Example Embodiment

[0037] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0038] Reference figure 1 , figure 1 It is a flowchart of the first embodiment of a method for protecting eyesight of the present invention. Such as figure 1 As shown, the process includes the following steps:

[0039] Step S01, the preset time period, the viewer who is closest to the screen is detected once in each time period, and the viewing distance of the viewer is obtained; in the embodiment of the present invention, the position sensing device is set to The viewer who is closest to the screen is detected once, and the viewing distance of the viewer is obtained. In a specific embodiment, the preset time can be 0, that is, continuous detection; or another time period, such as 5 minutes, 10 minutes, or 30 minutes, etc. Any time period to detect once; the preset time period can be set at intervals , Such as cont...

Abstract

The invention discloses a method for protecting eyesight. The method comprises the following steps: presetting a time period; detecting an audience who is the most close to the screen once in each time period, and acquiring the viewing distance of the audience; determining whether the viewing distance is smaller than the preset value; when the viewing distance is smaller than the preset value, generating a first reminding information indicating that the viewing distance is too small, until the audience moves out of the area of the preset value. According to the invention, only the viewing distance of the audience who is the most close to the screen is acquired, such that whether the audience viewing distance satisfy the requirement of a scientific viewing distance can be rapidly determined; it is not necessary to acquire a viewing distance of every audience, such that working load of corresponding hardware is reduced. When the viewing distance of the audience is smaller than the preset value, the first reminding information is generated for indicating the audience that the viewing distance is too small. The audience adjusts the viewing distance according to the first reminding information, such that a requirement of scientific and healthy viewing of TV program can be satisfied, and audience health is prevented from being influenced by a small viewing distance.

Description

technical field [0001] The invention relates to the field of screen display, in particular to a method for protecting eyesight. Background technique [0002] With the replacement of TV sets, the screen size of TV sets has become larger and larger. However, after the TV screens have changed from small to large, the audience's viewing habits (such as viewing distance, display brightness and display color temperature, etc.) have not changed. But to watch TV programs in a healthy and scientific way, it is necessary to adjust the viewing distance and viewing time of the audience according to the brightness and radiation of different TV sets. The TV sets in the prior art do not have the function of reminding viewers to watch TV programs sparingly and scientifically, which causes a lot of viewers to suffer from vision loss due to long-time and close-up viewing of TV programs, and symptoms such as headache and eye irritation. Contents of the invention [0003] The main purpose of...
