: measurement distance under the current state is broadcasted through loudspeaker, makes the measurement personnel can know and accurately adjust measurement distance to required measurement distance.

Further, the LED lamp is arranged beside the camera, the LED lamp is electrically connected with the controller, and the controller is further used for controlling the switch of the LED lamp.

The beneficial effects are that: the LED lamp is used for providing the light source, provides the target of looking at for the personnel of examining, makes the camera can clearly shoot measuring process simultaneously, and the measuring process can be clearly observed to the inspector, and the testing result accuracy of obtaining is high.

Further, the shell body is provided with a supporting frame which is arranged above the examined window and used for fixing the forehead of the person to be examined.

The beneficial effects are that: the support frame is added, so that the head of the person to be detected has a force point in the detection process, and the detection comfort level is improved.
