Description

A method and device for reminding users to protect eyesight

technical field

Embodiments of the present invention relate to the technical field of mobile terminals, and in particular to a method and device for reminding users to protect eyesight.

Background technique

Blinking is usually divided into two types, one is involuntary blinking movement; the other is reflex eye-closing movement. Involuntary eye blinking, except for inflammation and pain stimulation, usually has no external stimuli, and is completed unconsciously by people. According to statistics, normal people blink more than ten times per minute on average, usually every 2 to 6 seconds, and each blink takes 0.2 to 0.4 seconds. Involuntary blinking is actually a protective action, which can evenly distribute tears on the cornea and conjunctiva to keep the cornea and conjunctiva moist. Blinking can also temporarily rest the retina and eye muscles.

Children tend to be too fascinated when using devices such as tablets, and do not pay attention to eye posture and eye habits. Current view protection only protects vision by distance.
