Example Embodiment

[0023] The present invention will be further described below in conjunction with the drawings:

[0024] Such as figure 1 , 2 As shown in 4, a fully automatic comprehensive refractometer includes a hardware part and a software part. The hardware part includes a combined lens 8, an eye chart 9, an infrared measuring light source 1, a collimating lens 2, a beam splitter 3, a mirror 4, Scribe board 5 and measurement CCD6, the software part includes control module and calculation module, infrared measurement light source 1 emits infrared light, passes through collimator lens 2, and projects a parallel beam. The beam is reflected by retina 7 and is sampled by measurement CCD6 by differentiation plate 5. Measure the image collected by the CCD6 through the calculation module analysis and calculation to obtain the refraction after wearing, and then the control module sends out adjustment instructions according to the analysis and calculation results to correct the simulated wearing lens. ...

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 [0001] The invention relates to a fully automatic comprehensive optometry instrument. Background technique [0002] Ordinary comprehensive optometry mainly includes combined lenses and eye charts. Ordinary optometry is subjective optometry. The optometry process takes a long time. During the process, the patient needs to take multiple breaks and requires constant interaction between the optometrist and the patient. Such as image 3 As shown, the specific photometry process is as follows: [0003] ①: Adjust the simulated wearing degree according to the naked eye diopter [0004] ②: The patient simulates wearing [0005] ③: The optometrist judges the diopter after the patient wears it interactively [0006] ④: The optometrist issues an adjustment command to correct the simulated wearing degree [0007] ⑤: Repeat steps ②③④ until corrected to the best state of diopter [0008] Optometry is mainly issued after the optometrist makes a subjective judgment on th...
