DETAILED DESCRIPTION OF SOME OF THE EMBODIMENTS
Accordingly, some embodiments of the present disclosure are directed to a low-profile, wearable apparatus that includes one or more (e.g., a plurality, and in some embodiments, all) of the following capabilities:

    
    
        low light vision enhancement
        wide dynamic range
        contrast enhancement
        digital zoom
        optical zoom
        dynamic range scaling
    
    


In some embodiments, the general form of some of the embodiments disclosed herein may be similar to that of traditional eyewear (e.g., spectacles, sunglasses, or reading glasses), except that the apparatus may include low light vision enhancing and/or additional vision enhancing capabilities. In some embodiments, the profile of the apparatus may be minimized in terms of its size and shape, e.g., such that the apparatus appears similar to if not indistinguishable from traditional eyewear. This is generally in contrast to night-vision goggles and other existing, bulky low-light vision enhancing products.
For example, in some embodiments, the apparatus may be sized and configured such that, from the bridge of the wearer's nose, the apparatus does not protrude further than 3 inches, further than 2 inches, or further than 1 inch, from the bridge of the wearer's nose (e.g., the apparatus protruding between 1-2 inches or between 1-3 inches from the wearer's nose). In some embodiments, the apparatus may include two sidearms, which may be of the same or similar dimensions to the arms of traditional glasses.
According to some embodiments of the present disclosure, the dimensional ranges of the eyewear may be, by way of example, as follows (the manner of determining these measurements according to some embodiments of the present disclosure is illustrated in FIG. 12):

    
    
        A measurement: (temple to the nose piece): 40-90 mm, or any values or ranges of values in between, e.g., 50-54 mm
        B measurement: (top of lens to bottom of lens): 15 mm-100 mm, or any values or ranges of values in between
        Nose piece measures, the DBL (distance-between-lenses): 1-25 mm width, or any values or ranges of values in between
    
    


Arm length (temple length): 100-180 mm, or any values or ranges of values in between.
FIGS. 1-9 illustrate multiple embodiments and aspects relating to vision enhancing eyewear. These figures are shown two-dimensionally from the aspect of an observer viewing the apparatus from above. In some embodiments, the apparatus is symmetrical or substantially symmetrical with respect to the wearer's left and right eyes. For example, the same or similar design (e.g., optical elements) may be provided for both eyes to enable bilateral viewing (e.g., viewing of the same image(s)). In other embodiments, only one eye of the apparatus may have enhanced vision capability (e.g., with the other eyepiece being a traditional eyepiece (e.g., lens) for normal vision), or the two eyepieces may have different enhanced vision capabilities.
Turning to FIG. 1, one embodiment of vision enhancing eyewear 100 includes sidearms 102, nose piece 104, and eyepieces 106, which may be integrated into a single housing or frame (e.g., formed from plastic, metal and/or composite material) that is supported by the bridge of a wearer's nose. In some embodiments, this frame, 101, may contain cavities and/or attachments for electronic components, camera(s) optical components, microprocessor(s), service channel(s), wiring, connectors, transmitter(s), receiver(s), battery and electric power sources and charging devices. In some embodiments, the two sidearms 102 may be configured to extend from the body/eyepieces of the frame to beyond the wearer's skin that overlies the upper pinna of the ear and the skin overlying the temporal bone of the skull. In some embodiments, one or both eyepieces 106 may provide a visual image display surface for a wearer.
Apparatus 100 may include one or more optical elements 108 (e.g., condensing optical lens(es)) and/or one or more imaging devices 110 (e.g., sensors or photocells, which may include a silicon chip). In some embodiments, multiple imagers 110 may be provided within apparatus 100, where said imagers 110 may be the same, substantially the same, or different. Alternatively or additionally, apparatus 100 may include one or more image generators (e.g., one or more processors) 112 coupled to imager(s) 110. For example, one or more optical elements 108 may focus incident light either as waves of all wavelengths or photons of varied energy onto an imager 110. Two illustrative cardinal rays (solid lines labeled with arrow showing direction of the ray) are shown from an object (e.g., at a location approaching infinity) brought to a focus on the imager 110. Image generator(s) 112 may automatically execute non-transitory computer program instructions to perform image process(es) that, for example, process signal(s) (e.g., electrical and/or optical signals) from the imager 110 in order to enhance the luminance, contrast and/or other aspects of the signal(s). Image generator(s) 112 may include any suitable hardware, software, or combination thereof for performing the functions disclosed herein.
In some embodiments, imager(s) 110 and/or image generator(s) 112 may include one or more charge-couple devices (CCDs) and/or complementary metal oxide semiconductor (CMOS) imagers. Without intending to be limited, an example of a suitable imager 110 according to some embodiments of the present disclosure includes the Omnivision OV5116N CMOS imager or its equivalent or comparable device(s). Optical elements 108 and 110 and image generator(s) 112 are shown in FIG. 1 as being generally located within or otherwise coupled to nose piece 104 of apparatus 100. However, it will be understood that the presently disclosed embodiments are not necessarily limited to that configuration. Optical elements 108 and 110, and/or image processor(s) 112, can be placed in other location(s) within or coupled to apparatus 100 without departing from the spirit and scope of the described embodiments. For example, in some embodiments, image processor(s) 112 may be located within or adjacent to a sidearm 102, or in a standalone housing that is coupled (e.g., optically coupled, in electrical communication with, and/or wirelessly coupled) to apparatus 100.
In some embodiments, apparatus 100 may include optical system 114 (e.g., projector system, screen, or display device). Optical system 114 may be located in or coupled to a sidearm 102 of the eyewear, although other locations are possible in other embodiments (e.g., within or coupled to nose piece 104). An output of image processor(s) 112 may be coupled to an input of optical system 114 via any suitable optical, electrical and/or electromagnetic/radio/wireless connection(s). For example, such coupling may be made through the eyepiece portion of the frame of apparatus 100. Without intending to be limited, suitable examples of an optical system 114 implemented as a projector system that may be utilized in various embodiments of the present disclosure include one or more light emitting diode (LED) projectors, such as those manufactured by Fraunhofer (www.fraunhofer.de/en/press/research-news/2012/may/mini-projector-for-smartphones.html) and Lemoptix (www.lemoptix.com/technology/products/mviewmicroprojector) or their equivalent or comparable devices. Without intending to be limited, suitable examples of an optical system 114 implemented as a screen that may be utilized in various embodiments of the present disclosure include one or more screens used in the Carl Zeiss Cinemizer and/or the Vuzix Wrap 920, liquid crystal display(s), and light emitting diode screen(s).
In some embodiments, apparatus 100 may include one or more optical elements for providing the light generated by optical system 114 to the wearer's eye 122. For example, as shown, apparatus 100 may include mirror(s) 116 coupled to nose piece 104, mirror(s) 118 coupled to eyepiece frame 106, and one or more lens(es) 120. In some embodiments, lens 120 is connected to the apparatus at one or more of nose piece 104, eyepiece frame 106 and/or sidearm 102 (e.g., each lens 120 being connected to sidearm 102 and eyepiece frame 106). Light generated by optical system 114 may be reflected by mirror 116 towards mirror 118, which in turn reflects the light through lens(es) 120 to the wearer's eye.
In some embodiments, the apparatus described in accordance with the present disclosure may have a wide dynamic range. Generally, dynamic range reflects the ratio between the maximum and minimum measurable light intensities (“white” and “black”) in an image. In some embodiments, the apparatus described herein detects incoming light, by way of example only, in the range of one to one thousand lux (a factor of approximately 1,000 fold, equivalent to approximately 30 db, equivalent to approximately 10 base-2 stops) or any value or range of values in between.
Referring again to FIG. 1, and for example, in some embodiments apparatus 100 may include one or more analog-to-digital converters (ADCs) for one or more pixel(s) of the imager or light sensor (e.g., one ADC per pixel). Such ADC circuitry may be included within, for example, image generator(s) 112. The ADC circuitry may convert incoming light signals to digital signals directly at the point of capture, thereby lowering degradation and cross-talk/ghosting (e.g., caused by overlapping of pixel images). This may allow for improved noise-reduction and dynamic range. Once in digital format, image generator(s) 112 may perform one or more computer processing methods for optimal or improved image reproduction.
In some embodiments, the apparatus described in accordance with some embodiments, may include a contrast enhancement capability. This capability may increase the extent to which adjacent areas of an optical image produced by the apparatus differ in luminance (“brightness”) and/or color. In various embodiments, contrast enhancement may be accomplished using physical element(s) (e.g., optical quality lenses such as used in single lens reflex cameras, which may be included within optical elements 108 and/or imager(s) 110), and/or digital elements(s) (e.g., electronic circuitry and/or software such as those used in camcorders, cell phone cameras or digital-only cameras, which may be included within image processor(s) 112). Alternatively or additionally, contrast enhancement may be accomplished by one or more of the following:

    
    
        1. Selecting (e.g., at the time of manufacture of the apparatus) or changing (e.g., during use by the wearer or automatically) a chemical composition of an optical element (e.g., image screen, mirror, amplifier, beam splitter, or lens) to absorb or better reflect desired wavelengths. This can include reflective (inorganic) metal chemistry, organic (e.g., dye) chemistry, or both.
        2. Selecting or changing incoming light filter chemical composition to absorb/transmit selective wavelengths. For example, yellow lenses (e.g., lens(es) 108) may be utilized in some embodiments to increase light/dark contrasts.
        3. Selecting or changing chemical composition of finishes on lenses, filters, and/or other optical elements to physically protect optical surfaces from scratching, thereby improving an ability to achieve contrast enhancement.
        4. Utilizing self-cleaning surface chemistries or chemical coatings (e.g., siliconization or silanization) that prevent water/salt damage (e.g., from perspiration, rain) or image occlusion that could negatively affect contrast.
        5. Selecting polymers and their purit(ies) for optical plastic components to prevent interference with contrast enhancements achieved in other system components.
    
    


In some embodiments, the apparatus described herein are intended to enhance detection of local luminance differences on the order of, by way of example only, up to 3 fold, up to 10 fold, up to 25 fold, or any value or range of values in between.
Without intending to be limited, suitable contrast enhancement functionality that may be utilized in various embodiments of the present disclosure is included in the contrast enhancement functionality of the Blackberry Bold cell phone camera, Sony camcorders utilizing TruBlack technology, the Samsung HMX-S10BP camcorder, the Panasonic HC-V100K recorder, the VEM110 Adimec Video contrast enhancement module, or their equivalent or comparable functionalities.
In some embodiments, the apparatus described in accordance with the present disclosure may include a digital zoom capability. For example, the digital zoom capability provided by the apparatus described herein according to some embodiments may include digital zoom up to 2 fold, up to 5 fold, up to 10 fold, up to 15 fold, up to 25 fold, or any value or range of values in between. For example, referring again to FIG. 1, in some embodiments, a digital zoom function may be enabled by computer software in, connected to, or otherwise controlling image generator(s) 112 of apparatus 100. The digital zoom function may decrease (narrow) the apparent angle of view of a digital photographic or video image and thus make the subject appear “closer”.
The digital zoom capability may include, for example, cropping an image and then stretching the cropped image to make it larger. In some embodiments, the resulting image can be the same size as the maximum resolution image but, because it has been stretched, no additional detail is visible. In some embodiments, this process can be accomplished electronically, with no adjustment of optics (e.g., lenses). Other image processing techniques may alternatively or additionally be used. For example, simply increasing the size of the pixels, with no downstream image modification or enhancement, might create a jagged or stair-stepped appearance. For this reason, different technique(s) (e.g., technique(s) also implemented by computer software utilized by image generator(s) 112) may be used to “fill in” the missing pixels. For example, apparatus 100 (FIG. 1) may include within image generator(s) 112 computer memory that stores computer-executable instructions (executable by one or more computer processors) for, for example, determining attributes of a pixel's nearest neighboring pixels and calculating an average, and/or taking other factor(s) into account to achieve a digital zoom. For example, without intending to be limited, suitable digital zoom functionality that may be utilized in various embodiments of the present disclosure is included in the digital zoom functionality of current cell phone cameras (e.g., Nokia Lumia cell phone cameras), Panasonic camcorders, Canon EOS digital cameras, Pelco Spectra IV surveillance cameras, Olympus Stereo Zoom microscopes, or their equivalent or comparable functionalities.
In some embodiments, the apparatus disclosed herein may include an optical zoom capability. For example, the optical zoom capability provided by the apparatus described herein according to some embodiments may include optical zoom up to 2 fold, up to 5 fold, up to 10 fold, up to 15 fold, up to 25 fold, or any other value or range of values in between. In some embodiments, the optical zoom capability utilizes the movement of physical lenses to change the focal length of a camera. Optical zoom makes the subject appear closer with maximum image quality. For example, referring again to FIG. 1, in some embodiments an optical zoom function may be provided by one or more lenses 108. For example, without intending to be limited, suitable optical zoom functionality that may be utilized in various embodiments of the present disclosure is included in the optical zoom functionality of current single lens reflex or digital/single lens reflex combination cameras, such as those manufactured by Nikon, Leica, Pentax, Olympus or Minolta; Nikon, Zeiss, Swarovski or Bushnell binoculars; Leupold, Minox, Weaver or Nikon target sighting scopes, or their equivalent or comparable functionalities.
In some embodiments, the apparatus disclosed herein may include a dynamic range scaling capability. For example, in some embodiments, the apparatus disclosed herein may re-scale the dynamic range of input signals (e.g., intensity and/or wavelength) to accommodate visual dynamic range responses, such as those amended by ophthalmic therapies including, by way of example only, gene therapeutics. This can be done by increasing or decreasing the brightness of a given scene (as can be done with current projectors, displays, and/or monitors), and/or attuning projected wavelengths to best match existing/remaining rhodopsins/opsins in the wearer's retina. By way of example, the latter can include converting a color scene to gray-scale, but may also incorporate other light wavelengths as the wearer's spectral response best dictates. By way of further example, a color scene may be converted to predominantly blue (450-495 nm), green (495-570 nm), yellow (570-590 nm), red (620-750 nm) or blended combinations thereof. In some embodiments, the dynamic range scaling capability may be provided as part of image generator(s) 112.
FIG. 2-7B are diagrams of vision enhancing eyewear in accordance with other embodiment of the present disclosure. These embodiments may include the same or similar sidearms 102, nose piece 104, eyepieces 106, optical element(s) 108, imager(s) 110, and/or image generator(s) 112 as described above in connection with FIG. 1. Accordingly, only the additional details in connection with the embodiments of FIGS. 2-7b are described below.
Turning to FIG. 2, apparatus 200 may include optical system 214, which may be similar to optical system 114 (FIG. 1) albeit coupled to an eyepiece 106 instead of a sidearm 102. Apparatus 200 may also include one or more optical element(s) (e.g., one or more lenses), which may be the same as or similar to optical element(s) 120 (FIG. 1). The apparatus of FIG. 2 may transmit an image to the wearer's eye from an optical system (e.g., projector system or screen) located in or coupled to one of the eyepieces of the apparatus. The apparatus may also include one or more optical elements (e.g., a lens or lens system for refraction) to allow the image to be rendered in such a fashion that the human eye, with or without additional optical correction, can focus the light.
FIG. 3 is a diagram of a vision enhancing eyewear apparatus in accordance with yet another embodiment of the present disclosure. As shown, the apparatus may transmit an image to the wearer's eye from an optical system (e.g., projector system or screen) located in or coupled to a side arm of the apparatus. Light generated by the optical system may be reflected by one or more optical elements (e.g., a mirror) in or coupled to an eyepiece. The apparatus may also include another one or more optical elements (e.g., lens or lens system for refraction) to allow the image to be rendered in such a fashion that the human eye, with or without additional optical correction, can focus the light. Accordingly, as shown, eyewear apparatus 300 may include optical system 322 (e.g., movie projector), which may be similar to optical system 114 (FIG. 1). Apparatus 300 may also include one or more mirrors 318, which may be the same as or similar to mirror(s) 118 (FIG. 1), and one or more optical element(s) (e.g., one or more lenses), which may be the same as or similar to optical element(s) 120 (FIG. 1). In FIG. 3, light from optical system 322 is reflected by mirror(s) 318 through optical element(s) 120 and into a wearer's eye. FIG. 10a and FIG. 11 are optical ray diagrams illustrating how the apparatus described in FIGS. 3, 4, and 6 can be configured to render an image in such a fashion that the human eye, with or without additional optical correction, can focus the light.
FIG. 4 shows an apparatus that is similar to FIG. 3, except the optical system 424 (same as or similar to optical system 322 in FIG. 3) is coupled to nose piece 104. As shown, the apparatus may transmit an image to the wearer's eye from an optical system (e.g., projector system or screen) located in or coupled to a nose piece of the apparatus. Light generated by the optical system may be reflected by an optical element (e.g., mirror) in or coupled to an eyepiece. The apparatus may also include one or more optical elements (e.g., lens or lens system for refraction) to allow the image to be rendered in such a fashion that the human eye, with or without additional optical correction, can focus the light.
FIG. 5 employs a video projector system 526 to generate the image transmitted to the eye whereas FIG. 1, in some embodiments, uses a screen. As shown, the apparatus may transmit an image to the wearer's eye from an optical system (e.g., projector system or screen) located in or coupled to a side arm of the apparatus. Light generated by the optical system may be reflected by an optical element (e.g., mirror) placed in a nose piece of the apparatus and in turn reflected by another optical element (e.g., mirror) placed in an eyepiece. The apparatus may also include one or more optical elements (e.g., lens or lens system for refraction) to allow the image to be rendered in such a fashion that the human eye, with or without additional optical correction, can focus the light. For example, in some embodiments, FIG. 5 employs a video projector system to generate the image transmitted to the eye, whereas FIG. 1 may use a screen in some embodiments.
FIG. 6 is a diagram showing another embodiment of vision enhancing eyewear according to the present disclosure, in which the housing of the apparatus includes a beam splitter, located in or coupled to the nose piece and frame of the eyewear, that is coupled to an optical system (e.g., two projectors) to provide an image to both of the wearer's eyes. Accordingly, the illustrated apparatus includes beam splitter 630, located in or coupled to the nose piece and frame of the eyewear. Beam splitter 630 is coupled to an optical system (e.g., projector system or screen), which may be the same as or similar to optical system 424 (FIG. 4), to provide an image (e.g., same or similar image) to both of the wearer's eyes.
FIG. 7 is a diagram of vision enhancing eyewear in accordance with still another embodiment of the present disclosure. As shown, the apparatus may transmit an image to the wearer's eye from an optical system (e.g., projector system or screen) located in or coupled to a side arm of the apparatus. Light generated by the optical system may transmitted by optical elements comprising one or more prism(s) and/or mirror(s) and/or lens(es) housed in the arm and/or frame of the apparatus to transmit the image generated by the optical. The apparatus may also include one or more optical elements (e.g., lens or lens system for refraction) to allow the image to be rendered in such a fashion that the human eye, with or without additional optical correction, can focus the light. FIG. 7 may differ from FIGS. 1,3, 4, 5 and 6 because the embodiment may employ prism(s) and/or mirror(s) and/or lens(es) to transmit the image generated by the optical system (e.g., projector system or screen) to the eye, whereas in some instances the other embodiments may not.
FIGS. 8A and 8B are diagrams of vision enhancing eyewear in accordance with yet other embodiments according to the present disclosure, in which incident or ambient light is captured by multiple imaging systems (e.g., multiple cameras). As shown, apparatus 800 may include two or more (typically within the range of two to five)—cameras 108 and 109 coupled to imager(s) and/or image generator(s) similar to or the same as those described in FIG. 1. For example, one or more cameras may be for low light image construction, and other cameras may be for other image construction (e.g., near-vision construction, where near vision refers to a commonly used phrase in ophthalmology describing vision for objects 1 meter or closer to the viewer). In some embodiments, the apparatus may include either a manual (e.g., switch) or automatic adjustment capability that causes the images from the lenses to be transmitted to both eyes. In some embodiments, consistent with human monovision, a distant image focused by one lens and near image focused by the other lens may be simultaneously transmitted to one or both eyes. In FIG. 7a, the lenses and imagers 110/111 are shown to be part of (in or coupled to) nose piece 104 of the eyewear. In FIG. 7b, the lenses and imagers 110/111 are shown to be placed in any other location in or coupled to the frame 106 of the apparatus (e.g., within the eyepiece portion of the frame).
FIGS. 9A and 9B, are diagrams of vision enhancing eyewear in accordance with yet other embodiment according to the present disclosure. In this embodiment, the wearer is able to view through the eyepieces in the same fashion as through the wearer's ametropic correction, by way of examples, but not limited to myopic, hypermetropic, balance and astigmatic correction, incorporating appropriate corrections for best vision sphere and back vertex distance. In this embodiment, the eyepiece of the apparatus comprises both a clear portion and a viewing screen 914, for projected images. Element 914 viewing screen may comprise any available display system, for example the OLIGHTEK OLED microdisplay (www.OLIGHTEK.com), may transmit an image to the wearer's eye from any of the optical systems and elements previously described in FIGS. 1-7 and the image will be presented to the wearer in some portion of element 914, which may be situated at, for example but not limited to, the infero-nasal part of the eyepiece, an area of the eyepiece often utilized for the bifocal segment of an eyepiece lens. This embodiment may allow the wearer to choose whether to view an image/scene through the eyepiece lens 906, which may incorporate correction for the patient's ametropia or the image presented through the optical apparatus element 914.
