Description

Technical Field

[0001] This invention relates to the field of optometry calibration technology, and more specifically to an automated optometry calibration device. Background Technology

[0002] Optometrists, used to examine the focusing of light after it enters the eye, are widely used in hospitals and optical shops. The accuracy of their test data affects the accuracy of eyeglass prescriptions and the health of eyeglass wearers. Optometrists are also listed in the National Mandatory Verification Catalogue of Measuring Instruments, making it an indispensable task in metrological verification work. Automated optometrist testing devices can greatly improve verification efficiency and play a positive role in ensuring accurate measurements and controlling the quality of eyeglass prescriptions from the source.

[0003] Currently used refractometer calibration equipment lacks a device that integrates all simulated eyes into a single portable unit. Instead, traditional detachable devices are still in use, requiring frequent replacement of the simulated eyes at different calibration points to meet the needs of the entire calibration process. This presents the following problems: First, frequent loading and unloading of simulated eyes is inefficient; second, frequent handling of the simulated eyes can easily scratch and soil them, affecting data accuracy; third, the bracket position changes with each simulated eye replacement; and fourth, the refractometer needs to be moved to align with the simulated eyes at different calibration points, increasing calibration time. Summary of the Invention

[0004] The purpose of this invention is to provide an automated refractometer calibration device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution:
