Technical Field

The present invention relates to an eye movement device, and more particularly, to an eye movement device which facilitates movement of an eye to relieve eye fatigue and improve vision.

Background

Myopia clearly shows near objects but not distant objects, due to the inability of the focus to pass through the lens in the eye, falling in front of the center of the retina.

The focus is adjusted by the crystal, when seeing the object at a close place, the crystal can become thick, and when seeing the object at a far place, the crystal can become thin, so that the position of the focus is adjusted. At this time, the thickness of the lens is adjusted according to the contraction and relaxation of the inner eye muscle around the lens.

Further, the outer muscles of the eyes (four rectus muscles, superior rectus muscles, inferior rectus muscles, lateral rectus muscles, internal rectus muscles, two oblique muscles, superior oblique muscles, and inferior oblique muscles) also assist the adjustment of the eyes, and when looking at a distance, the four rectus muscles are contracted to shorten the visual axis of the eyes, while the diameter of the eyes is lengthened to assist the stretching of the ciliary muscle, which is the inner muscles of the eyes, and when looking at a near position, the two oblique muscles are contracted to lengthen the visual axis of the eyes, while the diameter of the eyes is shortened to assist the relaxation of the ciliary muscle.

According to this feature, the inner eye muscle (ciliary muscle) and the outer eye muscle (four rectus muscles) of a myopic eye

Two oblique muscles) is weaker than normal, performing regular eye movements is very effective in preventing myopia and recovering from myopia. In view of this, korean utility model No. 91-2714 (1991.2.27) filed by the present applicant has been disclosed by utility model publication No. 93-1897 (1993.4.17), which cannot adjust the interval between a pair of lens barrels according to the user and is not suitable for children having a narrow interocular distance. Further, although it is necessary to appropriately block or release the external light according to the movement pattern, the conventional apparatus requires the user to detach the cover portion by himself, which is troublesome to use.

Therefore, it is required to develop an eye movement device capable of adjusting an interval between a pair of lens barrels according to a user and automatically opening or closing a cap portion according to a movement pattern.

Note that unless otherwise specified, the term "includes" or "including" a member means that another member may be included.

The terminology used in the description is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Unless the context clearly dictates otherwise, expressions in the singular include the plural. In the present specification, the terms "comprises" or "comprising" are intended to specify the presence of stated features, integers, steps, actions, elements, and components, or groups thereof, but do not preclude the presence or addition of one or more other features, integers, steps, actions, elements, or groups thereof.

Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Fig. 1 is a structural view of an eye movement apparatus 1 according to an embodiment of the present invention. The eye movement apparatus 1 includes a movement unit 10, a massage unit 20, an input unit 30, and a control unit 40. The movement section 10 is a member for providing a user of the eyeball movement device 1 with a plurality of movement patterns including a contraction or relaxation movement pattern of the rectus muscle and the oblique muscle, an iris movement pattern, and a retina movement pattern, and is located inside the housing 100. The moving portion 10 is described more specifically with reference to fig. 2 and 3.

Fig. 2 is an exploded view of the eye movement apparatus 1 according to an embodiment of the present invention. Fig. 2 shows a state in which the upper surface of the housing 100 is opened for convenience of explanation. Fig. 3 is a sectional view of the moving part 10 of the eye movement apparatus according to an embodiment of the present invention.

The moving part 10 includes a pair of first lens barrel parts 110, a cover part 120, and a cover adjusting part 130, and may include a second lens barrel part 111 into which the first lens barrel part 110 is inserted according to an embodiment of the present invention. The first lens barrel portion 110 has a first passage 1101 formed in the longitudinal direction, and the user can see the inside of the first passage 1101 with his line of sight directed toward the first passage 1101. The second lens barrel portion 111 also has a second channel 1111 formed in the longitudinal direction, and the user can see the inside of the first channel 1101 with his/her line of sight directed toward the second channel 1111. That is, the face of the user is located at a position where the eyeball can be brought close to the second channel 1111.

A portion of the first barrel portion 110 including one end thereof can be inserted into the second channel 1111 to move along the second channel 1111. At this time, the inner circumferential surface of the second channel 1111 may be formed with a protrusion part 1112 protruding inward. The protrusion 1112 is a member for restricting the insertion of the first lens tube portion 110, and prevents the first lens tube portion 110 from being unnecessarily inserted into the second channel 1111, thereby preventing damage to the shutter portion 140 and the eye tracker portion 150, which will be described later.

The cover portion 120 is a member that opens or closes the first passage 1101, and is located at the other end of each first barrel portion 110. The cover part 120 may include: a blocking member 121 having the same or larger diameter as the first passage 1101; and a first moving member 122 having a bar shape, coupled to one surface of the blocking member 121, and formed with gear teeth at one portion.

At this time, the first barrel portion 110 is formed with a groove 1102, and the groove 1102 prevents a gap from being generated between the first passage 1101 and the cover portion 120 in accordance with the shape of the first moving member 122 protruding from one surface of the blocking member 121.

The cover adjusting part 130 is a member that adjusts the positions of the pair of cover parts 120 by forward rotation or reverse rotation, and includes a motor 131, a rotating shaft 132 (see fig. 3) coupled to the motor 131, and a motor gear 133 coupled to the rotating shaft 132. The motor gear 133 may be engaged with gear teeth formed at the first moving member 122. At this time, the pair of cover parts 120 are disposed such that the portions of the first moving member 122 where the gear teeth are formed face each other, one cover part 120 is disposed such that the first moving member 122 is located at the lower portion, and the other cover part 120 is disposed such that the first moving member 122 is located at the upper portion, and is engaged with the motor gear of the cover adjusting portion 130. That is, one cover adjusting portion 130 engages with the two covers 120, and the first passage 1101 is opened or closed simultaneously by forward rotation or reverse rotation of the cover adjusting portion 130.

The opening and closing of the first channel 1101 by the cover adjustment portion 130 and the cover 120 will be described in more detail with reference to fig. 4. Fig. 4 a is a rear view showing a state where the cover portion 120 closes the first passage 1101 of the first barrel portion 110, and fig. 4 b is a rear view showing a state where the first passage 1101 of the first barrel portion 110 is opened by the cover portion 120. The first moving member 122 of one cover part 120 is engaged with the upper part of the motor gear 133, and the other cover part 120 is engaged with the lower part of the motor gear 133.

By the forward rotation of the motor gear 133, the pair of lid portions 120 located on the same line as the first lens barrel portion 110 can move toward the lid adjustment portion 130, thereby opening the first lens barrel portion 110. By the reverse rotation of the motor gear 133, the pair of lid portions 120 located on the lid adjustment portion 130 side can move toward the respective first lens barrel portions 110, thereby closing the first lens barrel portions 110.

According to an embodiment of the present invention, the blocking member 121 may have a hemispherical groove 1211 formed on an outer circumferential surface thereof. The groove 1211 is used to prevent the blocking member 121 from being moved when the lid 120 moves toward the lid adjustment portion 130 and thus the first channel 1101 cannot be completely opened due to the blocking of the protruding rotation shaft 132. In other words, even when the space between the pair of first lens barrel portions 110 is narrowed by moving the blocking member 121 to the cover adjustment portion 130 side to the maximum, the first path 1101 can be completely opened.

The slot 1211 is the same size as the axis of rotation 132, and preferably is larger than the axis of rotation 132, and the slot 1211 is sized such that the first channel 1101 is not visible when the first channel 1101 is closed. At this time, the first moving member 122 is formed on one surface of the blocking member 121, the first moving member 122 of any one of the two cover parts 120 is positioned at the lower portion, and the first moving member 122 of the other cover part 120 is positioned at the upper portion, so that the first moving members 122 do not collide with each other when moving to the motor gear side of the cover adjusting part 130.

According to an embodiment of the present invention, the motion part 10 may further include a shutter part 140, an eyeball tracking part 150, a light emitting part 160, a display part 170, a focus adjustment part 180, and an interval adjustment part 190.

The shutter portion 140 adjusts the amount of light passing through the inside of the second channel 1111, and is coupled to the second channel 1111. The control part 40 controls the shutter part 140 so that the light passes through the second channel 1111 to the maximum, or the light entering the second channel 1111 is blocked from passing.

When the light passes through the shutter portion 140 to the maximum, the iris muscle of the user becomes relaxed. When the light passing through the shutter portion 140 is blocked, the iris muscle of the user is contracted. That is, the control unit 40 adjusts the shutter unit 140 to provide the iris movement pattern. At this time, the light passing through the shutter portion 140 may be light generated by the light emitting portion 160 or light entering from the external environment.

When the control unit 40 provides the user with a motion mode other than the iris motion mode, the shutter unit 140 is controlled to be kept in the maximally opened state so that the motion is not hindered by the shutter unit 140. Alternatively, the shutter section 140 may be an electronic shutter using a transparent lcd (liquid Crystal display) panel.

The eyeball tracking portion 150 is a member that captures the movement of the eyeball of the user, and is coupled to the second channel 1111 of the second lens barrel portion 111. The eye tracking unit 150 captures the eye movement of the user and transmits the captured eye movement to the control unit 40. The control unit 40 calculates a training method, a training time, and the like based on the received eye movement. Wherein the training time may be a training time until the user can recover 1.0 or more vision. According to an embodiment of the present invention, the control unit 40 may control the later-described interval adjustment unit 190 according to the position of the eyeball tracked by the eyeball tracking unit 150.

The light emitting unit 160 is a light emitting member, and a plurality of light emitting units are coupled along the inner circumferential surface of the first channel 1101. The Light Emitting unit 160 may be formed of Light Emitting Diodes (LEDs), Organic Light Emitting Diodes (OLEDs), or the like, and may be turned on or off according to a command from the control unit 40 to adjust the illuminance. The user moves the eyeball according to the light-emitting portion 160, and the rectus muscle and the oblique muscle are lifted. That is, the control unit 40 controls the light emitting unit 160 to provide the user with the rectus muscle and oblique muscle movement patterns.

The display unit 170 is a member for providing a visual image to the user, and displays an image for instructing or guiding the movement of the eyeball according to a signal from the control unit 40. In the case of providing the iris movement pattern using light in the external environment, in order to prevent the display part 170 from blocking the entrance of light, the display part 170 is coupled to one surface of the cover part 120 so as to move together with the cover part 120 when the cover part 120 moves. The Display unit 170 may be formed of a Liquid Crystal Display (LCD), an Organic Light Emitting Diode (OLED), an Active Matrix Organic Light Emitting Diode (AMOLED), or the like.

The focus adjustment unit 180 is a member that adjusts the degree of insertion of the first lens barrel portion 110 inserted into the second lens barrel portion 111 to adjust the focus, and includes a motor, a rotating shaft coupled to the motor, and a motor gear coupled to the rotating shaft. At this time, a rod-shaped second moving member 112 is coupled in parallel to the outer peripheral surface of the first lens barrel portion 110, and gear teeth are formed on one surface of the second moving member 112. The motor gear of the focus adjustment portion 180 is engaged with the pair of second moving members 112, and the pair of first lens barrel portions 110 are simultaneously inserted into or projected from the second lens barrel portions 111 by the forward rotation or reverse rotation of the focus adjustment portion 180. By adjusting the focus, the crystal is thickened and thinned and is repeatedly trained, so that the flexibility of the crystal is improved.

The interval adjusting part 190 is a member that adjusts an interval between the pair of second lens barrel parts 111, and may include a rotating shaft coupled to a motor and a motor gear coupled to the rotating shaft. At this time, a rod-shaped third moving member 113 is coupled to the outer peripheral surface of the second lens barrel portion 111 perpendicularly to the second lens barrel portion 111, and gear teeth are formed on one surface of the third moving member 113. The motor gear of the interval adjustment part 190 is engaged with the gear teeth formed at the pair of third moving members 113, and the pair of second barrel parts 111 are simultaneously moved by the forward rotation or reverse rotation of the motor of the interval adjustment part 190, so that the interval between the second barrel parts 111 is narrowed or widened. The interval between the pair of second barrel portions 111 can be narrowed or widened within a certain range. The massage unit 20 will be described in more detail with reference to fig. 2 and 5.

Fig. 5 is a front view of the massage part 20 of the eye movement apparatus 1 according to the embodiment of the present invention. The massage part 20 is a member that presses the periphery of the eyeball of the user and provides a warming function. The massage part 20 may be coupled to one surface of the housing 100 enclosing the moving part 10, and includes a contact part 200 and a protrusion part 210.

The contact portion 200 has a shape corresponding to the shape of the face of a human body, and a see-through hole 201 is formed at a position where an eyeball of a user is located. Since the contact portion 200 directly contacts the body of the user, a natural resin or a synthetic resin capable of preventing the generation and propagation of bacteria is preferably used. One or more protrusions 210 are formed along the circumference of the see-through hole 201 formed in the contact portion 200 to press the circumference of the user's eye.

According to an embodiment of the present invention, the circumference of the see-through hole 201 of the contact part 200 may form a concave groove 202, and the protrusion part 210 is inserted into the concave groove 202 and a portion protrudes to the outside of the concave groove 202. At this time, the lower end of each protrusion 210 may form a height adjustment part 220 for adjusting the protrusion degree of the protrusion 210.

Also, according to an embodiment of the present invention, the lower end of the height adjuster 220 may further include a movement adjuster 230 that causes the protrusion 210 to move along the recess groove 202. The height adjusting parts 220 are provided at the movement adjusting part 230 with a certain interval, and rotate together with the rotation of the movement adjusting part 230.

Although not shown in the drawings, a hot wire may be formed inside the contact portion 200 and connected to the control portion 40 to generate heat according to a signal of the control portion 40.

The input part 30 is a member that receives a command signal for controlling the user of the motion part 10 or the massage part 20 and transmits it to the control part 40. The input unit 30 is preferably constituted by a touch panel (touch panel), and may be constituted by a button key (button key), a stick key (jog key), a wheel key (wheel key), or the like. In the present invention, the input part 30 receives a massage execution command, a motion pattern execution command, a specific motion pattern execution command, and the like from the user and transmits them to the control part 40. Wherein the motion mode execution command is a command to execute a plurality of motion modes in a preset order, and the specific motion mode execution command is a command to execute only one motion mode among the plurality of motion modes. That is, the control unit 40 controls the motion unit 10 to provide the motion patterns in a preset order when receiving the motion pattern execution command from the user through the input unit 30, and controls the motion unit 10 to provide the selected specific motion pattern when receiving the specific motion pattern execution command from the user through the input unit 30.

According to an embodiment of the present invention, the eye movement device 1 may further include an illuminance measurement section 50 and a proximity sensor section 60. The illuminance measuring unit 50 measures illuminance and transmits the measured value to the control unit 40, and is coupled to the other surface of the cover 120 to measure illuminance of the external environment. The proximity sensor unit 60 measures the proximity of an object approaching a predetermined detection surface or an object existing near the detection surface, and transmits the measured proximity to the control unit 40, and is coupled to one surface of the contact unit 200 to detect whether or not the user uses the eye movement device 1.

The control unit 40 controls the motion unit 10 and the massage unit 20 to perform a data processing function. In the present invention, the control unit 40 controls the massage unit 20 or the motion unit 10 according to a command input through the input unit 30. More specifically, the control unit 40 can operate the height adjustment unit 220 and the movement adjustment unit 230 upon receiving the massage execution command from the input unit 30. Upon receiving the exercise mode execution command, the control unit 40 controls the exercise unit 10 to provide a plurality of exercise modes in a predetermined order. Upon receiving the specific exercise mode execution command, the control unit 40 controls the exercise unit 10 to provide only the selected specific exercise mode.

When the illuminance received from the illuminance measuring unit 50 is equal to or greater than the preset illuminance value, the control unit 40 controls the cover adjusting unit 130 to open the first channel 1101. That is, when the external environment is equal to or higher than the preset illuminance, the control unit 40 determines that the iris movement pattern can be provided by the light of the external environment without using the light emitting unit 160, and therefore opens the cover adjustment unit 130.

The control part 40 may suspend the operations of the moving part 10 and the massage part 20 when the proximity measurement value received from the proximity sensor part 60 is less than a preset proximity value. That is, it is determined that the user is not using the eye movement apparatus 1, and the power of the eye movement apparatus 1 is turned OFF (OFF). According to an embodiment of the present invention, when the proximity measurement value received from the proximity sensor part 60 is above a preset proximity value, the control part 40 determines that the user is using the eye movement device 1, thereby turning ON (ON) the power of the eye movement device 1. At this time, the preset proximity value may be set within a range, and at this time, if the proximity measurement value is smaller than the minimum value of the range, the power of the eye movement device 1 is turned OFF (OFF), and if the proximity measurement value exceeds the maximum value of the range, the power of the eye movement device 1 is turned ON (ON).

When receiving the movement pattern execution command or the specific movement pattern execution command from the input section 30, the control section 40 activates the eye tracking section 150 and controls the interval adjustment section 190 according to the position of the eye first received from the eye tracking section 150. That is, the control unit 40 can adjust the position of the second lens barrel portion 111 according to the eyeball position of the user.

According to an embodiment of the present invention, the housing 100 of the eye movement apparatus 1 is formed in an empty box shape, and a through hole 101 is formed on one surface of the housing adjacent to the lid portion, and a through hole may be formed on a surface horizontal to the one surface. That is, the other end of the first barrel portion and the one end of the second barrel portion are not blocked by the housing 100. Fig. 6 shows a specific structure of the inside of the housing 100 visible through the through-hole 101. A slide groove 102 is formed on a surface perpendicular to a surface of the housing 100 on which the through hole 101 is formed, and a slide rod 103 (see fig. 6) coupled to the slide groove 102 is further provided. The slide bar 103 is inserted into the slide groove 102 to move along the slide groove 102.

The slide bar 103 includes a bar-shaped insertion member 1031 inserted into the slide slot 102 and a fixing member 1032 vertically coupled to one end of the insertion member 1031. The fixing member 1032 is used to fix the focus card 104, and may be a clip-shaped or plate-shaped adhesive pad. At this time, the focus card 104 is a card for confirming binocular vision of both eyes, and the user can confirm whether the user is strabismus or anisometropia using the focus card 104. The focus card 104 is described in more detail with reference to fig. 7.

Fig. 7 is a front view of the focus card 104 of the eye movement apparatus 1 according to the embodiment of the present invention. The focus card 104 may be symmetrical in image as in a of fig. 7. If a normal person fixes the focus card 104 to the fixing member 1032 of the slide bar 103 and then observes the focus card 104 of a through the second channel 1111 and the first channel 1101, both eyes are visually fused and recognized as the focus card 104 of b. A user who cannot recognize the form of the focus card 104 of b has strabismus or unequal vision.
