The light brightness measuring unit 52 includes a brightness sensor (or a light sensor and related circuits) installed at the ambient brightness detection window 154 of the case 1, and is used for detecting the ambient brightness near the head or body of the user and transmitting the detection signal to the processing unit 51; and a brightness sensor (a luminance-type sensor with an imaging system, for example, a camera or a photosensor and related circuits) provided at the detected-brightness detection window 152 of the case 1 for measuring an object to be viewed, such as: a display screen such as a television, a computer, an IPAD, a mobile phone, or a projection screen, which is capable of emitting light and displaying a specific graphic information page, the brightness of the display screen on or near the display screen (i.e., the brightness reflected in a specific area on the display screen surface watched by the user due to the emission of the object to be viewed), and transmits the detection signal to the processing unit 51. The processing unit 51 compares the brightness of the viewed image with the ambient brightness, such as: difference or fold value; the processing unit 51 judges that, if the comparison result exceeds the medically recommended value, for example: a high value above the prescribed range or a low value below the prescribed range indicates that it is necessary for the sight protecting alert box 10 to emit an alert sound to alert the user that the viewing brightness is not appropriate.
It should be noted that the processing unit 51 can determine whether an alarm is required according to the brightness of the subject. That is, the processing unit 51 may obtain a judgment that the absolute value of the viewed brightness is too dark or too bright according to the absolute value of the viewed brightness (ignoring the ambient brightness) when the absolute value of the viewed brightness exceeds a preset range, and then generate a reminding sound to remind the user that the viewing brightness is not appropriate.
It is to be understood that, although the foregoing description has been made by taking the viewed object as a display screen capable of emitting light, in other application cases, the viewed object may be a display screen which does not emit light, and the viewed object may also be an object which does not emit light, such as a book or a newspaper.

The processing unit 51 judges that if this distance exceeds the medically suggested value, for example: a high value above the prescribed range or a low value below the prescribed range indicates that it is necessary for the sight protecting alert box 10 to emit an alert sound to alert the user that the viewing distance is not appropriate.
The line-of-sight distance alarm setting unit 55 includes a plurality of keys and related circuits mounted at the line-of-sight distance alarm setting operation window 166 of the box body 1; and a display circuit provided at the line-of-sight distance alarm setting display window 156 of the box body 1 for the user to set the line-of-sight distance alarm condition.
