Description

Technical Field

[0001] The present invention relates to the technical field of vision correction, and in particular to an integrated optical correction and training device capable of adaptively tracking the axis of astigmatism. Background Art

[0002] Astigmatism is a vision disorder that causes light rays to not focus simultaneously on the bridge of the eye, resulting in a blurry or distorted image. The main symptoms of astigmatism include blurred or decreased vision and eye strain. In severe cases, it may cause torticollis and headaches. Accompanying symptoms include distorted vision and tilting the head due to difficulty seeing clearly.

[0003] Astigmatism is a common refractive error problem that seriously affects the patient's visual quality. Most of the astigmatism correction devices currently on the market use a fixed axis correction mode, which makes it difficult to track in real time the dynamic changes in the astigmatism axis caused by eye movement and eye muscle changes, resulting in poor correction effects. In addition, the existing equipment is relatively single in function, usually only having a correction function, lacking an effective training module, and unable to fundamentally improve the patient's eye muscle adjustment ability and visual function, making it difficult to meet the patient's comprehensive vision recovery needs. In addition, existing correction devices often ignore the impact of environmental factors on vision correction, and do not have the ability to monitor the state of eye muscles in real time, and cannot provide patients with a more scientific and comprehensive vision correction solution. For this reason, an integrated optical correction training device with adaptive tracking of the astigmatism axis is proposed. Summary of the Invention

[0004] The present invention provides an integrated optical correction training device with adaptive tracking of the astigmatism axis to solve the problem raised in the above background technology that most of the astigmatism correction devices on the current market adopt a fixed axis correction mode, which makes it difficult to track the dynamic changes of the astigmatism axis caused by eye movement and eye muscle changes in real time, resulting in poor correction effect. In addition, the existing devices are relatively single in function, usually only have correction functions, lack effective training modules, and cannot fundamentally improve the patient's eye muscle adjustment ability and visual function, making it difficult to meet the patient's comprehensive vision recovery needs.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0009] A further improvement of the technical solution of the present invention is that the control terminal is internally provided with an image recognition algorithm module, an optical correction module, a training module, a control processing module, a bioelectric signal feedback module and an environmental adaptation execution module. The image recognition algorithm module collects the patient's eye image information in real time through a photoelectric sensor array, calculates the angle and position information of the astigmatism axis and transmits it to the control processing module.

[0010] A further improvement of the technical solution of the present invention is that the optical correction module adjusts the voltage of the liquid crystal lens group and the filter spectral range according to the astigmatism axis position data transmitted by the control processing module to achieve precise optical correction of astigmatism.

[0011] A further improvement of the technical solution of the present invention is that the training module is provided with a plurality of training modes, which is used to automatically generate a personalized training plan according to the patient's vision condition, correction stage and bioelectric signal feedback data, control the optical correction module to generate optical stimulation, and guide the eye muscle adjustment training.

[0012] A further improvement of the technical solution of the present invention is that the bioelectric signal feedback module is used to pause training and prompt the patient to rest, play relaxation guidance audio or display soothing images when the bioelectric signal sensor detects excessive fatigue of the eye muscles.

[0013] A further improvement of the technical solution of the present invention is that the environmental adaptation execution module is used to automatically adjust the brightness, contrast and spectral transmittance of the optical correction module according to the detection data of the ambient light sensor.

[0014] A further improvement of the technical solution of the present invention is that the control processing module serves as a core control unit, and is used to receive the astigmatism axial position data of the axial position detection module, the eye muscle bioelectric signal data of the bioelectric signal monitoring module, and the ambient light data of the ambient light sensor.
