Contact lenses are worn directly on the eye and are widely used to correct vision problems. Consequently, lenses are manufactured with different characteristics or prescriptions as needed to correct the vision of different lens wearers. Often, lens wearers must distinguish between a right lens and a left lens. This is necessary because many lens wearers need a different prescription to correct the vision in their left eye as compared to the prescription needed to correct the vision in their right eye.
Traditionally, contact lenses have been either rigid (hard) or soft. Soft contact lenses are often disposable after a period of use. Consequently, a quantity of soft lenses are often packaged together and sold to supply the wearer with enough lenses to last for a period of time, such as six months or a year. A typical package has a “blister” molded out of high quality polypropylene. The blister contains a single contact lens and a quantity of solution needed to keep the lens hydrated. A film is then sealed over the blister and secured to the margin area around the blister so as to seal the lens and the hydrating solution within the blister. When a lens wearer needs to use the lens, the film is pealed away from the blister to allow access to the contact lens inside the blister.
One problem that many lens wearers face is keeping track of lenses with different prescriptions and knowing which lens corresponds to which of the wearer's eyes. Lenses are typically supplied by the manufacturer with a listing of the parameters of the lenses (such as the power, diameter, base curve, etc.), but there is no indication from the manufacturer as to in which eye a particular lens is to be worn. In the past, this information has not been used by the manufacturer, but has been the concern of the dispensing optometrist. Consequently, unless the dispensing optometrist indicates which eye a set of contact lenses are to be used in, the wearer must then ascertain this important fact for themselves. If the prescriptions needed for a wearer's two eyes are only slightly different, it may be very difficult, if not impossible, for the wearer to figure out for himself or herself in which eye to use a particular new lens.
Moreover, even if the dispensing optometrist designates whether a set of lenses is for a left or right eye on an outer package, the individual contact lens packages inside that outer package will not include that information. Once the outer package has been opened, it is typically not fully resealable. Consequently, individual lens packages may fall out of the outer package when stored. In such a case, individual lens packages from different outer packages designated for different eyes may easily become mixed up without the wearer being able to tell in which eye to use a given lens.
The primary packaging for a contact lens includes an indicator on the primary packaging that indicates whether said contact lens is for use in a right or left eye of a lens wearer. A method of packaging a contact lens includes a lens manufacturer marking a contact lens package with an indicator as to whether a contact lens in the marked package is to be worn in a left eye or a right eye.
The accompanying drawings illustrate various embodiments of the present system and method and are a part of the specification. The illustrated embodiments are merely examples of the present system and method and do not limit the scope of the claims.
Throughout the drawings, identical reference numbers designate similar, but not necessarily identical, elements.
The present specification describes methods, lens packaging systems, and devices for designating to a lens wearer on primary packaging from a lens manufacturer whether a lens is configured for use in the wearer's right or left eye. Consequently, the lens wearer is able to check a designation for a particular lens to ascertain whether the prescription of the lens matches the wearer's right or left eye.
As used herein and in the appended claims, the term “primary package,” “primary packaging,” or “primary case” will be used to refer to the packaging in which a contact lens or a supply of lenses are placed during the manufacturing processes and the packaging in which the lens or supply of lenses is then provided either directly to a lens wearer or to a dispensing optometrist or other eye care professional. Consequently, primary packaging is distinguished from any container or packaging that a lens may be placed in subsequent to being received by the lens wearer, such as a lens container in which the lenses are stored or cleaned during the period they are in service and after having been removed from the primary packaging of the manufacturer. If, however, the lenses are repackaged commercially before being provided to a lens wearer, that repackaging may still be considered “primary packaging” as defined herein. “Primary packaging” may refer to either or both of the packaging used to package individual lenses or the outer or shipping packaging used to package together a quantity of individually packaged lenses.
According to one of many exemplary embodiments described herein, a contact lens primary package contains at least one contact lens and includes an indicator on the primary package indicating whether the at least one contact lens is meant for use with a wearer's right eye or left eye. Specifically, the indicator may be provided on the primary package by the manufacturer of the lens. Alternatively, the indicator may be provided on the primary package by a lens wholesaler or a lens re-packager. In either case, the packaged lens or lenses are provided to the wearer or the wearer's eye care professional with the indicator already in place on the primary packaging.
In another exemplary embodiment, the present specification describes a primary package containing contact lenses to be worn in a right eye and contact lenses to be worn in a left eye. The primary package includes an outer or shipping package containing a quantity of individually packaged contact lenses, where the individual contact lens packages are marked with an indicator prior to shipment designating whether that particular lens is for use in the wearer's left eye or right eye.
In another exemplary embodiment described herein, contact lens primary packaging includes an indicator that indicates whether a contact lens in the packaging is to be worn in a wearer's left eye or right eye, where the primary package is marked with the indicator as containing a left eye lens or a right eye lens at the same time the package is marked with a prescription applicable to the lens in the package. This embodiment also includes a method of packaging a contact lens in which the contact lens is placed in the primary package and the package is marked with an indicator as containing a left eye lens or a right eye lens at the same time the package is marked with a prescription applicable to the lens therein.
It should be noted that the packaging (1) described here, and in the other examples given below, is primary packaging produced by the lens manufacturer and then provided to the lens wearer. When a lens wearer needs the lens (4), the foil (3) is pealed from the package (1) as shown in
As described above, in the past, there has been no way for the lens wearer to ascertain from the primary package whether the lens is of the prescription for the wearer's right or left eye. Consequently, according to the principles described herein, an indicator (7) is provided on the primary package (1). This indicator (7) will indicate to the lens wearer whether the particular lens (4) in the package (1) is configured for the wearer's right or left eye.
The indicator (7) can take any of a myriad of forms. In the illustrated example, the indicator (7) is a letter, e.g., “L” for left or “R” for right. However, the indicator (7) can alternatively be any symbol or device that allows the lens wearer to determine whether the package (1) contains a right eye lens or a left eye lens. For example, the indicator (7) can be, but is not limited to, a letter, a word, a symbol, a shape, a color, or any other device that allows the lens wearer to distinguish a package containing a right eye lens from a package containing a left eye lens.
The indicator (7) may be printed or disposed on the foil (3) or the molded portion (2) of the package (1). The indicator (7) may be the color of the foil (3) or the color of some other portion of the package (1) such as the molded portion (2). Alternatively, the indicator may be the package (1) itself, such as incorporating a different package shape for a package containing a right eye lens compared to a package containing a left eye lens. Again, any device that allows the lens wearer to distinguish a package containing a right eye lens from a package containing a left eye lens can be used under the principles described herein.
Additionally, as mentioned above, the primary packaging can include an outer or shipping package that also bears an indicator of the eye for which the packaged lenses are intended.
In the present example, all of the individually packaged lenses (12) in the outer package (13) are of the same prescription and are intended for use in a particular eye of the wearer. Consequently, the outer package (13) may also or alternatively bear an indicator (7) that indicates whether the individually packaged lenses (12) are right eye lenses or left eye lenses. As indicated above, the indicator (7) can be any device that allows the lens wearer to distinguish a package containing right eye lenses from a package containing left eye lenses.
The indicator (7) may be printed or disposed on the outer package (13) at a variety of locations. For example, as shown in
Alternatively, as shown in
The principles described herein can be applied to any of the myriad primary packaging arrangements that have been proposed or that may in the future be proposed for contact lenses. In another example, illustrated in
As shown in
When the lens is needed by a lens wearer, the foil cover (26) is pealed back as shown in
Referring again to
Additionally, an indicator (7) may again be placed on the primary packaging (176) to indicate whether the lens in the package is configured for a wearer's right or left eye. In the example of
Referring first to

Thus, the receptacles (64, 65) of the base (62) receive the boats (55) of the two cases (50). The base (62) may further include indicators (68, 69), one for each receptacle, which indicate the number of days that have elapsed since the package (50) currently in the receptacle (64, 65) was placed therein.
Referring to
As shown in
The tubes (70, 72, 74, 76) may each contain a specific number of lenses which suits the wearing modality or the purchasing preferences of the wearer, such as a six month supply of two-week lenses. When one package (50) is removed, the next one falls down into place.
A system sent to a customer may also include a bottle of multipurpose contact lens solution (82). This bottle could be equipped with a pump (84) or some other kind of push down system so that it dispenses an exact amount of solution (such as 3 ml) with one push. This would allow the bottle (82) to stay in place during use instead of a wearer having to pick up the bottle and carefully squirt out 3 ml of solution to fill the boat (55) when a contact lens (4) is placed in the package (50) for temporary (overnight) storage. The system supplied could also include a small bottle (86) for drops of a specialized fluid, such as wetting drops.
Referring to
Each lens package (123) is sealed with a cap (94). Each cap (94) may include lens parameter information (115), as well as a left and right designation (94). The left/right designation (94) may include a check placed next to the word or a symbol for left/right. This check mark may be applied when the lenses are pulled from inventory to be supplied to a wearer. Alternatively, an inventory of pre-marked packages of both left and right eye lenses may be maintained. In still another alternative, an inventory of pre-marked caps of both left and right eye (possibly of a different color) may be maintained so that the respective packages (123) can be designated as being for one eye or the other during assembly of a package. In this manner, the packages are readily distinguishable from one another as containing a left eye lens or a right eye lens.
Left/right indicators (116, 117) may be provided on the substrate (112). These indicators (116, 117) instruct the lens wearer in which receptacle (114) to place a package (123) bearing a right eye lens and in which receptacle (114) to place a package (123) bearing a left eye lens.
The base (112) may also include indicators (118, 119) for each receptacle (114) to indicate the number of days elapsed since the package (123) currently in that receptacle (114) was placed there. The indicators (118, 119) may be electronic or electrochemical indicators, and may be part of one assembly to save cost. A switch or triggering device in the receptacles (114) may used to reset the indicators (118, 119). Thus, the indicators (118, 119) may be prompted to indicate an elapsed number of days by counting from the moment the reset device is triggered, which would occur when the old package (123) is pressed out of the receptacle (114) of the base (112) or when a new package (123) is pressed in. The indicators (118, 119) may also change color once a certain number of days have passed. A battery may be provided to power the electronic indicators. Such a battery might last for a year or more. This would eliminate the need for the wearer to change it. The electronic components, such as the indicators (118, 119) and switches, could be insert molded into the base (112) when the base (112) is formed by injection molding.
As shown in
Alternatively, the individual packages (123) can be arranged in other configurations for shipping. For example, the individual packages (123) can be arranged in an array with breakable links between the packages (123) for forming them temporarily into a flat, interconnected grid that is then placed in shipping packaging, perhaps stacked with other such grids, for shipment.
An indicator (206) is provided on the boat (208), for example, on the foil seal (216), to indicate whether the lens in the package (202, 204) is for a wearer's right eye or left eye. As before, the indicator (206) can be any device that allows the wearer to determine whether the package (202, 204) contains a right eye lens or a left eye lens.
After the individual packages (10) are provided to a lens wearer, the primary packaging shown can continue to be used as a daily storage receptacle for the lenses in addition to having served as primary packaging. Two of the individual packages (10) can be secured together as shown in
As shown in
Additionally, each package (10) may include an indicator of whether it contains a right eye lens or a left eye lens. This indicator may be the same as the indicators described above. Additionally or alternatively, as shown specifically in
In a method of doing business to provide lenses to a wearer, a quantity of each type of individually packaged lens may be provided to the lens wearer. The lens wearer can then take two differently colored packages as needed, connected the packages as shown in
The various primary packages described herein can be sterilized by autoclave, preferably at a temperature of 120° C. for a period of 20-30 minutes. Additionally or alternatively, the various primary packages described herein may be sterilized by any other means shown to provide the required degree of sterilization.
Additionally, the present specification discloses a number of novel methods for doing business in the area of contact lenses in connection with the packaging systems described above. As shown in
This method may also be described as producing contact lens primary packaging that includes an indicator that indicates whether a contact lens in the packaging is to be worn in a wearer's left eye or right eye, where the primary package is marked with the indicator as containing a left eye lens or a right eye lens at the same time the package is marked with a prescription applicable to the lens in the package. This method may also be described as producing primary packaging for a contact lens where the package is marked with an indicator as containing a left eye lens or a right eye lens at the same time the package is marked with a prescription applicable to the lens therein.
The exemplary method may also further include stockpiling a volume of contact lenses in primary packaging having an indicator on the primary packaging indicating that the lenses are for use in a wearer's right eye (201), stockpiling a second quantity of contact lenses in primary packaging having an indicator on the primary packaging indicating that the lenses are for use in a wearer's left eye (201), and responding to an order for either or both left and right eye contacts by shipping the requested contact lenses, according to the order, in the primary packaging that indicates in which eye each lens is to be used (202, 203).
Another exemplary method disclosed herein may be described as a method of doing business in the sale or distribution of contact lenses including: (a) receiving an order from a contact lens wearer for a supply of contact lenses (202) designed to be worn for a prescribed number of days, the order including lenses of a first prescription for use in the right eye of the wearer and lenses of a second prescription for use in the left eye of the wearer; and (b) shipping the contact lenses requested in the order (203) to the wearer in an outer package containing a plurality of individual contact lens packages, the plurality of individual contact lens packages comprising two different package types, a first of the package types containing lenses for the first prescription and the second of the package types containing lenses for the second prescription, the first and second package types being readily distinguishable from one another.
A method of filling an order for contact lenses described herein includes: (a) placing a contact lens with one prescription for the left eye in a package that indicates the contact is for use in the left eye; (b) placing a contact lens with a second prescription for the right eye in a package that indicates the contact lens is for use in the right eye; and (c) shipping the order.
Another method of selling or distributing contact lenses described herein includes: (a) receiving an order from a contact lens wearer for a supply of contact lenses designed to be worn for a prescribed number of days, the order including lenses of a first prescription for use in the right eye of the wearer and lenses of a second prescription for use in the left eye of the wearer; (b) shipping the contact lenses requested in the order to the wearer in an outer package containing a plurality of individual contact lens packages, the plurality of individual contact lens packages including two different package types, a first of the package types containing lenses for the first prescription and the second of the package types containing lenses for the second prescription, the first and second package types being readily distinguishable from one another.
The preceding description has been presented only to illustrate and describe embodiments of the exemplary systems and methods. It is not intended to be exhaustive or to limit the systems and methods to any precise form disclosed. Many modifications and variations are possible in light of the above teaching.
