Method and device for detecting eyesight

The invention belongs to the field of communication and provides a method and device for detecting eyesight. The method for detecting eyesight comprises the steps that a main machine obtains the distance between the main machine and an auxiliary machine, the distance is worked out in the mode that the main machine and the auxiliary machine send detecting signals to each other and receive responding signals of the detecting signals from each other, and the main machine and the auxiliary machine are both devices provided with short distance wireless communication modules; the main machine provides an eyesight detection icon table corresponding to the distance between the main machine and the auxiliary machine through matching according to the distance between the main machine and the auxiliary machine; the main machine displays eyesight detecting icons in the eyesight detecting icon table corresponding to the distance between the main machine and the auxiliary machine; the main machine receives a result of identification of the eyesight detecting icons by a detected person, wherein the result of identification is sent by the auxiliary machine; the main machine obtains a detecting result according to the result of identification. According to the method and device for detecting eyesight, the size of each icon in the eyesight detecting icon table is automatically adjusted according to the different current distances between the main machine and the auxiliary machine, the influence of the environment is avoided, and user experience is greatly improved.
