Abstract

The invention discloses an eyesight protection device comprising a distance sensor, a mode selecting unit and a processor, wherein the mode selecting unit is used for selecting the working mode of the eyesight protection device. The eyesight protection device is characterized in that the distance sensor senses the distance between a user and a display and sends a distance signal; and the processor compares the distance signal with a preset value and correspondingly sends an alarm signal according to the comparison result and the selected operating mode so as to prompt that the user and the display are too close. The invention also discloses an eyesight protection method.

Description

technical field [0001] The invention relates to a vision protection device and method. Background technique [0002] The existing displays generally do not have the function of protecting the user's eyesight.
