Embodiment 1

[0045] Example 1, such as image 3 As shown, the specific process of distance detection in the present invention:

[0046] Step 1001: After the user wears the refractive correction device, the sensor starts to be activated, and the distance sensor is activated.

[0047] Step 1002: the distance sensor starts to collect data.

[0048] The distance sensor mainly collects the distance between the user's eyes and the object facing him.

[0049] Step 1003: The core control module analyzes the collected distance sensor data, the current refractive correction protection in the core control module is set to myopia protection, and judges whether the eye distance environment meets the correction conditions through the data.

[0050] For example: when correcting myopic refraction, the distance warning threshold and reminder times are preset on the refractorometer, and the preset distance warning threshold and reminder times can be manually increased or decreased according to the vision ...

Embodiment 2

[0056] Example 2, such as Figure 4 Shown, the concrete flow process of light intensity detection among the present invention:

[0057] Step 2001: After the user wears the refractive correction device, the sensor starts to be activated, and the light intensity sensor is activated.

[0058] Step 2002: the light intensity sensor starts to collect data.

[0059] The light intensity sensor mainly collects the light intensity when the user uses the eyes. The light intensity sensor converts the ambient light intensity into an electrical signal, and the signal output by the ambient light sensor changes accordingly for different ambient light intensities. Light intensity refers to the luminous flux of visible light received per unit area, which is used to indicate the intensity of light and the amount of illumination of the surface area of ​​an object.

[0060] Step 2003: The microprocessor analyzes the collected light intensity data, and judges whether the light environment of the...

Embodiment 3

[0067] Example 3, such as Figure 5 As shown, the specific flow of the user's head state detection in the present invention:

[0068] Step 3001: After the user wears the refractive correction device, the sensor starts to be activated, and the head state sensor is activated. Step 3002: The head state sensor starts to collect data. The head state sensor mainly collects the head posture data and the user's head movement state data when the user uses the eyes.

[0069] Step 3003: The microprocessor analyzes the collected head state data, and judges whether the current head state environment meets the correction condition through the data.

[0070] Step 3004: Through the analysis of the collected data, determine whether the sitting posture state in the head state in the current user's eye environment is correct, and whether the head is in a state of violent movement.

[0071] Step 3005: According to step 3004, when it is judged that the user's eye posture state is incorrect, rem...

Abstract

The invention discloses a use method of a refractive correction instrument. The refractive correction instrument collects eye use environment data of a user in real time; the collected environment data is compared with preset eyesight protection data and characteristic parameters of the refractive correction instrument, according to comparison results, an alarming reminding part is started or thecharacteristic parameters of the refractive correction instrument are adjusted, and a good eye use environment is provided for the user in real time; according to the eye use environment, the blinkingfrequency of eyes is controlled by a blinking control mechanism in a physical mode in real time to conduct refractive adjustment on the eyes; refractive correction time and parameters of the user arecounted by a refractive corrector, and the counted data and the correction progress and effect which are obtained through analysis according to the counted data are displayed to the user through a display unit or a projection unit; communication connection is built between the refractive correction instrument and an external client, the counted data is uploaded to the external client, and the correction progress and effect can be checked through the external client. By means of the method, the deflects which exist in the prior art are overcome, and damage caused by refractive correction to the eyes of the human body is reduced.

Description

technical field [0001] The invention belongs to the field of medical and health care equipment, and in particular relates to a method for correcting eye refraction. Background technique [0002] With the development of scientific and technological progress, people widely use various electronic products, such as mobile phones, televisions, electronic computers, tablet computers, etc. Adverse environment reduces the number of times the eyes blink and constantly self-regulates, thus causing refractive errors of the human eye. [0003] At present, there are three main technologies for correcting the diopter of the human eye: 1. Orthokeratology glasses (OK lens); 2. Corneal surgery: PPK, LASIK, LASEK; 3. Intraocular lens implantation. The use of these technologies has damaged the cornea and lens of the human eye, and the harm and side effects caused are not worth the candle. Contents of the invention [0004] In order to solve the technical problems raised by the above-mentio...
