Description
Technical field
The present invention relates to eye examination field, in particular to a kind of device that visual performance inspection is carried out using AR technology.
Background technique
Eyes are most important organs in human sensory, and about 80% knowledge and memory are all to pass through eyes in brain
It obtains, eyes are the most important modes for spatial orientation, emotion communication and study, therefore, in due course to eyes function
It is very necessary for can be carried out inspection.
The visual performance that people are recognized mainly includes strabismus, amblyopia, stereopsis, fusion function etc..Wherein, it squints
The visual problems such as amblyopia significantly impact the normal life of people.Traditional visual performance is tested can detect by synptophore,
Prism, which adds, covers detection, cornea optical reflection method etc. to carry out.However there is variety classes for existing visual function examination device
Defect: 1, every instrument has complicated operate with method, need professional to assess the eyes performance of patient,
If lacking the personnel of profession, patient usually oneself can not use apparatus measures；2, equipment instrument is larger, inconvenient to carry, and 3,
Some is higher to measurement required distance, and some inspection methods are affected by ambient light intensity etc..
With the development of augmented reality AR technology, AR technology has been obtained in medical field to be widely applied, AR glasses
It is easy to carry, using simple, the brightness of display device can be adjusted according to light conditions, can be more true, three-dimensional
The structure of model is shown, the visual performance that AR device is expected to become new checks equipment.
Summary of the invention
It is an object of the invention to overcome existing visual performance check equipment is inconvenient to carry, complicated for operation, condition require compared with
High defect provides a kind of AR spectacle visual function examination device by emerging augmented reality.
The present invention is achieved through the following technical solutions:
AR spectacle visual function examination device of the invention, including AR glasses 1 and mobile terminal 2, AR glasses include frame 3,
