Real-time zooming intelligent glasses based on viewpoint positioning technology

Abstract

The invention discloses real-time zooming intelligent glasses based on a viewpoint positioning technology. The intelligent glasses comprise a glasses main body, lenses, a power supply device and a zooming control part, wherein two lenses of the intelligent glasses are liquid crystal zoom lenses, and the zooming control part comprises a central processing driving module, a viewpoint positioning device, an image acquisition mini lens and a zoom driving module. The zooming degree of the liquid crystal lenses can be adjusted in real time according to the eye use condition of a user, it is guaranteed that the lenses are just in the lowest degree needed for clear view, it is guaranteed that the eyes are always in the relaxed state of long-distance vision, and vision recovery and correction can be induced by adjusting the initial degree to enable the eyes to be in the micro under-correction state. The whole appearance of the glasses is consistent with that of traditional glasses, the eyesightcan be improved under the condition that normal eye use is not influenced, the glasses are suitable for people with myopia and hyperopia, people with normal eyesight can avoid asthenopia through wearing the glasses, and myopia is prevented.

Description

technical field [0001] The invention relates to the field of smart wearable devices, in particular to a real-time zoom smart glasses for alleviating eye fatigue and restoring and correcting eyesight. Background technique [0002] With the popularity of electronic products and heavy work and study pressure, the incidence of myopia in my country ranks first in the world. "Pseudo-myopia" can be corrected and restored by improving eye habits and appropriate training, but "true myopia" has a longer axial axis and cannot be restored to normal by improving eye habits and vision training, and can only rely on wearing myopia glasses way of vision correction. Usually the glasses are equipped with the same degree of vision, regardless of distance, wearing glasses of the same degree will cause "overcorrection" when seeing things at close range, resulting in excessive adjustment of the eyes, spasm of ciliary muscle adjustment, and elongation of the eye axis. Increased myopia. In respo...

Problems solved by technology

"Pseudo-myopia" can be corrected and restored by improving eye habits and appropriate training, but "true myopia" has a longer axial axis and cannot be restored to normal by improving eye habits and vision training, and can only rely on wearing myopia glasses vision correction

Usually the glasses are equipped with the same degree of vision, regardless of distance, wearing glasses of the same degree will cause "overcorrection" when seeing things at close range, resulting in excessive adjustment of the eyes, spasm of ciliary muscle adjustment, and elongation of the eye axis. increased myopia

In response to this problem, the invention patent with the notification number CN104520756A discloses a "progressive multi-focal spectacle lens". The problem is that the zoom mode of the lens is fixed, and "overcorrection" will still occur when viewing objects at close range. Switching back and forth between different powers will cause eye swelling and dizziness. If things go on like this, it will cause visual fatigue and accelerate the growth of myopia

The invention patent with the notification number CN108524210A discloses a kind of "intelligent zoom glasses and its working method", which drives the lens to move back and forth through mechanical structures such as motors and leadscrews to realize lens zooming, but the problem is that the driving part adopts complicated Mechanical structure, low zoom precision, high power consumption, and prone to failure. The zoom glasses can only set the correction scheme according to fixed parameters, and cannot realize real-time automatic zoom. At the same time, the zoom glasses have a bulky appearance and can only be corrected for training at a specific time , can not be worn for a long time, which is also the problem of all current zoom glasses
