The present invention relates to an eye glasses for eye protection, and more particularly, to an eye glasses for eye protection equipped with a TN-type, STN-type polymer dispersed liquid crystal lens that is divided into multiple areas and individually controlled light transmittance.

As imaging science advances due to the development of industrial technology, the development of lenses used for glasses to protect the eyes is increasing. Conventionally, the lens for each characteristic is overlapped to control the transmittance by changing the incident angle of light of the lens.

For example, sunglasses are used to protect the eyes from excessive exposure to natural light.However, since a certain amount of light is transmitted regardless of the amount of natural light, the amount of natural light varies depending on the location or location. You cannot adjust it properly.

In order to solve this problem, a type of sunglasses in which glass grains are blackened in accordance with the transmission intensity of ultraviolet rays has been researched and developed.

In addition, the sunglasses have a problem that it is difficult to determine the situation or to grasp the environment when the headlight is strongly incident when the headlight is strongly incident during the night driving, due to the instantaneous glare.

It is to be noted that the same components of the drawings are denoted by the same reference numerals and symbols as possible even if they are shown in different drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Also, when an element is referred to as "comprising ", it means that it can include other elements as well, without departing from the other elements unless specifically stated otherwise.

1 is a perspective view showing an eye protection electronic glasses according to the present invention, Figure 2 is a schematic configuration diagram showing an eye protection electronic glasses according to the present invention.

As shown in FIGS. 1 and 2, the electronic glasses for protecting eyesight according to the present invention include a selection button 11, an illuminance sensor 12, 13, a control unit 14, a liquid crystal lens driving circuit unit 15, and a liquid crystal lens. (16) (17), frame (18), and battery (21).

The selection button 11 is configured in the frame 18 or the leg 19, 20 is a button that can set the light transmittance adjustment mode of the electronic glasses.

The light transmittance adjustment mode of the electronic glasses that can be set by the selection button 11 is a mode for adjusting the light transmittance of the liquid crystal lenses 16 and 17 up and down, and the light transmittance of the liquid crystal lenses 16 and 17. Examples include a mode for adjusting left and right and a mode for intensively increasing light transmittance at the center of the liquid crystal lenses 16 and 17.

The illuminance sensors 12 and 13 are sensors for detecting the intensity and direction of light and may be installed on the top and bottom or left and right of the frame 18.

That is, when the adjustment mode for adjusting the light transmittance of the electronic glasses up and down by the selection button 11 is set, the controller 14 transmits the light transmittance based on the illuminance signal input from the illumination sensor located above and below the frame 18. If the control mode is set to control the light transmittance of the electronic glasses to the left and right by the selection button 11, the control unit 14 based on the illumination signal input from the illumination sensor located on the left and right of the frame 18. Control the light transmittance.

Of course, the control unit 11 in the mode that can intensively increase the light transmittance of the central portion of the liquid crystal lens 16, 17, the liquid crystal lens 16 (17) according to the illuminance sensed by the illumination sensor 12 (13) Control the light transmittance.

The control unit 14 for adjusting the light transmittance according to the intensity and direction of light detected by the light intensity sensor 12, 13 in the light transmittance adjustment mode set to the specific mode as described above by the selection button 11 Output a control signal.

Herein, the battery 21 is supplied to the liquid crystal lenses 16 and 17 through the liquid crystal lens driving circuit unit 15 under the control of the controller 14.
