Description

Technical Field

[0001] The present invention relates to an eyeglass frame, eyeglasses having the eyeglass frame, and a method for designing the eyeglasses. More specifically, the present invention relates to an eyeglass frame suitable for wearing by pets, particularly pets having auricles, eyeglasses having the eyeglass frame, and a method for designing the eyeglasses.

Background Art

[0002] Since ultraviolet rays harmful to the human eye are naturally harmful to the eyes of pets such as dogs, pet sunglasses that meet the wishes of pet owners who want to protect their pets' eyes from ultraviolet rays are commercially available on Internet mail-order sites and the like. In addition to sunglasses, there is also a need for eyeglasses for pets suffering from eye diseases. Many of the commercially available pet eyeglasses are goggle-type as exemplified in Patent Document 1.

[0003] If a pet such as a beloved dog wears sunglasses like a human wears sunglasses and goes for a walk, etc., there will probably be many pet owners who find it interesting and cute. And it is obvious from the example of human eyeglasses that more diverse designs are possible for non-goggle-type, ordinary eyeglass types. Also, in view of the fact that pet clothes matching the owner are commercially available, there seems to be a need to put ordinary eyeglass-type, matching sunglasses, etc. on a pet such as a beloved dog.

[0004] Pet eyeglasses modeled after ordinary human eyeglasses that only consider fashionability are commercially available, but they are for the purpose of short-term wearing indoors, such as taking pictures. When sunglasses or the like are worn on a dog outdoors, in view of the up-and-down movement when the dog wearing them runs, those modeled after ordinary human eyeglasses are not suitable.

[0005] Patent documents 2 and 3 disclose pet glasses that allow the pet to see the front view of the wearing pet as if it were wearing regular eyeglasses, but can be attached with a strap or belt like goggles. Compared to goggle-type pet glasses, these pet glasses have a wider field of view and allow for lighter lens frames.

[0006] The pet glasses disclosed in Patent Document 2 include an upper bridge and a lower bridge connecting a pair of spaced-apart lens frames, fastening portions provided on the outer surfaces of the pair of lens frames, a strap engagement portion extending from the fastening portion to one side and into which a strap is engaged, and a nose pad connected to the upper bridge via a groove formed in the center.

[0007] The pet glasses disclosed in Patent Document 3 have ear hooks on both the left and right temples formed in an upward curved or straight shape, and fasteners such as straps are provided in the middle and ear hooks of the temples, respectively. These pet glasses are worn on the pet by placing the lens frame of the glasses on the dog's nose, fastening one fastener under the chin, and fastening the other fastener around the back of the head. [Prior art documents] [Patent Documents]

[0008] [Patent Document 1] U.S. Patent Application Publication No. 2005 / 0151924 [Patent Document 2] Korean Registered Patent Publication No. 10-2708008 [Patent Document 3] Japanese Patent Publication No. 2002-156612 [Overview of the Initiative] [Problems that the invention aims to solve]

[0009] The pet glasses disclosed in Patent Document 2 look like regular glasses when viewed from the front of the pet wearing them, but because they lack temples (arms), they are not fashionable enough when viewed from the side of the pet wearing them. Also, the strap secures the glasses to the nose and mouth and head, making them easy to put on, but they may easily come off depending on the shape of the pet's head.

[0010] Furthermore, the pet glasses disclosed in Patent Document 3 are designed to be worn comfortably so that they do not easily shift or fall off even when dogs move around freely, and so that dogs do not dislike wearing them. However, because they use a fastener A that goes around under the chin and a fastener B that goes around the back of the head, they are not entirely satisfactory in terms of ease of wearing. In addition, the fastener A that goes around under the chin is conspicuous from the front, and is not entirely satisfactory in terms of design.

[0011] The present invention has been made in view of the above points, and its objective is to provide eyeglasses and eyeglass frames that can be attached to a dog or other object to be worn without easily shifting or falling off even when the object moves around freely, and that the object does not dislike wearing them. A further objective is to provide eyeglasses and eyeglass frames that have the same design as ordinary human eyeglasses, in which straps, belts, and other parts other than the eyeglasses themselves are not noticeable when viewed from the front and side of a dog or other object wearing the eyeglasses. A further objective is to provide an eyeglass manufacturing method that quickly measures the shape and dimensions of the object to be worn and manufactures the eyeglasses in a way that the object does not dislike wearing them. [Means for solving the problem]

[0012] To solve the above problems, the eyeglass frame according to the present invention comprises a lens frame (14, 14R, 14L) capable of holding a pair of left and right lenses (12), and a pair of temples (20, 20R, 20L) whose base ends (21) are connected via hinges (18) to each of the left and right ends (15) of the lens frame (14, 14R, 14L), and each of the pair of temples (20, 20R, 20L) has a first branch (24) and a second branch (26) that branch in two directions in the middle of the extending direction, The first branch (24) is configured to extend diagonally upward toward the ear (P2) of the object to be attached (P) when attached to the object to be attached (P), and the second branch (26) is configured to extend diagonally downward toward the ear (P2) when attached to the object to be attached (P), and the first branch (24) and the second branch (26) are characterized in that they have an attachment portion (27) for attaching a fastener (30) which is disposed behind the ear (P2) when attached to the object to be attached (P).

[0013] The eyeglass frame according to the present invention can be worn by pets such as dogs without easily shifting or falling off even when they move around freely, and without causing discomfort to the pet. Furthermore, when viewed from the front or side of the pet wearing the frame, straps, belts, and other parts besides the eyeglass frame itself are not noticeable, and the frame can have the same design and fashion appeal as regular human eyeglasses.

[0014] Furthermore, in the eyeglass frame according to the present invention, the attachment portion (27) can be provided distal to the point where the first branch portion (24) and the second branch portion (26) branch off. Also, the fastener (30) can be a string-like or strip-like body of adjustable length, and the attachment portion (27) can be a through hole through which the fastener (30) can pass, or a hook that can lock one end of the fastener (30). In addition, the pair of temples (20) can have, at least a portion, an arc-shaped side edge that is not parallel to the direction in which the temples (20) extend. By configuring it in this way, it is possible to attach the eyeglasses in a way that prevents them from easily shifting or coming off even when pets such as dogs move around freely, and in a way that pets do not dislike. Furthermore, it is possible to make the eyeglasses more aesthetically pleasing and fashionable.

[0015] Furthermore, the eyeglasses (1) according to the present invention are characterized by including the eyeglass frame and a pair of left and right lenses (12) held in the lens frames (14, 14R, 14L) provided on the eyeglass frame. By configuring in this way, it is possible to create eyeglasses for pets that perform the functions and effects of the eyeglass frame.

[0016] Furthermore, in the eyeglasses (1) according to the present invention, the lens (12) may have the function of attenuating or reflecting visible light and / or ultraviolet light. By configuring it in this way, it is possible to create sunglasses for pets that have the same effects and properties as the eyeglass frame described above.

[0017] Furthermore, in the eyeglasses according to the present invention, the wearer (P) is a canid. The effects and benefits of the eyeglass frame are suitable for eyeglasses worn by canids that go for walks outdoors with their owners, and are therefore expected to provide owners with a high level of satisfaction.

[0018] Furthermore, the method for designing eyeglasses according to the present invention for manufacturing the above-mentioned eyeglasses (1) includes a measurement step of measuring the shape and dimensions of the nose (P4) or nose and mouth area (P3) of the object to be worn (P), and a design step of determining the shape and dimensions of the eyeglass frame based on the shape and dimensions measured in the measurement step, wherein the measurement step is characterized by using a gauge (50) connected to the support (52) by a fixing means that can adjust the clamping force, such that the support cover clamps the plurality of rods (51) arranged in the width or radial direction of the rods (51) with the support (52). This configuration allows for the rapid measurement of the shape and dimensions of the nose and mouth area of ​​a pet, which is necessary for manufacturing eyeglasses, without excessively restraining the pet. In addition, it eliminates the need to prepare expensive measuring instruments for measuring the shape and dimensions of the nose and mouth area. The reference numerals in parentheses above indicate, for reference only, the corresponding reference numerals in the drawings of the embodiments described later. [Effects of the Invention]

[0019] The eyeglass frame and eyeglasses equipped with the present invention can be worn by pets such as dogs without easily shifting or falling off even when they move around freely, and without causing discomfort to the pet. Furthermore, when viewed from the front and side of the pet wearing the eyeglasses, straps, belts, and other parts besides the eyeglasses themselves are not noticeable, and the design and fashionability are the same as ordinary human eyeglasses. In addition, the eyeglass design method according to the present invention for manufacturing the eyeglasses allows for the rapid measurement of the shape and dimensions of the pet's nose and mouth, etc., which are necessary for manufacturing the eyeglasses, without excessively restraining the pet.

Mode for Carrying Out the Invention

[0021] Hereinafter, referring to the accompanying drawings, a pair of glasses (pet glasses) for a pet having ears such as a dog, which is an embodiment of the present invention, will be described.

[0022] In the following description, in the glasses 1, the front-back, up-down, and left-right directions follow the front-back, up-down, and left-right directions of the head of the pet P on which the glasses 1 are worn. For example, in the pair of lenses 12 provided in the glasses body 10, the one corresponding to the right eye of the pet P is on the right side (which is the left side in the front view), and the one corresponding to the left eye is on the left side (which is the right side in the front view). Also, in the lens frame 14 for holding the pair of lenses 12, the side closer to the eye P1 of the pet P is referred to as the rear surface or the back surface, and the side farther away is referred to as the front surface or the front. Further, in the lens frame 14, the part closer to the mouth P5 of the pet P is referred to as the lower part, and the part farther away is referred to as the upper part.

[0023] Figure 1 is a front view perspective of eyeglasses 1 according to one embodiment of the present invention. Figure 2 is a front view perspective of the main body (eyeglass body 10) of eyeglasses 1, and Figure 3 is a front view perspective of the eyeglass body 10. Figures 4 and 5 are a front view and a side view of the eyeglass body 10 with the temples 20 fully extended, respectively. Figures 6 and 7 are a front view and a side view of a dog (pet) P wearing eyeglasses 1, respectively. The dashed line in Figure 6 indicates the position of the pet P's eye P1.

[0024] As shown in these figures, the eyeglasses 1 are suitably configured as eyeglasses, particularly sunglasses, to be worn on pets with ears, such as dogs. The eyeglasses 1 comprises an eyeglasses body 10 and a belt 30 as a fastener for attaching the eyeglasses body 10 to the pet P.

[0025] [Eyeglasses body] The eyeglass frame 10 comprises at least a pair of left and right lenses 12, a lens frame 14 that holds the pair of left and right lenses, and left and right temples 20 (left temple 20L, right temple 20R) connected to the left and right ends 15 of the lens frame 14 via left and right hinges 18. The part of the eyeglass frame 10 excluding the lenses 12 is the eyeglass frame.

[0026] <vine> The temples are the most distinctive part of the eyeglasses of the present invention, and are significantly different from ordinary eyeglasses for humans, and from ordinary eyeglasses for pets that resemble ordinary eyeglasses for humans but are designed solely for fashion purposes. In other words, the temples of the eyeglasses of the present invention are designed to be suitable for pets, such as dogs, so that they do not easily slip or fall off even when the pet moves around freely, and so that the pet does not dislike wearing them. Furthermore, the temples 20 of the eyeglasses 1 in this embodiment are designed so that the belt 30 as a fastener is not conspicuous when viewed from the front or side of the pet P, and have the same design and fashionability as ordinary eyeglasses for humans.

[0027] The left and right temples 20 branch out in two directions midway along their extension direction. That is, the left and right temples 20 are composed of a main stem 22 extending from the base end 21 of the temple 20, and a first branch and a second branch branching off from the main stem 22. The first branch 24 extends diagonally upward and backward relative to the extension direction of the main stem 22. On the other hand, the second branch 26 extends diagonally downward and backward relative to the extension direction of the main stem 22. When the glasses 1 are fitted to pet P, the first branch 24 extends diagonally upward toward pet P's ear P2, and the second branch 26 extends diagonally downward toward pet P's ear P2.

[0028] When the extension direction of the main stem 22 is taken as the reference direction (0° direction), the first branch portion 24 extends in the +60° direction, and the second branch portion 26 extends in the -60° direction. That is, the main stem 22, the first branch portion 24, and the second branch portion 26 form a shape resembling a sideways "Y". The extension direction of the first branch portion 24 is not limited to +60°, but can be selected within the range of +30° to +85°, and is preferably selected within the range of +45° to +75°. On the other hand, the extension direction of the second branch portion 26 is not limited to -60°, but can be selected within the range of -30° to -85°, and is preferably selected within the range of -45° to -75°.

[0029] The first branch portion 24 and the second branch portion 26 are positioned in front of the ears of the pet P when the glasses 1 are attached to the pet P. Therefore, configuring the first branch portion 24 and the second branch portion 26 to extend along the contour of the front of the ears of the pet P is preferable for fastening them to the pet P with the belt 30. Furthermore, this configuration is preferable in terms of design and fashionability, considering the appearance of the pet P wearing the glasses 1 when viewed from the side.

[0030] A longer main stem 22 results in an appearance closer to that of regular human eyeglasses, making it a suitable design for pet owners who want their pets to wear regular human eyeglasses 1. However, reducing the absolute value of the angle in the extension direction of the first branch 24 and the second branch 26 causes the point where the first branch 24 and the second branch 26 branch off from the main stem 22 to move forward, thus shortening the main stem 22.

[0031] In eyeglasses 1, the main stem 22, the first branch portion 24, and a portion of the second branch portion 26 have arc-shaped side edges that are not parallel to the direction of extension, taking into consideration the contour of the corresponding area on the pet P to which they are worn, as well as design and fashionability (see Figures 5 and 7). This configuration improves the fit of the temples 20 to the pet P and also enhances the fashionability. However, the side edges of the main stem 22, the first branch portion 24, and the second branch portion 26 may be formed parallel to the direction of extension of the first branch portion 24 and the second branch portion 26, that is, in a straight line rather than an arc.

[0032] The first branch 24 and the second branch 26 are provided with through holes 27 at their distal ends (the most distal end or near the distal end) from the branching point, which serve as attachment points for the belt 30. The through holes 27 of the first branch 24 and the second branch 26 are flattened to accommodate the attachment of the flattened belt 30. Furthermore, the shape of the flattened through holes 27 is such that the shorter side substantially coincides with the extending direction of the first branch 24 and the second branch 26. By making the through holes 27 this shape, the belt 30 can be easily attached to surround the left and right ears of the pet P.

[0033] The shape of the through-hole 27 is not limited to a flattened shape, but it is preferable that it be shaped according to the cross-section of the string-like or strip-like material used as a fastener. Furthermore, the mounting portion is not limited to a through-hole, and may be a hook or the like capable of locking the fastener. In addition, the fastener may be provided with a locking mechanism, and a corresponding locking mechanism may be provided on the mounting portion.

[0034] The left and right temples 20 are connected at their base ends 21 to the left and right ends 15 of the lens frame 14 via hinges 18. The base ends 21 are screwed to a pivot member 18c that rotates around a shaft member 18a at the hinge 18. Therefore, the left and right temples 20 can be closed by rotating the right temple 20R to the right and the left temple 20L to the left around the shaft member 18a of the hinge 18. Conversely, the left and right temples 20 can be opened by rotating the right temple 20R to the left and the left temple 20L to the right around the shaft member 18a.

[0035] <Composition of the eyeglass frame excluding the temples> The left and right lenses 12 have the function of attenuating or reflecting visible light and / or ultraviolet light. With this configuration, the eyeglasses 1 function as sunglasses. The left and right lenses 12 can be fitted with known techniques used in sunglasses for humans to attenuate or reflect visible light and / or ultraviolet light.

[0036] The left and right lenses 12 may be so-called prescription lenses, having the function of adjusting the vision of pet P, in addition to the function of attenuating or reflecting visible light and / or ultraviolet light, or in lieu thereof. With this configuration, the eyeglasses 1 can be used to treat vision-related diseases in pet P and / or to compensate for vision loss caused by such diseases. Known techniques used in human eyeglasses can be applied to the left and right lenses 12 to add the function of adjusting vision.

[0037] The lens frame 14 comprises a left lens frame 14L, a right lens frame 14R, a bridge 16 connecting the left lens frame 14L and the right lens frame 14R, and a pair of nose pads 17 that contact the nose and mouth area P3 or nose P4 of the pet P when the glasses are fitted to the pet. The nose pads 17 in the glasses 1 are integrally formed with the lens frame 14.

[0038] The bridge 16 is located approximately in the center of the lens frame 14. In eyeglasses 1, the bridge 16 is integrally formed with the left lens frame 14L and the right lens frame 14R.

[0039] The bridge 16 may be made from the same or different material as the left lens frame 14L and the right lens frame 14R, and then connected to the left lens frame 14L and the right lens frame 14R by screwing, welding, or other means. As with ordinary eyeglasses, metal materials may also be used as the same or different material.

[0040] Furthermore, the bridge 16 may be made of a plastic or elastic material. This allows for adjustment of the fitting state by observing how it looks when attached to a pet. If the bridge 16 is made of an elastic material, the curvature of the bridge can be adjusted by adjusting the belt 30, which will be described later as a fastener.

[0041] The nose pad 17 is provided in the left lens frame 14L and the right lens frame 14R at a position below or adjacent to the bridge 16. In this embodiment, the nose pad 17 is integrally formed with the left lens frame 14L and the right lens frame 14R.

[0042] The nose pads 17 may be made from the same or different materials as the left lens frame 14L and the right lens frame 14R, and then connected to the left lens frame 14L and the right lens frame 14R by screwing, welding, or other means. As with ordinary eyeglasses, metal materials may also be used as the same or different materials, in addition to resin materials.

[0043] The hinge 18 connects the end 15 of the lens frame 14 to the temple 20. The hinge 18 has a shaft member 18a, a support member 18b fixed to the end 15 of the lens frame 14 and supporting the shaft member 18a, and a rotating member 18c fixed to the base end 21 of the temple 20 and rotating around the shaft member 18a. By rotating the rotating member 18c of the hinge 18, the temple 20 can be rotated between an open state for attaching the glasses 1 to the pet P and a folded closed state.

[0044] The rotating member 18c is supported by the support member 18b so that it can rotate around the shaft member 18a, by screwing together the shaft member 18a, which is configured as a male thread, and the support member 18b which is configured as a female thread.

[0045] The hinge 18 is made of metal, just like that of ordinary eyeglasses for humans. The support member 18b is screwed to the end 15 of the lens frame 14, which is made of resin.

[0046] 〔belt〕 The eyeglasses 1 are equipped with two belts 30 as fasteners for attaching the eyeglasses body 10 to the pet P. Each belt 30 includes a buckle 34 having a female part and a male part that can be attached to the female part, a strip-shaped belt body 32 that can be separated by the buckle 34, and two adjusters 36 provided near both ends of the belt body 32.

[0047] By inserting one end of the belt body 32, through which the adjuster 36 is inserted, into a through hole 27 provided in the first branch 24 or second branch 26 of the stalk 20, and then inserting it back into the adjuster 36, one end of the belt body 32 becomes a ring shape through which the through hole 27 is inserted and connected to the through hole 27. The other end of the belt body 32 is connected to another through hole 27 in the same manner. The length of the belt body 32 is then adjusted by the adjuster 36.

[0048] In the example shown in Figure 1, one belt 30 has one end of the belt body 32 connected to a through hole 27 in the first branch 24 of the right temple 20R, and the other end connected to a through hole 27 in the second branch 26 of the left temple 20L. The other belt 30 has one end of the belt body 32 connected to a through hole 27 in the second branch 26 of the right temple 20R, and the other end connected to a through hole 27 in the first branch 24 of the left temple 20L. As a result, when the glasses 1 are attached to pet P, the two belts 30 are crossed over the back of pet P's head.

[0049] Figures 6 and 7 are front and side views of a dog wearing glasses 1. In dogs with long fur, the two belts 30 can be covered with fur to conceal them from view. By making only the glasses body 10 visible, the glasses can be securely attached so that they do not easily shift or fall off even when the dog moves around freely, while appearing to be regular glasses from both the front and the side.

[0050] Alternatively, one belt 30 can be connected to the right temple 20R by connecting both ends to through holes 27 provided in the first branch 24 and second branch 26 of the right temple 20R, and the other belt can be connected to the left temple 20L by connecting both ends to through holes 27 provided in the first branch 24 and second branch 26 of the left temple 20L. In this case, when the glasses 1 are attached to the pet P, the two belts 30 are each fastened to separate ears P2 of the pet P.

[0051] Belt 30 is an example of a belt suitable for eyeglasses 1. Eyeglasses 1 can also be fitted with other known belts whose length can be freely adjusted, not just belt 30. Furthermore, eyeglasses 1 can also be fitted with a belt that is pre-formed to a length appropriate to the shape of the head of the pet P to be fitted, and is stretchable due to rubber elasticity or the like.

[0052] [Method of manufacturing eyeglasses] The eyeglass frame can be manufactured using known techniques for producing ordinary eyeglasses for humans. Since the manufacturing method is selected based on the materials of each part, a detailed explanation will be omitted, and instead, the design method for the eyeglass frame, which is performed prior to manufacturing, will be described.

[0053] For pet glasses, the optimal width of the lens frame, the width of the bridge, and the length of the temples vary considerably not only depending on the type of pet, but also on the breed (in the case of dogs). Therefore, measuring the shape and dimensions of the parts of the pet to which the glasses will be worn is important in order to create glasses that can be worn without easily shifting or falling off even when the pet moves around freely, and that the pet does not dislike wearing.

[0054] When designing eyeglasses, the first step is to measure the shape and dimensions of the corresponding parts of the eyeglass frame in order to determine the shape and dimensions of each part.

[0055] The overall shape and dimensions of the head and ear contours can be inferred from the photographs taken. However, the boundaries of the nose and mouth are not clearly defined, and it is necessary to measure the width of the bridge and the position of the nose pads to determine them. Furthermore, the measurements must be taken quickly without excessively restraining the pet. Needless to say, it is desirable that the measuring equipment is not expensive.

[0056] Based on these requirements, a gauge 50 is used as a measuring instrument. The gauge 50 comprises a plurality of rods 51, a support 52, and a support cover (not shown). The support cover is fixed to the support 52 by a fixing means (not shown) with adjustable clamping force, such as a screw, so as to clamp the plurality of rods 51 which are arranged in the width or radial direction of the rods 51. When the clamping force of the fixing means is weakened (the screw is loosened), the plurality of rods 51 can each slide independently in the longitudinal direction. On the other hand, when the clamping force of the fixing means is strengthened (the screw is tightened), the sliding state of each of the plurality of rods 51 can be fixed.

[0057] As shown in Figure 8, the clamping force of the fixing means is weakened, and the gauge 50, with its multiple rods 51 now slidable, is brought into contact with the area to be measured, such as the nose and mouth P3 of the pet P. Then, the state in which the multiple rods 51 have slid (the state in which the area to be measured has been molded) is fixed in place by the fixing means. The shape and dimensions of the area to be measured are determined based on the mold fixed to the gauge 50. The shape and dimensions of the area to be measured can also be determined by tracing the mold fixed to the gauge 50 onto paper or by acquiring it as an image.

[0058] In addition to measurements using Gauge 50, measurements based on images taken of the pet P's head can also be used. Furthermore, data on the shape and dimensions of measurement targets for each type of pet P can be created in a database, and this database data can be used. In this case, the data for areas not measured with the gauge may be corrected based on the relationship between the measured values ​​of the areas measured with the gauge and the data in the database. This reduces the number of measurement targets that need to be measured.

[0059] Alternatively, the shape and dimensions of the pet P measured to manufacture the eyeglass frame 10 may be stored in a database and reused when manufacturing the eyeglass frame 10 again, or registered in the database as data relating to pet P of the same variety.

[0060] Next, based on the shape and dimensions of the measurement target, the shape and dimensions of each part of the eyeglass frame are determined. Specifically, the width of the lens frame, the width of the bridge, and the length of the temples are determined. In addition, the degree of curvature of the bridge in the front-to-back direction, and the shape and dimensions of each part of the temples are determined.

[0061] For the vine 20, for example, the length of the trunk 22, the degree of bending in the direction of extension, and the shape of the side edges, as well as the length of the first branch 24 and the second branch 26, the direction of extension, the degree of bending in the direction of extension, the shape of the side edges, and the position and shape of the through holes 27 are determined.

[0062] By using the gauge 50, the shape and dimensions of the nose and mouth area P3 of the pet P can be quickly measured without excessively restraining the pet P. Furthermore, it eliminates the need to prepare expensive measuring instruments for measuring the shape and dimensions of the nose and mouth area P3.

[0063] [Variation] The temples and bridge may have an extendable structure in at least a portion of them, allowing their length to be adjusted. Alternatively, the temples and bridge may have a bendable structure in at least a portion of them, or be made of a bendable material, allowing the degree of bending to be adjusted. By configuring them in this way, after the eyeglasses are manufactured, the shape and dimensions of the eyeglasses can be adjusted according to how well they fit the pet or according to the pet's growth.
