Embodiment 1

[0042] This embodiment proposes an automated eyesight testing system, including: an eye chart light box and a mobile terminal, and the eye chart light box is connected to the mobile terminal through Bluetooth communication;

[0043] Specifically, such as figure 1 As shown, the eye chart light box includes an optotype panel 1 , a light insulation panel 2 , an LED lighting panel 3 , a battery 4 , a main board 5 and a back panel 6 . There are visual target groups on the visual target panel, and corresponding LED lights are arranged under each visual target, and the LED lights are located on the LED light panel. The main board and the battery are arranged on the LED light panel, and a digital tube display circuit is arranged between each LED light and the main board, and the battery supplies power for the LED light and the main board. In addition, the eye chart light box of the present invention further includes a bluetooth module for the bluetooth communication between the eye c...

Embodiment 2

[0051] The automated eyesight testing system in this embodiment includes, in addition to the eye chart light box and mobile terminal in Embodiment 1, a cloud server, which can be Alibaba Cloud, etc., and is not limited here. The cloud server is connected to the mobile terminal through mobile communication. Specifically, the mobile communication reports the tested vision level of the user to the cloud server for storage. The present invention can store and manage the eyesight level of the user by setting up the cloud server, discover the change of the eyesight of the user in time, and provide the user with corresponding eye sight protection suggestions.

[0052] The present invention manages the eyesight level of the user, and first needs to store the basic information of the user in the cloud server, for example, the user's name, class, student number, etc. In order to improve the speed of vision testing and manage the user's vision, personal identification can be determined b...

Embodiment 3

[0056] Such as figure 2 As shown, this embodiment proposes an automated vision testing method, which is applied to the above-mentioned automated vision testing system, and specifically, the mobile terminal in the testing system implements a specific application program. Specifically include:

[0057] S1. The optotype line corresponding to the default standard logarithmic vision is used as the current optotype line, and the correct number of tests n=0 and the number of wrong tests m=0 are set;

[0058] The visual target group of the present invention is a standard logarithmic visual acuity chart conforming to GB11533-2011, which is composed of fourteen levels of visual target lines, and the standard logarithmic visual acuity of the fourteen levels of visual target lines is 4.0 in turn , 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, 5.0, 5.1, 5.2, 5.3. Corresponding optotypes are set in each optotype row, and the size of the optotype gradually decreases from top to bottom in a...

Abstract

The invention discloses an automatic vision testing system and method. The system comprises a visual chart light box and a mobile terminal, wherein the visual chart light box is in communication connection with the mobile terminal through Bluetooth; the visual chart light box comprises a sighting mark panel, a light isolation plate, an LED light panel, a battery, a mainboard and a backboard; a sighting mark group is arranged on the sighting mark panel, and a corresponding LED lamp is arranged below each sighting mark; each sighting mark row in the sighting mark group is provided with a corresponding sighting mark, the size of the sighting mark is gradually reduced from top to bottom in a stepped mode, and the corresponding standard logarithm vision is gradually increased from top to bottom; and the mobile terminal transmits the selected sighting mark to the mainboard in the visual chart light box, and the mainboard controls the LED lamp corresponding to the sighting mark to be turned on. According to the invention, vision testing and corresponding data processing and judgment are carried out through the mobile terminal, so that hardware and software cost of the visual chart light box is greatly reduced; and meanwhile, vision testing is carried out in combination with voice, images and the like, so that the operation complexity is reduced.

Description

technical field [0001] The invention relates to the field of vision testing, in particular to an automatic vision testing system and method. Background technique [0002] At present, there are many standard logarithmic vision charts in the market that comply with GB11533-2011. The test method is still in accordance with the old manual test method. It is necessary for the tester to specify which visual mark to be identified by the testee. The test process does not have a standard process. There is no criterion for judging the results, and there is a lot of subjectivity. [0003] The publication number is CN 210009010U, which discloses a visual acuity tester and a visual acuity testing system based on the Internet of Things, including a visual acuity chart light box and a rocker. The visual acuity chart light box includes a visual acuity chart and a light box circuit, and the light box circuit is set at the position corresponding to the test symbol in the visual acuity chart ...
