Detailed ways

The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

The invention designs a method for using a refractive correction instrument, which comprises a corresponding sensor for collecting various environmental data, an alarm unit for alerting the user, a blink control mechanism, an electronic color changing lens, and a manual Tear container (the artificial tear container for storing artificial tears and heating function), display or projection unit, microprocessor for data processing, calculation and generation of control commands, for refractive corrector and peripheral customers The communication unit (for example, a wireless communication chip or a wired transmission serial port) for performing communication connection, and the peripheral client may be a smart phone, a tablet computer or a PC. The internal structure of the refractive correction instrument is shown in Figure 1.

The method of using the refractive correction instrument is shown in Figure 2, and the specific process is as follows.

Step 1: The user wears the refractive corrector and presses the start switch. The refractive corrector collects the environmental data of the user's eye in real time.

The environmental data of the user's eye includes the distance data of the user's eyes and the front view object, the light intensity data of the external environment, the user's head state data, the ultraviolet data of the external environment, the image data of the eyeball and the periphery of the eyeball, and the artificial tears in the refractive correction instrument. At least one of temperature data and user's blink data.

Step 2: The refractive correction instrument compares the collected environmental data with the preset vision protection data and the characteristic parameters of the refractive correction instrument, and activates the alarm prompt function or adjusts the characteristic parameters of the refractive correction instrument according to the comparison result, and provides the real-time data. The user has a good eye environment. The characteristic parameters of the refractive corrector include at least one of light transmittance of the electronic color lens, lens color of the electronic color lens, and heating temperature of the artificial tear.

Comparing the image data of the eyeball and the periphery of the eyeball in the environmental data with the data about the image in the vision protection data, the image data including at least one feature object of the iris, the sclera, the pupil, the teardrop, and the blink, when in the environmental data When the image data is different from the image data in the vision protection data, the alarm prompts the user or stops the correction.

Comparing the acquired user head state data with the data about the head movement in the preset vision protection data, determining whether the current user's head is in a state of vigorous exercise, and if so, the alarm prompts the user to stop correcting; meanwhile, The acquired user head state data is compared with the data about the head posture in the preset vision protection data to determine whether the user's head is in the correct posture. If not, the alarm prompts the user to adjust the sitting posture.

Comparing the distance data of the user's eyes and the front view object in the environmental data with the distance data in the preset vision protection data, if the distance between the user's eyes and the front view object is smaller than the distance in the vision protection data, the alarm prompts the user to pay attention Eye, if the distance between the user's eye and the front view object is still less than the preset time threshold after the prompt, the refractive corrector makes the user at the normal blink frequency through the blink control mechanism, or controls the electronic color lens. The light transmittance, at this time, there is an action of instantaneously maximizing the reduction of the light transmittance of the lens, which is the same as the normal blink frequency of the human being, simulating the blinking action of the user.

Comparing the light intensity data of the external environment in the environmental data with the transmittance of the electronic color lens in the characteristic parameters of the refractive corrector to determine the light intensity of the light entering the user's eyes, and the light intensity of the light entering the user's eyes. When the light intensity upper limit threshold is greater than the preset vision protection data, the refractive corrector adjusts the light transmittance of the electronic color lens so that the light intensity of the light entering the user's eyes is smaller than the upper limit of the light intensity in the vision protection data, when entering When the light intensity of the user's eyes is less than the lower limit of the light intensity in the preset vision protection data, the alarm prompts the user to pay attention to the eye.

The ultraviolet data of the external environment in the environmental data is compared with the color of the electronic color changing mirror in the characteristic parameters of the refractive corrector to determine the ultraviolet intensity entering the user's eyes, and the ultraviolet intensity entering the user's eyes is greater than the preset visual protection data. The mid-ultraviolet intensity threshold, the refractive corrector increases the depth of the color of the electronic color lens, so that the ultraviolet intensity entering the user's eyes is less than the ultraviolet intensity threshold in the visual protection data.

Comparing the temperature data of the artificial tear in the refractive correction instrument in the environmental data with the temperature threshold in the preset vision protection data, when the temperature of the artificial tear in the refractive correction instrument is lower than the temperature threshold in the vision protection data, The refractive correction device adjusts the heating temperature of the artificial tears.

Step 3: The blink correction device is provided with a blink control mechanism. According to the eye environment, the blink control mechanism physically controls the blink frequency of the eye in real time to perform refractive adjustment on the eye.

Eye refractive adjustment is affected by environmental data and is related to the user's blink frequency. The higher the blink frequency of the user, the smaller the eye refractive adjustment is affected by the environmental data; when the user's eye environment is poor, the blink control mechanism makes The user's blink frequency is at a normal level, thereby reducing the influence of the poor eye environment on the eye's refractive adjustment; when the user's eye environment is good, the blink control mechanism reduces the user's blink frequency and increases the good environment to the eye. The light is adjusted. When the eye is lowered in the gaze state, the refractive corrector adds artificial tears to the surface of the eye to moisten the eye and enhance the ability of the eye to adjust the refractive power.

The specific implementation of certain steps of the present invention will be described below in conjunction with the six embodiments.

Embodiment 1, as shown in FIG. 3, the specific process of distance detection in the present invention:

Step 1001: After the user wears the refractive corrector, the sensor is started, and the distance sensor is activated.

Step 1002: The distance sensor begins to collect data.

The distance sensor mainly collects the distance between the user's eye and the face object.

Step 1003: The core control module analyzes the collected distance sensor data, and the current refractive correction protection in the core control module is set to myopia protection, and the data determines whether the eye distance environment satisfies the correction condition.

For example, when correcting myopic refraction, the preset distance warning threshold and the number of reminders on the refractive correction instrument, the preset distance warning threshold and the number of reminders can be manually increased or decreased according to the visual needs of different users, or can be performed through the terminal. Adjustment; if the distance warning threshold is 20cm, it can be manually adjusted to 25cm according to the demand; when the eye distance is less than 25cm, the duration is greater than 5 seconds, the user is reminded.

Step 1004: Determine whether the current user's eye distance is close by collecting data analysis.

Step 1005: According to step 1004, it is judged that the distance data in the current eye environment is good, and the distance data reaches the requirement of correcting the execution condition, and enters a state to be corrected.

Step 1006: According to step 1004, it is judged that the distance data in the current eye environment is poor, and the requirement for correcting the execution condition cannot be met, and the user is reminded to pay attention to the eye and correct it.

For example, when the distance data in the current user environment is less than the preset distance warning threshold of 35 cm, the user's voice "Please pay attention to the eye distance" is issued, and the user hears the sound and adjusts the distance.

Step 1007: If the reminder is invalid, when the set time threshold is exceeded, the blink control system controls the normal blink of the eye or the electronic color change lens to instantaneously simulate the blinking action, and there is an instantaneous maximum to reduce the transmittance of the lens, the instantaneous action frequency and The normal blink frequency is the same.

Embodiment 2, as shown in FIG. 4, the specific process of the light intensity detection in the present invention:

Step 2001: After the user wears the refractive corrector, the sensor is started, and the light intensity sensor is activated.

Step 2002: The light intensity sensor begins to collect data.

The light intensity sensor mainly collects the light intensity when the user uses the eye. The light intensity sensor converts the ambient light intensity into an electrical signal, and the signal output by the ambient light sensor changes for different ambient light intensities. Light intensity is the amount of light that is received by visible light per unit area and is used to indicate the intensity of the illumination and the amount by which the surface area of the object is illuminated.

Step 2003: The microprocessor analyzes the collected light intensity data, and determines whether the eye light environment satisfies the correction condition by using the data.

Step 2004: Determine the strength of the light intensity data in the current user's eye environment by collecting data analysis.

Step 2005: According to step 2004, when the light intensity of the light entering the user's eyes is strong, the light transmittance of the electronic color lens is adjusted according to the light intensity collected by the refractive correction instrument, so that the light intensity of the light entering the user's eye conforms to the correction. Condition, enter the state to be corrected.

For example, in the summer, because the light is relatively strong, when the light is detected to be too strong, the light transmittance of the electronic lens is automatically adjusted, so that the light intensity entering the eye satisfies the corrective condition and enters a state to be executed.

Step 2006: According to step 2004, it is judged that the light intensity data in the current eye environment is poor, and the requirement for correcting the execution condition cannot be reached, and the user is reminded to pay attention to the eye.

For example, if the current user is reading in a weak light environment, and the light intensity data collected by the refractive corrector is less than the preset light intensity protection warning threshold, the user is reminded that the light is “now dark” and the user hears the sound. Look for places with good light.

Step 2006: According to step 2004, when the light intensity data in the current eye environment is good, the state to be corrected is directly entered.

Embodiment 3, as shown in FIG. 5, the specific process of detecting the state of the user's head in the present invention:

Step 3001: After the user wears the refractive corrector, the sensor is started, and the head state sensor is activated.

Step 3002: The head state sensor begins to collect data. The head state sensor mainly collects head posture data and user head motion state data when the user uses the eye.

Step 3003: The microprocessor analyzes the collected head state data, and determines whether the current head state environment satisfies the correction condition by using the data.

Step 3004: By collecting data analysis, it is determined 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 vigorous motion state.

Step 3005: When it is determined according to step 3004 that the state of the user's eye posture is incorrect, the reminder is to urge the user to maintain the correct eye posture;

For example, when the user is reading, often there is a situation on the table or reading the book, the data detected by the motion correction sensor of the refractive correction device is compared with the preset head posture state data, and the user is judged. The head posture is not correct, and the refractive correction device sends a reminder sound "Please pay attention to the eye posture" so that the user can sit on the body and then read. By detecting the above incorrect posture, it is possible to prevent adolescent students from accelerating myopia due to an incorrect posture during lectures and reading.

Step 3006: According to step 3004, it is determined that the user is in a state of severe head movement, terminating the correction or reminding the user to remove the refractive correction instrument.

For example, when the user is in a strenuous exercise, such as running, the data detected by the motion state sensor of the refractive corrector is compared with the preset head motion state data, and when the motion of the user in the head motion state is relatively large, At this time, the eyes are not suitable for correction, the blinking system control is released, the eyes are blinded by the eyes, and the user is reminded to take off the refractive correction instrument to prevent the collision of the refractive corrector caused by accident and damage the eyes.

Step 3007: According to step 3004, it is determined that the user is seated correctly and the head movement is small, and the state to be corrected is entered.

Step 4001: After the user wears the refractive corrector, the sensor is started, and the image sensor is activated.

Step 4002: The image sensor begins to collect data. The image sensor mainly collects image information of the periphery of the eyeball and/or the eyeball, and identifies at least one feature image information included in the target image. For example, it is used to identify image information such as iris, sclera, pupil, tears, and blinks contained in the image.

Step 4003: The microprocessor analyzes the collected image information data, and determines whether the current eye image environment satisfies the correction condition by using the data.

Step 4004: Determine whether the image information in the current user's eye environment is abnormal by collecting data analysis.

Step 4005: Remind the user or stop the refractive correction when the image data is different from the eye protection data about the image according to step 4004.

For example, the current user during the correction process, due to fatigue or irregular correction, resulting in bloodshot on the sclera, tears and redness, image of the sclera or tears collected by the image sensor and image protection of the sclera or tears of the eye When the data is different, the user is reminded of the voice "Please pay attention to rest!", let the user stop the correction treatment, pay more attention to rest.

Step 4006: According to step 4004, when it is determined that the image data and the eye protection data about the image are not abnormal, the state to be corrected is entered.

Step 5001: After the user wears the refractive corrector, the sensor is started, and the ultraviolet sensor is activated.

Step 5002: The ultraviolet sensor starts collecting data. The UV sensor mainly collects the ultraviolet light intensity when the user uses the eye.

Ultraviolet light is a wavelength of light, for other wavelengths of light, for example, blue, red. The ultraviolet light has a wavelength width of 185-400 nm and can be divided into a UVC band of 185 nm to 270 nm, a UVB band of 270 nm to 315 nm, and a UVA band of 315 nm to 400 nm.

Step 5003: The microprocessor analyzes the collected ultraviolet data, and determines whether the current ultraviolet environment satisfies the correction condition through the data.

Step 5004: Determine the strength of the ultraviolet data in the current user's eye environment by collecting data analysis.

Step 5005: According to step 2004, when the ultraviolet light of the light entering the user's eyes is strong, the color of the electronic color lens is adjusted according to the light intensity collected by the refractive correction instrument, so that the ultraviolet light entering the user's eyes meets the correction condition and enters the state to be corrected. .

For example, in areas or seasons where UV intensity is high, the refractive corrector automatically adjusts the lens color if it detects high UV intensity, preventing the user from burning the eyes when correcting the eyes.

Step 5006: According to step 2004, when the light intensity data in the current eye environment is zero, the state to be corrected is directly entered.

Step 6001: After the user wears the refractive corrector, the sensor is started, and the temperature sensor is activated.

Step 6002: The temperature sensor begins to collect data. The temperature sensor mainly collects the temperature of artificial tears in the refractive correction instrument.

Step 6003: The microprocessor analyzes the collected temperature data, and determines whether the temperature environment of the artificial tears satisfies the correction condition in the current refractive correction instrument through the data.

Step 6004: Determine whether the temperature of the artificial tear is low by collecting data analysis.

Step 6005: According to step 6004, when the temperature of the artificial tear in the refractive correction instrument is low, the stored artificial tear temperature is heated. For example, in the cold winter season, when the temperature drops to ice, when the refractive correction instrument detects that the temperature data is too low, the temperature of the stored artificial tears is automatically heated to avoid the formation of ice when the temperature is too low. Pumping of artificial tears on the surface of the eye.

Step 6006: According to step 6004, it is determined that the temperature of the artificial tear in the refractive correction instrument directly enters the state to be corrected when the temperature of the human body is suitable.

The eyes are moist, enhancing the ability of the eye to adjust the refractive power.
