The vision protection apparatus 100 according to an embodiment of the present invention may be implemented by a fewer components than the components shown in FIG. 2, or may be implemented by fewer components. Hereinafter, the above-mentioned constituent elements will be described in detail.

The sensor unit 110 can detect a person appearing in front of the television 200. For this purpose, the sensor unit 110 may be implemented by a variety of known sensors capable of sensing a person, for example, an infrared sensor.

In addition, the sensor unit 110 may include a sensor cap and a variable resistor so that only a person present in a predetermined dangerous section among the people appearing in front of the television 200 can be detected. Referring to FIG. 3, the dangerous period refers to a position where the possibility of visual deterioration is likely to occur when the television 200 is viewed at the corresponding position, and may be set by the user and stored in the memory unit 160. For example, the danger zone may be set to a fan shape having a central angle of 100 degrees and a maximum danger radius of 2 m based on the center point of the television 200. Therefore, the sensor unit 110 can limit the sensing angle using the sensor cap so that only the person within the predetermined danger zone can be detected, and adjust the sensing distance using the variable resistance.

When the detected person watches the television 200 The controller 130 may calculate the number of steps required to move the television 200 to an appropriate position and output the output through the output unit 140 or turn off the power of the television 200. For this purpose, And a step calculating unit 132. [

Specifically, the controller 130 may determine whether a person exists within a danger zone for a first predetermined time after a person existing in the danger zone is detected by the sensor unit 110. The control unit 130 may receive a signal including the information from the sensor unit 110 when a person appears within the danger zone. At this time, the control unit 130 may receive a signal It is possible to measure the duration and determine how long the detected person is within the danger zone within the danger zone according to the measured reception duration.

Here, referring to FIG. 3, the safe interval means a proper viewing position of the television 200 that is unlikely to cause a problem of visual loss even if the user views the television 200 at the corresponding position. 160 in advance. For example, the safety interval may have the same central angle as the danger zone and may refer to the interval between the minimum safety radius of 2m and the maximum safety radius of 3m. That is, in a fan-shaped form having a central angle of 100 degrees and a maximum danger radius of 3 meters as a radius on the basis of the center point of the television 200, except for a dangerous section having a central angle of 100 degrees and a sector shape having a radius of 2 meters, It can mean a section.
