REFERENCE TO PENDING PRIOR PATENT APPLICATION 
       [0001]    This application claims the benefit under 35 U.S.C. 119 (e) of U.S. Provisional Patent Application No. 61/157,432, filed Mar. 4, 2009 by Robert Hall for “EYEGLASSES WITH SEPARABLE EYECUP ASSEMBLY AND EYEGLASSES FRAME,” which patent application is hereby incorporated herein by reference. 
     
    
     FIELD 
       [0002]    This disclosure pertains to eyewear. More particularly, this disclosure pertains to eyewear, including glasses and sunglasses, having an eyecup and methods of use and doing business. 
       BACKGROUND 
       [0003]    Eyeglasses and other eyewear has been used for treatment of dry eyes and other eye related afflictions. Typically, one or more sealing members are positioned between the eyewear and the user&#39;s face. These sealing members are typically configured to make a good seal with the user&#39;s face, but are also readily visible to others. These types of notorious displays of the sealing members renders the eyewear different than other user&#39;s eyewear. For children and other users, this may be a significant issue. Some users may opt not to wear eyewear with sealing members to avoid looking different than their peers. Others may not choose to purchase eyewear with readily visible sealing members. 
         [0004]    Dry eye conditions affect many people in various life stages. In particular, more women than men tend to have issues with dry eyes and may use eye drops for treatment. Such eye drops tend to be relatively expensive and disruptive to reapply at numerous times in a day. Eyewear to retain moisture with or without the application of medicinal eye drops has been used by some people with dry eyes. However, many women and men are not comfortable wearing bulky and unfashionable eyewear. Furthermore, the eyewear may become dirty or degraded over time due to contact with oils or makeup from a user&#39;s face. Due to these types of issues, users may not benefit from currently available eyewear. 
         [0005]    In addition, wearing of eyeglasses and other eyewear while engaged in social activities, professional activities in an office environment, and other work tasks can be difficult for various reasons. One key reason is a fundamental inability of most eyeglass frames to appear aesthetically pleasing and also provide a protective seal around a wearer&#39;s eyes for preventing wind, dust, dirt, moisture, glare, ultraviolet radiation, and other contaminants and debris from contacting, and potentially damaging, the wearer&#39;s eyes. 
         [0006]    Many people wear eyeglasses for reasons other than, or in addition to, vision correction. Well-known examples are the large number of different types of “sunglasses” that reduce the intensity (and/or change the wavelength) of light reaching the wearer&#39;s eyes. Other well-known examples are so-called “safety glasses” usually used for eye protection in industrial and laboratory environments. Yet other well-known examples are various “goggles” and the like. 
         [0007]    As used herein, “eyewear” generally encompasses all of various eyeglass types summarized above as well as any other analogous device configured to fit to a person&#39;s face and that includes a “frame” and “lenses.” The frame typically has a front portion situated largely in front of the wearer&#39;s eyes. The lenses are mounted to the front portion and transmit at least some light to the wearer&#39;s eyes. Mounted to the front portion are “temple pieces” that extend rearward from the front portion to engage and/or rest upon the wearer&#39;s ears. The temple pieces usually, but not necessarily, are hinged to the front portion. 
         [0008]    To address the concerns raised by the need for protection of the wearer&#39;s eyes during activity, various schemes have been adopted. For example, certain types of eyewear, notably safety goggles and certain types of eyeglasses, employ shields, liners, and other sealing members for protecting a wearer&#39;s eyes during use. Unfortunately, the sealing members of these types of eyewear are generally readily apparent and unsightly for many uses. Therefore, such eyewear may fail to provide overall pleasing comfort and adequate therapeutic effect for the wearer&#39;s eyes during activity, while also being able to provide sufficient venting, or retain the versatility from which, for example, extended wear may benefit. 
         [0009]    Some schemes have been tried to improve the protection of a wearer&#39;s eyes by providing various types of sealing members. For example, one scheme involves adjusting the spacing between two lenses or pivoting eye cups to conform to the facial contour of a wearer. Another scheme involves inflating or deflating an inflatable cushion member to provide an adjustable seal against contaminants. A third scheme involves retracting or extending, such as by pivoting, retractable eyeshields to provide eye protection that can be adjusted to an individual wearer. Unfortunately, these various schemes tend to be highly specialized, have very noticeable sealing members, and do not address all needs, especially needs posed by concepts of style and utility that arise with modern eyeglasses. 
         [0010]    Typically, eyeglasses and eyecup assemblies have been retailed as a unit without the ability to select separate components that may provide a better fit to a user. The fitter, eye care provider, or other retailer may be precluded from obtaining additional sales due to the lack of selection from separate components. Devices in the prior type have typically provided one set of eyecups per set of eyeglasses. Adapting to various faces and head shapes has thus long presented a serious problem. 
         [0011]    Flexibility of eyecups has been implemented to some degree, such as with foam liners. But this can be uncomfortable for certain users and not provide any sealing at all for others. 
         [0012]    Eyecup assemblies may wear out or otherwise become less desirable. When this happens, a user may be less apt to use the eyecup assembly. In addition, the expense of purchasing multiple eyecups at one time, traveling to a retail location to purchase new eyecups, or placing separate orders for eyecups may be inconvenient for a user. A more convenient system may be very beneficial to eyecup users.

     DETAILED DESCRIPTION 
       [0050]    This disclosure is set forth in the context of representative embodiments that are not intended to be limiting in any way. 
         [0051]    Referring to  FIGS. 1A ,  1 B,  2 ,  2 A,  2 B and  2 C, and in an embodiment, there is provided an eyecup assembly  10  with seal material  12  extending from eyecup frame  14 . Seal material  12  generally extends away from eyecup frame  14  toward the face of a user. Seal material  12  may be provided in a substantially continuous extension from eyecup frame  14 . This substantially continuous extension may form a sealed space therein when seal material  12  abuts the face of a user. Eyecup assembly  10  may be formed as a single portion (i.e., both lenses are contained in a single eyecup assembly structure) with seal material  12  disposed for engagement with portions of the face adjacent to both the left and right eyes of a user. Eyecup frame  14  may be formed out of a single material or multiple materials. Eyecup frame  14  could also include other removable eyeglass components, such as eyeglass side arms, to accommodate differing head shapes and sizes. For example, one set of side arms might be a given length and others might be ¼ or ½ inches longer, in increments from which the fitter or user might select in order to adapt the eyeglasses to the user&#39;s unique distance between the nose bridge and ears. Seal material  12  may be formed from the same material or a different material forming eyecup frame  14 . For example, seal material  12  may be formed from silicone, plastic, or a combination of both. 
         [0052]    In one embodiment, seal material  12  may extend away from eyecup frame  14  (toward the face of a user) and have a thinner transverse cross-section than a transverse cross-section of eyecup frame  14 . In an embodiment, seal material  12  and eyecup frame  14  may be formed of co-molded plastic and silicone. A less dense portion of the co-molded plastic and silicone may be positioned toward the face of the user. 
         [0053]    One or more vents  16  may be positioned through eyecup frame  14 . In an embodiment, vents  16  may be positioned through eyecup frame  14  on an eyeglasses engaging portion  21  ( FIG. 2 ). Vents  16  may extend from a portion of eyecup frame  14  outside of a sealed chamber ultimately formed within seal material  12  when disposed on the user&#39;s face to a portion of eyecup frame inside of the sealed chamber. In an embodiment, vents  16  may be disposed through opposed top and bottom portions of eyecup frame  14  as well as through right side and left side portions of the eyecup frame  14  corresponding to each one of the user&#39;s eyes. Vents  16  in eyecup assembly  10  may be configured to control airflow to the user&#39;s eyes. Vents  16  may be channels or notches passing in a relatively straight trajectory through seal material  12 . In other embodiments, vents  16  may include at least one angular bend to adjust airflow. Vents  16  may include one or more bifurcations to allow airflow, provide a select amount of resistance, and inhibit entry of unwanted matter. Vents  16  may be permanently disposed in an open position. In another embodiment, plugs may be provided for selectively closing vents  16 . For example, plugs may include a mechanical assembly to open and close vents  16 . In one embodiment, vents may be provided in a frame portion of the eyeglasses. 
         [0054]    Attachment portions  18 , which may be formed for a metal material  18 , another magnetically attracting material  18 , or magnets  18 , may be provided in eyecup frame  14 . Generally, attachment portions  18  are formed in both the upper and lower sections of the eyecup frame  14  on the side opposite to seal material  12 . Attachment portions  18  may be disposed in a direction in opposition to seal material  12  in order to facilitate attachment with a set of eyeglasses. In other embodiments, attachment portions may be disposed in other orientations to facilitate attachment with a set of glasses. Attachment portions  18  may be elongated or spherical and may correspond in a substantially congruent manner to other features disposed on a set of eyeglasses. Attachment portions  18  may be disposed on opposed top and bottom portions of eyecup frame  14  as well as on right side and left side portions of eyecup frame  14  corresponding to each one of the user&#39;s eyes. This disposition of attachment portions  18  provides four points relatively dispersed from one another in order to allow a secure fit between eyecup frame  14  and a pair of eyeglasses. In addition, one or more tabs  20  may extend outwardly away from one another from the outside edges of frame  14  (near the temple region when worn by a user.) Tabs  20  may have a relatively squared off profile corresponding to a slot or other recess. Tabs  20  may be configured to secure eyecup assembly  10  to a pair of eyeglasses  22  ( FIG. 3A .) 
         [0055]    Eyecup assembly  10  has seal material  12  which may extend in a relatively low profile manner toward the face of a user. In an embodiment, this low profile manner relates to the cross-sectional width of seal material  12  when viewed from a direction orthogonal to a user&#39;s field of vision through the eyecup assembly. In various embodiments, seal material  12  may be transparent, clear, or otherwise blend into the eyeglasses so as to conceal its view when worn by the user. Exemplary views of seal material  12  are shown, for example, in  FIG. 1A  with the seal material extending upwardly away from the eyecup assembly and in  FIG. 1B  with the seal material extending downwardly away from the eyecup assembly. 
         [0056]    As described above, seal material  12  may be configured such that it cannot be readily seen by others. Others looking at the user wearing eyecup  10  may only see eyecup frame  14 , but not seal material  12 , when looking at a direct view of the eyeglasses. For example, a direct view of an eyeglasses engaging portion  21  ( FIG. 2 ) may hide seal material  12  behind eyeglasses engaging portion  21  due to the thin configuration of seal material  12 . It should be appreciated that eyecup assembly  10  may be configured without any lenses disposed within the perimeter formed by seal material  12 . However, in an alternative embodiment, eyecup assembly  10  may be provided with one or more lenses within the perimeter formed by seal material  12 . These lenses in eyecup assembly may be separate from eyeglasses frame  24  ( FIG. 3A .) 
         [0057]    As discussed above, eyecup frame  14  may be provided with vent  16  and metal attachment portion  18 . An exemplary view of vent  16  and metal attachment portion  18  are illustrated in an enlarged portion in  FIGS. 2A and 2B . A tab  20  may extend from eyecup frame  14 . For example, an enlarged view of tab  20  is shown in  FIG. 2C  Attachment portion  18  and tab  20  may be used either alone or in conjunction with one another to secure eyecup frame  14  to eyeglasses frame  24  ( FIG. 3A .). 
         [0058]    In an embodiment, eyeglasses  22  may include an eyeglass frame  24 . The eyeglass frame  24  may be a sunglass frame in particular in some embodiments. One or more magnets  26 , or other attachment devices, such as a metal material or another magnetically attracting material, may be provided for attachment of eyeglass frame  24  with metal material  18  attached to eyecup frame  14 . Magnets  26  may be positioned on one or both of eyecup frame  14  and eyeglasses frame  24 . Magnets or other attachment devices  26  may be disposed through opposed top and bottom portions of eyeglasses frame  24  as well as through right side and left side portions of the eyecup frame  14  corresponding to each one of the user&#39;s eyes. Magnets or other attachment devices  26  may be disposed in a direction toward a user&#39;s face when disposed on the user. This disposition of magnets or other attachment devices  26  provides four points relatively dispersed from one another in order to allow a secure fit between eyecup frame  14  and eyeglass frame  24  of pair of eyeglasses  22 . For example, exemplary views of eyeglass frame  24  are shown in  FIGS. 3A and 3B . 
         [0059]    Frame  24  may form one or more slots  28  for removable attachment of one or tabs  20 . Slots  28  may be disposed toward a user&#39;s face when frame  24  is worn and may be elongated in a vertical orientation corresponding to tabs  20  of eyecup frame  14 . Attachment of tabs  20  with slots  28  removably attach eyecup frame  14  with eyeglasses frame  24  so as to attach eyecup assembly  10  with eyeglasses  22 . Eyeglasses frame  24  may form a pair of apertures  30 , which may each contain at least one lens  32 , and this lens  32  may be transparent or it may varying of translucency, coloration, or photoactivity, among many other possible characteristics for differing applications, uses, etc. In one embodiment, eyeglasses frame extends in a substantially surrounding configuration to two lenses  32 , which are each provided to correspond substantially with a user&#39;s two eyes. In an embodiment, the user may wear eyeglasses  22  either with or without eyecup assembly  10  attached in place. 
         [0060]    A partial view of eyeglasses frame  24  with magnets  26  on top and bottom portions for engagement with metal portions  18  of eyecup assembly  10  is shown in  FIG. 3C . An exemplary view of slot  28  for eyecup tab  20  is shown in  FIG. 3D . 
         [0061]    Eyeglasses  22  and eyecup assembly  10  may be selectively positioned in attachment with one another with seal material  12  substantially concealed from the view of others when worn by a user. For example, concealed nature of seal material  12  is illustrated in  FIGS. 4A-4D . Eyeglasses  22  and eyecup assembly  10  may be configured to mate with one another such that sealing material  12  provides protection to the user while eyecup frame  14  is disposed a significant distance away from the user&#39;s face. This low-profile configuration may provide comfort and usability of eyeglasses  22  with eyecup assembly  10  in use together with, or removed from, eyeglasses frame  24 . The concealed nature of seal material  12  also provides a cosmetic nature that many users prefer as others are not distracted by a set of glasses with a prominent sealing structure. 
         [0062]    Eyeglasses  22  and eyecup assembly  10  may be disengaged from one another for cleaning or selection of seal material  12 . For example, this disengagement allows replacement, repair, resizing, or refitting of the eyecup assembly  10 . In an embodiment, eyeglasses  22  may include multiple fit options by providing two or more different sized eyecup assemblies. Replacement of eyecup assembly  10  with eyeglasses  22  may be important for many reasons. One reason may include providing new eyecups in place of worn eyecups. Another reason may be to change the color, style or some other feature of the eyecups with another desired feature (e.g., change tan eyecups to see-through eyecups.) Eyecups may be provided with designs or themes, such as the replaceable “skin” of a mobile telephone. Yet another reason may be to adapt the eyecups to different conditions such as, but not limited to, dry weather or rainy weather. Eyecups may include differing types of vents in various ones of the eyecup assemblies. The many different kinds of eyecup assemblies may also provide a new business model for optometrists and others selling these types of eyeglasses  22  with eyecup assembly  10 . This recurring revenue may be from salves of eyeglasses with one or more sets of eyecups, or just from the sale of replacement, upgraded, or designer eyecups. Eyecup assembly  10  may also be designed for substitution when a user&#39;s face changes or the eyecups simply wear out. 
         [0063]    For example,  FIG. 5  illustrates eyeglasses  22  and eyecup assembly  10  in a configuration slightly apart from one another. In this position, magnets  26  and metal portions  18  generally align with one another. When not in use, the removable eyecup assembly  10  may be stored as a single piece. When additional eye protection is necessary or desirable, eyecup assembly  10  may be attached to eyeglasses  22  in a single step by placing eyecup frame  14  adjacent to eyeglasses frame  24 . Tabs  20  may be inserted into slots  28  for an additional securing of eyecup frame  14  to eyeglass frame  24 . For example, tab  20  is shown slightly removed from slot  28  in  FIG. 6 . 
         [0064]    Various exemplary illustrations of eyeglasses  22  with eyecup assembly  10  in engagement with one another are provided by  FIGS. 7-9  and  13 . Eyecup assembly  10  may be separated from eyeglasses  22  and is shown apart from eyeglasses  22  in  FIGS. 10-12 . Eyecup frame  14  may be flexible and is shown being twisted in  FIG. 10 . In various embodiments, eyecup frame  10  may be significantly more flexible than eyeglasses frame  24 . 
         [0065]    Referring to  FIGS. 14-18 , and in another exemplary embodiment, there is provided an eyecup assembly  110  with seal material  112  extending from eyecup frame  114 . Seal material  112  generally extends away from eyecup frame  114  toward the face of a user. Seal material  112  may be provided in a substantially continuous extension from eyecup frame  114 . This substantially continuous extension may form a sealed space therein when seal material  112  abuts the face of a user. Eyecup assembly  110  may be formed as a single portion (i.e., both lenses are contained in a single eyecup assembly structure) with seal material  112  disposed for engagement with portions of the face adjacent to both the left and right eyes of a user. Eyecup frame  114  may be formed out of a single material or multiple materials. Eyecup frame  114  could also include other removable eyeglass components, such as eyeglass side arms, to accommodate differing head shapes and sizes. For example, one set of side arms might be a given length and others might be ¼ or ½ inches longer, in increments from which the fitter or user might select in order to adapt the eyeglasses to the user&#39;s unique distance between the nose bridge and ears. Seal material  112  may be formed from the same material or a different material forming eyecup frame  114 . For example, seal material  112  may be formed from silicone, plastic, or a combination of both. 
         [0066]    In one embodiment, seal material  112  may extend away from eyecup frame  114  (toward the face of a user) and have a thinner transverse cross-section than a transverse cross-section of eyecup frame  114 . In an embodiment, seal material  112  and eyecup frame  114  may be formed of co-molded plastic and silicone. A less dense portion of the co-molded plastic and silicone may be positioned toward the face of the user. 
         [0067]    One or more vents  116  may be positioned through eyecup frame  114 . In an embodiment, vents  116  may be positioned through eyecup frame  114  on an eyeglasses engaging portion  121  ( FIG. 17 ). Vents  16  may extend from a portion of eyecup frame  114  outside of a sealed chamber ultimately formed within seal material  112  when disposed on the user&#39;s face to a portion of eyecup frame inside of the sealed chamber. In an embodiment, vents  116  may be disposed through opposed top and bottom portions of eyecup frame  114  as well as through right side and left side portions of the eyecup frame  114  corresponding to each one of the user&#39;s eyes. Vents  116  in eyecup assembly  110  may be configured to control airflow to the user&#39;s eyes. Vents  116  may be channels or notches passing in a relatively straight trajectory through seal material  112 . In other embodiments, vents  16  may include at least one angular bend to adjust airflow. Vents  116  may include one or more bifurcations to allow airflow, provide a select amount of resistance, and inhibit entry of unwanted matter. Vents  116  may be permanently disposed in an open position. In another embodiment, plugs may be provided for selectively closing vents  116 . For example, plugs may include a mechanical assembly to open and close vents  116 . In one embodiment, vents may be provided in a frame portion of the eyeglasses. 
         [0068]    Attachment portions  118 , which may be formed for a metal material  18 , another magnetically attracting material  118 , or magnets  118 , may be provided in eyecup frame  114 . Generally, attachment portions  18  are formed in both the upper and lower sections of the eyecup frame  114  on the side opposite to seal material  112 . Attachment portions  18  may be disposed in a direction in opposition to seal material  112  in order to facilitate attachment with a set of eyeglasses. In other embodiments, attachment portions may be disposed in other orientations to facilitate attachment with a set of glasses. Attachment portions  118  may be elongated or spherical and may correspond in a substantially congruent manner to other features disposed on a set of eyeglasses. Attachment portions  118  may be disposed on opposed top and bottom portions of eyecup frame  114  as well as on right side and left side portions of eyecup frame  114  corresponding to each one of the user&#39;s eyes. This disposition of attachment portions  118  provides four points relatively dispersed from one another in order to allow a secure fit between eyecup frame  114  and a pair of eyeglasses. 
         [0069]    Eyecup assembly  110  has seal material  112  which may extend in a relatively low profile manner toward the face of a user. In an embodiment, this low profile manner relates to the cross-sectional width of seal material  112  when viewed from a direction orthogonal to a user&#39;s field of vision through the eyecup assembly. In various embodiments, seal material  112  may be transparent, clear, or otherwise blend into the eyeglasses so as to conceal its view when worn by the user. Exemplary views of seal material  112  are shown, for example, in  FIG. 14  and with the seal material extending downwardly away from the eyecup assembly and in  FIGS. 16 and 18  with the seal material extending outwardly away from the eyecup assembly. 
         [0070]    As described above, seal material  112  may be configured such that it cannot be readily seen by others. Others looking at the user wearing eyecup  110  may only see eyecup frame  114 , but not seal material  112 , when looking at a direct view of the eyeglasses. For example, a direct view of an eyeglasses engaging portion  121  ( FIG. 17 ) may hide seal material  112  behind eyeglasses engaging portion  121  due to the thin configuration of seal material  112 . It should be appreciated that eyecup assembly  110  may be configured without any lenses disposed within the perimeter, formed by seal material  112 . However, in an alternative embodiment, eyecup assembly  110  may be provided with one or more lenses within the perimeter formed by seal material  112 . These lenses in eyecup assembly may be separate from eyeglasses frame  124  ( FIGS. 14-17 .) 
         [0071]    Referring to  FIG. 18 , seal material  112  may extend at differing distances from eyecup frame  114 . In one embodiment, eyecup frame  114  may have a thickness of about 2 mm from the side of eyeglasses engaging portion  121  ( FIG. 17 ) to the side of seal material  112 . Including the about 2 mm thickness of eyecup frame  114 , seal material  112  may extend varying distances and, for example, may extend about 24 mm at  134 A, about 18 mm at  134 B, about 17 mm at  134 C, about 6 mm at  134 D, and about 10 mm at  134 E. 
         [0072]    In an embodiment, eyeglasses  122  may include an eyeglass frame  124 . One or more magnets  126 , or other attachment devices, such as a metal material or another magnetically attracting material, may be provided for attachment of eyeglass frame  124  with metal material  118  attached to eyecup frame  114 . Magnets  126  may be positioned on one or both of eyecup frame  114  and eyeglasses frame  124 . Magnets or other attachment devices  126  may be disposed through opposed top and bottom portions of eyeglasses frame  124  as well as through right side and left side portions of the eyecup frame  114  corresponding to each one of the user&#39;s eyes. Magnets or other attachment devices  126  may be disposed in a direction toward a user&#39;s face when disposed on the user. This disposition of magnets or other attachment devices  126  provides four points relatively dispersed from one another in order to allow a secure fit between eyecup frame  114  and eyeglass frame  124  of pair of eyeglasses  122 . For example, exemplary views of eyeglass frame  124  are shown in  FIG. 17 . 
         [0073]    Eyeglasses frame  124  may form a pair of apertures  130 , which may each contain at least one lens  132 . In one embodiment, eyeglasses frame extends in a substantially surrounding configuration to two lenses  132 , which are each provided to correspond substantially with a user&#39;s two eyes. In an embodiment, the user may wear eyeglasses  122  either with or without eyecup assembly  110  attached in place. 
         [0074]    Eyeglasses frame  124  with magnets  126  on top and bottom portions for engagement with metal portions  118  of eyecup assembly  110  is shown in  FIG. 17 . 
         [0075]    Eyeglasses  122  and eyecup assembly  110  may be selectively positioned in attachment with one another with seal material  12  substantially concealed from the view of others when worn by a user. For example, concealed nature of seal material  112  is illustrated in  FIG. 16 . Eyeglasses  122  and eyecup assembly  110  may be configured to mate with one another such that sealing material  12  provides protection to the user while eyecup frame  114  is disposed a significant distance away from the user&#39;s face. This low-profile configuration may provide comfort and usability of eyeglasses  122  with eyecup assembly  110  in use together with, or removed from, eyeglasses frame  124 . The concealed nature of seal material  112  also provides a cosmetic nature that many users prefer as others are not distracted by a set of glasses with a prominent sealing structure. 
         [0076]    Eyeglasses  122  and eyecup assembly  110  may be disengaged from one another for cleaning or selection of seal material  112 . For example, this disengagement allows replacement, repair, resizing, or refitting of the eyecup assembly  110 . In an embodiment, eyeglasses  122  may include multiple fit options by providing two or more different sized eyecup assemblies. Replacement of eyecup assembly  110  with eyeglasses  122  may be important for many reasons. One reason may include providing new eyecups in place of worn eyecups. Another reason may be to change the color, style or some other feature of the eyecups with another desired feature (e.g., change tan eyecups to see-through eyecups.) Eyecups may be provided with designs or themes, such as the replaceable “skin” of a mobile telephone. Yet another reason may be to adapt the eyecups to different conditions such as, but not limited to, dry weather or rainy weather. Eyecups may include differing types of vents in various ones of the eyecup assemblies. The many different kinds of eyecup assemblies may also provide a new business model for optometrists and others selling or otherwise distributing or using these types of eyeglasses  122  with eyecup assembly  110 . This recurring revenue may be from salves of eyeglasses with one or more sets of eyecups, or just from the sale of replacement, upgraded, or designer eyecups. Eyecup assembly  110  may also be designed for substitution when a user&#39;s face changes or the eyecups simply wear out. 
         [0077]    For example,  FIG. 17  illustrates eyeglasses  122  and eyecup assembly  110  in a configuration partially apart from one another. In this position, magnets  126  and metal portions  118  generally align with one another. When not in use, the removable eyecup assembly  110  may be stored as a single piece. When additional eye protection is necessary or desirable, eyecup assembly  110  may be attached to eyeglasses  122  in a single step by placing eyecup frame  114  adjacent to eyeglasses frame  124 . 
         [0078]    There may be provided various methods of providing a controlled ocular environment with a pair of eyeglasses having a substantially traditional appearance. In an embodiment, the method may include selecting an eyecup assembly with a seal material extending from an eyecup frame of the pair of glasses. The eyecup assembly may be selected to form a seal with at least a portion of the face of a user. In addition, the method may include selecting an eyeglasses frame together with the eyecup assembly to substantially conceal the seal material from view of others when worn by the user. The selected eyeglasses frame and the selected eyecup assembly may together provide the substantially traditional appearance on the face of the user. 
         [0079]    In an embodiment, a method of automatically replacing eyecup assemblies is provided in which an eye care provider (ECP) or other retailer (such as an optometrist or other fitting professional) enrolls a purchaser of an initial eyecup assembly into a program with replacement eyecup assemblies delivered to the purchaser at a regular interval. For example, this regular interval may include one or more replacement eyecup assemblies being sent at a one, two, three, or six month interval. In addition, the distributor or manufacturer receives the enrollment information from the ECP and handles delivery of the replacement eyecup assemblies direct to the purchaser. This fulfillment process may be handled using a computer system to manage and track the timely delivery to the purchaser and also to handle the billing and collection of the associated charges with the customer. 
         [0080]    Another advantage of this method includes the ability to share revenue between the distributor and the ECP. An incentive to the ECP to enroll the purchaser in this automatic replacement program is a cash credit or other payment made by the distributor of the eyecups to the ECP based on the additional eyecups sold directly to the purchaser. This revenue sharing program may be based on sales directly from enrollment with the ECP at the initial purchase. In addition, this revenue sharing program may be based on sales occurring subsequent to the initial purchase. For example, the ECP may direct the purchaser to enroll online through the Internet, through a telephone number, or by other methods. It should be appreciated that the revenue share provided to the ECP on a regular basis is a new marketing tool to stimulate initial sales and reoccurring sales of replacement eyecup assemblies. 
         [0081]    Still another advantage of this method includes automatic replenishment and delivery of one or more eyecup assemblies to the purchaser and user of the eyecup and eyeglasses frame product. As one eyecup assembly begins to wear out or become less desirable to wear on a daily basis, the user will be provided with one or more additional eyecup assemblies as a replacement option. This automatic replenishment and replacement scenario may be similar to replacement of razorblades, toothbrushes, or other personal hygienic equipment that have a limited lifespan. This automatic replenishment method may ensure that a user with expensive eyeglasses will not stop using the eyecup assembly with the frames or quit using the eyeglasses entirely due to discomfort or less desirability of the eyecup assemblies with respect to aesthetic or hygienic issues. 
         [0082]    In an embodiment, a method of retailing eyeglasses may include providing an ECP or other retailer or other distributor (such as an optometrist or other fitting professional) with a plurality of eyecup assemblies. At least one of the plurality of eyecup assemblies should differ from another one of the eyecup assemblies. In one embodiment, the eyecup assemblies have a seal material extending from an eyecup frame and are sized for engagement with facial portions surrounding both left and right eyes of a user. The eyecup assemblies have one or more attachment portions may be provided in attachment to the eyecup frame. In addition, the ECP may be provided with an eyeglasses frame defining a pair of apertures. At least one lens may be disposed in each of the pair of apertures. One or more attachment devices may be provided in attachment to the eyeglasses frame. Generally, the one or more attachment devices of the eyeglasses frame and the one or more attachment portions of each of the eyecup assemblies are configured for selective attachment with one another. This allows removable attachment of a selected one of the eyecup assemblies and the eyeglasses frame with one another. 
         [0083]    The seal material of the plurality of eyecup assemblies may differ between the various eyecup assemblies. Differences may include, but are not limited to, differences in color, material, skin pattern (similar to a cell phone ornamental skin), or size. 
         [0084]    In another embodiment, a method of retailing eyeglasses may include providing an ECP or other retailer or distributor (such as an optometrist or other fitting professional) with a plurality of eyecup assemblies, but not a particular eyeglasses frame, and one or more of the eyecup assemblies differ others of the eyecup assemblies. The one or more attachment portions of the eyecup assemblies are configured for selective attachment with one or more attachment devices of an eyeglasses frame provided separately from the eyecup assemblies. This allows removable attachment of a selected one of the eyecup assemblies and the eyeglasses frame with one another. 
         [0085]    In an embodiment, a kit may be provided having eyecup assemblies and an eyeglasses frame. The kit may include a plurality of eyecup assemblies provided together with one another. At least one of the eyecup assemblies differ from another one of the eyecup assemblies. The eyecup assemblies have a seal material extending from an eyecup frame and are sized for engagement with facial portions surrounding both left and right eyes of a user. The eyecup assemblies have one or more attachment portions in attachment to the eyecup frame. The kit also includes an eyeglasses frame defining a pair of apertures. At least one lens may be disposed in each of the pair of apertures. One or more attachment devices are in attachment to the eyeglasses frame. The attachment devices of the eyeglasses frame and the attachment devices of the eyecup assemblies are configured for selective attachment with one another. This allows removable attachment of a selected one of the eyecup assemblies and the eyeglasses frame with one another. 
         [0086]    In various embodiments, kits may include eyecup assemblies with different seal materials. These differences may include, but are not limited to, differences in color, material, skin pattern (similar to a cell phone ornamental skin), or size. The seal material may relatively permanently affixed to an associated eyecup or it may be more readily removable and replaceable, such as by providing a seal skin that adheres to the eyecup or associated structure by means of an adhesive allowing later removal and replacement of the seal skin, in some embodiments by means of additional adhesive on one side of the seal skin. 
         [0087]    In another embodiment, a kit may include eyecup assemblies, but not a particular eyeglasses frame, and one or more of the eyecup assemblies differ others of the eyecup assemblies. The one or more attachment portions of the eyecup assemblies are configured for selective attachment with one or more attachment devices of an eyeglasses frame provided separately from the eyecup assemblies. This allows removable attachment of a selected one of the eyecup assemblies and the eyeglasses frame with one another. 
         [0088]    Whereas the foregoing description is in the context of representative embodiments, the invention is not limited to those embodiments. On the contrary, the invention is intended to encompass all modifications, alternatives, and equivalents as may be included in the spirit and scope of the invention, as defined by the appended claims.
