Problems solved by technology

Under normal conditions, it is necessary to blink 15-20 times per minute on average so that the tear film is normally distributed on the surface of the eyeball, to protect the cornea, and to avoid damage caused by drying the surface of the eyeball. However, when teenagers are playing games or watching movies, usually Because of being too fascinated, you will forget to blink, which will damage your eyesight and lead to lifelong regrets

Abstract

The invention discloses an eye usage state detection method and an eye usage state detection device. The method includes controlling an infrared emitter to emit infrared rays to eye reflection areas of a user; counting the frequency of an infrared receiver for receiving the infrared rays reflected by eyelids in a first time slot, wherein the infrared emitter and the infrared receiver are arranged on a support of a spectacle frame; if the frequency of the infrared receiver for receiving the infrared rays reflected by the eyelids in the first time slot is smaller than a frequency threshold, reminding the user of short-time eyestrain. By the method, the eye usage state of the user can be detected to remind the user of eyesight protection.

Description

technical field [0001] The present application relates to the field of eyeglasses, in particular to a method and device for detecting eye states. Background technique [0002] Myopia is a common disease among teenagers, and the occurrence of myopia is usually related to improper use of eyes. Under normal conditions, it is necessary to blink 15-20 times per minute on average so that the tear film is normally distributed on the surface of the eyeball, to protect the cornea, and to avoid damage caused by drying the surface of the eyeball. However, when teenagers are playing games or watching movies, usually Because of being too fascinated, you will forget to blink, which will damage your eyesight and lead to lifelong regrets. Contents of the invention [0003] The main technical problem to be solved by this application is to provide a method and device for detecting the state of the eye, which can detect the state of the user's eye and remind the user to protect their eyesig...
