- Embodiments of the present invention generally relate to eye masks and kits for treating and/or preventing periorbital puffiness, to methods of manufacture thereof, and to methods of treatment using such eye masks and/or kits.
- the eye mask has two side portions extending from a bridge portion. Each side portion includes an orbital region, and an infraorbital region that is configured to apply pressure to a corresponding infraorbital region of the face when the eye mask is attached to the face of the user. Accordingly, when the eye mask is in place, compression is applied to the areas of the face that are susceptible to puffiness.
- this targeted compression effect has been found, when the mask is worn during sleep, to reduce puffiness in individuals suffering therefrom. It has also been found to be effective in preventing the occurrence of puffiness.
- the advantageous effect of the invention can be achieved in as little as a single overnight use for prevention of eye bags.
- FIGS 1 and 2 show an example of an eye mask 10 according to certain embodiments.
- the eye mask 10 includes a mask body including a bridge portion 12 from which extends, on either side, a first side portion 14 and a second side portion 16.
- First side portion 14 may include an aperture 13 near an extremity thereof
- second side portion 16 may include an aperture 15 near an extremity thereof.
- Apertures 13, 15 may be used to attach a retaining component, such as a band or strap (not shown), for securing the eye mask 10 to a face of a user.
- the band may be attached to side portions 14, 16 in other ways, such as by staples, adhesives, or heat-sealing.
- the band is preferably elastic, and adjustable to accommodate different head shapes while maintaining the compression effect.
- an elastic band achieves a good compression effect while still ensuring comfort
- First side portion 14 includes an orbital region 18 adapted to cover the right eyeball of the user, and an infraorbital region 24 (below orbital region 18) that is configured to apply pressure to a corresponding infraorbital region of the face when the eye mask 10 is attached to the face of the user.
- second side portion 16 includes an orbital region 20 adapted to cover the left eyeball of the user, and an infraorbital region 26 that is configured to apply pressure to a corresponding infraorbital region of the face (also referred to herein as the eye bag region) when the eye mask 10 is attached to the face of the user.
- an orbital region 20 adapted to cover the left eyeball of the user
- an infraorbital region 26 that is configured to apply pressure to a corresponding infraorbital region of the face (also referred to herein as the eye bag region) when the eye mask 10 is attached to the face of the user.
- the side portions 14, 16 can have a thinner cross-section compared to the bridge portion 12.
- the orbital regions 18, 20 can have a thinner cross-section compared to the bridge portion 12.
- the orbital regions and the infraorbital regions can have different thicknesses.
- the orbital regions 18, 20 of the side portions 14, 16 can have a thinner cross-section compared to the infraorbital regions 24, 26.
- the infraorbital regions are made to be thicker than the orbital regions. This increases the rigidity under the eye area for better compression.
- the retaining component may be adjustable to vary the pressure applied by the infraorbital regions 24, 26 of the eye mask 10.
- the retaining component may be a strap having first and second portions that are secured to each other by a fastener such as a hook-and-loop fastener, where the first portion carries hooks (or loops) and is attached to one side portion 14 of the eye mask 10 and the second portion carries loops (or hooks) and is attached to the other side portion 16.
- the components of the hook and loop fastener may both be carried on one portion that is looped through the other portion and back on itself, for example.
- a strap may be formed as a single component having a hook portion on one surface and a loop portion on the opposite surface, wherein the strap is connected to the first side portion 14 and looped back on itself through part of the second side portion 16 (for example, through an aperture 15) to engage the hook portion with the loop portion.
- the hook portion and loop portion may extend along a substantial part, or the entire length, of the strap to enable greater adjustability.
- the retaining component is appropriately sized to provide sufficient tension for holding the eye mask in position.
- the tension in the retaining component may be adjustable, for example by way of one or more straps or the like as mentioned above.
- the retaining component keeps the eye mask in place, for example during restless sleep, without discomfort while the user is lying on their side.
- the infraorbital regions 24 and 26 of the eye mask 10 are configured according to the user's face shape.
- the user's face shape may be determined by a three-dimensional (3D) scan, such as by using a Face Camera Pro of Bellus 3D, Inc.
- the 3D scan may be performed at the end of the day, when the periorbital region tends to be less swollen.
- the 3D facial scan data may be analysed to determine the outer limits of the eye ball, and subsequently to generate a mask design that substantially matches the contours of the user's face, particularly in the infraorbital regions, such that when the mask 10 is worn and retained in place with the infraorbital regions 24, 26 contacting the corresponding infraorbital regions of the user's face, the infraorbital regions 24, 26 apply gentle pressure in the areas where swelling tends to occur. Accordingly, wearing the mask 10 overnight produces a compression effect that tends to reduce periorbital puffiness.
- the eye mask 10 may have an internal (i.e., face-contacting) surface 30 that has a relatively flat profile in the infraorbital region 24.
- the eye mask 10 may be particularly suitable for prevention of eye bags.
- the eye mask 10 may be configured to be suitable for treatment of existing eye bags.
- a facial scan of the user may be obtained to determine the contours in the infraorbital region.
- An eye mask 10 may be produced with an infraorbital shape that accommodates the determined contours, but is designed to apply compression to the eye bag.
- the infraorbital region 44 is outwardly recessed or indented (i.e., in a direction away from the user's face) so as to include one or more convex protrusions corresponding to the existing eye bag.
- the convex protrusion(s) at the infraorbital region 44 allows pressure to be applied to a corresponding infraorbital region of the face when a user suffers from periorbital puffiness, for example in the morning, following surgery or due to an underlying medical condition.
- the convex shape accommodates the pre-existing eye bag with the inner surface of infraorbital region 44 contacting the eye bag so as to apply gentle compression to it when the eye mask is attached to the face of the user.
- a mask with a protrusion which is less convex i.e., flatter
- a mask with no protrusion as shown in Figure 4
- An example of a series of such masks that is used to progressively flatten eye bags is shown in Figure 11 and described in further detail below.
- the indented or recessed infraorbital region 44 may have a depth between about 3 mm and 20 mm relative to the infraorbital region 24, such that varying degrees of compression may be applied, with smaller depth producing greater compression.
- each infraorbital region 24, 26 of the eye mask includes an elongate compression region, for example a substantially crescent-shaped region.
- An elongate compression region provides greater contact surface area, and thus more consistent pressure during use.
- the bridge portion 12 is shaped such that it substantially conforms to the contours of a nasal region of a subject.
- the bridge portion 12 can cover a substantial area of the nasal region, or at least a portion of the nasal region.
- the b ridge portion can be a nose clip.
- the bridge portion 12 may be more rigid than the side portions 14, 16. This helps to reinforce the compression effect on the infraorbital regions when the user wears the mask 10.
- the bridge portion 12 may be made from a more rigid material than the side portions 14 and 16.
- the bridge portion 12 may be made of the same material as the side portions 14, 16, but may have a greater thickness than the side portions 14, 16. Where the mask 10 is formed by 3D printing, this may be achieved by, for example, printing additional layers of material in the bridge portion 12.
- the bridge portion can be thickened such that it can provide structural balance and support.
- the bridge portion can have a thickness of about 1 mm to about 10 mm, about 1 mm to about 8 mm, about 1 mm to about 6 mm, or about 1 mm to about 4 mm.
- the bridge portion 12 can further provide a compression force acting on both sides of a dorsum nasi of the nasal region. This provides a further advantage of keeping the eye mask in position when in use. To this end, when manufacturing the eye mask, the bridge portion can be fabricated to be slightly narrower than the nasal region of a subject.
- the eye mask 10 (as well as other embodiments of eye masks described below) may be used in different applications.
- the eye mask 10 may be used as a "preventative" mask for users suffering from early-morning eye swelling.
- a preventative mask has a shape conforming to the user's normal face shape during the day, to create a targeted compression effect to prevent fluid from leaking into the subcutaneous tissue at night time.
- the preventative mask aims to keep the face shape in comformity with that determined from an original face scan of the user corresponding to the user's "normal" face shape.
- a "treatment" mask or set of masks can be provided for users with existing (usually familial) eye bags.
- a first mask targets compression based on the initial shape of the eye bags, and subsequent masks may gently increases pressure by providing successively less convex (flatter) infraorbital regions, which gradually and progressively reduce the swelling.
- An example of a kit containing treatment masks is depicted schematically in Figure 11.
- a first mask 10.1 of a series of n masks has convex protrusions in the infraorbital regions 24.1 and 26.1.
- a subsequent mask 10.2 has flatter convex protrusions than those of mask 10.1, in infraorbital regions 24.2 and 26.2.
- an n th mask 10 10.
- the eye mask 10 (or any other eye masks disclosed herein) may be configured for treatment of periorbital puffiness by being shaped in the infraorbital regions to produce targeted pressure in a generally upward direction (e.g. from below the infraorbital region towards the infraorbital or orbital region), or straight on (horizontally), or from the edges of the eyebag inwards (towards the nose), or a combination of two or more of these.
- FIG 3 an alternative embodiment of an eye mask 100 is shown.
- the side portions 114, 116 in Figure 3 are integral with the bridge portion 112 such that the mask 100 is formed as a single piece. It will be appreciated, though, that at least part of the side portions 114, 116 may instead be rigidly coupled to the bridge portion 112 by appropriate fastening means.
- First side portion 114 includes an orbital region 118 that is adapted to cover a right eyeball of the user, and an infraorbital region 124 that is configured to apply pressure to a corresponding infraorbital region of the face when the eye mask 100 is attached to the face of the user.
- Second side portion 116 includes like orbital and infraorbital regions (for the user's left eye) that are not shown in Figure 3.
- the infraorbital region of the second side portion 116 is configured to apply pressure to a corresponding infraorbital region of the face (also referred to herein as the eye bag region) when the eye mask 100 is attached to the face of the user.
- the eye mask 100 may include at least one through-hole 102 (in this case, a plurality of through-holes 102, 104, 106) to assist with breathability and to thus increase the level of comfort for the wearer.
- the eye mask 100 has a bridge portion 112 from which first side portion 114 and second side portion 116 extend.
- First side portion 114 may include an aperture 113 near an extremity thereof
- second side portion 116 may include an aperture 115 near an extremity thereof.
- Apertures 113, 115 may be used to attach a retaining component, such as a band or strap (not shown), for securing the eye mask 100 to a face of a user.
- the band may be attached to side portions
- the through-holes 102 improve breathability surrounding the eye areas and allows for oxygenation of the retina.
- the through-holes 102 can have a diameter of about 0.5 mm to about 10 mm. In certain embodiments, the through-holes 102 have a diameter of about 0.5 mm to about 2 mm.
- the through-holes can extend to the extremities of the eye mask.
- parts of the first side portion 114 and/or the second side portion 116 may be formed as a mesh or micromesh to achieve better breathability.
- the through-holes can be arrayed.
- An array of through-holes 102 is formed in the first side portion 114.
- an array of through-holes 106 is formed in the second side portion 116.
- An array of through-holes 104 is also formed in the bridge portion 112.
- Forming arrays of through-holes in each portion of the mask 100 both increases breathability and reduces the weight of the mask 100, thus further aiding user comfort.
- the spacing between the through-holes in the array can be regulated in order to maintain the sturdiness of the eye mask. It was found that the maintaining the spacing to be within a range can be further advantageous for forming an eye mask which is less prone to breakage.
- the spacing can be from about 3 mm to about 15 mm, about 3 mm to about 12 mm, about 3 mm to about 10 mm, about 3 mm to about 8 mm, or about 3 mm to about 6 mm. It will be appreciated, though, that holes could be formed in just one of the mask portions 112, 114, 116, for example, or just in the side portions 114, 116, in particular in the orbital regions 118 for example.
- Aeration holes 102, 104, 106 may be included in the mask 100 using FFF and SLS printers, simply by omitting printing material in the respective hole locations.
- the holes may be printed using a secondary soluble material (e.g., PVA, and the like) when printing using FFF printers, after which the soluble material is removed by washing in water.
- a secondary soluble material e.g., PVA, and the like
- the orbital regions 18, 20, 118, and/or 120 may be offset to improve user comfort.
- orbital region 18 may be adjusted such that it bulges outwardly, i.e. projects further away from the internal (face-contacting) surface 40 of the eye mask 10.
- the 3D facial scan data may be adjusted such that the orbital region 18 is offset by between about 5 mm and about 7 mm, and thus does not contact the orbital region of the user's face when the mask 10 is worn, thus allowing for freer eye movement during REM sleep and improving user comfort.
- An exemplary adjusted orbital region 58 is shown in Figure 6, in which the original orbital region 18 is shown in dotted outline.
- the side portions of the eye mask may be made of a flexible polymer material.
- This material can be of a lower rigidity or lower shore A hardness than that used in the bridge portion.
- the flexible polymer material may be selected from the group consisting of thermoplastic polyurethane (TPU), polylactic acid (PLA), thermoplastic elastomer (TPE), plasticized copolyamide TPE (PCTPE), nylon, Acrylonitrile-Butadiene Styrene (ABS) and a combination of any two or more thereof.
- TPU thermoplastic polyurethane
- PLA polylactic acid
- TPE thermoplastic elastomer
- PCTPE plasticized copolyamide TPE
- ABS Acrylonitrile-Butadiene Styrene
- Agilus30 a PolyJet Photopolymer with superior tear- resistance and is capable of withstanding repeated flexing and bending can be used.
- the side portions 14, 16, 114, 116 may have a flexural strength of about 10 MPa to about 50 MPa.
- the material of the side portions 14, 16, 114, 116 may be characterised by shore hardness.
- Embodiments may have a shore A hardness in the range from around 10A to 100A.
- flexible filaments e.g., TPU, Recreus Filaflex, MatterHackers Soft PLA, NinjaTek SemiFlex, Polymakr Polyflex, FormFutura FlexiFil TPC, taulman3D PCTPE, and the like
- SLS Selective Laser Sintering
- the bridge portion 12 or 112 may be formed from a material that is more rigid than the material of the side portions 14, 16 (or 114, 116).
- the bridge portion 12 may be made of a material selected from the group consisting of polylactic acid (PLA), acrylonitrile butadiene styrene (ABS), nylon, and polycarbonate.
- the bridge portion 12 may have a flexural strength of about 50 MPa to about 100 MPa.
- the material of the bridge portion 12 may be characterised by its shore hardness.
- the bridge portion 12 may have a shore A hardness ranging from about 50A to 100A.
- FIGS. 7A and 7B another embodiment 200 of an eye mask is shown.
- Side portions generally indicated at 202 and 204, extend from a bridge portion 206.
- Side portion 202 includes an upper, flexible portion 203, and a lower, rigid, portion 213.
- side portion 204 includes an upper, flexible, portion 205 and a lower, rigid, portion 215.
- the lower rigid portions 213 and 215 are part of a frame structure 208 which includes bridge portion 206 intermediate the lower rigid portions 213, 215.
- the eye mask 200 has, at each of its sides, at least one elongate aperture 218 for receiving a retaining component, such as a strap, for securing the eye mask 200 to a user's head.
- a retaining component such as a strap
- the flexible upper portions 203 and 205 cover the orbital regions of the user when in use, while the rigid lower portions 213, 215 that are either side of bridge portion 206 include respective infraorbital regions 224, 226 that, being rigid, are configured to apply pressure to a corresponding infraorbital region of the face when the eye mask is attached to the face of the user.
- the orbital regions, which are generally indicated at 203a and 205a in Figures 7A and 7B, of the side portions 202, 204 are thus less rigid than the frame element 208.
- the infraorbital regions 224, 226 may be outwardly recessed or indented so as to include one or more convex protrusions, such as the infraorbital region 44 with convex protrusion shown in Figure 5.
- protrusions of varying depth at the infraorbital regions 224, 226 allow varying pressure to be applied to a corresponding infraorbital region of the face when the eye mask is attached to the face of the user.
- the upper portions 203, 205 are formed from a different material compared to the lower portions 213, 215 of frame element 208.
- the upper portions 203, 205 can be formed using a material with a lower rigidity and/or a lower shore A hardness than the frame element 208.
- this allows greater comfort to the user as, for example, it provides greater freedom of eye movement during, for example, REM sleep.
- the higher rigidity of the bridge portion 206 of frame element 208 allows the eye mask 200 to be held in position during sleep by, for example, resting on the dorsum nasi area of the nasal region of the user.
- the upper portions 203, 205 can be formed with a thinner cross-section compared to the bridge portion 206.
- the upper portions 203, 205 can, for example, have a thickness of about 0.2 mm to about 5 mm, about 0.2 mm to about 4 mm, about 0.2 mm to about 2 mm or about 0.4 mm to about 1 mm. This is further advantageous as it reduces the pressure on the eye of the subject, and accordingly provides greater comfort to the user. Additionally, the thinner, more flexible material also prevents or substantially reduces skin indentation along the edges of the eye mask 200.
- the lower portions 213, 215 provide the eye mask with a structural frame 'exoskeleton', which provides balance, limits movement at the nose bridge, and increases compression under the eye. Additionally, as the upper portions 203, 205 can be made using a less rigid (and possibly softer material), the perceived comfort by the user is expected be higher. This is due to the greater flexibility around the eyeballs while maintaining under and upper eye area compression.
- the orbital regions 203a, 205a are carried on a liner attached to the frame element.
- a liner 210 may be attached to frame element 208.
- the liner 210 may have a first part 210a and a second part 210b, where the first part 210a carries the orbital regions 203a, 205a, and the second part 210b is attached to the frame element 208.
- the second part 210b of the liner 210 is in contact with the infraorbital regions 224, 226 of the eye-contacting portions 202 and 204.
- Corresponding parts 224' and 226' of the liner in the second part 210b are aligned with the infraorbital regions 224 and 226. Likewise, a portion of the liner 206' is aligned with the bridge portion 206.
- the infraorbital regions 224, 226 can extend substantially to an extremity of the eye mask.
- the extension of the infraorbital region 224 or 226 can extend to a position near the apertures 218. While the infraorbital region is shown to extend to a position below the aperture 218 in Figure 7A, the extension can alternatively be above the aperture 218 or be both above and below the aperture 218.
- this provides additional strength to the eye mask such that it breaks or tears less readily.

- more masks may be required so that the compression effect is kept within reasonable limits to allow time for the skin to adjust.
- 10 mask profile sets might be created to get from the original data set to mask data set Z.
- a convex shape of the existing eye bags may be determined from the facial scan data, and then inverted and transformed into a matching shape using CAD, thus producing a mask design that will result in a compression effect when the subject wears the mask.
- an adjustable strap (such as a hook-and-loop belt) may be used to retain the mask on the user's head, with the user being able to adjust the tightness of the adjustable strap over time to gradually increase the compression effect and push the infraorbital region towards the desired facial contour.
- the 3D facial scan data may be modified such that the bridge portion of the mask design is thicker than the side portions.
- the 3D facial scan data may be modified to include one or more apertures in the mask design, such that when the mask design is printed, one or more through-holes are formed in the eye mask.
- An array of such holes may be included in the mask design.
- an active agent may be applied to the infraorbital region of the eye mask, either before or after attaching the retainer to the mask body.
- the active agent may be included in a coating or a liner.
- the active agent may be selected from the group consisting of a moisturiser, a coolant, anti-aging agent, anti-oxidant and a combination thereof.
