Description
Technical field
The present invention relates to a kind of therapeutic instrument for shortsightedness, more specifically, it relates to a kind of VR children's visions correction based on DLP
Instrument.
Background technology
With the development of science and technology, have increasing A nearsighted person in society, life, study and work that myopia gives people
Bring very big inconvenience.At present, for convenience, most of A nearsighted persons are equipped with and are adapted to usually after it have detected myopic degree
The glasses of oneself, to facilitate study, live and work.But, long-term use glasses, can cause A nearsighted person to glasses according to
Rely property increasing, it is ordinary affair for the A nearsighted person that wears glasses to look for glasses everywhere when getting up, to life bring it is very big not
Just, and in the case where the unexpected loss of glasses occur or damaging A nearsighted person can not normally live or work completely,
There is situation about can't take care of oneself in severe patient.Myopia laser surgey is also occurred in that at present, is mainly passed through with PRK
Hypothallus carries out phototropism cutting under corneal valve, so as to reduce the corneal curvature of lesser ring of Merkel, reaches the purpose of myopia correction, but
It is operation or dangerous property, is also unable to estimate for the sequelae after the patient's age for carrying out myopia laser surgey.
There is a kind of therapeutic instrument for shortsightedness based on VR helmet shape-designings on the market at present, show far and near continuous on a display screen
The target of change, the crystalline lens for allowing user to watch the target of focal length variations attentively to force eyes follows change, to reach exercise eye
The purpose of eyeball ciliary muscle, so as to play treatment or alleviate the effect of myopia.This therapeutic instrument for shortsightedness, is using LCD or OLED
Display Technique, the shortcoming of this Display Technique is that to project image in human eye be real image, after user watches attentively for a long time, eye meeting
Injured by certain, do not reach expected rectification effect.
Further, since because the time of myopia is more long, and user is generally the children of below 12 one full year of life, holds very much
Easily fall asleep over the course for the treatment of；Because correcting instrument is to tie up head in user by fixing band, and inner side is pressed in user
Eye locations, can to a certain extent influence user's circumference of eyes tissue blood circulation；And user is after sleeping, meeting
This influence being subject to for a long time, being very likely to cause eye fatigue because blood circulation is obstructed, influence eye is good for
Health.
The content of the invention
In view of the shortcomings of the prior art, rectified it is an object of the invention to provide a kind of VR children's visions based on DLP
