Detailed Description

Illustrative embodiments of the present application include, but are not limited to, diopter adjustment methods, apparatuses, and readable media for electronic devices and lenses thereof. The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

The embodiment of the application discloses electronic equipment, this electronic equipment possesses the function of intelligent regulation lens diopter, can effectively alleviate user's asthenopia. Specifically, the states of the ciliary muscle and the crystalline lens of the human eye change along with the change of the diopter of the glasses worn, so by formulating a diopter adjusting strategy, the diopter of the glasses worn by the user is continuously adjusted in the adjusting time period of the asthenopia according to the corresponding relation between the diopter and the time in the adjusting strategy, so that the states of the ciliary muscle and the crystalline lens of the eyes of the user change along with the change of the diopter in the adjusting time period of the asthenopia, and the asthenopia of the user is relieved. That is, in one triggered adjustment, a certain strategy is adopted to perform the adjustment instead of only using one fixed diopter value, so that a good effect is achieved.

For the sake of understanding, the clinical theoretical basis of the change in the state of the ciliary muscles and the crystalline lens of the human eye with the change in the diopter of the spectacles worn is first described. In particular, fig. 1A shows a graphical representation of the diopter of a human eye as a function of the diopter of the eyeglasses worn by the user when the distance at which the human eye is gazed at is constant or varies little, according to some embodiments of the present application. As shown in fig. 1A, when the diopter of the glasses worn by the user changes, the diopter of the human eye changes in a direction opposite to the changing trend of the diopter of the glasses, and the change amount is close to each other, so that the object watched by the human eye can be kept clear. For example, at second 5, the diopter of the eye is decreased by 1.7 diopters, and the diopter of the eye is increased by about 1.7 diopters; at the 10 th second, the diopter of the glasses increases from-2D by 1.7D to-0.3D, and the diopter of the human eye decreases from 2D to 0.3D. Therefore, when the user uses the eyes for a long time at a close distance, the diopter of the human eyes can be adjusted by adjusting the diopter of the glasses of the user and stimulating the human eyes to adjust the ciliary muscles and the crystalline lens so as to further relieve the eye fatigue of the user and prevent the aggravation of myopia or hypermetropia.

Based on the clinical theoretical basis, the embodiment of the application discloses a technical scheme for formulating a diopter adjustment strategy for a user so as to relieve visual fatigue of the user. It is to be understood that the diopter adjustment strategy of the present application can be established based on clinical experiments, clinical experience, or by a user, as will be described in detail below. For example, FIG. 1B illustrates a diopter adjustment strategy, as shown in FIG. 1B, the diopter to correct the user's vision is D ₀ E.g. 1D, for sustained eye use by the userTo a predetermined time, e.g. 10 minutes after the user continues to use his eyes, with T ₁ +T ₂ To adjust the diopter of the user's glasses periodically, for example: diopter of the user's eyeglasses is adjusted to D at 0 of each cycle ₀ +D ₁ E.g. 1.3D, maintaining the diopter T ₁ After a period of time (e.g. 10 minutes) the diopter of the user's glasses is adjusted to D ₀ +D ₂ E.g. 2D, and maintain T ₂ Time, for example 5 seconds. Therefore, the ciliary muscle of the user can be periodically tightened or loosened, so that the curvature of the crystalline lens is changed, the eye fatigue of the user is relieved, and the aggravation of myopia or hypermetropia is prevented.

It is understood that, in the embodiment of the present application, the electronic device having the diopter adjustment strategy may be various electronic devices having diopter-adjustable lenses, including but not limited to smart glasses, VR glasses, AR glasses, and the like, and the embodiment of the present application is not limited thereto.

It is understood that in some embodiments, the smart glasses 10 may also employ a diopter adjustment strategy to adjust the diopter of the smart glasses 10 upon receiving an instruction from a user.

At this time, the processor 100A/100B acquires the posture of the user from the posture detection module 109, acquires the movement data of the eyeballs of the user from the eyeball tracking module 106A/106B, starts a timer when the user keeps the head-down posture, and goes to step 502 when the time of the timer reaches 10 minutes.

For example, in some other embodiments, the conditions for triggering diopter adjustment may include: the user is in a heads-down position and the distance between the smart glasses 10 and the user's gaze point is less than a preset distance, for example less than 35cm. At this time, the processor 100A/100B acquires the posture of the user through the posture detection module 109, acquires the gaze point of the user from the eye tracking module 106A/106B when the user is in the head-down posture, and acquires the distance between the gaze point of the user and the smart glasses 10 through the infrared ranging module 108, and when the distance is less than 35cm, goes to step 502.

For example, in some other embodiments, the conditions that trigger diopter adjustment may include: the smart glasses 10 receive an instruction to start adjustment sent by the cell phone 30. Referring to fig. 3, the user sends an instruction to start adjustment to the smart glasses 10 through the application installed on the cellular phone 30, and the processor 100/100A goes to step 502 upon receiving the instruction.

For example, in some other embodiments, the conditions for triggering diopter adjustment may include: the smart glasses 10 detect an operation of starting adjustment by the user, such as tapping the smart glasses 10, pressing an adjustment key of the smart glasses 10, or the like. At this time, the processor 100/100A obtains acceleration data of the smart glasses 10 through the pose detection module 109, and when the acceleration data represents that the smart glasses 10 are subjected to a tapping operation, goes to step 502.

It should be noted that, in some embodiments, the user may also set the parameters of the trigger conditions through an application installed in the mobile phone 30. Referring to FIG. 6A, a user may enter the trigger condition setting interface by clicking on the "trigger condition setting" control 601. As shown in fig. 6B, the user may set the aforementioned preset time through the "trigger time" control 602, set the aforementioned preset distance through the "eye distance" control 603, and set the number of taps for triggering diopter adjustment through the "tap setting" control 604, and in other embodiments, the user may set different diopter adjustment strategies for different number of taps through the "add" control 6041. Therefore, the user can set the condition for triggering diopter adjustment according to the eye using state of the user and the eye using health care suggestion of the vision expert, so that the visual fatigue can be effectively relieved, and the myopia or hypermetropia can be prevented from deepening.

It is understood that, in other embodiments, the above-mentioned conditions for triggering diopter adjustment may be combined or separated, and other types of conditions for triggering diopter adjustment may also be set according to the structure of the smart glasses 10, the type of sensor, and the like, and the embodiments of the present application are not limited.

Step 502: and acquiring a diopter adjustment strategy. The diopter adjustment strategy can comprise the change of diopter of the trigger-adjusted electric control zoom lens 103A/103B along with time, whether to carry out cycle adjustment and the like. For example, in some embodiments, the memory 101A/101B may be pre-set with the curve of the diopter change with time, whether to perform the cyclic adjustment, and other parameters, so that the processor 100A/100B can directly read the curve and the parameters whether to perform the cyclic adjustment from the memory 101A/101B.

For example, in some embodiments, the smart glasses 10 may also preset a diopter adjustment strategy model and provide editable parameters of the diopter adjustment strategy model, which may be input by the user through an application installed on the mobile phone 30, such as the vision parameters of the user, the diopter of the electronically controlled zoom lens 103A/103B after triggering adjustment, and the like.

In particular, fig. 7A and 7B illustrate how a diopter adjustment strategy model may be entered via the cell phone 30 according to some embodiments of the present applicationAnd (5) an interface schematic diagram of the mobile phone 30 when the parameters are edited. As shown in fig. 7A, the user may enter the diopter adjustment strategy setting interface by clicking on the "diopter adjustment strategy setting" control 701. Referring to fig. 7B, the diopter adjustment strategy setting interface includes an "adjustment mode" control 702, an "adjustment curve" control 703, and a "curve parameter setting" control 704. The user may select an adjustment mode, including but not limited to "loop," "single," etc., by clicking on the drop-down arrow of the "adjustment mode" control 702. It is understood that in the "circulation" mode, the smart glasses 10 will periodically adjust the diopter of the electronically controlled zoom lenses 103A/103B according to the selected adjustment curve without triggering the exit from the current adjustment; in the "single shot" mode, the smart glasses 10 will only make one cycle of adjustments to the power of the electronically controlled zoom lenses 103A/103B according to the selected adjustment profile. The user can select the diopter adjustment strategy model preset in the smart glasses 10 through the "adjustment curve" control 703, and it can be understood that when the user selects one adjustment curve, for example, the curve 1, the mobile phone 30 will display editable parameters of the selected adjustment curve, and the user can complete the setting of the diopter adjustment strategy by inputting the editable parameters. For example, when the selected adjustment curve is curve 1, the mobile phone 30 displays the time-diopter curve corresponding to curve 1 and the editable parameter T of curve 1 ₁ 、T ₂ 、D ₁ And D ₂ The user inputting T ₁ 、T ₂ 、D ₁ And D ₂ The setting of the diopter adjustment strategy can be completed.

In other embodiments, the user may also customize the diopter adjustment strategy via an application installed on the cell phone 30 according to eye-use recommendations of the optometrist. Referring to fig. 7C, the user can adjust the diopter scale (diopter D relative to the diopter scale for correcting the user's near or far vision) by inputting different adjustment zones and corresponding diopter scale values for the different adjustment zones ₀ Amount of change) or accommodative value (amount of accommodation and diopter D to correct the user's myopia or hypermetropia ₀ The sum). The diopter corresponding to different adjustment intervals can be a constant; or can also be usedTo be a preset regulation curve, such as curve 1 shown in fig. 7B; it may also be a function of diopter change over time, e.g. D _t = f (T), wherein D _t Represents the adjustment amount, T represents the time of entering the current adjustment interval, f represents D _t Variation with T. Time in the interface of the custom tuning curve shown in FIG. 7C, a tuning interval [0,20 ] can be set]The adjustment amount in the range is 0.1D, and the adjustment interval [20,40 ]]Within the range, the adjustment is carried out according to the curve 1, the adjustment interval [40, 60 ]]In the range according to D _t And = 0.01T.

It is understood that, in some embodiments, the left eye and the right eye of the user may adopt different adjustment curves, and the user may set different adjustment curves for the left eye and the right eye according to the own vision parameter and/or the suggestion of the eyesight expert, which is not limited in the embodiment of the present application.

Step 503: and adjusting the diopter of the electric control focusing lens 103A/103B at least once according to the diopter adjusting strategy. The smart glasses 10 start a timer according to the change relationship between the diopter of the electrically controlled focusing lens 103A/103B and the time in the diopter adjustment strategy, and adjust the electrically controlled focusing lens 103A/103B to the corresponding diopter at different times. The specific adjustment process is different according to different diopter adjustment strategies, and will be described in detail below, and will not be described herein again.

In some embodiments, the driving module 102A/102B reads data of a storage unit in the memory 101A/101B for storing diopters of the first lens group 10A and the second lens group 10B in real time, and adjusts voltage and/or current for driving the electrically controlled focusing lens 103A/103B according to the read data, thereby adjusting diopters of the first lens group 10A and the second lens group 10B. At this time, when the diopter of the electronic control focusing lenses 103A/103B is adjusted, the processor 100A/100B can adjust the diopter of the electronic control focusing lenses 103A/103B only by writing the diopter value corresponding to the moment into the memory 101A/101B at different moments, so that the control flow can be simplified, the power consumption of the smart glasses 10 can be reduced, and the cruising ability of the smart glasses 10 can be increased.

It should be noted that, diopters of the electronic control focusing lens 103A and the electronic control focusing lens 103B are always adjusted at the same time, in some embodiments, the first lens group 10A and the second lens group 10B may perform communication negotiation through the bluetooth communication module 105A and the bluetooth communication module 105B, so as to adjust diopters of the electronic control focusing lens 103A and the electronic control focusing lens 103B at the same time, and improve user experience.

It is to be understood that, in other embodiments, the first lens group 01A and the second lens group 01B may also perform communication negotiation in other wired or wireless communication manners according to communication connection manners provided by the first lens group 01A and the second lens group 01B, which is not limited in this embodiment of the present application.

It will be appreciated that in some embodiments, the processor 100A/100B may store the diopter of the electronically controlled focusing lenses 103A/103B in the memory 101A/101B prior to diopter adjustment to facilitate resetting the diopter after diopter adjustment is exited.

As described above, according to the diopter adjustment method provided in the embodiment of the present application, after the diopter adjustment of the smart glasses 10 is triggered by the operation of the user and/or according to the eye using state of the user, the diopter of the smart glasses 10 can be adjusted at least once according to the eye using state of the user, for example, the eye using time, the watching distance, and the like, so that the ciliary muscle and the crystalline lens of the user's eye are relaxed, thereby relieving the asthenopia and preventing the myopia or hyperopia from deepening.

It is noted that, in some embodiments, the above steps 501 to 502 may be performed by one of the processor 100A and the processor 100B, for example, the processor 100A. At this time, when step 503 is executed, the processor 100A transmits the diopter data of the electronically controlled focusing lens 103B to the processor 100B through the bluetooth communication module 105A, and the processor 100B writes the diopter data into the corresponding storage unit, so that the power consumption of the processor 100B can be further reduced, and the cruising ability of the smart glasses 10 can be improved.

As shown in FIG. 9, wherein D ₀ For a user's corrective diopter of the glasses, i.e., for correcting the user's near or far vision, the accommodation curve is at 0 ₃ ]Within range, diopterThe adjustment amount is D ₃ I.e. the diopter of the electrically controlled zoom lens 103A/103B is D ₀ +D ₃ In [ T ] ₃ ，∞]Within the range, the diopter adjustment amount is 0, i.e., the diopter of the electrically controlled zoom lens 103A/103B is D ₀ . When the diopter of the smart glasses 10 is adjusted using the adjustment curve shown in fig. 9, at time 0 and T ₃ The ciliary muscle of the human eye can be correspondingly tightened or relaxed at any moment, so that the curvature of the crystalline lens is correspondingly changed, the visual fatigue can be relieved, and the myopia or hypermetropia of a user is prevented from being deepened.

Example 3

FIG. 11 illustrates a schematic diagram of a user-customized adjustment curve, according to some embodiments of the present application. As shown in fig. 11, the custom curve is divided into three time segments: in the interval of 0 to 20 minutes, the diopter adjustment amount is 0.1D, i.e. the diopter of the electrically controlled zoom lens 103A/103B is D ₀ +0.1D; in the interval from 20 to 40 minutes, the regulation curve is regulated according to curve 1 (the curve shown in fig. 1B); diopter adjustment D in the interval of 40-60 minutes _t =0.01T (wherein T is time, and the unit is min), namely, the diopter of the electrically controlled zoom lens 103A/103B is D ₀ +0.01T. Therefore, the user can define the adjusting curve according to the eye using condition of the user and the eye using proposal of the vision expert, and the intelligent glasses 10 can adjust the diopter of the electric control zoom lens 103A/103B according to the adjusting curve, thereby being beneficial to more effectively relieving the visual fatigue and preventing the myopia or the hyperopia from deepening.

Further, fig. 12 illustrates a flow chart of the smart glasses 10 adjusting the power of the electronically controlled zoom lenses 103A/103B according to a user-defined adjustment profile, according to some embodiments of the present application. The process is executed by the processor 100A and/or the processor 100B of the smart glasses 10, as shown in fig. 12, and includes the following steps.

Step 1201: and acquiring parameters of the custom adjusting curve and starting a timer. The processor 100A/100B obtains the adjustment interval of the custom curve and the corresponding adjustment curve from the memory 101A/101B. For example, according to the customized tuning curve shown in FIG. 11, the tuning interval includes [0,20 ]]、[20，40]And [40, 60 ]]And the corresponding regulating curves of the three intervals are respectively 0.1D, 1 and D _t ＝0.01T。

Step 1202: and acquiring the time t of the timer and determining the current adjusting interval and the corresponding adjusting curve according to the time t. The processor 100A/100B obtains the time t of the timer and determines an adjustment curve according to t and the adjustment interval obtained in step 1201. It is understood that when t is greater than the right boundary of the maximum interval of the customized curve, for example, when the customized adjustment curve is the adjustment curve shown in fig. 11, and t is greater than 60, the processor 100A/100B resets the diopter adjustment amount of the smart glasses 10, i.e., adjusts the diopter of the smart glasses 10 to the diopter before the adjustment according to the customized adjustment curve.

Step 1203: and judging the type of the adjusting curve, and adjusting according to the determined type of the curve. Illustratively, the types of the adjustment curve may include three types of "constant", "curve", and "function". The "curve" may be a curve preset in the memory 101A/101B of the smart glasses 10, or a curve customized by the user; the "function" is then the adjustment quantity D _t At the same time, the current regulation interval is enteredTime T.

When the type of the adjustment curve is "constant", the processor 100A/100B has a diopter D to the smart glasses 10 according to the "constant" ₀ +0.1D, refer to step 802 specifically, and are not described herein. When the type of the adjustment curve is "curve", the processor 100A/100B adjusts the diopter of the smart glasses 10 according to the corresponding adjustment method in the current adjustment section. For example, in the regulation interval [20,40 ]]In the range, the curve is curve 1 shown in fig. 1B, and the processor 100A/100B adjusts the diopter of the smart glasses 10 according to the steps 801 to 806. When the type of the adjustment curve is "function", a difference between t and a starting point of a current adjustment interval is determined, and the diopter of the smart glasses 10 is adjusted according to the difference. For example, in the regulation interval [40, 60 ]]Within the range, the regulation curve is D _t =0.01T, and at this time, T = T-40, that is, the adjustment amount is 0.01 × (T-40), the processor 100A/100B adjusts the diopter of the smart glasses 10 to D ₀ +0.01×(t-40)。

It is to be understood that the foregoing type of the adjustment curve and the adjustment manner for different types of adjustment curves are only examples, and a person skilled in the art may redefine the type of the adjustment curve and/or use other different control manners in other embodiments, which is not limited in the embodiments of the present application. Therefore, the diopter of the intelligent glasses 10 can be adjusted more reasonably according to the user-defined adjusting curve, and the visual fatigue of the user can be relieved, and the myopia or hypermetropia of the user can be prevented from being deepened.
