Remotely-controlled visual chart (capable of treating amblyopia and low myopia) with box

Abstract

The invention discloses a remotely-controlled visual chart (capable of treating amblyopia and low myopia) with a box, which is characterized in that detection symbols refer to eight openings (upper, lower, left, right, upper-left, lower-left, upper-right and lower-right), eight ensiform remotely-controlled receiving type indicating lamps (at upper, lower, left, right, upper-left, lower-left, upper-right and lower-right) are arranged above a box body, the indicating lamps have eight colors, a remotely-controlled transmitting pedal (divided into upper, lower, left, right, upper-left, lower-left, upper-right and lower-right parts) is correspondingly arranged, the pedal has corresponding eight colors, and the center of the remotely-controlled pedal is provided with a device which can carry out 360-degree rotation. The top of the box body is provided with an inserting slot for replacing visual charts, and 3-5 pieces of symbol vision boards with different detection directions are stored. The remotely-controlled visual chart (capable of treating the amblyopia and the low myopia) with the box can be used for carrying out the ordinary vision detection, and also can carry out the normal vision detection on deaf-mute children, and in the process of vision detection, a tested person is not required to talk but just steps on corresponding arrows while seeing the opening directions or colors of the detection symbols of the visual chart, then the indicating lamps above the visual chart are turned on, so that through cooperating with a vision correction method (application number: 201110270610. X) invented by the inventor of the invention previously, a person with the amblyopia and the low myopia can achieve or are close to be at a condition of normal vision in a short time.

Description

technical field [0001] The invention belongs to an eye chart used in ophthalmology. Background technique [0002] Ordinary eye charts used in ophthalmology have fixed detection symbols and few directions of detection symbols. Some people will memorize the opening direction of the detection symbols on the eye chart in advance, or memorize them after one or two tests. Can recite smoothly but cannot detect the real vision level, and deaf-mute children cannot do normal vision tests because they cannot speak, so they come up with the idea of ​​increasing the opening direction of the detection symbols, replacing different detection boards and adding remote control pedals Methods. It can be used as an ordinary eye chart, and it can also be used for vision testing of deaf-mute children. It can maximize the accuracy of vision testing, reduce the labor intensity of medical staff, and improve work efficiency. It is especially suitable for the general survey and testing of a large numb...
