Watch content to be displayed；With that is, user transfers to watch display screen at a distance, display screen will be focused display, in this way, user
Content to be displayed can be clearly watched, the purpose that guidance user keeps reasonable distance to be watched is realized.
In of the invention one optionally embodiment, with reference to Fig. 3, the myopia prevention device further include: voice prompting device 13,
Voice prompting device 13 is set on electronic display unit 1, and voice prompting device 13 is connect with controller 12；
Wherein, when controller 12 determines the display screen for obtaining user and being just look at electronic display unit 1, and the eyes of user
With when being less than pre-determined distance at a distance from display screen, control voice prompting device 13 prompts user, so that user is far from display
Screen.
In order to better pre- myopia prevention, inventor is provided with timer 14 on the myopia prevention device, with reference to Fig. 3,
Timer 14 is set on electronic display unit 1, and timer 14 is connect with controller 12；
Wherein, when controller 12 determines that obtaining user is just being look at the display screen of electronic display unit 1, timer is controlled
14 carry out timing, and the duration that timer 14 is counted is sent to controller 12, so that controller 12 controls language according to duration
Sound prompting device 13 prompts user to rest.
Specifically, after controller 12 receives the duration of the transmission of timer 14, if duration is greater than preset duration, control
Device 12 controls voice prompting device 13 and user is prompted to rest.
When inventor considers that user uses electronic display unit 1, myopia is generated in addition to closely watching display with user
Shield related, the display brightness that may also display screen is related.For this purpose, inventor is provided with light sensor 15 on myopia prevention device,
With reference to Fig. 4, light sensor 15 is set on electronic display unit 1, and light sensor 15 is connect with controller 12；
Light sensor 15 is used to incude the light intensity of 1 local environment of electronic display unit, and light intensity is sent
To controller 12；
