Description
Technical field
This utility model relates to the examination equipment for eye field, particularly a kind of sight test means.
Background technology
The principle of optometry is an inspection light incident retrobulbar gathering situation, is standard with the emmetropia state, measures to be examined and gathers the different degree of scattered error between eye and emmetropia.Promptly make output as the comprehensive optometry appearance of one of eye refractometer, lens or post mirror are packed in the runner system,, change eyeglass more effectively, more quickly, reach the purpose of optometry through simple knob according to the principle of above-mentioned optometry.In the comprehensive vision eye refractometer of prior art, do not change the measuring ability of design to eyeball vision that pathological changes causes, function is perfect inadequately.
The utility model content
The main purpose of this utility model is to overcome the above-mentioned shortcoming of prior art, proposes a kind of Amsler of employing grid table and detects the sight test means whether eyeball macular diseases takes place.
This utility model adopts following technical scheme:
A kind of sight test means; Comprise compound table; Eye refractometer, operation control panel, projector and power supply box, power supply box link to each other with eye refractometer, operation control panel and projector respectively; It is characterized in that: said eye refractometer is provided with LED display; Said operation control panel comprises input/output interface, controls button, display screen and with said input/output interface, control button, the governor circuit that the display screen button links to each other, this governor circuit can obtain the test data of other equipment or send various test commands to eye refractometer or projector is realized various test functions and shown through display screen through input/output interface; This operation control panel also comprises Amsler grid table sighting target test set, and this Amsler grid table sighting target test set links to each other with said governor circuit.
Further; Said operation control panel display screen cooperates said Amsler grid table sighting target to be provided with Amsler grid table feeler switch; When touching this Amsler grid table feeler switch; Said Amsler grid table sighting target test set is sent to LED display through input/output interface and power supply box with Amsler grid table information, and said LED display presents Amsler grid table information to be tested.
Can know by above-mentioned description, compared with prior art, the utlity model has following beneficial effect this utility model:
This utility model has increased Amsler grid table test set on the basis of original automatic Synthesis eye refractometer; Through LED display Amsler grid table is appeared; During use; The operator adjusts LED display and is positioned at form the place ahead 30cm and touches Amsler grid table feeler switch, and LED display demonstrates Amsler grid table.The measured sees through the observation of eye refractometer form and is positioned at the Amsler grid table on the LED display of form the place ahead, can see whole form clearly under the normal condition, and the form lines of seeing are straight, and each lattice is square, big or small unanimity and corresponding symmetry.The person that has the metamorphopsia can find that in Amsler grid table lines are inhomogeneous or grid is not upright; Unusual person finds that in Amsler grid table lines are inhomogeneous, lines interrupt, the lines variable color; Grid distortion, grid distortion, incomplete or feel seemingly to have yarn curtain covering etc.; Judging that with this macula retinae portion has or not pathological changes and approximate range, is a kind of effective method simply again.
Description of drawings
Fig. 1 is the overall schematic of this utility model;
Fig. 2 is the structured flowchart of this utility model operation control panel.
The specific embodiment
Below this utility model is done further to describe through the specific embodiment.
With reference to Fig. 1, Fig. 2; A kind of sight test means; Comprise compound table 1; Eye refractometer 2, operation control panel 3, projector 4 and power supply box 5, power supply box 5 link to each other with eye refractometer 2, operation control panel 3 and projector 4 respectively; Eye refractometer 2 is provided with the folding LED display 6 that is positioned at form the place ahead; Operation control panel 3 comprises input/output interface 11, controls button 12, display screen 13 and with input/output interface 11, control button 12, the governor circuit 14 that display screen 13 links to each other, this governor circuit 14 can obtain the test data of other equipment or send various test commands to eye refractometer 2 or projector 4 is realized various test functions and shown through display screen 13 through input/output interface 11; This operation control panel 3 also comprises Amsler grid table sighting target test set 15, and this Amsler grid table sighting target test set 15 links to each other with governor circuit 14.Operation control panel display screen 13 cooperates Amsler grid table sighting target to be provided with Amsler grid table feeler switch; When pressing this Amsler grid table feeler switch; Amsler grid table sighting target test set sends LED display through input/output interface 11 and power supply box 5 with Amsler grid table information, and LED display presents Amsler grid table to be tested.
This utility model is adjusted LED display and is in form the place ahead 30cm in use, and the operator presses Amsler grid table feeler switch, and LED display demonstrates Amsler grid table.The measured sees through the observation of eye refractometer form and is positioned at the Amsler grid table on the LED display of form the place ahead, can see whole form clearly under the normal condition, and the form lines of seeing are straight, and each lattice is square, big or small unanimity and corresponding symmetry.The person that has the metamorphopsia can find that in Amsler grid table lines are inhomogeneous or grid is not upright; Unusual person finds that in Amsler grid table lines are inhomogeneous, lines interrupt, the lines variable color; Grid distortion, grid distortion, incomplete or feel seemingly to have yarn curtain covering etc.; Judging that with this macula retinae portion has or not pathological changes and approximate range, is a kind of effective method simply again.
The above-mentioned specific embodiment that is merely this utility model, but the design concept of this utility model is not limited thereto allly utilizes this design that this utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading this utility model protection domain.
