Abstract

The invention relates to a near sight prevention system, comprising an image pick-up unit, a face identification unit, a driving unit, a conversion unit and a comparison unit, wherein the driving unit is used for the focus adjustment of a face driving image pick-up unit of the face identification unit; when the focus adjustment of a face is carried out by the driving unit, the conversion unit can record the walking steps of the driving unit, and converts the walking steps into actual distances between the face and the image pick-up unit; a standard distance range is prearranged in the comparison unit, and the actual distances are compared with the prearranged standard distance range by the comparison unit; and in the premise that at least one actual distance of the converted distances does not included in the standard distance range, the comparison unit sends out a trigging signal to an alarm unit so as to result in the alarm unit to alarm. The near sight prevention system of the invention can give an alarm to prompt a user when the viewing distance thereof is excessively short.

Description

technical field [0001] The invention relates to a myopia protection system. Background technique [0002] In people's daily life, eyes are the most important organ for receiving external information. With the development of the economy and the acceleration of the pace of life, people's average daily eye use intensity has increased significantly. There are many reasons for myopia, among which the most important reason is to use the eyes at close range for a long time. For example, the distance of watching TV should be 5-6 times of the diagonal length of the screen. If it is less than this distance for a long time, it is easier to produce myopia. [0003] However, the prior art does not have a myopia protection system that can send an alarm when the user watches the screen at a close distance. Contents of the invention [0004] In view of this, it is necessary to provide a myopia protection system that can issue an alarm in time when the viewing distance is too small. ...
