Abstract
The invention relates to a full-automatic comprehensive optometry unit. A conventional comprehensive optometry unit has long optometry period, a patient needs several rests during the period, and constant communication between an optometrist and a patient is required. Since the optometry period cost more time and has a certain subjectivity, the optometric result has a poor accuracy. The full-automatic comprehensive optometry unit comprises a hardware part and a software part, and is characterized in that the hardware part comprises an assembled lens, a visual chart, an infrared measurement light source, a collimation lens, a spectroscope, a reflector, a reticle and a measurement CCD; the software part comprises a control module and a calculation module; an infrared light emitted from the infrared measurement light source is projected to form a parallel beam through the collimation lens; the beam is reflected in the retina, goes through the reticle and is sampled by the measurement CCD; an image collected by the measurement CCD is analyzed and calculated by the calculation module to obtain a wearing diopter; and the control module is used for sending out a regulation command to correct the lens simulating wearing according to the analyzing and calculating result. The full-automatic comprehensive optometry unit has the advantage that the wearing diopter can be measured, and the optometry efficiency can be improved.
Description
Technical field
The present invention relates to a kind of full-automatic comprehensive optometry instrument.
Background technology
Common comprehensive optometry instrument mainly includes that combined lens and visual acuity chart, common optometry are subjective formula optometry,
Optometry process time is long, during patient repeatedly to have a rest, and need between optometrist and patient not
Break off a friendship mutually.As it is shown on figure 3, concrete optometry process is as follows:
1.: wear the number of degrees according to the regulation simulation of bore hole diopter
2.: patient is simulated wearing
3.: optometrist is by judging that patient wears rear diopter alternately
4.: optometrist sends regulating command and simulation is worn the number of degrees is modified
5.: repeat the most 4. step until revise to diopter optimum state
Mainly by optometrist patient worn after rear diopter makes subjective judgment during optometry and send, this process
The most more and there is certain subjectivity, cause prescription accuracy poor.
Summary of the invention
The invention aims to solve the problem that prior art exists, thus provide a kind of full-automatic comprehensive
Eye refractometer, can improve optometry efficiency, it is achieved self-help refraction, eliminates subjectivity error in common optometry, improves
Optometry accuracy.
The technical solution used in the present invention is: a kind of full-automatic comprehensive optometry instrument, including hardware components and software
Part, it is characterised in that described hardware components includes combined lens, visual acuity chart, infrared survey light source, standard
Straight eyeglass, spectroscope, illuminator, graticle and measurement CCD, described software section include control module and
Computing module, described infrared survey light source sends infrared light, through collimating lens, projects collimated light beam,
Light beam is sampled by measuring CCD through differentiation plate after retinal reflex, and the image measuring CCD collection passes through
Computing module analytical calculation, draws the diopter after wearing, then by control module according to the result of analytical calculation
Send regulating command and be modified simulating the eyeglass worn.
Described spectroscope, illuminator, graticle and the perpendicular lineal layout of measurement CCD.
Described infrared survey light source, collimation lens and spectroscope is horizontal linear distribution.
It is an advantage of the current invention that:
1. common optometry cannot be measured and be worn rear diopter, and the present invention can realize dioptric survey after wearing
Amount.
2. improve optometry efficiency.Optometry process fast and automatically, can realize self-help refraction.Common optometry process
Needing about 20 minutes, and period patient needs rest to loosen eyes for 1-2 time, the optometry time can be shortened by the present invention
To about 5 minutes, and patient was without having a rest.
3. eliminate subjectivity error in common optometry, improve optometry accuracy.
4. pair optometry process is programmed, it is achieved the Based Intelligent Control of optometry process.
5. alleviating optometrist workload, optometrist only need to attentively carry out the censorship after examination of visual acuity, right
The diagnostic result of patient is ensured.
Accompanying drawing explanation
Fig. 1 is optical principle schematic diagram of the present invention
Fig. 2 is intelligent measuring systems principle schematic
Fig. 3 is common optometry process schematic
Fig. 4 is optometry process schematic of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings, the present invention is described further:
As shown in Fig. 1,2,4, a kind of full-automatic comprehensive optometry instrument, including hardware components and software section,
Hardware components includes combined lens 8, visual acuity chart 9, infrared survey light source 1, collimation lens 2, spectroscope 3, anti-
Light microscopic 4, graticle 5 and measurement CCD6, software section includes control module and computing module, infrared survey light
Source 1 sends infrared light, through collimating lens 2, projects collimated light beam, and light beam is warp point after retina 7 reflects
Changing plate 5 and sampled by measuring CCD6, the image measuring CCD6 collection passes through computing module analytical calculation, draws
Diopter after wearing, then sent regulating command by control module according to the result of analytical calculation simulation is worn
Eyeglass be modified.Spectroscope, illuminator, graticle and the perpendicular lineal layout of measurement CCD.Infrared survey
Amount light source, collimation lens and spectroscope are horizontal linear distribution.
Optometry process of the present invention:
1: wear the number of degrees according to the regulation simulation of bore hole diopter
2: patient is simulated wearing
3: intelligent measuring systems is measured patient and worn rear diopter
4: intelligent measuring systems sends regulating command and simulation is worn the number of degrees is modified
5: repeat the most 4. step until revise to diopter optimum state
The main distinction with prior art:
During common optometry, simulation lenses fitted regulating command is mutual, by testing with patient by optometrist
Patient is worn after rear diopter makes subjective judgment and sends by light teacher, and simulates lenses fitted regulation in the present invention
Diopter after patient is worn by the intelligent measuring systems that instruction is made up of computing module and control module is surveyed
Send after amount.
Present invention achieves optometry and cross process automation, shorten the time required for optometry to a certain extent, and
And decrease patient's visual fatigue when optometry and the workload of optometrist.The present invention simulates lenses fitted
Regulating command by intelligent measuring systems, patient is worn after diopter measure after send, eliminate subjectivity
Factor and shorten the judgement time.The present invention is by electric control system, intelligent measure part and correcting lens portion
It is grouped into.It is reasonable in design, easy and simple to handle, and measurement error is little, it is adaptable to each optician's shop or regard light center etc..
The present invention that listed above is only is embodied as example, the invention is not restricted to above example, also
Can there be many deformation.Those of ordinary skill in the art can directly derive from present disclosure or join
The all deformation expected, are all considered as protection scope of the present invention.
