Abstract
The utility model relates to an eyesight detector capable of raising optometry accuracy, comprising an eyesight dial. The eyesight dial is provided with a measuring window. The eyesight detector capable of raising optometry accuracy is characterized in that the eyesight dial is also provided with a face position adjusting apparatus, the surface of which protrudes from the surface of the eyesight dial. Accordingly, at the time of eyesight inspection, the forehead of an examinee is attached to a forehead rack and the cheek is attached to the face position adjusting apparatus to stabilize the head and enable the visual line to be horizontal. The eyesight detector is advantageous in that when the visual line is horizontal, the visual line can be easier to be in parallel with or superposed with a lens axle, and eyesight accuracy can be improved; through the face position adjusting apparatus, the head of a patient can be positioned and the position of the head can be determined more conveniently, and thereby optometry can be more accurate and eyesight inspection time for a patient can be shortened; the surface of the face position adjusting apparatus is provided with a groove, which increases comfort level of the eyesight detector in use.
Description
Technical field
This utility model relates to the vision tester that can improve the optometry accuracy.
Background technology
General full-automatic comprehensive vision tester is the equipment of rudder angle formula test patient glasses, and spherical lens cylindrical lens prism is arranged, and the crossed cylinder lens sheet is contained in a plurality of DISK dishes, and adopts the lens principle of stacking of light path.By the control of control panel, different lens mutually superpose and form the diopter combinations that needs; Optometry patient interpupillary distance is carried out interpupillary distance adjustment and measurement.A kind of full-automatic comprehensive vision tester 10 as shown in Figure 1, comprise horizontal strut 11, vision dial plate 12 and forehead supports 14, horizontal strut 11 is connected by forehead supports 14 with vision dial plate 12, horizontal strut 11 is positioned at the top of vision dial plate 12, is provided with measurement window 13 on vision dial plate 12.Be provided with different dioptric lens (not shown)s in measurement window 13.
During measurement, as shown in Figure 2, before the patient was seated at full-automatic comprehensive vision tester, forehead withstood on forehead supports 14, and head is fixed, and eyes see through measurement window 13 and observe sighting target on mirror disk.Because forehead is outstanding forward with respect to eyes, cheek, when forehead leans against on forehead supports 14, be to keep balance, the patient can lean against cheek vision dial plate 12 surfaces usually simultaneously.Therefore, patient's head inevitably is skewed.The eyeglass axle of the lens in measurement window 13 is to be horizontally disposed with, so there is angle in patient's direction of visual lines with vision dial plate 12 scope bobbins, can't keeping parallelism or coincidence, so cause check result to have error.
In addition, optometrist is seated at the another side of full-automatic comprehensive vision tester, regulate the control handle of regulating on control panel after the main frame level and regulate interpupillary distance to the tram, regulate diopter to certain number of degrees, whether the inquiry measured can see the icon on projector clearly, finishes an optometry until the measured can see icon very easily; In whole measuring process, require the somascope level, can not tilt.And for patient's sight line up and down and 12 scope bobbin keeping parallelism or coincidences of vision dial plate, optometrist is often adjusted patient's chin position and is kept optometry again after the sight line level.Patient's sight line up and down and vision dial plate 12 scope bobbin keeping parallelisms or coincidence and accurately optometry when patient's eyes and measurement window 13 are apart from 12MM usually; even adjustment patient's chin position has kept eyes and measurement window 13 distances; the patient has delicate activity also can cause patient's sight line up and down and the vision dial plate scope bobbin can't keeping parallelism or coincidence; measuring the result of coming after repeatedly adjusting does not only have credibility, and needed chronic.
The utility model content
First purpose of the present utility model is in order to overcome deficiency of the prior art, a kind of vision tester that improves the optometry accuracy to be provided.
For realizing above purpose, this utility model is achieved through the following technical solutions:
Can improve the vision tester of optometry accuracy, comprise the vision dial plate, be provided with measurement window on described vision dial plate, it is characterized in that, also be provided with the face location adjusting device on described vision dial plate, described face location adjusting device surface protrudes from the visual acuity chart panel surface.
Preferably, the number of described vision dial plate is two, is provided with at least one face location adjusting device on each vision dial plate.
Preferably, described face location adjusting device is connected with the vision dial plate by the mode of pasting.
Preferably, described face location adjusting device surface is provided with groove.
Preferably, the bottom of described face location adjusting device is provided be used to the Magnet or the rubber layer that stick on the vision dial plate.
Preferably, described face location adjusting device is that flexible material is made.
Preferably, described face location adjusting device is that silica gel is made.
Preferably, described face location adjusting device comprises integral type pad or assembled pad.
Preferably, described assembled pad comprises annulus and egative film; Described annulus is provided with storage tank, and described egative film embeds in storage tank.
Preferably, also comprise horizontal strut, forehead supports, described horizontal strut is connected by forehead supports with the vision dial plate, and described horizontal strut is positioned at the top of vision dial plate, and described horizontal strut is T-shaped; Described measurement window is positioned at above the face location adjusting device.
Vision dial plate of the present utility model is a plurality of examination of visual acuity eyeglasses of a pair of employing, and the forehead supports upper surface is soft material surface, and is more comfortable when making patient's forehead paste thereon.The face location adjusting device is set on the vision dial plate, and the face location adjusting device protrudes from the visual acuity chart panel surface, therefore, when testing eyesight, those who are investigated's forehead is attached on forehead supports, cheek is attached on the face location adjusting device, can make head keep stable, and the sight line level.Be more prone to make sight line parallel with the eyeglass axle or overlap during the sight line level, improve the accuracy of eye.By face location adjusting device position patient head, can determine more easily patient's head position, more accurate optometry and shortening patient's vision review time.Face location adjusting device surface is provided with groove, can improve the comfort level when using.
