Embodiment Construction

[0019] see figure 1 , the vision testing device of the present invention comprises a control module, a display module, a detection result processing module, a storage module, an input module, an alarm module (optional), an effective distance judgment module (optional), a distance detection module, and a distance-vision level database, Among them, the display module, the detection result processing module, the storage module, the input module, the alarm module, the effective distance judgment module, the distance detection module, the distance-sight level database and the control module are respectively connected.

[0020] The display module is used to display the symbol (can be "E" or "C"). The display method is different from the paper test form. It is not necessary to display all symbols, only one symbol is displayed at a time, and another symbol is displayed after the tester inputs the selection result.

[0021] The input module is used for receiving the selection result i...

Abstract

The invention relates to a vision tester, which comprises a control module, a display module, a test result processing module, a memory module, an input module, a distance detection module and a distance-vision grade database, wherein the control module is respectively connected with the display module, the test result processing module, the memory module, the input module, the distance detection module and the distance-vision grade database. The vision tester is highly portable, and cannot be limited by regions and time; a tester can independently carry out a vision test, and the vision tester is extremely convenient to operate; the interference of anthropic factors is prevented, and therefore the test result is accurate; and a test result and related advices can be obtained in time.

Description

【Technical field】 [0001] The invention relates to a vision testing device. 【Background technique】 [0002] When testing eyesight, generally all is to adopt the paper vision test form, this kind of vision test method can only be carried out with the assistance of others, and also has strict requirements on the venue (the distance from the vision test form must be a standard distance). [0003] Therefore, the traditional visual acuity test method is more complicated to operate, and the practicability is not strong. 【Content of invention】 [0004] In view of this, it is necessary to provide a vision testing device to solve the problems of complicated operations and poor practicability of the vision testing methods in the prior art. [0005] Technical scheme of the present invention is as follows: [0006] A vision testing device, comprising a control module, a display module, a detection result processing module, a storage module, an input module, a distance detection modul...
