The present invention relates to a contact lens case, more specifically relates to a contact lens case with lens data stowage compartments integrated therein.
Since the inception of contact lenses circa 1965, various strategies have been employed for the efficient and practical storage of contact lenses during periods of non-use thereof. In general, contact lens cases fall into two categories, namely, those employed for short term storage of lenses, typically not exceeding a day, and those for longer term storage. In the latter case, a larger quantity of saline or other suitable solution is required to assure thorough soakage and thereby cleaning of the hydrophilic contact lenses from debris or bacteria that they may have been acquired during a longer period of usage. In the case of contact lens cases of the first category, a smaller quantity of saline solution is required. However, regardless of the type of case required, a persistent problem has been that certain users will eventually lose or damage a particular contact lens and thereupon generally will not know the spherical or power measurement, axis, diameter, or other data about a lost or damaged lens, thereby requiring a visit to an optometrist in order to replace or reorder the contact lens.
Therefore, there is a need for providing contact lens users convenient storage and easy access to contact lens data for reordering or confirming their contact lens information. Moreover, there is a further need to improve indicia of existing contact lens case to reduce the likelihood of misplacement of a pair of contact lenses within a contact lens case.
In one embodiment, the present invention is directed to a contact lens case having integrated lens data stowage compartments. The contact lens case comprises a left and right bowl section in an upper portion of a case body, each of the bowl section having a closed bottom and an open top detachably closed by a closure cap, and two lens data stowage compartments in a lower portion of the case body, each compartment underneath one bowl section, assessable from a side or a lower base of the contact lens case, and the height of the compartments proportioned for receipt of a lens data sheet having thereon lens data corresponding to a contact lens located in the bowl section thereabove, whereby the lens data stowed in each compartment can be viewed or accessed from the contact lens case.
An object of the present invention is to provide a contact lens carrying case which has integrated lens data stowage compartments for convenient storage and retrieval of contact lens data. In the event of damage, loss or natural deterioration of a lens, one can readily obtain the characterizing data of the contact lens by inverting the carrying case and observing its relevant parameters in respective compartment or through the lower base of the contact lens case, or alternatively by viewing the lens data through a transparent bowl section.
Another object of the invention is to provide an alert to a case user upon removal of contact lens from an eye, as to which lens bowl a particular lens should be placed in, for example, using the color red from a light-emitting LED to denote a right lens bowl and a second color to denote the proper bowl placement of the other lens.
It is a further object to minimize the need for a visit to an optometrist in the event that a contact lens is damaged or lost, thereby facilitating ease of reordering of a lost contact lens.
The advantages of the present invention will become apparent from the following description taken in conjunction with the accompanying drawings showing exemplary embodiments of the invention.
It is noted that in the drawings like numerals refer to like components.

In some embodiments, the contact lens or ophthalmic case of the present invention has integrated lens data stowage compartments. The contact lens case includes a left and right bowl section in an upper portion of a case body for storing a pair of contact lenses and two lens data stowage compartments in a lower portion of the case body. Each of the bowl section has a closed bottom and an open top detachably closed by a closure cap. Each compartment is positioned underneath one bowl section, and is assessable from a side or a lower base of the contact lens case. The height of the compartments is proportioned for receipt of a lens data sheet having thereon lens data corresponding to a contact lens located in the bowl section thereabove. The lens data stowed in each compartment can be viewed or accessed from the contact lens case.
Now referring to the drawings,
The contact lens case 10 further includes two lens data stowage compartments, namely, a left compartment 50 and a right compartment 60 in the lower portion of case body 20. As shown in
In the embodiment shown, case body 20 is in a form of generally rectangular, planar platform, with the bottommost of the case body forming a flat lower base 26 of the contact lens case. Each of the two compartments 50, 60 is in the form of a sleeve, formed by a short hollow segment immediately above the lower base 26 of case body 20. Each compartment has an opening in a form of elongated horizontal slot on one side of the platform. In the embodiment show, left compartment 50 has an opening 52 on the left side 24a of the case body and right compartment 60 has an opening 62 on the opposing side 24b. Alternatively, a similar opening of the compartment can also be positioned at the front or rear side of the case body. Two compartments are separated from each other by a partition at the middle of the hollow segment. The height of compartments 50, 60 is proportioned for receipt of a lens data sheet. The lens data sheet has printed thereon lens data corresponding to a contact lens located in the bowl section thereabove and can be inserted into respective compartment through its opening.
The lens data sheet may be in the form of aluminum foil, plastic or paper label, film, or membrane, and has printed thereon of lens data for one corresponding contact lens. The lens data can be printed on one surface or both surfaces of the lens data sheet. For the purpose of the present invention, the lens data may include prescription of the contact lens for respective eye, curvature of the contact lens, diameter of the contact lens, and/or other desired contact lens related information. The lens data is typically provided on the contact lens holding vial by the manufacturer. A foil or the like containing lens data may be readily removed from the original lens holding vial and placed into the lens data stowage compartment underneath corresponding bowl section into which the contact lens is to be kept. The lens data sheet may be cut by the user to fit into a compartment. In contact lens case 10, the lens data sheets for a pair contact lenses can be inserted into compartments 50, 60 through their respective openings 52, 62 described above.
In some embodiments, the lower base 26 of case body 20 includes a transparent display area overlaid with the two compartments 50, 60. Alternatively, the lower base 26 may include two transparent display areas 26a, 26b, each overlaid with one compartment, see
In a further embodiment, the transparent display area of the lower base 26 may be a magnifying surface. The lens data can be more easily viewed through the magnifying surface by the user or contact lens vendor for reordering the same contact lenses.
In another embodiment, the case body 20 may be made of a transparent material, and the lens data on lens data sheets placed in compartments 50, 60 can be viewed from the upper side of the contact lens case through transparent bowl sections when the closure caps are removed. Known transparent plastic material compatible with contact lens and contact lens solutions can be used for the case body. In this embodiment, the lens data on lens data sheets may be orientated to face the bowl sections. As can be appreciated, in this configuration the lens data underneath the transparent bowl sections can also be used as an indicia for respective contact lens. Alternatively, the lens data sheets may have the lens data on both surfaces, and the lens data may be viewed through either the bowl sections or the lower base of the contact lens case.
As shown in
Each lid 170, 180 may have a planar part 172, 182 complementary to size and shape of respective compartment and has one side thereof pivotally connected to a portion of circumferential edge 154, 164 or to the case body, see
Each lid 170, 180 and respective compartment 150, 160 have a locking or closure mechanism to secure a closed lid to respective compartment. In the embodiment shown in
As shown in
Moreover, one or both lids 170, 180 may further include an indicia for respective compartment corresponding to the left or right bowl section thereabove, see
To prevent loss of the lens data sheets, or misplacement of the lens data sheets between the two compartments when accessing the information, each lens data sheet may be secured to the base of the compartment or to the internal surface of the lid with an adhesive or the like. If the lid has a transparent display area, the lens data sheet is orientated with the lens data facing the transparent display area. Alternatively, if the bowl section is transparent for viewing the lens data therethrough, the lens data sheet may be orientated with the lens data facing the bowl section. As described above, optionally the lens data may be provided on both surfaces of a lens data sheet and the lens data can be viewed through the transparent display area of the lid and through a transparent bowl section.
In the embodiment shown in
Similar to contact lens case 100, planar part 172a of lid 170a may include one transparent area overlaid with the two compartments for viewing the information on the lens data sheets. Alternatively, lid 170a may include two transparent areas, each overlaid with one compartment. Each transparent area may include a magnifying surface. Moreover, lid 170a may further include an indicia for one or both compartments corresponding to the left or right bowl section thereabove. For example, the letter L and R can be placed on the left side and right side of lid 170a, on the external surface, internal surface or both surfaces of the lid.
Different from the embodiments described above, in contact lens case 200 the two lens data stowage compartments 250, 260 are substantially spaced apart, and each is on one side of bridge section 225. As shown in
As further shown in
The case body in the embodiments described above may be made of a suitable plastic material, such as polyethylene, by plastic molding. The material forming the bowl sections is compatible with contact lens and contact lens solution. Existing contact lens plastic materials can be used for the purpose of the present invention. The caps and lids of the contact lens case may be made of the same plastic material, or a different material. In some embodiments, the lids connected to the case body may be made by plastic molding into an integral part of the case body. In some embodiments, the lids and/or the case body may be made of a transparent or translucent material.
As can be appreciated, the height of the lens data stowage compartments only needs to sufficient for stowing the lens data sheet, which is typically in the form of aluminum foil or plastic film. As such, the height of the compartments is substantially less than the height or depth of the bowl section, see
The contact lens case of the present invention is particularly advantageous for the users to store and to access the lens data for reordering. In the event of loss or damage of a contact lens, the user can conveniently retrieve the lens data by opening corresponding lens data stowage compartment, or directly view through a transparent lower base of the contact lens case, or view through a transparent bowl section of the contact lens case. This avoids an unnecessary trip to visit an optometrist and cost associated with it. Moreover, contact lens users usually maintain easy access to their contact lens case on a daily basis. Therefore, it is more convenient and less time consuming to retrieve lens data from the instant contact lens case than to find the same information saved in files or on computer.
Furthermore, the present invention also addresses the problem of inadvertent misplacement of the lens of one eye into the lens bowl within the contact lens case, intended for the other eye. Therefore, two common problems of contact lens users are herein addressed by the instant contact lens case.
While the present invention has been described in detail and pictorially shown in the accompanying drawings, these should not be construed as limitations on the scope of the present invention, but rather as an exemplification of preferred embodiments thereof. It will be apparent, however, that various modifications and changes can be made within the spirit and the scope of this invention as described in the above specification and defined in the appended claims and their legal equivalents.
