Prior cases for electronic spectacles can be less than ideal in at least some respects. Electronic spectacles (hereinafter “eSpecs”) are spectacles that use electronics to provide images to an eye of the wearer. Electronic spectacles may be used to provide simulation to a patent's eyes, such as to the retina, to treat refractive errors of the patient's eyes. Prior electronic cases for charging spectacles can be less than ideal for a number of reasons. The prior electronic cases may not provide for easy charging and monitoring of the status and usage of electronic spectacles associated with the electronic cases. This may result in problems, such as a patient's failure to use the electronic spectacles, premature energy depletion in the electronic spectacles, poor tracking of the patient's compliance with a prescribed amount of stimulation, and other issues.
The electronic case disclosed herein, and the disclosed method of assembly and use with electronic spectacles, provide for an electronic spectacle case comprising components that can be configured in many ways and may comprise one or more of display and indicator components, user interface components, programming components, monitoring components, and power components. In some embodiments, the programming components of the case are used to configure the stimulation provided by the electronic spectacles. In some embodiments, the monitoring components receive or read information from the electronic spectacles to determine the patient's use and compliance with treatment and may transmit this information to a medical provider or display a summary of the information using indicator components. The programming and monitoring components provide more accurate control of the stimulation and monitoring of patent's use.
Protection of the electronic spectacles is also improved. By providing a case for charging and programming the electronic spectacles, the spectacles may remain in a protective environment during charging, programming, and monitoring. Thereby, reducing the risk of accidental damage to the electronic spectacles.
An electronic case for electronic spectacles may include a base comprising a cavity formed therein. A first spectacle retention device may be located within the cavity. The first spectacle retention device may be configured to retain spectacles. An electrical control system may be included. An electrical connector may be configured to couple the electrical control system in electronic communication with the spectacles.
An electronic case for electronic spectacles may include a processor and a non-transitory computer readable medium configured with instructions that when executed by the processor cause the processor to perform operations. The operations may include receiving spectacle stimulation configuration data, transmitting the spectacle stimulation configuration data to the electronic spectacles, receiving patient stimulation data from the electronic spectacles, and indicating patient compliance based on the received patient stimulation data.

The power indicator 130 may provide visual indication of the amount of energy remaining in an energy storage device within the case 100. In some embodiments, the power indicator 130 may include one or more sub indicators. The indicator 130 or the sub indicators may include a light guide positioned on the rim of the case and a light source such as an LED associated with each of the light guides. In the example shown in
In some embodiments, the indicators may have a plurality of functions. For example, in order to indicate that the energy storage device, such as a battery or capacitor, is charging and has less than one third of its total capacity, a single indicator or sub indicator may be blinking whereby its illumination is cycled on and off periodically such as a period of 1 Hz. Similarly, if the single indicator is illuminated and a second indicator is blinking, then the energy storage device may be charging and have a charge state of between one third and two thirds its total capacity. Finally, if two indicators are illuminated and a third indicator is blinking, then the energy storage device may be charging and have a charge state of greater than one third of its total capacity.
In some embodiments, the power indicator 130 may shaped such that indicator is viewable when the case is open, for example, when the lid is rotated away from the base, and when the case is closed, for example, when the lid is rotated over the base. In some embodiments, the power indicator 130 may include light guides with more than one illuminated surface. For example, in some embodiments, the light guides of the indicator 130 may include a first surface that faces a first direction that is covered by the lid when the lid is closed, and a second surface that faces a second direction that is not covered by the lid when the lid is in the closed position. In some embodiments, the first direction may be along the height direction and the second direction may be a direction outward from the perimeter of the case 100. In some embodiments, an angle between the first direction and the second direction may be less than 90 degrees.
The case power indicator 130 may interface with a processor of the case that reads the charge status of the energy storage device, including both remaining capacity and whether or not the energy storage device is currently being charged. The processor illuminates the case power indicator 130 appropriately based on the charge status of the energy storage device.
In some embodiments, the case 100 may include a spectacle power indicator, such as spectacle power indicator 132. The spectacle power indicator 132 may provide visual indication of the amount of energy remaining in an energy storage device within the spectacles 400. In some embodiments, the spectacle power indicator 132 may include one or more sub indicators. The indicator 132 or the sub indicators may include a light guide positioned on the rim of the case and a light source such as an LED associated with each of the light guides. In the example shown in
In some embodiments, the spectacle power indicator may have a plurality of functions. For example, in order to indicate that the energy storage device, such as a battery or capacitor within the spectacles, is charging and has less than one third of its total capacity, a single indicator or sub indicator may be blinking whereby its illumination is cycled on and off periodically such as a period of 1 Hz. Similarly, if the single indicator is illuminated and a second indicator is blinking, then the energy storage device may be charging and have a charge state of between one third and two thirds its total capacity. Finally, if two indicators are illuminated and a third indicator is blinking, and the energy storage device may be charging and have a charge state of greater than one third of its total capacity.
In some embodiments, the power indicator 132 may be shaped such that indicator is viewable when the case is open, for example, when the lid is rotated away from the base, and when the case is closed, for example, when the lid is rotated over the base. In some embodiments, the power indicator 132 may include light guides with more than one illuminated surface. For example, in some embodiments, the light guides of the indicator 132 may include a first surface that faces a first direction that is covered by the lid when the lid is closed, and a second surface that faces a second direction that is not covered by the lid when the lid is in the closed position. In some embodiments, the first direction may be along the height direction and the second direction may be a direction outward from the perimeter of the case 100. In some embodiments, an angle between the first direction and the second direction may be less than 90 degrees.
In some embodiments, the case power indicator 132 may interface with a processor of the case that reads the charge status of the energy storage device of the spectacles via the connector 124. The charge status may include both remaining capacity and whether or not the energy storage device is currently being charged. The processor may then illuminate the spectacle power indicator 132 appropriately based on the charge status of the energy storage device. In some embodiments, the processor may read the charge state of the battery directly via the power connections in the connector 124. In some embodiments, the processor of the case may communicate with a processor or memory of the spectacles 124 and receive the charge state information from the processor or memory of the spectacles.
In some embodiments, the case 100 may include a compliance indicator 144. Compliance is a measure of the extent to which the patient's behavior matches the doctor's recommendations or prescription. The compliance indicator 144 may display or otherwise indicate how well a patient is complying with their prescribed or programmed treatment. The prescribed program treatment may be input into the case in many ways. For example, as discussed elsewhere herein, the case may include a programming interface whereby a user can adjust usage settings for the spectacles. In some embodiments, the spectacles in the case may be programmed through other means, such as for wirelessly as described elsewhere herein.
The spectacles may record their use. In some embodiments, the spectacles may record the amount of time the spectacles are worn by the patient and turned on to provide stimulation to the patient's eyes. In some embodiments, the spectacles may automatically turn off after their prescribed or programmed amount of stimulation is applied. In some embodiments, the spectacles may store in memory the amount of time they have provided stimulation to a patient's eye. When the spectacles are placed back in the case after use and connected to the case via the electrical connection 124, the circuitry within the case, such as its processor, may access memory and/or the processor within the spectacles to read or otherwise receive the patient usage data stored within the spectacles. The retrieved usage data may be compared to the prescribed or programmed stimulation and an amount of compliance may be determined, such as determining a percentage of compliance by dividing the recorded stimulation provided by the spectacles by the prescribed or programmed stimulation.
The amount of stimulation may be prescribed based on a single day usage, weekly usage, monthly usage, or usage over other time frames. For example, the stimulation may be prescribed or programmed as four hours of stimulation every day. If the patient received at least the prescribed or programmed amount of stimulation, such as four hours of stimulation, then compliance is considered to be 100%. If the patient has received less than the prescribed or programmed amount of stimulation, such as three hours of stimulation, and the patient has 75% compliance. This compliance information may be displayed on the compliance indicator 144.
In some embodiments, the compliance indicator 144 may include one or more sub indicators. The compliance indicator 144 or the sub indicators may include a light guide positioned on the rim of the case and a light source such as an LED associated with each of the light guides. In the example shown in
In some embodiments, the indicators described herein may have more or fewer sub indicators and their illumination may indicate a corresponding fraction of the amount of compliance, energy, or other data. For example, with 10 sub indicators each indicator represents 10% compliance or energy.
The compliance indicator and the measurement of patient compliance may be based on an internal calendar or other time measuring means within the case or the spectacles. In some embodiments, the compliance indicator may measure compliance over a manually reset interval. In some embodiments, the case may include a button 140 for resetting the compliance interval. During use, when the compliance button 140 is pressed, the currently recorded amount of compliance is reset to zero. The spectacles may then begin recording the accumulated amount of stimulation provided to the patient by the spectacles.
After at least some use by the patient, the patient may place the spectacles back into the case and connect the spectacles to the electronic connector 124, after which the case may read or otherwise received the usage data from the spectacles and display the amount of compliance on the compliance indicator 144. If the patient is not fully complied with the prescribed or programmed stimulation, then the patient may take the spectacles out of the case and wear them for additional time and later place them back into the case at which time the compliance indicator may again indicate an updated amount of compliance. At the end of the day or other compliance measuring period of time, the patient may record the number of illuminated lights or otherwise record the amount of compliance indicated and then may press the compliance button 142 reset the compliance information back to zero.
The case 100 may also include a status indicator 142. The status indicator may be a general-purpose indicator that informs the user of errors or other problems with the case and or the spectacles. For example, in some embodiments, the status indicator 142 may be a multicolor status indicator that may be related in different colors to indicate various statuses to the patient or user. For example, the status indicator may be illuminated to indicate a communication problem between the case and the spectacles, a fault within the memory or processors of the spectacles and/or the case, or other issues. The illumination of the status indicator may indicate that a user should bring the device to the prescribing doctor or assistance.
The indicators described herein may be single color or multicolor. In some embodiments, a single-color LED may be placed below or relative to each indicator or sub indicator and the corresponding light guide in order to illuminate the corresponding portion of the indicator. In some embodiments, a single multicolor LED or a plurality of different colored LEDs may be placed below or relative to each indicator or sub indicator and the corresponding light guide in order to illuminate this corresponding portion of the indicator. In some embodiments, the colors and type of illumination may indicate different statuses to the user. For example, the case power and spectacle power indicators may be a single indicator or set of sub indicators wherein illuminating the sub indicators with a first color indicates the amount of energy remaining in the spectacles while illuminating the indicators with a second color indicates the amount of energy remaining in the case. In some embodiments, an indicator may the illuminated with a third color to indicate compliance. In this way, a single indicator may be used to indicate energy for the spectacles and the case and patient compliance with the prescribed or programmed stimulation.
The main logic board 160 may be arranged in many ways and may include many components. In some embodiments, the main logic board includes a power input and wired communication input such as the electrical connection 166. The electrical connection 166 may be accessible from outside the case 100 after the case is assembled. The electrical connection 166 may be a USB connection, a power connection, a FireWire connection, an ethernet connection, or other serial or parallel communication connection. The logic board 160 may include a processor and non-transitory memory for storing data and instructions that when executed by the processor cause the processor to carry out any of the methods or processes described herein. The main logic board may also include wireless communication components for communicating wirelessly with other devices such as computers, servers, and electronic spectacles 400.
The logic board 160 may also be electrically coupled to the electronic connection 124, discussed above with respect to
The logic board 160 may also include or be electronically coupled to voltage regulators and one or more energy storage devices. For example, the case 100 includes an energy storage device 168, which may be a battery. The battery 168 may be physically and electrically coupled to the logic board 160 and may receive power through the electronic connection 166. The battery may also supply power through the logic board and the connector 124 to the spectacles 400. In some embodiments, the energy storage device 168 may be physically coupled to the base insert 120. As shown in
The interface logic board 162 may be located about or within the rim 121 of the base insert 120. The interface logic board 162 may include input devices and indicators. For example, the interface logic board 162 may include light sources such as LEDs that are used to provide the illumination for the indicators 130, 132, and 144. Interface logic board 162 may also include an input device such as the button 140 for receiving user input. The button 140 may be a momentary tactile switch that is normally open. In some embodiments, a flexible cover may be placed within an aperture of the rim above the button 140, such that the flexible cover deflects as the user presses their finger on the cover which causes the underside of the cover to contact the switch which registers the user's input, such as by resetting the compliance monitor.
The interface logic board 162 may follow the contour and shape of the rim 121 and/or the perimeter of the base insert 120. In some embodiments, the interface logic board may extend along at least one third of the rim 121 and/or the perimeter of the base insert 120. In some embodiments, the interface logic board 162 may be arranged in a plane parallel to the main logic board 160.
For example, in
In some embodiments, a second set of switches 312B may be used to program the recommended or prescribed duration of treatment. In some embodiments, each single switch may be used to indicate the duration of treatment. In some embodiments, only one switch may be in the on position for programming. Table 2 shows one example of the programming for stimulus duration.
In some embodiments, each switch may be used to program a portion of the duration of treatment. The sum of the durations may be added together to determine the total stimulus duration. Table 3 shows examples the programming for stimulus duration.
In some embodiments, after setting the switches in their appropriate state the settings may be transferred to the case and/or the spectacles my pressing a confirmation or programming set button or switch such as button 316. Pressing button 316 may cause the processor may case to read the values of the switches and then program the spectacles 400 with the appropriate stimulation and based on the values of the switches.
In some embodiments, the programming interface may include a status indicator. The status indicators may illuminate in a first color to indicate it is ready to be programmed, a second color to indicate that the case is programmed correctly, such as after the user pressed the programming button 216, and a third color to indicate an error in programming.
In some embodiments, for the treatment of spherical refractive errors of the eye, the plurality of light sources, such as projection units, are arranged with symmetrically with respect to central axis of the spectacle lens, the center of the spectacle lens, or another location of the spectacle lens. The symmetry may be rotational symmetry, such that the light sources are arranged on a circumference centered on the location of the spectacle lens.
In some embodiments, for example, for the treatment of astigmatism, the electronic spectacle 400 is configured to project defocused images with respect to the astigmatic axes of the patient's eye to provide different amounts of stimulation to different regions of the peripheral retina. In some embodiments, the light sources such as projection units are located along the astigmatic axis, although the light sources may be located at other locations. The light sources can be configured to provide different amounts of stimulation to the peripheral retina in accordance with the refractive error of the eye. In some embodiments, the light sources are configured to provide different amounts of illumination along different axes in order to promote different changes in choroidal and scleral tissue corresponding to different changes in axial length as described herein. The spectacle lens may comprise an optical zone configured to correct astigmatic refractive errors in accordance with the first axis and the second axis.
In some embodiments, the spectacle lenses 402 may include an optical zone that can be appropriately sized for the pupil of the eye and the illumination conditions during treatment. The central optical zone is designed to provide emmetropic correction or other suitable correction to the wearer and may be provided with both spherical and astigmatic correction. The central optical zone is circumscribed by an outer annular zone, such as a peripheral zone. The optical zone is configured to provide refractive correction and can be spherical, toric or multifocal in design, for example with a visual acuity of 20/20 or better.
The spectacle lenses 402 includes a plurality of embedded projection units. Each of the plurality of projection units comprises a light source and one or more optics to focus light in front of the retina as described herein. Each of the optics may comprise one or more of a mirror, a plurality of mirrors, a lens, a plurality of lenses, a diffractive optic, a Fresnel lens, a light pipe or a wave guide.
The spectacles 400 may include two temple portions 404. The temple portion of the spectacles may be connected via a hinge 408 to an end piece 406. The end piece 406 couples the hinge to the frame of the lenses 402. The temple piece 404 may include a cavity 402 for housing electrical and control system of the electronic spectacles 400. An electrical connection 410 may be included in the spectacles 400. In some embodiments, the electrical connection 410 may be located on a temple 404 of the spectacles 400. In some embodiments, the electrical connection 410 may be located on a bottom side of a temple 404 of the spectacles 400.

The spectacles component cavity may comprise a battery, microcontroller, processor, memory, including non-transitory memory, and communication circuits, such as wired or wireless communication circuitry and one or more antennae for electronic communication. Although reference is made to a battery, the spectacle may comprise any suitable energy storage device.
The projection units 12 can be configured to provide defocused images to the peripheral portion of the retina as described herein and may include light sources and projection optics. In some embodiments, one or more projection optics are configured with the light sources to project a defocused image from the light sources onto the peripheral retina away from the central visual field that includes the macula in order to stimulate a change in choroidal thickness, such as an increase or decrease in cordial thickness. The one or more projection units can be configured to stimulate the retina without degrading central vision and corresponding images formed on one or more of the foveal or macular regions of the retina. In some embodiments, the one or more projection optics do not decrease the image forming characteristics of the vision correction optics prescribed to correct refractive errors of the wearers. This configuration can allow the wearer to have good visual acuity while receiving therapy from the defocused images as described herein.
In some embodiments, the light from light sources of the projection units is columnated and focused by one or more projection optics, as described herein. The function of the light sources and the projection optics is to substantially collimate the light emitted by the light sources and focus it at a focus that is designed to be in the front of or behind the retina to provide appropriate defocus to stimulate a change in choroidal thickness. For myopic defocus, the focused images may appear approximately 1.5 mm to 2.5 mm in front of the peripheral retina and myopic by about 2.0D to 5.0D, for example 2.0D to 4.0D, or preferably 2.5D to 3.5D, for example. For hyperopic defocus, he focused images may appear approximately 1.5 mm to 2.5 mm behind of the peripheral retina, in order to be hyperopic by about −2.0D to 5.0D, for example −2.0D to −4.0D, or preferably −2.5D to −3.5D, for example.
In accordance with some embodiments, a spectacle 400 comprises projection units which include projection optics and micro-displays as the light source. The micro-displays may comprise an OLED (organic light emitting diode) or an array of micro-LEDs. Light emitted by these displays may be Lambertian. In some embodiments, the micro-display is optically coupled to a micro-optical array that substantially collimates and focuses the light emanating from the micro-display. The micro-display may comprise one or more miniaturized pixels. In some embodiments, the micro-display forms an extended array of pixels, characterized by a pixel size and a pixel pitch, in which the pixel size and the pixel pitch together correspond to a fill factor of the micro-display. As described herein, each of the pixels may have a size within a range from about 2 microns to about 100 microns, and the pixel pitch may range from 10 microns to 1.0 mm, for example. The corresponding fill factor can range from 0.1% to 10%. In some embodiments, the pixel array is optically coupled with a micro-optic array in order to substantially collimate and focus light from the pixels.
The images created by these displays is defocused and may be placed symmetrically in four quadrants of the field of view or of the eye (e.g. nasal-inferior, nasal-superior, temporal-inferior and temporal-superior). The micro displays can be located away from the optical center of the lens. The central optic of the lens can be selected to bring the wearer to emmetropia. Each micro-display may be circular, rectangular or arcuate in shape and have an area within a range from 0.01 mm2 to 8.0 mm2, for example within a range from 0.04 mm2 to 8.0 mm2, for example within a range from 1 mm2 to 8 mm2, or preferably within a range from 1.0 mm2 to 4.0 mm2, in some embodiments.
The micro-display can be coupled to and supported with the body of the correction optic such as the spectacle lens, for example.
