Description

Vision training device through movement of ciliary muscle

The present invention relates to a vision training device through the movement of ciliary muscles.

Eye muscles that are related to human vision include ciliary muscles, rectus muscles, and iris muscles. Vision can be protected or restored by exercising these eye muscles. In particular, vision is closely related to ciliary muscles, which are involuntary muscles and cannot be moved by human will. However, ciliary muscles adapt autonomously to these changes when the focal length of the lens placed in front of the eye is changed.

Japanese Patent Application Laid-Open No. 1996-257077 discloses a vision recovery training apparatus for performing a vision restoration training by arranging a lens and a display in a user's gaze direction and moving the arranged display to adapt the user's eyes. This provides the same effect as providing a diopter lens that is gradually changed to the user by changing the focal length between the user's eyeball and the display by the relative movement of the display. The above-described vision recovery training device is a principle of restoring vision by inducing movement of ciliary muscles of a user by changing a focal length.

Since the adaptation time according to the movement of the display refers to the adaptive visual characteristics of the individual, that is, the responsiveness of the capsular control muscles, the current status and trend of change are not considered as important factors related to visual acuity training and its performance. Did.

In addition, when the visual characteristics of each user are not considered, the training efficiency is reduced by repeatedly moving the display even in an explicit section where no training is required, whereas in an area where a long time is required to adjust the visual acuity, the display may not be sufficiently adjusted. Proper and efficient training was not guaranteed by moving.

Accordingly, an object of the present invention is to provide a vision training apparatus that can measure and manage the adaptive visual characteristics of the user.

In addition, another object of the present invention is to provide a vision training apparatus that can provide vision training reflecting the measured visual characteristics of the user adaptive.

The above object is to provide a housing having at least one eyepiece corresponding to the eye of the user, a display for displaying a target image in front of the user's eye, a lens disposed between the eyepiece and the display, and the display. A display moving unit capable of approaching and moving the eyepiece along the eyeline direction, a user input unit, and a control unit of the display moving unit to move the display and to change the eye and non-cian states of the eyeball of the user. The visibility corresponding to the threshold position of the display is achieved by including a control unit for storing the threshold information.

When the visibility threshold check input is provided through the user input unit, the controller may store the visibility threshold information corresponding to the threshold position of the display when the threshold check is input, thereby measuring a user's unique visual characteristics.

The control unit may effectively train the ciliary muscles of the user's eye by setting at least one training section in the moving region of the display and controlling the display moving unit to reciprocate the display within the training section.

The visual acuity training device further includes a sensor module for detecting an ocular eye state of the eye of the user, and the controller is configured to adjust an eye adaptation time to the target image based on an adaptation confirmation input input through the sensor module. By storing, the visual acuity characteristic of the user can be measured more conveniently.

(Effects of the Invention)

According to the present invention, it is possible to measure and manage the adaptive visual characteristics of the user of the user. In addition, by providing a customized vision training in consideration of the adaptive visual characteristics of the user, it is possible to improve the vision more effectively.

Hereinafter, a vision training apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a vision training device according to an embodiment of the present invention. The vision training apparatus has a pair of vision training units 120 disposed left and right inside the housing 110 indicated by a virtual line. Between the pair of sight training units 120, a blind plate 122 is installed to block the vision of the left and right eyes.

The vision training unit 120 is provided with an eyepiece 124 and a display 130 which are disposed to face each other along the line of sight. The display 130 displays a target image for vision training. The display 130 is movably coupled to the lead screw 151 through the movable body 152. The lead screw 151 is rotated by the drive motor 153, and the display 130 coupled with the movable body 152 moves relatively linearly with respect to the eyepiece 124 and the lens 140. . To this end, a guide slot 155 for guiding the sliding movement of the movable body 152 extends along the line of sight in the fixed support 154 fixed to the housing 110.

The upper surface of the housing 110 is provided with a user input unit 160 for receiving a user input from the user. The user inputs necessary information through the user input unit 160 or sets training conditions, training modes, and the like. In addition, the housing 110 may be provided with a strap (not shown) or a pair of glasses (not shown) for mounting on the face of the user.

The housing 110 generally has a rectangular parallelepiped shape, and the rear surface corresponding to the face portion of the user when worn has a curved shape corresponding to the contour of the face to provide a comfortable fit. In addition, the rear surface of the housing 110 is open corresponding to the eyepiece 124 through which the user can recognize the target image located inside the housing 110 via the eyepiece 124.

The display 130 displays the target image in front of the user's line of sight. The target image displayed on the display 130 may be a static image or a video such as a landscape photograph, a figure, a dot, or a geometric pattern. In order to provide such an image, the display 130 may be implemented as an electronic display device such as an LCD or an OLED. In addition, the display 130 may be implemented as a simple slide plate in which a predetermined target image is fixedly displayed. The display 130 may be implemented by mounting an external display such as a smartphone.

The lens 140 is mounted on the lens holder 142 and is disposed between the eyepiece 124 and the target image. The user recognizes the target image located in front of the eye through the eyepiece 124 and the lens 140. The lens 140 is implemented as a convex lens, but is not limited thereto. The convex lens expands the perspective of the image by changing the focal length between the user's eyeball and the image so that the user perceives the image as being farther than the actual distance. In addition, the lens 140 may be implemented as a polarized lens or a color lens as necessary to filter a part or all of the target image.

The display moving unit 150 moves the display 130 in the front-rear direction along the user's line of sight. The display mover 150 includes a lead screw 151, a movable body 152 movably coupled to the lead screw 151, and a drive motor 153 for rotating the lead screw 151.

The lead screw 151 is rotatably installed on the fixed support 154 provided in the housing 110, and is rotated by the drive motor 153. The rotational movement of the lead screw 151 is converted to the forward and backward sliding movement of the movable body 152. The movable body 152 is integrally coupled with the display 130, and the display 130 may be reciprocated in the front-rear direction by rotating the lead screw 151.

The shield plate 122 is installed inside the housing 110 to separate the left and right eyes' views. The blocking plate 122 allows the user to watch only the target image displayed by the display 130 corresponding to each eye.

The user input unit 160 is provided on the upper surface or the side of the vision training apparatus, and the controller 190 receives information or conditions input by the user through the user input unit 160. The user input unit 160 has a plurality of

user input buttons

161, 162, 163, 164, 165, and 166. Specifically, the buttons are composed of a power input button 161, a user selection button 162, a front movement button 163 and a rear movement button 164, a measurement mode selection button 165 and a training mode selection button 166. . The user input input through the user input unit 160 is received by the controller 190 and controls the vision training apparatus to perform an operation on the corresponding user input. The button type user input unit 160 may be replaced with a keypad, a touch screen, or the like. In the illustrated embodiment, the user input unit 160 is attached to the vision training apparatus, but may be implemented by a wired or wireless remote controller or replaced by an app of a mobile device such as a smartphone. The user input unit 160 may be implemented by a voice recognition method using a microphone.

The communication unit 170 communicates with an external device such as a smartphone, a tablet PC, a user server, or the like by wire or wirelessly. The visual acuity training device through the communication unit 170 may transmit data to or receive data from an external device.

The memory 180 stores user information, diopter conversion data, eyesight data, training data, and various data necessary for operation of the eyesight training apparatus. The diopter converted data refers to data obtained by converting respective positions of the display into diopter values within the moving range of the display 130. The memory 180 transmits the stored data to the controller 190, the communication unit 170, or the like under the control of the controller 190, or stores the received data in the memory 180.

The sensor module 200 is installed at a predetermined position in the housing 110 that outputs infrared rays toward the eyes of the user and receives the infrared rays reflected from the eyes. The sensor module 200 checks whether the user's eye is in the eye position. The sensor module 200 checks whether the eyeball of the user is changed from the normal eye state to the non-normal eye state or from the non-normal eye state to the normal eye state. Such a sensor module 200 is implemented by the same mechanism as the inspection principle of a generally used automatic refractometer. For example, the sensor module 200 calculates and uses the optical output unit for outputting infrared light toward the eye of the user, the light detector for detecting the reflected light reflected from the user's eye, and the focal length of the detected reflected light. The infrared ray output toward the eyeball includes a refraction checker for calculating a position where the focal point is focused in the eyeball. The sensor module 200 determines that the eyeball of the user is in the normal eye state when the focal point of the infrared light output toward the eye is formed in the retina. The sensor module 200 transmits an adaptation confirmation signal to the controller 190 when it is determined that the eyeball of the user is in the normal eye state. The sensor module 200 transmits the visibility threshold confirmation input to the controller 190 when the state of the eyeball of the user is changed from normal eyes to noncyanic eyes or from noncyanic eyes to normal eyes.

The controller 190 controls the overall operation of the vision training apparatus according to the embodiment of the present invention. The controller 190 may individually control the pair of displays 130. Because of this, the vision training device of the present invention is capable of visual training for the left eye, right eye, or both eyes. The controller 190 controls the movement of the display 130 by controlling the driving of the driving motor 153.

The vision training apparatus according to the embodiment of the present invention described above may be driven using a battery (not shown) mounted therein as a power source or connected to an external power source.

In the above-described embodiment, the display moving unit 150 has been described as a rotation driving method using the driving motor 153, but the display moving unit 150 may move in a manual driving method by a user's manipulation. This manual driving method may be implemented by connecting the lead screw 151 with a rotary knob that can be manually rotated, and then directly rotating the rotary knob.

As such, the vision training apparatus may move the display 130 along the line of sight by the driving motor 153 or manual operation. The focal length between the target image and the eyeball is changed by the movement of the display 130. By measuring and adjusting the adaptation of the user's eyes according to the change of the focal length, the user's vision characteristics or the user's vision restoration are restored. Training can be done for

3 is a flowchart illustrating a measurement mode process using the vision training device of the present invention by way of example, Figure 4 is a reference diagram for explaining the operation of the measurement mode and training mode of the vision training device of the present invention. Hereinafter, a process of performing a measurement mode using the vision training apparatus of the present invention will be described with reference to FIGS. 3 and 4.

First, the user presses the power input button 161 of the user input unit 160 to apply power to the vision training device. Thereafter, the user selects the measurement mode by pressing the measurement mode selection button 165 of the user input unit 160 after wearing the vision training apparatus (S110).

When the measurement mode is selected by the user, the controller 190 controls the driving motor 153 to move the display 130 to the remote position P2 (S120). The remote location P2 may be a position spaced most apart from the eyepiece 124 of the moving range MR of the display 130 or a position spaced a predetermined distance from the eyepiece 124.

After moving the display 130 to the remote position P2, the controller 190 controls the drive motor 153 to continuously or continuously move the display 130 in the direction from the remote position P2 toward the eyepiece 124. Intermittently moving (S130).

The controller 190 checks whether there is a visibility threshold confirmation input from the user input unit 160 (S140). The visibility threshold confirmation input is a signal provided to the controller 190 through the user input unit 160 when the eyeball of the user is changed from the normal eye state to the non-normal eye state. The user selects the button 162 of the user input unit 160 at the moment when the target image TI is clearly seen and flows as the display 130 moves, that is, when the visibility of the target image TI is changed. By pressing), input the visibility threshold confirmation input.

As such, the visibility position threshold confirmation input may be received through the above-described sensor module 200 without checking the threshold position based on the user input based on the recognition of the user. In this case, the sensor module 200 repeatedly checks whether the visibility of the user's eyeball changes every set period. That is, it is determined whether the user's eyeball is changed from the normal eye state to the non-cyanotic state, and when it is determined that the user's eye is changed to the non-cyanotic state, the control unit 190 transmits a visibility change confirmation input.

When the control unit 190 receives the visibility threshold confirmation input from the user input unit 160 or the sensor module 200, the control unit 190 determines the proximity of the threshold position of the display 130 when the visibility threshold confirmation input is input. Save to the location (P3) (S150).

Thereafter, the controller 190 controls the driving motor 153 to move the display 130 to the proximal position P1 (S160). The proximity position P1 is a position closest to the eyepiece 124 of the moving range of the display 130 or a position spaced a predetermined distance from the eyepiece 124.

After moving the display 130 to the proximity position P1, the controller 190 controls the driving motor 153 to continuously or intermittently move the display 130 from the proximity position P1 toward the remote position P2. To move (S170).

The controller 190 checks whether there is a visibility threshold confirmation input from the user input unit 160 or the sensor module 200 (S180).

As described above, when the visibility threshold confirmation input is provided from the user input unit 160 or the sensor module 200, the controller 190 may determine the threshold position of the display 130 at the time when the visibility threshold confirmation input is input. To store the remote visibility to the threshold position (P4) (S190).

When the display 130 moves toward the eyepiece to perform the above-described measurement mode, two visibility changes occur from the non-cyanic state to the cyanotic state and the transition from the cyanic state to the noncyanic state. In addition, when the display 130 moves remotely from the eyepiece, two visibility changes occur from the noncyanic state to the cyanotic state and from the cyanic state to the noncyanic state. The change point that properly represents the visual acuity characteristic of the user during the above four change of visibility is the change point that transitions from the fixed eye state to the non-eye eye state, that is, from the clear region to the non-clear region. Therefore, it is desirable to take this time of change as the unique visual characteristics of the user.

In the above description of the measurement mode, the display 130 first moved from the remote position P2 to the proximity position P1, but the movement order of the display 130 in the measurement mode is not limited thereto, but the proximity position is not limited thereto. The movement from the P1 to the remote location P2 may be made first.

The above-described measurement mode measures the display 130 while moving toward the eyepiece, and the user performs the above-described measurement mode process to determine the reliable near visibility threshold position P3 and the remote visibility threshold position P4. It is desirable to repeat and average the results to determine the near visibility threshold position P3 and the remote visibility threshold position P4.

Vision training apparatus according to an embodiment of the present invention by performing the above-described measurement mode, it is possible to check the unique visibility threshold information for each user. The visibility threshold information is set based on the threshold position value described above, and the threshold position value is set as it is, expressed as a distance value of the display 130 from the reference position, or expressed as a diopter converted value at the position. Can be. Such visibility threshold information may be used as an important parameter for evaluating visual acuity of a user as a factor related to a user's control ability. In addition, through the measurement mode by identifying the user's visual characteristics and by providing a customized vision training in consideration of the identified visual characteristics, the effect of the improvement of vision can be maximized.

Figure 5 is a flow chart for illustratively explaining the training mode process using the vision training device of the present invention. Hereinafter, a process of performing a training mode using the vision training apparatus of the present invention will be described with reference to FIG. 4 together with FIG. 5.

The user presses the power input button 161 of the user input unit 160 to apply power to the vision training apparatus. Thereafter, the user selects the training mode by pressing the training mode selection button 166 of the user input unit 160 after wearing the vision training apparatus (S210).

When the training mode is selected by the user, the controller 190 sets at least one training section within the moving range MR of the display 130 (S220).

In addition, the controller 190 may include a clear zone R1, a near non-sight zone R2 based on the near visibility threshold position P3 and the remote visibility threshold position P4 determined through the measurement mode for visual training. You can set the remote non-station time zone (R3). Here, the domain R1 is an area between the near visibility threshold P3 and the remote visibility threshold P4.

Vision training device of the present invention is a training in the inverse region (R1), the inverse training mode, training in the near-screaming zone (R2) and remote screaming zone (R3) outside of the clear zone (R1), manifestation The cross-training mode for training over the inside and outside of the station R1 and the extended training mode for training in a predetermined area inside or outside the clear area R1 may be performed.

Vision training is performed by reciprocating the display 130 within the set training interval (S230). The display 130 may move continuously or intermittently in a manner of repeatedly moving by a predetermined distance. Vision training may be performed by repeatedly moving the display 130 by the set separation distance within the set training interval and waiting for the set training time. Alternatively, vision training may be performed by continuously moving the display 130 within the set training interval. The movement of the display 130 has the same effect as replacing the lenses having different diopter values in the visual direction between the user's target image and the user's eyeball.

By this training operation, the ciliary muscles of the user are contracted or relaxed to adapt to the change of focal length with the target image TI which changes with the movement of the display 130. By repeatedly performing the above-described training operation, the ciliary muscles contract or relax repeatedly, thereby strengthening the muscular strength of the ciliary muscles.

The user may select the training of his or her preference from each of the above-described trainings and perform the visual training. These training modes may be directly selected by the user, but may be automatically selected by the controller 190.

When the user selects the control extension training mode, the control extension training intervals TR1 and TR3 may be automatically set by the controller 190 or directly by the user.

When the controller 190 automatically sets the adjustment extension training intervals TR1 and TR3, the controller 190 is spaced apart from the determined proximity visibility threshold position P3 or the remote visibility threshold position P4 by a distance set. The proximity training threshold position P5 or the remote training threshold position P6, which is the position, is determined first. In this case, the distance spaced to determine the proximity training threshold position (P5) or remote training threshold position (P6) may be set differently according to the age of the user. The controller 190 adjusts the range between the proximity visibility threshold position P3 and the proximity training threshold position P5 or the range between the remote visibility threshold position P4 and the remote training threshold position P6. TR1, TR3).

When the user directly sets the control extension training sections TR1 and TR3, the process of setting the control extension training sections TR1 and TR3 may be performed through the following process.

The user wears the vision training device and initiates an operation for setting the adjustment extension training section. The controller 190 causes the display 130 to display a predetermined target image TI and controls the display moving unit 150 to control the display 130 to the near visibility threshold position P3 or the remote visibility threshold position ( Move to any position of P4). In the following description, it is assumed that the display 130 is moved to the proximity visibility threshold position P3 for convenience of description.

The control unit 190 spaces the display 130 located in the proximity visibility threshold position P3 in the direction of the proximity position P1 by a predetermined distance unit, and then repeats the measurement operation of maintaining the position for the set waiting time. Control 150. If the target image TI recognized by the lens 140 does not become clear even after the set waiting time elapses, the user presses the user selection button 162 through the user input unit 160 to perform the proximity training threshold check signal. Enter. When the control unit 190 receives the proximity training threshold check signal through the user input unit 160, the control unit stops the measurement operation and determines the position of the display 130 at the time when the proximity training threshold check signal is received. Set to).

The separation unit set to determine the above-described control expansion training intervals TR1 and TR3 may be set differently according to the width of the clear region R1 determined above. For example, when the width of the clear region R1 is wide, the width of the control extension training sections TR1 and TR3 may be set wider. In addition, the waiting time set for determining the control expansion training intervals TR1 and TR3 may be set differently according to the age of the user. For example, the higher the age, the longer the waiting time may be set.

The determined extension training intervals TR1 and TR3 reflect the range of the accommodation force reserve of the user's eye. When performing the visual acuity training in the control expansion training intervals TR1 and TR3, the user's vision improvement may be improved by further expanding the user's control ability and control power.

When the eyesight training is completed, the eyesight training apparatus ends the training operation and stores the training data in the memory 180. The training data includes time information until the end of one cycle of training, which training mode, and what training conditions the vision training was performed. The training data is stored for each user, and by analyzing the stored training data, the degree of improvement of eyesight of the user according to the training can be checked. The user can check the degree of vision improvement to effectively set the future training plan and training direction.

In the vision training apparatus according to the embodiment of the present invention described above, the proximity visibility threshold position P3 and the remote visibility threshold position P4 corresponding to the user's current visual acuity are measured, and the training is performed based on the measured threshold position. Since the section can be set, the improvement of vision can be maximized.

FIG. 6 is a flowchart illustrating another training method performed using the vision training apparatus according to an exemplary embodiment of the present invention, and FIG. 7 is a reference diagram for explaining the training method illustrated in FIG. 6.

When the visual acuity training, the display 130 gradually moves the set training interval or moves a predetermined distance and then waits for a set waiting time. In this case, when the display 130 sets the waiting time after the movement in consideration of the visual characteristics of the individual user, vision improvement through vision training may be more effectively performed.

In order to set the waiting time in consideration of the visual characteristics of each user, the controller 190 controls the display moving unit 150 to position the display 130 at any one of the plurality of measurement positions (S310). For convenience of explanation, the display 130 is moved from the first measurement position MP1 to the second measurement position MP2 by way of example.

The controller 190 confirms whether the adaptive confirmation input is input through the user input unit 160 or the sensor module 200 (S320). The adaptive confirmation input is a signal indicating that the target image recognized by the user is cleared. That is, it is a signal indicating that the eyeball of the user is in the normal eye state.

The adaptation confirmation input may be input through the user input unit 160 or selectively through the sensor module 200.

When input through the user input unit 160, the user inputs the adaptive confirmation input by pressing the user selection button 162 of the user input unit 160 at the second measurement position MP2 when the target image is clear. When input through the sensor module 200, the sensor module 200 repeatedly checks the eye ocular state of the user's eye, and transmits the adaptive confirmation input to the controller 190 when the user's eye is the eye ocular state. .

When the adaptation confirmation input is input, the controller 190 stores an adaptation time for the corresponding measurement position MP2 (S330). Herein, the adaptation time means a time until the adaptation confirmation input is input after the display 130 moves to the second measurement position MP2. This adaptation time will have different values depending on the visual characteristics of the user. In the vision training apparatus according to the present invention, the position of the display 130 may be converted into a predetermined diopter value, and thus, each measurement position may be provided to the user in diopter conversion value.

The above-described adaptation time checking operation may be performed for all of the plurality of measurement positions MP1, MP2, MP3, MP4, MP5, MP6, MP7, MP8, MP9, and MP10, respectively. The measurement of the adaptation time for each measurement position is preferably measured according to the moving direction of the display 130. This is because the adaptation time may be different depending on the position of the display 130 located before the target image is recognized even in the adaptation time for the same measurement position.

When the adaptation time for each of the plurality of measurement positions is determined, the controller 190 sets one of the holding time or the moving speed V of the display for each position by reflecting the determined adaptation time (S340). The holding time is a time at which the display 130 stays at the corresponding position, and the moving speed V means the speed of the display 130 passing through the corresponding position.

After the holding time or the moving speed V is determined, the control unit 190 controls the display moving unit 150 so that the display 130 stays for the set holding time at the corresponding position or passes the position at the set moving speed ( S350).

As mentioned above. Performing visual acuity training in consideration of the adaptation time for each measurement position is to perform visual acuity training in consideration of the adaptation ability of the user. Therefore, it is possible to perform the visual acuity training efficiently and at the same time to effectively strengthen the ciliary muscle through visual acuity training.

In addition, as shown in FIG. 7, the user's adaptability to the target image according to the movement of the display 130 is high in the clear region R1. Accordingly, the training area may be increased by shortening the speed at which the display 130 moves or shortening the staying time in the clear region R1. On the other hand, in the near-sight-view area R2 and the remote-sight-view area R3, the adaptation time of the user's eye is relatively low because the time to adapt to the target image is longer. Therefore, in the region where the adaptation time is short, the width of the training section TR is relatively large, and in the region where the adaptation time is long, the width of the training region is relatively small, so that the user can obtain an effective training effect without excessive load during the training. You can do that.

As described above, the display staying time in each training section, that is, the movement speed of the display and the width of the training section are variably set in consideration of the user's adaptation time, thereby further maximizing the effect of vision improvement.
