Description

TITLE: MULTICOMPONENT OPTICAL DEVICE FOR VISUAL AND AUDIBLE TRANSLATION AND RECOGNITION

BACKGROUND

Field

[0001 ] The present disclosure relates generally to multicomponent optical devices having a space within the device.

Discussion of the Related Art

[0002] The development of various miniaturized optical components and the ability to manufacture increasingly sophisticated optical features has driven a growing interest in adapting an expanding array of optical features and other types of technological products to lenses that can be worn on the surface of an eye. Adaptation of various optical features and other technologies to a wearable lens can produce optical devices having thicker lenses than can be accommodated while providing adequate oxygen supply to corneal tissue based on the gas exchange capacity of conventional gas-permeable optical materials and lens designs. Likewise, a variety of optical components may not comprise or be compatible with optical materials having the necessary properties of gas permeability to ensure adequate oxygen transmission to the cornea when placed on an eye.

[0003] There is thus a need in the art for optical devices that can modularly incorporate various optical components or features of interest while adequately providing for oxygenation of the corneal cells.

SUMMARY

[0004] In general, the present disclosure provides multicomponent optical devices having a space and related methods. For example, in various embodiments, a multicomponent optical device is provided that includes a first posterior component, a posterior support component, and an anterior component. The optical device can also comprise an anterior skirt. The first posterior component and the anterior skirt can comprise a gas-permeable optical material. The first posterior component can comprise an anterior surface and the anterior component can comprise a posterior surface, with the anterior surface and the posterior surface together defining a space within the optical device between the anterior component and the first posterior component. Multicomponent optical devices may be manufactured using, among other processes, 3D printing and other additive processes.

[0005] The configuration of the space, the gas-permeable optical materials, and other features of the multicomponent optical device can facilitate gas exchange through the device that is sufficient, for example, to permit oxygenation of the corneal tissue of an eye by a device comprising a finished lens. In various embodiments, an optical device an also include a peripheral space, and the peripheral space can be in fluid communication with the primary space via portals through device components to provide for gas exchange between the peripheral space and the primary space. The peripheral space can facilitate gas exchange with the atmosphere through the gas permeable material of the anterior skirt. Similarly, the primary space can facilitate gas exchange with, for example, corneal tissue of an eye to which a finished lens in accordance with various embodiments is applied through the gas permeable material of the first posterior component.

[0006] The present disclosure may provide multicomponent optical devices comprising contact lenses and/or spectacles, alone or in combination, that provide for the ability to translate languages by visual and/or audio means. Multicomponent optical devices as contemplated herein may also be able to recognize locations, objects, shapes and the like and provide an audio or visual description of the object to a user of the multicomponent optical device.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS

[0019] Persons skilled in the art will readily appreciate that various aspects of the present disclosure can be realized by any number of methods and systems configured to perform the intended functions. Stated differently, other methods and systems can be incorporated herein to perform the intended functions. It should also be noted that the accompanying drawing figures referred to herein are not all drawn to scale, but may be exaggerated to illustrate various aspects of the present disclosure, and in that regard, the drawing figures should not be construed as limiting. Finally, although the present disclosure can be described in connection with various principles and beliefs, the present disclosure should not be bound by theory.

[0020] As used herein, "anterior surface" refers to a lens surface closer to an eyelid, and "posterior surface" refers to a lens surface closer to a cornea of the eye.

[0021 ] As used herein, "optical device" can be used to refer to a device having optical features or qualities, including, for example, optical lens blanks, finished optical lenses or other devices or manufacturing process intermediates intended to be used for optical functions such as vision correction, aesthetics, or other optical functions.

[0022] As used herein, "optical feature" refers to a sagittal variation from substantially hemispherical (for example defined by a sigmoid, a third order polynomial, a conic constant, or an angle, which may be rotationally symmetric or asymmetric) in relation to very high powers and cylinders, bifocal designs and wavefront aberration nullification, polarization filters, refractive lenslets, diffractive lenslets, selective chromatic filters, bandpass filters, circular polarizing filters, linear polarizer filters, gray attenuator filters, birefringent filters, zone plates, mirrors, electronic circuits, electronic devices, microdisplays, telecommunication devices, sensors, antennas, nanowires, energy generation or storage devices, pharmaceutical delivery devices, cameras, etc.

[0023] As used herein, "fluid communication" refers the ability of a fluid (i.e., a liquid, gas, or semi-solid) to move or flow from one location to another location. In the context of the present disclosure, the term "fluid communication" may be used to describe a property of spaces or conduits suitable to permit a flow of a gas or liquid between two locations, such as by bulk flow or diffusion.

[0024] Referring to Figures 1 A-1 C, views of a finished multicomponent lens 100 in accordance with various embodiments of the present disclosure are illustrated. Lens 100 can comprise hard, semi-hard or soft optical materials, as described in more detail below, and can be configured for vision correction, orthokeratology, aesthetics or display technology, to name just a few functions. In various embodiments, a finished lens can be a scleral, corneo-scleral, or corneal lens. Lens 100 can have an outer diameter of from about 5 mm to about 20 mm, with smaller or larger diameters being possible in special cases. By way of non-limiting example, a scleral contact lens can have an outer diameter of up to about 28 mm or more. Furthermore, a finished lens can be radially symmetrical, bilaterally symmetrical, or non-symmetrical, and can include bifocal, toric, or quadrant specific optical features or geometries.

[0025] In accordance with various embodiments and as described in greater detail below, lens 100 may be manufactured from a multicomponent optical device, with the finished lens also comprising a multicomponent lens that can include a first posterior component 102, a posterior support component 104, and an anterior component 106. The lens can also include a primary space 1 10 defined by a posterior surface of the anterior component 106 and an anterior surface of the first posterior component 102. A lens can also comprise an anterior skirt 108, which may or may not comprise a portion of first posterior component 102, along with a peripheral space 1 12 located between the peripheral skirt and the posterior support component. First posterior component 102 and anterior skirt 108 can comprise gas- permeable optical materials that, in combination with primary space 1 10, peripheral space 1 12, and portals 1 14 connecting the spaces, serve to facilitate gas exchange between an anterior peripheral surface of the lens and a posterior central surface of the lens that would be located adjacent to the corneal tissue if applied to an eye. In this general manner and as described in greater detail below, a lens manufactured from an optical device in accordance with various embodiments can modularly incorporate any of a variety of optical features or devices in anterior component 106 while providing sufficient oxygenation to the corneal tissue of an eye to which the lens is applied.

[0026] With reference now to Figure 2, an optical device in accordance with various embodiments is illustrated. An optical device can comprise a multicomponent optical device blank, such as multicomponent optical device blank 200 illustrated in Figure 2, or an optical device can comprise a finished lens such as lens 100, illustrated in Figure 1 and described above. Broken lines in the cross section of blank 200 shown in Figure 2 depict the locations of finished lens anterior and posterior surfaces corresponding to the finished surfaces of lens 100, as shown in Figure 1 .

[0027] In various embodiments, multicomponent optical device blank 200 can comprise a generally cylindrical blank that includes a first posterior component 102, a posterior support component 104, and an anterior component 106. Blank 200 can further comprise an anterior skirt 108. In accordance with various embodiments, first posterior component 102 and anterior skirt 108 can be comprised of a gas-permeable optical material and can further comprise a single piece of material (i.e., first posterior component 102 and anterior skirt 108 can have a unitary construction, with anterior skirt 108 comprising a portion of first posterior component 102). In other embodiments and as described in greater detail below with reference to Figures 6, 7A, and 7B, an anterior skirt such as anterior skirt 608 can comprise a component that is separate from a first posterior component such as first posterior component 602.

[0028] First posterior components 102/602 and anterior skirts 108/608 can be comprised of the same material, or, if the first posterior component and the anterior skirt are separate components, as illustrated for blank 600 shown in Figure 6, can be comprised of different materials. First posterior components 102/602 and/or anterior skirts 108/608 can be comprised of one or more of fluorosilicon acrylate, silicon acrylate, polymethylmethacrylate, a silicon hydrogel, a biocompatible material, a transparent material, or another suitable material. In general, any gas permeable, biocompatible material is suitable for use in first posterior components 102/602 and/or anterior skirts 108/608.

[0029] With reference now to Figures 2, 3A, and 3B, first posterior component 102 can comprise an anterior component receiving portion and a shaft portion 220. The anterior component receiving portion can comprise a circumferential wall and a bottom wall defining a cavity that is open on an anterior end for receiving an anterior component such as anterior component 206. Shaft portion 220 can comprise a cylindrical axial projection with a configuration that is complementary to and configured to slide within a shaft receiving portion 222 of posterior support component 104, described in greater detail below. The bottom wall of first posterior component 102 can comprise an anterior surface 203. In various embodiments, anterior surface 203 may comprise a convexly curved, optically finished surface, and may further be of a diameter that approximates or is otherwise proportionally related to a diameter of a cornea or other anatomical feature of an eye. As described in greater detail below, anterior surface 203 can define a posterior wall of primary space 1 10 of an assembled multicomponent optical device blank 200 or lens made therefrom, such as lens 100 (Figure 1 ). In various embodiments, the circumferential wall of first posterior component 102 can comprise anterior skirt 108, additional features of which are also described in greater detail below.

[0030] First posterior component 102 may also comprise various reference features, reference surfaces and/or functional surfaces. For example, and with continued reference to first posterior component 102 comprising unitary anterior skirt 108, first posterior component 102 can comprise one or more reference features such as ridges 218 and/or grooves 219. Ridges and/or grooves may have any of a variety of profiles and be complementary to corresponding reference features such as grooves and/or ridges located on the surfaces of other optical device components, such as posterior support component 104 or anterior component 106. Reference features may serve to enhance the location, alignment, and integrity of fit between components of an optical device.

[0031 ] Similarly, first posterior component 102 may comprise one or more reference surfaces. A reference surface may be oriented in any direction and may provide a point or plane of reference for alignment of the component with a second component, such as by physical contact between one reference surface and a second reference surface. For example, the peripheral surface of shaft portion 220 may comprise a reference surface suitable for determining alignment of the first posterior component 102 during a mating process with posterior support component 104 in which first posterior component 102 is slideably received by posterior support component 104. First posterior component 102 may also comprise a reference surface such as a transverse surface configured to align with a corresponding (i.e., complementary) transverse reference surface of posterior support component 104 or anterior component 106. Such a transverse reference surface may face anteriorly or posteriorly and may provide a positive stop during assembly of the first posterior component 102 with another device component in an optical device manufacturing method that may rely on an interference fit between pre-formed device components. For example, a method of assembling an optical device can comprise a step of inserting first posterior component 102 into posterior support component 104, which step can proceed until one or more sets of corresponding transverse reference surfaces align with one another.

[0032] In addition, first posterior component 102 can also comprise functional surfaces. In this regard, as used herein, a "functional surface" can be any surface that contributes to a functional and/or structural feature of an assembled optical device. A functional surface can include anterior surface 203 of first posterior component 102, as mentioned briefly above and described in more detail herein. Referring briefly to Figures 6, 7A, and 7B, first posterior component 602 can also comprise a functional surface such as anterior surface 603. First posterior component 102 can also comprise a peripheral posterior surface 21 1 configured to provide a peripheral space 1 12 between the surface and a peripheral anterior surface 213 of posterior support component 104 in an assembled optical device. Similarly, and with reference again to Figure 6, anterior skirt 608 can comprise peripheral posterior surface 61 1 and be configured to provide a peripheral space 612 between the surface and a peripheral anterior surface 613 of posterior support component 604. Peripheral posterior surface 61 1 and peripheral space 612 may furthermore have any of the features or characteristics described in more detail below with reference to peripheral posterior surface 21 1 and peripheral space 1 12.

[0033] Referring again to Figures 2, 3A, and 3B, in various embodiments, peripheral posterior surface 21 1 may comprise a surface described by one or more radial lines having an angular deviation from the axis of optical device blank 200. For example, peripheral posterior surface 21 1 can be described by an interior surface of a segment of the altitude of a hollow cone, along with a shorter and steeper angular radial segment configured to connect the periphery of the conical segment surface described above with a surface of the posterior support component 104 (i.e., peripheral anterior surface 213) in an assembled optical device. In various embodiments, the peripheral posterior surface 21 1 may be configured to provide a continuous circumferential peripheral space 1 12 in an assembled optical device. In other embodiments, peripheral posterior surface 21 1 may be configured to provide a peripheral space having a different and/or a varying size and/or shape, or may be configured to provide a plurality of peripheral spaces in an assembled optical device.

[0034] In accordance with various embodiments, the peripheral space 1 12 defined by the assembled optical device can facilitate gas exchange between a peripheral surface of optical device blank 200, or an anterior peripheral surface of a finished lens manufactured from the blank (such as lens 100 illustrated in Figure 1 ), and the primary space 1 10, as described below. In various embodiments, gas exchange can occur between peripheral space 1 12 and a peripheral surface of the optical device or a finished lens via the gas permeable material comprising first posterior component 102 and/or anterior skirt 108. In other embodiments, gas exchange may occur via fenestrations or other openings between peripheral space 1 12 and a peripheral surface of the optical device or a finished lens. Gas exchanged between the outside of the device or lens and peripheral space 1 12 can further be exchanged with primary space 1 10 as described in greater detail below.

[0035] First posterior component 102 can comprise one or more openings such as portal 1 14 communicating between peripheral space 1 12 and primary space 1 10. In accordance with various embodiments, a portal 1 14 can be any type of hole or passageway through the material of the first posterior component 102, with the portal 1 14 configured to provide fluid communication between the primary space 1 10 and the peripheral space 1 12 defined by the assembled optical device. In various embodiments, first posterior component 102 comprises one or more portals 1 14 configured to connect a peripheral portion, such as a peripheral wall, of the primary space 1 10 to peripheral space 1 12. The number and configuration (i.e., size and shape) of the portals 1 14 in an optical device such as finished lens 100 (Figure 1 ) may be suitable to permit sufficient gas exchange to enable adequate oxygenation of the corneal tissue of an eye to which the finished lens is applied. Expressed differently, the number and configuration of the portals 1 14 do not restrict the capacity of an optical device blank 200 or a lens made therefrom to provide adequate gas exchange between an anterior peripheral surface of the device or lens and a posterior surface (i.e., the surface adjacent the cornea of an eye in a finished lens applied to an eye).

[0036] Referring to multicomponent optical device blank 600 illustrated in

Figure 6, posterior support component 604 may comprise portals 614 that have a configuration and perform a function similar to that described above for portals 1 14, with portals 614 configured to provide fluid communication between peripheral space 612 and primary space 610. In various embodiments, a first posterior component such as component 602 may also have portals 621 that align with portals 614 and thereby further provide fluid communication between peripheral space 614 and primary space 610. Portals 621 may be drilled or otherwise created in first posterior component 602 using any suitable method following mating or assembly of first posterior component 602 with posterior support component 604. In various embodiments, drilling or creating portals 621 after mating or assembly of the components assures alignment of portals 621 with portals 614 and fluid communication between peripheral space 614 and primary space 610. Possible locations of portals 621 in first posterior component 602 of assembled multicomponent optical device blank 600 are outlined with broken lines in Figures 6A and 6B.

[0037] In various embodiments, portals 621 may be included in first posterior component 602 prior to mating with another component of a multicomponent optical device. For example, Figure 7 A illustrates a first posterior component 602 including portals 621 . In various embodiments, portals 621 that may be included in first posterior component 602 prior to mating or assembly may have configurations comprising elliptical, rectangular, or other cross-sectional profiles that may aid in alignment of portals 621 with portals 614 following mating of first posterior component 602 and posterior support component 604.

[0038] In various embodiments, a portal 614 in fluid communication with peripheral space 612 may not be in fluid communication with primary space 610. Instead, a portion of first posterior component 602 such as a ridge or flange may occlude fluid communication between portal 614 and primary space 610; however, gas exchange between the primary space 610 and portals 614 (the portals 614 being in fluid communication with peripheral space 612) can still take place due to the gas- permeable material comprising first posterior component 602.

[0039] In general, optical device blank 600 comprises components and features that are similar to those of optical device blank 200, as described herein, with the exceptions that portals 614 can be included in posterior support component 604, as described above, and that the anterior skirt 608 comprises a separate component from first posterior component 602. However, the various other features described herein with respect to optical device blank 200 may generally be found in optical device blank 600, and equivalent features between the two optical devices are referred to in the description and in the figures using equivalent numbering.

[0040] With reference now to Figures 4A and 4B, along with continued reference to Figure 2, an optical device such as blank 200 can also comprise a posterior support component 104. In various embodiments, posterior support component 104 can comprise a rigid optical material that is biocompatible. Posterior support component 104 may or may not comprise a gas permeable material. In accordance with various embodiments, posterior support component 104 comprises a material of suitable hardness and/or rigidity to provide structural support to an optical device such as optical device blank 200 and/or finished lens 100 (Figure 1 ). For example, posterior support component 104 may provide structural support for first posterior component 102, anterior skirt 108, and anterior component 106 for at least a portion of a method of manufacturing an optical device and/or a finished lens. The posterior support component 104 may also provide structural support for an optical device comprising a finished lens, for example, a lens such as finished lens 100 (Figure 1 ), by providing stabile, flexure-resistant support for a finished multicomponent optical lens with suitable apical clearance as applied to an anterior scleral surface.

[0041 ] In various embodiments, posterior support component 104 can comprise a cylindrical shape with a circumferential wall and an open anterior end defining a cavity within the component. The cavity of a component can generally comprise a receiving portion configured to receive a separate optical device component, such as first posterior component 102, that may be inserted into the cavity or receiving portion. The posterior end can include a bottom wall further comprising a shaft receiving portion 222 with an opening having a diameter that is reduced with respect to the open anterior end of the posterior support component 104. As described above, the opening of the shaft receiving portion 222 and the cavity of posterior support component can be configured to slideably receive first posterior component 102.

[0042] Posterior support component 104 can further comprise an axial wall 224 defining a protrusion from a posterior surface of the bottom wall along with the posterior or bottom opening of the shaft receiving portion 222. In various embodiments, the peripheral surface of axial wall 224 and/or the peripheral surface of posterior support component 104 may be suitable for attachment in the collet of a lathe, for example, to facilitate machining of an anterior surface of optical device blank 200.

[0043] Posterior support component 104 can also comprise reference features, reference surfaces, and functional surfaces similar and/or complimentary to those previously described with respect to first posterior component 102. For example, posterior support component 104 can comprise a peripheral anterior surface 213, that, together with peripheral posterior surface 21 1 of first posterior component 102 in assembled optical device blank 200, defines peripheral space 1 12. Likewise, posterior support component 104 can comprise one or more reference surfaces oriented transversely to the axis of optical device blank 200 that may serve as a positive stop for insertion of first posterior component 102 during a process of assembling optical device blank 200.

[0044] Referring now to Figures 5A and 5B, and with continued reference to Figure 2, an optical device such as blank 200 can also comprise an anterior component 106. In various embodiments, anterior component 106 comprises a cylindrical shape and may have an insertion portion configured for insertion into an anterior component receiving portion of first posterior component 102. Anterior component 106 can also include a peripheral flange comprising a reference surface configured to align with a complimentary reference surface of another optical device component such as first posterior component 102. Likewise, anterior component 106 can further include a reference feature such as those described elsewhere herein. [0045] In accordance with various embodiments, anterior component 106 also comprises posterior surface 207, which can define the anterior boundary of primary space 1 10. In various embodiments, posterior surface 207 may comprise a concavely curved, optically finished surface, and may further be of a diameter that approximates or is otherwise proportionally related to (i.e., is the same as, is larger than, is 5% smaller than, etc.) a diameter of a cornea or other anatomical feature of an eye.

[0046] In accordance with various embodiments, anterior component 106 can comprise any optical device or optical feature, as defined herein. An optical device in accordance with the present disclosure, such as blank 200, or a finished lens made therefrom, such as finished lens 100 (Figure 1 ), may provide certain previously unrealized benefits conferred by the structure of the device as described herein that afford substantial latitude in the configuration of anterior component 106 (e.g., thickness) as well as the materials and/or optical features (e.g., gas impermeable materials and/or features that might impede gas exchange of an optical material) used in anterior optical component 106.

[0047] In accordance with various embodiments, multicomponent optical devices such as contact lenses and/or spectacles, alone or in combination, provide object recognition capabilities with features such as the ability to translate languages by visual and/or audio descriptors to the user of such devices. Multicomponent optical devices as contemplated herein may also (or alternatively) be able to recognize locations, objects, people (e.g., facial recognition), shapes and the like and provide visual and audible translations or descriptors of the object to a user of the multicomponent optical device.

[0048] For example, in accordance with various embodiments and with reference to Figure 9, an object recognition system as contemplated herein comprises at least one contact lens 900 such as disclosed herein and a pair of spectacles 920 (e.g., glasses which may prescription, protective, or the like). The contact lens 900 and spectacles 920 may wirelessly communicate, for example, via Bluetooth, RF or other wireless communication mechanisms, now known or as yet unknown, to facilitate the ability of a user to view information presented (e.g., via LED, projection, etc.) on the lenses of the spectacles 920 notwithstanding the close proximity of the user's eye, contact lens 900, and spectacles 920, which would otherwise be difficult or impossible for a user to discern.

[0049] The system also includes a processor 930 and object recognition software 940. In various embodiments, an optical feature 950, for example, a miniaturized camera, is provided and configured to receive an image of an object 960 and communicate a digital rendition of the image to the processor 930 and software 940 so that the processor 930 and the object recognition software 940 can generate a descriptor 970 of the object 960 and present the descriptor 970 to a user of the object recognition system. In accordance with other embodiments, the optical feature may comprise other components such as those listed above, among others. Similarly, in various embodiments, the miniaturized camera may be configured to receive an image of a person's face, and communicate a digital rendition of the image to the processor 930 and software 940 so that the processor 930 and the object recognition software 940 can generate a descriptor 970 of the object 960 and present the descriptor 970 to a user of the object recognition system, based on a previous association of a name with the image, which may be beneficial in helping a user remember a person's name.

[0050] In accordance with various embodiments, the optical feature may have its own "onboard" micro-power source or may be powered as necessary via external power sources, such as by induction (magnetic and other energy fields) or other wireless energy sources. In the case of onboard micro-power sources, these may be charged wirelessly by similar induction type sources while the lens are being worn, or alternatively may be charged when removed by similar means or via a wired connection to a micro-port on the contact lens 900 or the optical feature 950 itself.

[0051 ] In accordance with various embodiments, the descriptor 970 can be a visual descriptor 971 presented on the spectacles 920 for viewing by the user, while in other embodiments, the descriptor 970 can be an audio descriptor played for the user, for example, via a speaker 972 located on the spectacles. In other embodiments, the audio descriptor may be played through speakers located elsewhere, such as through an ear piece or headphones, wirelessly (e.g., Bluetooth, etc.) or wired, or through other audio components (radios, music players, computer speakers, mobile phone, tablet or other PDA speakers, etc.). In some embodiments, both a visual descriptor 971 and an audio descriptor 972 may be presented.

[0052] In accordance with various aspects of the present disclosure and with reference now to Figure 10, the object 960 may be one or more words 961 , and the object recognition software 940 may be language translation software (conventional "off the shelf" software or software configured for a specific application) capable of translating the words 961 from one language to another. After translation, the descriptor 970 of the words 961 may be a visual translation of the words shown in another language. For example, Figure 10 illustrates the word "ALTO" displayed as "STOP" when translated from Spanish to English. Alternatively, the foreign words 961 may be represented as an image or graphic. For example, "aeropuerto," Spanish for "airport," may be displayed as an airplane symbol. Depending on the configuration of the object recognition system, any languages may be translated (e.g., English, French, German, Spanish, Japanese, etc.).

[0053] Alternatively (or in addition), the descriptor 970 of the object 960 may be an audio descriptor of the words 961 translated. With continued reference to Figure 10, "ALTO" is translated and played for the user audibly as the English word "STOP" through speaker 972. Again, depending on the configuration of the object recognition system, any languages may be used.

[0054] In various embodiments, the object recognition software 940 may also recognize common shapes or colors, such as the octagonal shape and red color of a stop sign, and visually and/or audibly describe the same to the user. For example, in accordance with various aspects of the present disclosure, the object 960 may be a stop sign such as illustrated in Figure 10 or may be a symbol, sign or other item (a "thing") such as symbol for a bathroom, or a fork, a chair, a mailbox, etc. and the object recognition software comprises spatial recognition software 931 (again, conventional "off the shelf" software or software configured for a specific application) capable of identifying the object 960 and generating a visual and/or audio representation describing the symbol or item. For example, in the case of a blind user, when presented with a chair, the object recognition system will audibly inform the blind person that the object 960 is a chair.

[0055] In another example, with reference now to Figure 1 1 , a typical bathroom sign 963 is illustrated. The spatial recognition software 931 identifies the bathroom sign 963 and generates a visual descriptor 973 displaying the word "BATHROOM" in any number of languages, and/or audibly plays the word "BATHROOM" for the user, also in any number of languages.

[0056] Still further, as mentioned above, the object recognition software 931 may also be able to recognize faces and display our audibly play a name associated with the face to the user. For example, a miniaturized camera may be configured to receive an image of a person's face, and communicate a digital rendition of the image to the processor 930 and software 940, which at the user's discretion may allow the user to store the image and enter a name (and other information such as employer, relationship with others, etc.) associated with that person, either at that time or at a later date. Upon encountering the same person at a later time, the user may prompt the system to use the processor 930 and the object recognition software 940 to generate the name associated or other information associated with the person to assist in helping the user remember the name and other information. The information may be displayed visually or audibly played to the user. In the case of audible presentation, a headset or Bluetooth like device inserted in the user's ear, may be advantageous because it may allow a name to be discreetly presented to the user, without others hearing.

[0057] In accordance with various aspects of the present disclosure and with reference to Figures 1 C and 9, the optical feature 950 may be a camera embedded in the contact lens 900, though alternatively, the optical feature 950 may be mounted on the spectacles 920, or elsewhere. Similarly, in accordance with various aspects, the processor 930 may be integrated with the contact lens 900, the spectacles 920, or elsewhere. For example, the processor 930 and the object recognition software 940 may be carried in an external device such as a PDA, smartphone, tablet, laptop computer, or the like.

[0058] Further, in various embodiments, contact lenses 900 as contemplated with the object recognition system disclosed herein may be configured as disclosed herein, for example, having a first posterior component comprising a gas-permeable optical material and an anterior surface, a posterior support component, wherein the posterior support component provides structural support for the anterior component which may contain the optical feature 950, an anterior skirt comprising a gas- permeable optical material, and a primary space between the posterior surface of the anterior component and the anterior surface of the first posterior component, with the primary space being configured to permit diffusion of a gas from a perimeter of the primary space through the primary space and across the anterior surface of the first posterior component. Alternatively, the optical feature 950 may be contained with the primary space, or elsewhere in the contact lens.

[0059] Similarly, methods using the object recognition system comprise providing at least one contact lens 900 and a pair of spectacles 920, receiving an image of an object 960 to be recognized through the contact lens 900 and spectacles 920, then communicating a digital rendition of the image to a processor 930, the processor 930 generating a descriptor 970 comprised of at least one of an audio descriptor and a visual descriptor 971 of the object; and then presenting the descriptor 970 to a user.

[0060] In accordance with various embodiments and as mentioned above, a multicomponent optical device can comprise a primary space 1 10 configured to provide gas exchange for the corneal tissue of an eye. In various embodiments, the primary space has a diameter sufficient to provide gas exchange from the primary space through the posterior wall (i.e., a portion of gas permeable posterior component 102) of the space to the corneal tissue that would underlie an eye to which the optical device was applied. Likewise, a primary space can have a height (i.e., a distance between the anterior wall and the posterior wall of the space) that is sufficient to permit molecular diffusion of a gas such as oxygen and/or bulk flow of air (or any other fluid) from a peripheral portion of the primary space 1 10 to a remote portion of the primary space, such as the central portion that is most distant from the periphery of the primary space. Expressed differently, the configuration of the primary space, including, for example, the distance and uniformity of the dimension between the anterior and the posterior walls; the diameter of the primary space; the three-dimensional shape of the primary space; the configuration of a peripheral space and the number, size, and configuration of portals communicating between the peripheral space and the primary space; the requirement for structural support such as support rings within the primary space; the overall configuration of the lens including the size and shape of the lens; the composition of the oxygen permeable materials used in the gas exchange zones; and the thickness and surface area of the device in the gas exchange zones; may influence, and can be designed or engineered to accomplish, the optical performance objectives of the multicomponent optical device while providing for sufficient gas exchange of the corneal tissue to ensure corneal tissue health during wear.

[0061 ] In various embodiments, a primary space 1 10 can also comprise a peripheral channel 230 located at the perimeter or peripheral circumference of the primary space. A peripheral channel 230 can be defined by an anterior component such as anterior component 106 and a first posterior component such as first posterior component 102 and can be continuous with primary space 1 10. The peripheral channel 230 can be formed or defined by a feature such as a jog or other change in the profile of the anterior component 106, the first posterior component 102, or both. In various embodiments, the peripheral channel of primary space 1 10 can have a height that is greater than the height of the primary space. The peripheral channel portion of primary space 1 10 may serve as the portion of the primary space to which portals 1 14 connect (i.e., portals 1 14 open in or on the peripheral channel of primary space 1 10).

[0062] Primary space 1 10 can be filled with any medium, or number of mediums, of matter, for example a gas (e.g., air or oxygen), a liquid (e.g., water or saline), and a solid (e.g., a gel or a rigid solid).

[0063] In accordance with various embodiments, the configuration of the primary space of an optical device is not deformable, such as to provide adaptability of the optical device to external pressure changes. In various embodiments, a supplementary support component may be included in the primary space of an optical device. For example and with reference to Figure 2 and Figure 8, an optical device may include a porous spacer ring 216 in primary space 1 10. Porous spacer ring 216 may comprise a ring having a height corresponding to the distance between anterior surface 203 and posterior surface 207 defining primary space 1 10, as well as a diameter smaller than the diameter of primary space 1 10. In various embodiments, a porous spacer ring 216 can be an independent component, as illustrated in Figure 8, or a porous spacer ring can comprise or be integral to another component of a device such as anterior component 106 or first posterior component 102. Porous spacer ring 216 can comprise any suitable material, such as an optical material or other structural material. Porous spacer ring 216 can be configured be configured to fit within a primary space 1 10 and to have a diameter and/or thickness suitable to minimize interference with the optical performance of the device or appearance as a visible artifact to a wearer. Porous spacer ring 216 may also comprise portals or holes 840 in the walls of the ring that enable substantially unobstructed gas exchange within the primary space but do not compromise the ability of the ring to provide supplemental structural support for a uniform height of primary space 1 10 in an optical device.

[0064] In accordance with various embodiments and with reference to Figure 2, a multicomponent optical device, such as optical device blank 200, can be prepared by a process comprising mating separate device components and bonding the mated components to form a multicomponent optical device. For example, a multicomponent optical device can be prepared by a process comprising mating a gas-permeable first device component, such as first posterior component 102, to a second device component, such as posterior support component 104. In various embodiments, mating can comprise inserting a preformed device component into a receiving portion of a second device component. In other embodiments, mating can comprise injection molding, casting, or otherwise forming or depositing material of one device component into another device component.

[0065] A multicomponent optical device can further be prepared by bonding the first device component to the second device component. In accordance with various embodiments, bonding can comprise an interference fit between one or more surfaces and/or surface features of each component. Bonding can also comprise applying an adhesive, welding, or otherwise joining the first device component to the second device component. In various embodiments comprising mating by processes such as molding or casting, mating and bonding may not comprise distinguishable process steps. For example, mating and bonding may essentially occur together upon curing of the molded material. Likewise, where bonding comprises an interference fit, bonding may occur contemporaneously with mating or insertion of one device component into the second device component.

[0066] In various embodiments, a multicomponent optical device can be prepared by a process further comprising mating a third device component, such as anterior component 106, to the first device component. In accordance with various embodiments, following mating of the third device component to the first device component, a space such as primary space 1 10 remains between an anterior surface of the first device component and a posterior surface of the third device component, as described in detail elsewhere herein. In various embodiments, a multicomponent optical device may be prepared by placing a porous spacer ring, such as porous spacer ring 216, between the anterior surface of the first device component and the posterior surface of the third device component. A device can be prepared by further bonding the third device component to the first device component. Mating and bonding of the first and third device components can be performed as described above with respect to the first and second device components.

[0067] In various embodiments, a multicomponent optical device can be prepared by a process further comprising forming a peripheral space, such as peripheral space 1 12, between the second device component and an anterior skirt portion of the first device component. In various embodiments, forming a peripheral space may occur as a result of the completion of a mating and/or bonding step, for example, by aligning reference surfaces and/or functional surfaces of two or more separate components.

[0068] In accordance with various embodiments and with reference to Figure 6, a multicomponent optical device such as optical device blank 600 can be prepared by a process such as that described above with respect to blank 200, the process further comprising mating a gas-permeable anterior skirt component to at least one of the second device component and the third device component, wherein the anterior skirt component is mated separately from the first device component. In such embodiments, the anterior skirt component may comprise a separate component from the first device component. For example, first device component, second device component, third device component, and anterior skirt component may correspond to first posterior component 602, posterior support component 604, anterior component 606, and anterior skirt 608. The anterior skirt component may be bonded to at least one of the second device component and the third device component, and a peripheral space may be formed between the anterior skirt component and the second device component.

[0069] In accordance with various embodiments, the components of an optical device, such as blanks 200 and 600, can be mated in any logical order. For example, and with reference to Figure 6, first posterior component 602 may be mated to the other components in the last mating step, or first posterior component 602 may be mated to posterior support component 604 and anterior component 606 can be mated to anterior skirt 608, followed by mating of the two sets of components.

[0070] In accordance with various embodiments, a multicomponent optical device can be prepared by a process further comprising machining a finished lens from a multicomponent optical device blank such as multicomponent optical device blanks 100 and 600. In various embodiments, machining can comprise a process such as milling, lathing, or the like, to produce a finished lens such as a scleral lens that may be applied to an eye. [0071 ] In accordance with various embodiments, a method of manufacturing a multicomponent optical device is provided. A method can comprise inserting an anterior component comprising an insertion portion having a posterior surface into in a support structure comprising a receiving portion. A method can further comprise aligning a reference surface of the anterior component with a reference surface of the support structure, joining the anterior component to the support structure, and forming a primary space between an anterior surface of the support structure and the posterior surface of the anterior component insertion portion. In accordance with various embodiments, the anterior surface of the optical device support component comprises a gas permeable material, and the primary space formed during the method is configured to permit communication of a gas with at least a portion of the anterior surface of the support structure.

[0072] In accordance with various embodiments of a method as disclosed herein and with reference to Figure 2, an anterior component can comprise a component such as anterior component 106 having the various features previously described with reference thereto. Likewise, a support structure can comprise one or more components, such as first posterior component 102 as a first support structure component and posterior support component 104 as a second support structure component. A third support structure of a method in accordance with various embodiments can comprise a component such as first posterior component 602 (Figure 6).

[0073] In various embodiments, inserting an anterior component can comprise aligning an insertion portion of the anterior component with the receiving portion of the support structure and pressing the anterior component into the support structure. A method can further comprise aligning a reference surface of the anterior component with a corresponding and/or complementary reference surface of the support structure. Aligning a reference surface can comprise aligning one or more sets of reference surfaces, and can further comprise aligning one or more sets of reference features that may or may not be disposed on or in a reference surface. In various embodiments, the inserting step can proceed until one or more sets of complementary reference surfaces come into contact with one another and provide a positive stop (i.e., provide physical interference) to the progress of the inserting step.

[0074] A method in accordance with various embodiments can further comprise joining two components, such as joining the anterior component to the support structure. Joining can comprise any type of association between the anterior component and the support structure, such as an interference fit, adhesive bonding, welding, or the like.

[0075] In various embodiments, a method can further comprise forming a primary space, such as primary space 1 10 (Figure 2) or 610 (Figure 6), having the features of a primary space previously described herein. The primary space can be formed by inserting and aligning the anterior component with the support structure, as described above, or the primary space can be formed by inserting and aligning a third support structure component, such as first posterior component 602 (Figure 6).

[0076] In various embodiments, mating the oxygen permeable first support structure component to the non-permeable second support structure component can create a peripheral space between the components. Furthermore, the oxygen permeable first support structure component can be configured with portals to permit communication of a gas between the peripheral space and the primary space, as described previously with respect to optical device blanks 200 and 600.

[0077] In accordance with various embodiments and as noted briefly above, multicomponent optical devices may be manufactured using 3D printing and other additive processes, such as for example, those disclosed in Application No. WO/2015/151004 entitled "ADDITIVE MANUFACTURING OF MOLDS AND METHODS OF MAKING MOLDS AND DEVICES THEREFROM," which is incorporated by reference herein in its entirety.

[0078] Additionally, 3D printing of microlenses may be implemented in connection with the multicomponent optical devices disclosed herein. For example, by combining ultra-short laser pulses of a femtosecond laser with optical photoresist, microlenses such lenses may be manufactured with "conventional" shapes, or more labyrinthine shapes, which may in turn be embedded individually or in an array within contact lenses such as those disclosed herein. In various embodiments, the femtosecond laser may be focused using a microscope, and its pulses are sent into a liquid photoresist placed on a substrate such as an optical fiber or a glass substrate. Photons of the femtosecond laser beam are absorbed and expose the photoresist, crosslinking and hardening the polymer. The substrate can then be turned over and the other side of the lenses printed thereon. After removing unexposed photoresist, for example, with a solvent, the remaining hardened, transparent polymer forms the microlens. The resulting lenses are sufficiently small and sufficiently accurate, that it is possible for multicomponent optical systems such as disclosed herein to contain more than one microlens in a given contact lens.
