[0005]In accordance with embodiments, a method of making a face mask for a face of a human user can include determining a lower eye region bound. For example, the lower eye region bound can be determined by locating a position of one or more of a lowest extent of one or more lower eyelashes of the at least one eye when the eye is open, a lower bound of the eyeball as determined by a peak point of an arc of concavity in the lower eyelid of the at least one eye when the eye is closed, and a lowest extent of one or more upper eyelashes of the at least one eye when the eye is closed. The method can further include determining an upper eye region bound. For example, the upper eye region bound can be determined by locating an upper bound of the eyeball as determined by a peak point of an arc of concavity in an upper eyelid region of the at least one eye when the eye is closed. The eye height is defined by the distance between the lower eye region bound and the upper eye region bound. The method also includes defining the at least one eye opening such that, when the mask is fitted to the face, the first edge is disposed 0 mm to about 10 mm below the lower eye region bound and the second edge is disposed 0 mm to about 10 mm above the upper eye region bound. The method can also include creating the face mask having the at least one eye opening.

[0035]As used herein the term flexible means that a three-dimensional geometry of an element or the applicator in its entirety may be altered without any permanent deformation of the element's geometry. Applicator is also interchangeable used herein with “face mask” or “mask.”
[0036]Referring to FIGS. 1A-1C, the eye region 10 of the human face includes an eyeball 12 covered in part, on the bottom by a lower eyelid 14 and on the top by an upper eyelid 16. The lower and upper eyelids 14, 16 each have an inner eyelid liner 18, 20 adjacent the eyeball 12. From the eyelid liners 18, 20 extend lower and upper eyelashes 22, 24. The eye region 10 further includes a medial canthus 26 and a lateral canthus 28. The eyebrow 30 is situated above the upper eyelid 16.
[0037]The bounds of the eyeball 12 can be visually determined externally on the upper and lower eyelids 14, 16. Referring to FIGS. 1A and 1C, the lower bound of the eyeball 12 is disposed at the peak point 32 of an arc of concavity 32 in the lower eyelid 14. Referring to FIGS. 1B and 1C, the upper bound of the eyeball 12 is disposed at the peak point 34 of an arc of concavity 34 in the upper eyelid 16. FIG. 1D is a side view illustrating the concavity in the upper and lower eyelid 14, 16 resulting from the bounds of the eyeball 12.
[0038]As used herein, the “height of the eye HE” refers to the maximum distance between the lower eye region bound 66 and the upper eye region bound 68.
[0039]Referring to FIG. 2, a nose region 36 can include a central nose tip 38, first and second nostrils 40, 42, and a columella separating the first and second nostrils 40, 42.

[0041]Referring to FIG. 14, conventional face masks 200 are typically flat, two-dimensional masks 200 with one-size fits all eye openings 202 and spacing. Such masks 200 also typically have a one-size fits all opening for the mouth 204 and nostrils 206. When worn, conventional mask 200 do not align well with eyes, and other features of the human face of many users. With respect to the eye region, such conventional, ill-fitting masks 200 can cause discomfort by resting on the eye or covering the eye and/or causing ineffective treatment because the opening overlies the under-eye region to be treated rather than the mask surface having the active, cosmetic, and/or therapeutic agent. Similarly, in the mouth region, ill-fitting masks 200 can either overlap with the lip area or be spaced too far from the lips or nose portions thereof. In the region, ill-fitting masks 200 can interfere or overlap with the nostrils. The methods in accordance with various embodiments of the disclosure advantageously provide custom-fit openings that can allow the mask 200 to align properly, for example in the eye region resulting improved comfort and fit.
[0042]Referring to FIG. 6, in accordance with embodiments, the methods in accordance with embodiments of the disclosure can provide a mask 100 having an eye opening 102 that can have a lower peripheral edge, first edge 104, that lies close to the inner eyelid liner 18 of the lower eyelid 14 of the user, thereby allowing improved coverage of the under-eye region by the mask 100 portion having an active, cosmetic, and/or therapeutic agent disposed thereon. In accordance with other or further embodiments, the methods in accordance with the disclosure can provide a mask 100 having a pair of eye openings 102 that are spaced such that each opening lies at a desired, close, but non-overlapping position from the medial canthus 26. In accordance with other or further embodiments, the methods in accordance with the disclosure can provide a mask 100 having a nose opening 114 that overlaps partially with the outer nostril walls 46, 48, but does not interfere with the nostrils 40, 42 or cause discomfort when breathing. In accordance with other or further embodiments, the methods in accordance with the disclosure can provide a mask 100 having mouth opening 124 that is spaced close to the vermillion border 56 of both the upper and lower lips 52, 54. In accordance with embodiments of the disclosure, masks and methods of making the same can include any combination of custom-defined openings and/or standard-sized (universal fit) openings. For example, a mask can include a custom-defined mouth opening in accordance with embodiments of the disclosure with standard-sized eye openings. For example, a mask can include custom-defined eye opening in accordance with embodiments of the disclosure with standard-sized nose and/or mouth openings. For example, a mask can include a custom-defined nose opening in accordance with embodiments of the disclosure, with no openings for eyes or mouth. For example, the mask can include custom-defined eye, mouth, and nose openings in accordance with embodiments of the disclosure. Any other such combinations of defined openings are contemplated herein.
[0043]The methods and masks 100 in accordance with embodiments of the disclosure provide improved fit and comfort. Improved fit can allow for better contact of the active, cosmetic, and/or therapeutic agents on the mask 100 with desired regions of the face. Desired regions can include one or more of, for example, the under-eye region, the corners of the nose 45 just outboard the outer nostril walls 46, 48, and the skin close to the lips. Improved fit can include masks 100 that cover such desired regions, while not foregoing coverage of other regions, such as above the eye, and/or without interfering with facial features where coverage is to be avoided, such as the eyeball 12, nostril 40, 42, and/or lips 52, 54. Mask 100 in accordance with embodiments of the disclosure can also have improved fit in not only contacting desired regions, but maintaining closer contact without gaps or bubbles in the mask 100 that would disrupt contact with a desired region.

In such embodiments, defining the at least one eye opening 102 can include defining a peripheral curve that intersects at a first edge 104 through the first, third, and fourth anchor points, and at a second edge 106 through the second, third, and fourth anchor points. In various embodiments, additional anchor points can be used.
[0051]In various embodiments, the method can include or further include determining a position of the medial canthus 26 and a position of the lateral canthus 28 and defining the eye opening 102 such that corners 110, 112 of the eye opening 102 are spaced about 0 mm to about 10 mm outbound, relative to the eyeball 12, from the medial and lateral canthus 26, 28, respectively. Unless otherwise specific, as used herein, “outboard of the medial canthus 26” or “outboard of the lateral canthus 28” refers to positioning outboard from the respective canthus relative to the position of the eyeball 12. That is, the eyeball 12 is considered inboard of the respective canthus.
[0052]In various embodiments, the method can include obtaining a digital geometric representation of the face of the user. FIG. 5 illustrates one embodiment of obtaining such a digital representation. Any known methods of obtaining a digital representation of an object, such as a face, or converting images to digital geometric representations can be used. In various embodiments, the method can include one or more of displaying, storing, and transmitting of the digital representation or data associated therewith. Any known processes, storage media, and display systems and equipment can be used.
[0053]Referring to FIG. 6, in accordance with an embodiment of the disclosure, a mask 100 can include an eye opening 102 defined in accordance with embodiments of the method of the disclosure. As illustrated in FIG. 6, the mask 100 can further include a mouth opening 124 and/or nose opening 114 as discussed in detail below.
[0054]Referring to FIG. 7A, a mask 100 in accordance with various embodiments of the disclosure can have an eye opening 102 having first and second opposed curve edges 104, 106 with the height HEO extending between the edges 104, 106. The first edge 104 can be disposed about 0 mm to about 10 mm below the lower eye region bound 66. The second edge 106 can be disposed about 0 mm to about 10 mm above the upper eye region bound 68. The height HEO of the eye opening 102 can be defined by the maximum distance between the first edge 104 and the second edge 106. In various embodiments, the mask 100 can have an eye opening 102 height HEO at least equal to the height of the eye HE.
[0055]A mask 100 in accordance with embodiments of the disclosure can have a first edge 104 of an eye opening 102 that is disposed about 0 mm to about 10 mm below a lower eye region bound 66 when the mask 100 is worn. In accordance with various embodiments, the eye opening 102 can include second edge 106 that is disposed about 0 mm to about 10 mm above the upper eye region 10 bound 68 when the mask 100 is worn.
[0056]In various embodiments, the mask 100 can include or further include an eye opening 102 having first and second corners (also referred to as side edges) 110, 112 that are spaced from the medial and lateral canthus 26, 28, respectively, about 0 to about 10 mm outboard, from the medial and lateral canthus 26, 28. The spacing of the first and second corners 110, 112 from the medial and lateral canthus 26, 28, respectively, can be the same or different.
[0057]In any of the embodiments herein, the mask 100 or method of making a mask 100 can include defining the mask 100 to have first and second eye openings 102 corresponding to both eyes of the user.
[0058]In various embodiments, the mask 100 or method of making a mask 100 can include defining a registration feature in the mask 100 to aid in aligning the mask 100 when worn. For example, in embodiments, the registration feature can be a portion of the mask 100 covering one or more of the nose or portion thereof, the chin or portion thereof, and a jaw section. Inclusion of coverage of such portions of the mask 100 can aid the users in aligning the mask 100 upon application such that the openings of the mask 100 properly align with the target region.
[0059]In accordance with embodiments, the method can further include determining the relative spacing between the eyes of the users and defining a mask to have a spacing that is within 0 mm to 10 mm of the spacing between the eyes of the user. The spacing between the eyes of a user can be defined as the spacing between the medial canthus 26 of each eye and the spacing between the eye openings of the mask can be defined between the first corners of each eye opening. In embodiments, the method can further include determining the relative spacing between one or more features to which an opening is to be defined. For example, where a mask 100 is being created to have an eye opening and a mouth opening, a spacing between a feature of the mouth and a feature of the eye can be determined and the mask can be defined to have a spacing that is about 0 mm to about 10 mm of this spacing, with the mask spacing between defined between features or bounds of the opening disposed adjacent the selected features of the eye and mouth. Such determination of relative spacing of facial features and associated openings can be done with any openings and target areas. For example, relative spacing between nostrils or the base of the columella and the upper lip can be used to define spacing between the upper bound of the mouth opening and lower bound of the nose opening. In some embodiments the pupillary distance (PD) or interpupillary distance (IPD) may be used to determine relative spacing between the eyes.
[0060]In any of the embodiments disclosed herein, the mask 100 can be a two-dimensional mask or a three-dimensional mask. In accordance with embodiments, a two-dimensional mask can be a substrate mask, nonwoven mask, woven mask, knit mask, paper mask, cotton mask, any other type of woven, nonwoven, gel, hydrogel type of mask made of natural or synthetic fibers, composites, gel, hydrogels, films, apertured films or any other such mask making materials as is known in the art. In any of the embodiments disclosed herein, the three-dimensional mask can be a self-supporting mask. As used herein, the term “self-supporting” means that an element of or the applicator in its entirety retains a substantial portion of a defined three-dimensional shape without the aid of external support structures when resting on a horizontal surface in air. In any embodiment, the mask may be a semi-three dimensional mask where cuts, folds, or seams are used in a flat substrate material to create a less flat or more three-dimensional mask. In any of the embodiments disclosed herein, the mask can be a single-dose applicator or for single use having a single dose of the active, cosmetic, and/or therapeutic. As used herein, the term single-dose means an applicator comprising sufficient active agents to afford a user only a single application of the active agent via the applicator. In any of the embodiments disclosed herein, the mask can be for multiple use. For example, active, cosmetic, and/or therapeutic agents can be applied and successively reapplied for multi-use. In any of the embodiments disclosed herein, the mask can be disposable. As used herein, the term disposable refers to applicators intended to be discarded after use rather than durable, or semi-durable implements intended for multiple users either with or without the reapplication of an active agent. In any embodiment, the mask can be a durable item suitable for washing by hand or in a dishwasher or clothing washing machine.
[0061]In various embodiments, the lower eye region bound 66 can be defined at one or more of the lowest one of the lowest extent of one or more lower eyelashes 22 of the at least one eye when the eye is open, a lower bound of the eyeball 12 as determined by a peak point 32 of an arc of concavity in the lower eyelid 14 of the at least one eye when the eye is closed, and a lowest extent of one or more upper eyelashes 24 of the at least one eye when the eye is closed. For example, in embodiments, the peak point 32 of an arc of concavity in the lower eyelid 14 can be determined manually by rotating a three-dimensional image of the face or eye region thereof and digitally altering the angle of the light to estimate the location of the peak point 32 of the arc of concavity. In embodiments, for example, the peak point 32 of the arc of concavity in the lower eyelid 14 can be determined by taking cross-sections in a three-dimensional image of the face or eye region, perpendicular to the direction of the curvature that is vertically from the forehead to chin and observing the lowest point in the cross-section. The cross-sections can be taken at one or more reference points in the eye region to define points which are then connected to form the arc of concavity defining the eye boundary. In yet other embodiments, an algorithm, such as a machine learning algorithm, neural net, or deep learning algorithm can be used to teach a software tool to identify the peak point 32 of an arc of concavity on a digital representation of the face or at least the eye region thereof.
[0062]For any of the reference points or anchor points disclosed these may be identified manually or through a machine learning algorithm, image analysis, or other approach, for example facial landmark detection such as Dlib (available from github). Reference points or anchor points may be determined in part through an app and or by a user. Pixels in a 2D image or 3D information may be used to select the anchor points through edge finding algorithms, feature extraction, using texture, color, RBG or grayscale values, shadows, or other features from a 2D image or 3D surface. In various embodiments, the lower eye region bound 66 is the lowest one of the lowest extent of one or more lower eyelashes 22 of the at least one eye when the eye is open. In some embodiments, the lower eye region 66 bound is the lower bound of the eyeball 12 as determined by a peak point 32 of an arc of concavity in the lower eyelid 14 of the at least one eye when the eye is closed. In some embodiments, the lower eye bound is the upper most one of the lowest extent of one or more lower eyelashes 22 of the at least one eye when the eye is open.
[0063]In various embodiments, the lower eye region bound 66 is the lowest extent of one or more lower eyelashes 22 of the at least one eye when the eye is open. For example, the lower eye region bound 66 can be the lowest extent of the longest one of the lower eyelashes 22 of the at least one eye. Alternatively, the lower eye region bound 66 can be defined at an average of the lowest extents of each of the lower eyelashes 22.
[0064]FIGS. 7A and 7B illustrate an embodiment of the mask 100 and method of the disclosure in which the lower eye region bound 66 is selected to be the peak point 32 of an arc of concavity in the lower eyelid 14 of the at least one eye when the eye is closed. FIG. 8 illustrates an embodiment of the mask 100 and method of the disclosure in which the lower eye region bound 66 is selected to be the lowest extent of one or more lower eyelashes 22 when the eye is open.
[0065]In various embodiments, the eye opening 102 of the mask 100 has or is defined to have a first edge 104 that is arranged to contact or have a defined spacing from the lower eye region bound 66 when the mask 100 is worn. The first edge 104 of the eye opening 102 can be positioned from about 0 mm to about 10 mm below the lower eye region bound 66. For example, the first edge 104 of the eye opening 102 can about 0 mm to about 10 mm, about 1 mm to about 4 mm, about 0 mm to about 5 mm, about 2 mm to about 6 mm, about 1 mm to about 8 mm, and about 5 mm to about 10 mm. In various embodiments, the first edge of the eye opening 102 can be about 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, or 10 mm below the lower eye region bound 66. In various embodiments, the lowest point of the first edge 104 of the eye opening 102, farthest from the lower eye region bound 66 can be used as the reference point for measuring the distance between the lower eye region bound 66 and the first edge 104 of the eye opening 102.
[0066]Positioning of the first edge 104 of the eye opening 102 about 0 to 10 mm from the lower eye region bound 66 can advantageously provide an eye opening 102 that has tight fit to the eye, allowing maximum coverage of the under-eye region, without causing discomfort by interfering with the lower eyelashes 22 or overlapping too closely with the edge of the lower eyelid 14.
[0067]In embodiments, the upper eye region bound 68 can be determined by locating an upper bound of the eyeball 12 as determined by a peak point 34 of an arc of concavity in an upper eyelid of the at least one eye when the eye is closed. The mask 100 can have an eye opening 102 that is positioned when worn such that the second edge 106 is at or above the upper eye region bound 68. Eye openings 102 positioned at or above the peak point 34 of an arc of concavity in the upper eyelid have been found to have improved comfort to the user, as the mask 100 does not rest on the upper eyelid 16 in such a way to interfere with movement of the eyelid or eyeball 12.
[0068]In various embodiments, the second edge 106 can also or alternatively be spaced to be at or above the highest extent of the upper eyelashes 24 when the eye is open. In various embodiments, the highest extent of the upper eyelashes 24 can be the highest extent of the longest one of the upper eyelashes 24 of the at least one eye. Alternatively, the highest extent of the upper eyelashes 24 can be the average of the highest extents of each of the upper eyelashes 24.

[0071]In accordance with embodiments of the disclosure, the method can include obtaining one or more digital geometric representations of at least one eye region 10 of the user's faces. The digital geometric representations can include variations in which the user's eye is open and the user's eye is closed. The digital geometric representation can include images or scans representing front profiles and/or side profiles of the user. In various embodiments, the digital geometric representation can be of the entire user's face or of the entire eye region 10, including both eyes or any portion of the user's face including at least one eye region 10.
[0072]The digital geometric representation can be obtained, for example, by any one or more of 3D scanners, 2D scanners, cameras, smartphone camera, digital applications for tablets and phones, and other known equipment for obtaining digital geometric data. An Artec Spider, available from Artec Group Palo Alto, CA is an example of a suitable 3D scanner. An example mobile application for a cellular phone or table is 123D Catch from Autodesk or Capture: 3D Scan Anything” by developer, Standard Cyborg or Bellus3D FaceApp by Bellus3D Inc. or the TrueDepth camera system form Apple.
[0073]The digital geometric representation of the human face or portion thereof can be used as a whole or partitioned with only a portion of the total representation being used. Furthermore, portions of the geometry derived from the scan or other imaging technique can be removed or edited from the digital geometric representation. The digital geometric representation data may be used without alteration, or the geometry of the representation may be altered. For example, digital processing may be used to alter the digital data. For example, the digital data can be altered to be provided as a mesh to allow for measurement of various features on the digital data. For example, a two dimensional set of data from an image or scan can be altered to provide a three-dimension representation of the two-dimensional data.
[0074]In any of the embodiments of the disclosure, any one or more of the various digital processing equipment, digital geometric representations, graphics programs, and graphical displays may be stored in a tangible computer readable memory or medium and/or shared or cloud-based medium, and execute one or more processors to perform the functions described herein. For example, in embodiments, the digital geometric representation can be obtained by a user using a smartphone camera and/or mobile application and subsequently uploaded to a manufacturer's shared memory or medium for manufacturing of the mask 100. In other embodiments, digital geometric representations can be obtained with scanners or other imaging devices located at the point of sale of the mask 100. The data from the digital geometric representations can be stored locally or on a shared medium.
[0075]In various embodiments, the lower and upper eye region bounds 66, 68 are defined using the digital geometric representation. Various graphics programs can be used for obtaining measurements and manipulations of the data of digital geometric representation. For example, Blender, by Blender Foundation can be used to view, manipulate, and/or modify the digital geometric representation data. In various embodiments, the digital geometric representations can be used to define anchor points corresponding to the lower and upper eye region bounds 66, 68. The methods in accordance with embodiments of the disclosure include defining at least two anchor points for an eye opening 102. In some embodiments, the method can include defining more than two anchor points. For example, in embodiments, the method can include defining four anchor points corresponding to the upper eye region bound 68, lower eye region bound 66, medial canthus 26, and lateral canthus 28. Any suitable number of anchor points can be defined.
[0076]In various embodiments, the anchor points are used to define the peripheral edges of the eye opening 102. As described herein, the anchor points can be set at or offset a distance from the respective target feature of the eye. For example, an anchor point can be about 0 mm to about 10 mm below an anchor point corresponding to the lower eye region bound 66. For example, an anchor point can be about 0 mm to about 10 mm above an anchor point corresponding to the upper eye region bound 68. In any of the embodiments, an anchor point can be off-set about 0 mm to about 10 mm from the respective target feature of the eye region.
[0077]Once the at least two anchor points are defined, the method can include fitting one or more curves to the anchor points. For example, a Bezier curve can be used to fit curves corresponding to the peripheral edges of the eye opening 102 to the at least two anchor points. In any embodiments disclosed herein one or more of the following can be used to connect or touch anchor points for defining an opening: Bezier curves, linear segments, parabolas, concave curves, regular or irregular curves, and polygons. In various embodiments, the connector, which defines the edge of the opening can be curved or can have any of the shapes described above. In various embodiments, the connector can mimic, follow, or parallel in whole or in part curvatures and pathways of the underlying physiology of a feature in the target region. For example, the connector can mimic, follow, or parallel the curvature of an eye brow, and eye fold, or an eye shape. Such mimicking, following, or paralleling can aid in conforming the opening to a particular user's face functionally and can provide a more aesthetically pleasing wear experience. In other embodiments, a curve can be defined on the digital geometric data from the curvature of the lining of the upper and lower eyelid and digitally shifted to intersect with the anchor point. Other methods of fitting curves to points can be used as is known in the art. In embodiments using a Bezier curve, a curve can be digitally overlaid over the digital representation in the eye region 10 and handles of anchor points can be adjusted in succession until the curve follows the points of lowest curvature tracing the underlying eyeball 12 and intersect the anchor points.
[0078]Once the curve of the eye opening 102 is defined digitally, the data can be exported in any suitable file format to be used in creating the mask 100. For example, the curve can be converted to a mesh using a series of segments that allows for export to cutting tools or other digital tool for printing the mask 100 or defining a mold for making the mask 100. For example, the data of the curve can be converted to mesh and exported as a DXF file. When converting the curve
