[0002] The eye is an important organ of human beings, and through the eye people can see the beautiful things in the outside world. However, with the increasing pressure of people's learning, work and life, the vision is seriously damaged. In this case, the vision examination is very important. If the problem is found, the eye can be intervened and protected in advance. The vision examination method usually has the following two kinds: (1) vision chart, which is divided into far vision chart and near vision chart. The far vision chart is usually given by the hospital, that is, the E-shaped vision chart at a distance of 5 meters. When the vision measured by the vision chart is poor, less than 1.0, the near vision chart can be measured. The distance of the near vision chart is usually 30 cm. If 1.0 can be read out, it means that the far vision is a problem, and the near vision is good. In other words, it is nearsightedness. If the far vision chart is good and the near vision chart is poor, it means that the far vision or presbyopia is a problem; (2) optometry. The computer optometry instrument can measure the degree of normal adults, and the degree of related lenses can be tried on to improve the vision. The refractive state of the patient can be measured more accurately. However, the existing vision examination needs the cooperation of the vision examination personnel, which is time-consuming and laborious, and the examination efficiency is not high, which wastes resources and reduces the accuracy of the examination results to some extent.

5. An intelligent eyewear interaction system, characterized in that, It comprises: The projector, the voice interactor, the glasses, the receiver, the terminal, the power supply and the player; The glasses are provided with a voice interactor, a receiver and a player; The voice interactor is wired connected with the projector, the receiver and the player; the power supply is connected with the projector, the voice interactor, the glasses, the receiver and the player; and the voice interactor is wirelessly connected with the terminal; The process of light compensation of the projector includes: Starting the light compensation module under the control of the projector; The light compensation module feeds back the light intensity to the projector through the light sensor; the projector judges the light intensity; if the light intensity reaches the preset light threshold, the projection continues; if the light intensity does not reach the preset light threshold, the light compensation is performed; The projector filters the character image to be projected, and retains the edge information of the characters of the visual acuity chart; The filter model used by the projector for filtering the character image is: ； ； wherein, represents a gray value of a character image before filtering at coordinates , represents a gray value of a character image after filtering at coordinates , r represents a window radius of a filter, represents a set of coordinates of pixels in a square region centered at with a side length of (2r+1), represents a gray similarity weight at coordinates , and respectively represent a spatial standard deviation and a gray standard deviation; The process of recognition of the voice interactor includes: The voice interactor receives the voice feedback of the characters of the visual acuity chart by the examinee; The voice interactor compares the feedback voice with the opening direction of the pre-stored characters; When the error rate exceeds the first preset threshold, the characters of the visual acuity chart are automatically moved up one line; When the accuracy rate of the feedback voice reaches the second preset threshold, the visual acuity result of the examinee is recorded; When the error rate exceeds the first preset threshold, the visual acuity chart starts to let the examinee read the characters of the previous line; if the error rate still exceeds the first preset threshold, the moving up continues until the top line of the visual acuity chart is reached; when the accuracy rate reaches the second preset threshold, the line where the characters are located is the visual acuity value of the examinee, and the visual acuity value is displayed.

6. The smart glasses interaction system of claim 5, wherein, The player is provided with a sound sensor and an audio current adjusting module; the sound sensor is connected with the audio current adjusting module.

7. The smart glasses interaction system of claim 5, wherein, The projector is provided with a light compensation module, a light sensor and a filter; The light compensation module is connected with the light sensor and the filter.
