Abstract

The invention provides a method and device for protecting the vision of a user and aims at reminding a user to keep a larger distance with a terminal screen so as to avoid eye injuries caused by a terminal screen. The method for protecting the vision of the user comprises the steps that distance information between the head of the user and the terminal screen is determined; whether the distance information is smaller than or equal to a preset distance threshold value or not is judged, if yes, reminding information is displayed and / or the brightness of the terminal screen is displayed, and timing begins, wherein the reminding information is used for reminding the user to increase the distance away from the terminal screen; continuous duration when the distance information is smaller than orequal to the preset distance threshold value is calculated, and if the continuous duration is greater than or equal to a preset time threshold value, the preset duration of the terminal screen is closed.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method and device for protecting user eyesight. Background technique [0002] In the era of networking, electronic devices have become a necessity for adults or minors, and almost everyone has a mobile phone, a computer or a tablet. However, facing the screen of electronic equipment for a long time will cause visual fatigue and even vision loss of the user. Watching the screens of electronic devices such as mobile phones, tablet computers or computers at close range has a serious impact on the vision of children or adolescents during development. [0003] Therefore, how to remind the user to keep a relatively large distance from the terminal screen to avoid eye damage from the terminal screen is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] The present invention provides a method and device for protecting the user's ...
