Embodiment Construction
[0038] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .
[0039] Such as Figure 1-2 As shown, the vision detection method provided by the embodiment of the present invention is applied to a vision detection device. The vision detection device includes a light-transmitting plate 1, a number of vision-testing marks 2 arranged on one side of the light-transmitting plate 1, and a plurality of eyesight detecting marks 2 arranged on the other side of the light-transmitting plate 1. The side is used to provide several light emitting units 3 for providing light sources for the vision detection sign 2 . Wherein, the arrangement of vision detection signs 2 can be as follows figure 1 As shown, it can also be arranged...

The invention discloses an eyesight detecting method and device. The eyesight detecting method can be applied to the eyesight detecting device, the eyesight detecting device comprises a light-transmitting plate, a plurality of eyesight detecting identifications arranged on one side of the light-transmitting plate, and a plurality of light-emitting units arranged on the other side of the light-transmitting plate and used for providing a light source for the eyesight detecting identifications; and the eyesight detecting method comprises the steps that an eyesight detecting command is obtained; one of the light-emitting units is controlled to emit light according to the eyesight detecting command, and thus the corresponding eyesight detecting identification is highlighted; user response information is obtained; and eyesight detecting results are output according to the user response information and the highlighted eyesight detecting identification. According to the eyesight detecting method, eyesight detecting can be completed without guidance of a specially-assigned person, and eyesight detecting information can be obtained in real time by a user.
Description
technical field [0001] The invention relates to the field of vision detection, in particular to a vision detection method and device. Background technique [0002] The eyeball is one of the most fragile organs of the human body, especially in the current era of information explosion and Internet + era, the human eye is facing a great impact. There are many kinds of eye diseases and complex, and once suffering from eye diseases, it is difficult to cure, but before the outbreak of eye diseases, there will be warning signs. Therefore, the timely detection and dynamic observation of eye vision are of great significance to the prevention and control of eye diseases. [0003] At present, the main method of visual acuity testing is still the traditional eye chart. The eye charts used in China include international standard eye chart, logarithmic eye chart, Langer’s surround vision eye chart, and some LED light box eye charts. However, these vision charts are faced with a problem,...
