Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the related art, the eyesight can be prevented and corrected by wearing glasses with the functions of prevention, treatment and correction, for example, the glasses for preventing myopia remind a user of unreasonable eye using state by giving out alarm sound or giving out light flickering, but the reminding mode is not a forced reminding mode and cannot achieve the purpose of effective reminding. For example, the lenses are made of dimming glass, the transparency degree can be changed under the control of the controller, and the lenses are changed from the transparent state to the non-transparent state under the condition that the preset condition is met, so that a user is reminded to rest or adjust the posture, but the glasses with the structure have large power consumption, cannot be used for a long time, and are inconvenient to maintain; meanwhile, the smaller measurement range causes more limitation conditions and inconvenience in use.

Figure 1 is a schematic diagram illustrating a configuration of vision protection eyewear according to an exemplary embodiment, such as the vision protection eyewear shown in figure 1, comprising: the variable color lens 10, the bearing component 20, the distance measuring sensor 30 and the control module 40.

The color-changeable lens 10 is connected with the bearing component 20, electrically connected with the control module 40, and used for controlling the light transmittance through the electrical signal input by the control module 40.

The distance measuring sensor 30 is rotatably connected with the bearing component 20 or the control module 40, and is electrically connected with the control module 40, and the measuring surface faces to the direction faced by the color-changeable lens 10 for measuring the distance.

The control module 40 is detachably connected to the bearing assembly 20, and is configured to output the electrical signal to the variable color lens 10 according to the measured distance sent by the distance measuring sensor 30.

In this embodiment, the carrier assembly 20 is used to mount the variable color lens 10, the ranging sensor 30, and the control module 40. The color changeable lens 10 is fixedly connected with the bearing component 20 and electrically connected with the control module 40, and the light transmittance of the color changeable lens 10 can be changed under the control of different voltages or currents, so that the color changeable lens is changed from a transparent state to a non-transparent state. The distance measuring sensor 30 is rotatably connected with the bearing component 20 or the control module 40, and the distance measuring sensor 30 is used for measuring the distance from a to-be-observed object (reading object or watching object) in front of the sight line. The control module 40 is detachably connected to the carrier assembly 20, and after the control module 40 receives the measured distance sent by the distance measuring sensor 30, the current or voltage is output to the variable color lens 10 to control the variable color lens 10 to be in a transparent state or a non-transparent state. In this embodiment, the control module 40 is interactively connected to the distance measuring sensor 30, and the output end of the control module 40 is connected to the input end of the color-changeable lens 10. The color-changeable lens 10 includes two sub-lenses, and the sub-lenses may be electrochromic glass or liquid crystal dimming glass.

For example, a preset distance threshold value is prestored in the control module 40, and when the distance measured by the range sensor 30 is less than the preset distance threshold value, it may be considered that myopia may be caused, and when the distance measured by the range sensor 30 is greater than the preset distance threshold value, it may be considered that hyperopia may be caused. The color changing process of the color changeable lens 10 is as follows: the control module 40 controls the distance measuring sensor 30 to measure the distance, the distance measuring sensor 30 sends the measured actual distance to the control module 40, the control module 40 compares the actual distance with a preset distance, and when the actual distance is greater than or less than a preset distance threshold, the control module 40 outputs current or voltage to the variable color lens 10 to control the variable color lens 10 to change from a transparent state to a non-transparent state; then, the control module 40 controls the distance measuring sensor 30 to measure the distance, the distance measuring sensor 30 sends the measured actual distance to the control module 40, the control module 40 compares the actual distance with a preset distance threshold, and when the actual distance is within the preset distance threshold, the control module 40 outputs current or voltage to the variable color lens 10 to control the variable color lens 10 to change from the non-transparent state to the transparent state.

In such a scenario, the sight protecting glasses may prevent the user from using the eyes for a long time within an unreasonable distance to remind the user that they need to use the eyes within a reasonable distance to avoid developing poor eye habits that lead to myopia or hyperopia. The preset distance threshold and the preset duration can be set according to needs.

In this embodiment, the user is reminded to change the eye using distance from the transparent state to the non-transparent state through the color-changeable lens 10 so as to avoid using eyes in an unreasonable distance, and the user is reminded to avoid using eyes unreasonable for a long time, so as to be reminded to relax and relieve asthenopia. The glasses can not be used continuously for reading and watching under the condition that reasonable eye using conditions are not met after the lenses are changed into the non-transparent state, so that the user can be reminded effectively.
