Abstract

An electronic image shown on a display can be shifted to the left for left eye viewing and shifted to the right for right eye viewing. A left shutter can be positioned over the left eye and a right shutter positioned over the right eye. The left shutter can open when the image shown on the display is shifted to the left, and the right shutter can open when the image shown on the display is shifted to the right, such that each eye can view the image without substantial convergence. In addition to relieving convergence, embodiments of the present invention may relieve prolonged ciliary muscle spasms that can result in pseudomyopia, and may also decrease the onset and severity of myopia, for example developmental myopia.

Description

System for reducing eye convergence when viewing electronic images on a display

This creation generally involves the reduction of eye convergence. Embodiments of the present invention provide methods and apparatus for preventing and treating myopia caused by prolonged use of a computer display, computer games, and watching television. While the reduction of eye convergence is specifically raised with electronic images on the display, embodiments of the present writing can be applied to other images as well as other displays.

Displays exist in many places and are widely used. For example, displays are used with computers, video games, home theaters, telephones, and televisions. In many cases, it may be desirable to place the display close to the user. The proximity of the display to the user enables the image displayed on the display to be presented to the user more, such as a computer and video display that is typically about one meter or less from the user.

While it is advantageous to place the display close to the user, this can also have the disadvantage of not being fully correctable in many cases. Due to the eye The crystal of the eye can be adjusted to focus the display, so many people who can adjust with the crystal of the eye can easily see the display at close range. However, long-term adjustment of the eye can cause functional myopia, or nearsightedness. Since accommodation reflex (hence, called close-range response or adjustment response) occurs when a person watches a close object, it may be difficult, and in some cases practically impossible, to avoid contraction of the ciliary muscle. Until a person focuses on close-up objects, close-up objects include computer monitors, computer games, and television.

Work related to the embodiments of the present creation suggests that long-term use of computer monitors, computer games, and televisions can cause myopia. For example, prolonged use of a close-up display may cause ciliary muscle spasm, which causes functional myopia, allowing the user to have nearsightedness when the sputum continues, even when viewing distant objects. In addition, long-term viewing of close-up displays and associated ciliary tendons can play a role in the development of permanent myopia, for example, developmental myopia in adolescents.

In view of this, it would be desirable to provide methods and/or apparatus for viewing objects such as displays that avoid at least some of the above disadvantages.

Possible related patents and patent applications include U.S. Patent Nos. 6,709,101, 6,347,869, 5,204,702, 3,883,225; U.S. Patent Publication No. 2005/0213035; and EP 0362692.

This creation generally relates to the reduction of eye convergence, and more particularly to eye fatigue associated with display devices. Embodiments of the present invention provide methods and apparatus for preventing and treating myopia caused by prolonged use of a computer display, computer games, and watching television. Although an electronic image on the display is specifically proposed, embodiments of the present creation can be applied to other images as well as other displays. In some embodiments, the electronic image shown on the display moves to the left for left eye viewing and to the right for right eye viewing. The left shutter can be placed on the left eye and the right shutter can be placed on the right eye. When the image shown on the display moves to the left, the left shutter can be opened, and when the image shown on the display moves to the right, the right shutter can be opened so that each eye can view the image without substantial Convergence. In addition to mitigating convergence, embodiments of the present creation can alleviate, or at least reduce, prolonged ciliary muscle spasm that can cause pseudomyopia. Thus, in addition to reducing eye convergence and associated eye fatigue and overwork, certain embodiments of the present invention may also reduce the onset or exacerbation of myopia, such as developmental myopia.

In a first aspect, embodiments of the present disclosure provide a method for reducing eye convergence when viewing an electronic image on a display (eg, a projection display, a computer screen, or a video game screen). The electronic image is moved horizontally on the display according to a time mode, for example, a video picture playback rate. According to the time mode, the left and right eyes of the display are alternately viewed. For each eye, the distance is sufficient to view the image without substantial convergence.

In many embodiments, the time mode is constant. In special In a given embodiment, the image is moved at a rate and the rate ranges from 30 Hz to 120 Hz. In a particular embodiment, the preselected distance includes a range and this range is from 0.1 cm to 5 cm.

In some embodiments, the liquid crystal shutter can be energized and de-energized to open and close the shutter worn on each eye. In some embodiments, the mechanical shutter can be opened and closed to open and close the shutter worn on each eye.

In many embodiments, the image movement distance includes a preselected distance, such as a preset distance. In some embodiments, the image movement distance may correspond to a distance selected by the user. For example, the selected distance can be perceived by the user and selected in response to user comfort. In a particular embodiment, the image movement distance can be incrementally increased to a maximum distance for which the user perceives the image as a single image. Thus, while a range of distances can provide mitigation, the maximum distance can be selected in response to user perception.

In many embodiments, the image moves to the left when viewed with the user's left eye, and the image moves to the right when viewed with the user's right eye. In order to view with each eye, the magnification of the image can be reduced by a certain amount, and the amount of image magnification reduction can be the same for each eye. In order to view with each eye, the magnification of the image can be reduced to reduce the size of the image on the display, and when the image is moved for viewing on the display with each eye, the image Will not be cut cut.

In another aspect, a system for reducing eye convergence when viewing an electronic image on a display is provided. The system includes electronic circuitry for receiving an electronic image and producing an output of a series of frames including the image. Depending on the time mode, the frame alternately shifts right to left and left to the preselected distance on the display. For each eye, the distance is sufficient to view the image without substantial convergence. The left and right shutters are configured to alternately open and close according to the time mode.

In many embodiments, the display is connected to receive an output of the electronic circuit. The signal source can be connected to supply an electronic image to the electronic circuit.

In many embodiments, the electronic circuit generates timing signals that are coupled to the left and right shutters. The timing signal can be coupled by a line. In some embodiments, the timing signal is wirelessly coupled from the electronic circuit to the left and right shutters.

In many embodiments, the time mode is constant. The image can be moved at a rate ranging from 30 Hz to 120 Hz. The preselected distance ranges from 0.1 cm to 5 cm.

In many embodiments, the preselected distance is selectable by the user via the input device and the electronic circuit is configured to adjust the preselected distance in response to the input device. In some embodiments, the electronic circuitry can be configured to display frames that are alternately shifted right and left on the display to enable the user to select a distance. In a particular embodiment, the electronic circuit is configured to incrementally increase the distance to a maximum distance at which the user will The image is perceived as a single image.

In many embodiments, the electronic circuitry is configured to open and close a shutter worn on each eye to alternate left eye and right eye vision. In some embodiments, the left and right shutters comprise a liquid crystal shutter that is configured to open and close in response to a timing signal. In some embodiments, the left and right shutters include a mechanical shutter that is configured to open and close in response to a timing signal.

In many embodiments, the system includes a frame that is configured to be worn by a user, and the left and right shutters are mounted on the frame. In certain embodiments, the system includes a left side lens and a right side lens, and each lens is coupled to the frame to correct the user's vision.

Embodiments of the present creation can provide eye relief and eye strain relief associated with display devices. Although an electronic image on the display is specifically proposed, embodiments of the present creation can be applied to other images and others monitor. In some embodiments, on the display, for example, an electronic image displayed on the display moves to the left for left eye viewing and to the right for right eye viewing. The left shutter can be placed on the left eye and the right shutter can be placed on the right eye. The left shutter can be opened when the image shown on the display moves to the left, and the right shutter can be opened when the image shown on the display moves to the right so that each eye can view the image without substantial convergence. In addition to mitigating convergence, embodiments of the present creation can alleviate, or at least reduce, prolonged ciliary muscle spasm that can cause pseudomyopia. Thus, in addition to reducing eye focus based on associated eye fatigue and fatigue, certain embodiments of the present disclosure may also reduce the onset or exacerbation of myopia, such as developmental myopia.

Embodiments of the present disclosure provide a reduced near vision response to a target in the vicinity of the patient. The close-range visual response includes a triple response, or a triad, in which the human eye converges, the crystals of both eyes adjust, and the pupils of both eyes contract. According to certain embodiments of the present creation, the triplets shown below are made with reference to an emmetropic eye. An eye with optical correction can act in a similar manner to the eye shown in the front view, for example, glasses with eyes, lenses for contact lenses, and surgically corrected eyes with refractive errors. Moreover, according to certain embodiments of the present creation, an eye with certain refractive errors can respond to near-distance visual stimuli in a manner similar to a legitimate eye.

Figure 1A shows binocular viewing of a distant target. The first eye, or the right eye 110A, and the second eye, or the left eye 110B, are shown as parallel structures. The line of sight 112A from the eye 110A to the distant target is parallel to the slave Eye 110B to line of sight 112B of the distant target. The binocular viewing of such a distant target is associated with the relaxed state of the eye 110A and the eye 110B.

FIG. 1B shows binocular convergence in response to a close range target 130. The right eye 110A and the left eye 110B gaze at the close range target 130 such that the line of sight 112A and the line of sight 112B intersect the target 130 at an angle 132. The close range target 130 can be located on the display 160. The right eye 110A and the left eye 110B are separated by an interpupillary distance (IPD) 114, or an IPD. The right eye 110A and the left eye 110B are spaced apart from the display 160 by a distance 134.

Figure 1C shows the anterior segment of the eye 110 in a relaxed state in response to the distant target as in Figure 1A. Eye 110 includes a cornea 112, an iris 120, and a crystal 114. The iris 120 defines a pupil 122 through which light passes to be refracted by the lens 114. Since the cornea 112 includes a curved surface, the cornea 112 and the lens 114 provide optical power and refracted light to form an image of the target 130 on the retina. Eye 110 includes a ciliary muscle 116. In the relaxed state of regulation, the ciliary muscle 116 relaxes.

FIG. 1D shows the adjustment of the eye in FIG. 1C in response to the close target in FIG. 1B. The ciliary muscle 116 contracts in response to the close target 130 and changes the crystal 114 to provide an adjustment of the focus of the image of the target formed on the retina. The contraction of the ciliary muscle 116 moves the outer circumference of the crystal 114 inward as indicated by arrow 118. The front surface of the crystal 114 moves forward, while the rear surface of the crystal 114 moves rearward as indicated by arrow 119. Therefore, the crystal 114 is thicker and the curvature is increased, thereby increasing the refractive power of the crystal 114 and ensuring that the close target is properly focused on the retina.

Figure 1E shows the relaxation state of the eye as in Figure 1C. Pupil 122. As mentioned above, the pupil 122 is defined by the iris 120.

FIG. 1F shows the pupil contraction pupil 122 of the eye 110 in the state of FIG. 1D. The bore 122 becomes smaller and contracts to compensate for structural changes in the crystal 114. Work on embodiments of the present work suggests that pupil contraction limits light passage to ensure proper use of thickened crystals.

Figure 1G shows pseudo myopia that can be caused by a long response to a close range target as in Figure IB. Prolonged short-term responses can cause ciliary muscle spasm, causing pseudomyopia, or functional pseudomyopia. Light rays 130 are shown entering the eye 114 from a distant target in a parallel arrangement. Eye 114 includes a retina 140. The crystal 114 remains in the adjusted state of pupil contraction, as described above. Thus, light 130 reaches focus 132 before retina 140, or the smallest blurred circle, consistent with myopia. The work on the embodiment of the present work proposes that false myopia can be reduced or even eliminated by moving the position of the object seen by each eye such that the object appears to be away from the user.

1H shows a schematic diagram of a system 150 that responds to inhibition modulation of brachytherapy in accordance with an embodiment of the present disclosure. System 150 includes a right side shutter 150A located before the user's right eye 110A and a left side shutter 110B positioned before the left eye 110B. Display 160 includes a screen showing left side close range target 130A and right side close range target 130B. The display 160 alternately shows the right close target 130A and the left close target 130B. When the right close target 130A is shown on the display 160, the right shutter 150A is open, and when the left close target 130B is shown on the display 160, the right shutter 150B is open. Although as an example, a close target is proposed 130, right close target 130A and left close target 130B, but system 150 can function with many visual stimuli, including video frames, video images, computer generated video and images, letters, characters, and the like. The right eye 110A and the left eye 110B separate the pupil spacing 114. In many embodiments, the information contained in each of the right close target 130A and the left close target 130B may be substantially similar, for example, the same. In many embodiments, each close range target can move the object to subjectively see or perceive and comfortably see the maximum distance of a single target. The left eye 110A and the left eye 110B are spaced apart from the screen by a distance 134, for example, 0.5 meters. In some embodiments, myopia correction, such as +2D correction, may also be provided to enable the target to focus on the retina without requiring a strong adjustment.
