Abstract
The utility model relates to a short-distance used visual acuity tester, which is used for checking various visual targets of eyesight in a short distance. An existing visual acuity tester which is single in function commonly only has the single function of myopia detection, polarization detection, red-green balance detection or the like, and is troublesome in use and lower in detection efficiency. The short-distance used visual acuity tester comprises a casing and an upper cover, and is characterized in a through hole is arranged on the surface of the upper cover, a display panel component is embedded into the through hole, polarization (red-green) icons and a short-distance used visual chart are arranged on the display panel component, and a main circuit board is further arranged in the casing and connected with the display panel component. The short-distance used visual acuity tester integrates the functions of various commonly used optometry units, has various functions of red-green polarization detection, myopia detection, dioptric detection and the like, and is convenient in use and high in test efficiency. Various errors caused by human factors of testees and optometrists and instruments can be reduced when a shadow test, an automatic optometry unit and the like are used for optometry, so that the accuracy rate of detection is improved effectively.

The back surface of said housing is provided with tangent scale check table and diopter conversion table, and said tangent inspection graduation apparatus center is provided with a LED lamp, and the rear portion of said housing also is provided with the on and off switch of switch LED lamp.The patient aims at the back surface of housing and tests, and can estimate patient's diopter situation roughly, can also carry out the inspection of tangent scale, functional diversities after turning on the power switch.
Described main circuit board is provided with light barrier, prevents dazzlingly, and influence test is carried out.
Be provided with a tape measure in the described housing, described tape measure be provided with one be used to pull tape measure the tape measure button, this tape measure button exposes to loam cake, is used for accurately measuring measuring distance, and test accuracy is provided.
The rear portion of said housing is provided with battery and battery cover, and housing outer surface also is provided with the switching push button that switches polarization (red green) icon.
Also be provided with signal in the described housing and receive head, describedly closely also dispose an external remote controller with vision tester for eyesight.
Described remote controller is provided with the on and off switch and the polarization icon switching push button of control LED lamp switch.Can be directly on housing or the remote controller drilling do to accomplish the switching of polarization icon.
Described display plate component comprises printing PMMA plate, aluminium sheet, various red embolium, polaroid and parchamyn paper.
This utility model has been integrated multiple eye refractometer function commonly used, possesses multiple functions such as red green polarisation detects, the detection of myopia detection diopter, and the patient can directly hand and test, and is easy to use, and testing efficiency is high.Also can reduce when using skiametry and auto-refractomer etc. to carry out optometry anthropic factor and the caused multiple error of instrument itself, the accuracy rate of effective raising detection because of subject and optometrist.
