Vision test prompting method and wearable equipment

Abstract

The invention provides a vision test prompting method and wearable equipment. A sighting mark corresponding to a preset vision level is output and displayed in a screen of the wearable equipment; since the preset vision level, the ideal distance and the size of the sighting mark have the corresponding relationship, the ideal distance is determined based on the preset vision level, and the practical distance between a user and the screen is tested; and when the practical distance is inconsistent with the ideal distance, prompt information is output to require the user to adjust the distance, so that the independent vision test without the help of others can be realized. The distance of the user can be adjusted according to the relationship between the practical distance and the ideal distance, and the sight distance between the sight of the user and a depth-of-field camera of the wearable equipment can also be adjusted, so that the vision testing accuracy is further improved.

Description

technical field [0001] The invention relates to the technical field of vision testing, in particular to a vision testing prompt method and a wearable device. Background technique [0002] At present, the myopia rate of Chinese teenagers is increasing day by day. In 2018, the myopia rate in primary schools reached 36.0%, that in junior high schools reached 71.6%, and that in high schools reached 81.0%. These are concerns for Chinese youth. From a technical point of view, the deterioration of vision of many teenagers is due to the gradual change of not paying attention to eye hygiene, and the school's vision test is usually done every six months, and it is too late to detect the problem. In order for teenagers to develop good eye habits, daily testing and tracking of vision changes can undoubtedly greatly strengthen the protection of teenagers' vision. It is against this background that the vision protection bracelet was proposed, through rapid quantitative evaluation and su...

Problems solved by technology

[0003] Traditional vision testing methods usually use international standard vision charts and testers, but these two vision test methods must be tested with the cooperation of other people, and vision tests cannot be completed independently, and the standard vision charts and testers are bulky and inconvenient Carry it around, causing some troubles for people to test their eyesight frequently
