Rather, the intention is to cover all modifications, equivalents and alternatives falling within the scope of the disclosure.

DETAILED DESCRIPTION

[0020] FIG. 1 depicts an embodiment of a system 100 for contact lens insertion and removal. The system 100 includes a positioning member 102, a bead of adhesive material 104, and a contact lens 106.

[0021] The positioning member 102 may be lightweight and durable, and may be used for multiple insertions and removals of the contact lens 106. Although FIG. 1 depicts the positioning member 102 as a straight wand, in some embodiments, it may have a curved shape. For example, the positioning member 102 may be molded into an ergonomic shape for the benefit of a user of the system 100. The positioning member 102 may include or be made from paper, wood, plastic, or metal. For example, the positioning member 102 may include a dowel formed from wood or heavy rolled paper. Alternatively, the positioning member 102 may include a material that is easily sterilized, such as plastic or aluminum. Regardless of the material, the positioning member 102 may be rigid enough to enable precise positioning of the contact lens 106. In some embodiments, the positioning member 102 may be hollow to result in a better joint with the bead of adhesive material 104 and to reduce production costs.

[0022] The bead of adhesive material 104 may be soft enough to provide a cushion that absorbs excess pressure applied to the contact lens 106 by the positioning member 102 when the contact lens 106 is pressed against an eye during insertion. The adhesive material 104 may include a soft wax, such as beeswax, paraffin wax, low melting microcrystalline wax, low-melting natural wax, or combinations thereof. Additives, such as solid starch fillers may be used to adjust the tackiness or adhesive properties of the wax. Alternatively, or in addition, the bead of adhesive material 104 may include a gel, vinyl, or rubber. Another material that may be used in the adhesive material is medical grade silicone. Because it may come into contact with an eye, the bead of adhesive material 104 may be non-toxic.

[0023] It should be noted that the positioning member 102 and the bead of adhesive material 104 may be packaged together and preassembled. Alternatively, the positioning member 102 and the adhesive material 104 may be packaged and sold separately, to be assembled by a consumer before use.

[0024] During contact lens insertion, the positioning member 102 may be adhered to the contact lens 106 using the bead of adhesive material 104. The contact lens 106 may then be positioned onto an eye while the positioning member 102 is adhered to the contact lens 106. After the contact lens 106 is applied to the eye, the positioning member 102 may be disengaged from the contact lens 106 by applying at least a tapping motion to the positioning member 102. For example, the contact lens 106 may be tapped to the eye with an associated blink to disengage the contact lens 106 from the positioning member 102. In some cases, a pulling motion may also be used and accompanied by a twisting or sliding motion to disengage the positioning member 102 from the contact lens 106. The motion may further be associated with a blink to disengage the positioning member 102.

[0025] During contact lens removal, the positioning member 102 may be adhered to the contact lens 106 using the bead of adhesive material 104 while the contact lens 106 is positioned on an eye. The adherence may be the result of tapping the bead of adhesive material 104 to an edge of the contact lens 106. The contact lens 106 may then be slid and turned simultaneously using the positioning member 102 to remove the contact lens 106 from the eye without much pressure and without discomfort. After the contact lens 106 is removed from the eye, the positioning member 102 may be disengaged from the contact lens 106 by applying at least a pulling, sliding, or rotating motion to the positioning member 102 while the contact lens 106 is retained within a case (not shown).

[0026] A benefit of the system 100 is that insertion and removal of a contact lens may be easier than current methods of insertion and removal. For example, using the system 100 a contact lens may be inserted in approximately 3 seconds as opposed to typical contact lens insertion methods, which may take longer. Another benefit of the system 100 is that contact lens insertion and removal may cause much less discomfort as compared to systems that rely other mechanisms, such as fingers, tweezers, or a suction cup. The system 100 may further be more sanitary than traditional systems for insertion and removal of contact lenses. Other advantages may exist.

[0027] Referring to FIG. 2, an embodiment of a system 200 for contact lens insertion and removal is depicted. The system 200 may correspond to the system 100. In the system 200, a surface of the bead of adhesive material 104 may have a concave indentation 202 therein. The concave indentation may conform to a surface of the contact lens 106.

[0028] An advantage of the concave indentation 202 is that it may enable more surface area contact between the bead of adhesive material 104 and the contact lens 106. By creating more surface area contact, adherence between the positioning member 102 and the contact lens 106 may be strengthened. Other advantages may exist.

[0029] Referring to FIG. 3, an embodiment of a system 300 for contact lens insertion and removal is depicted. The system 300 may correspond to the system 100. In the system 300, the positioning member 102 may include a support structure 302 encased within the adhesive material 104. The support structure 302 may include a lip or bulb shape. Further, a surface of the support structure 302 may have a porous texture in order to adhere better to the bead of adhesive material 104.

[0030] An advantage of the support structure 302 is that the structure and shape of the bead of adhesive material 104 may be preserved after multiple uses. Another advantage is that less adhesive material may be used during manufacturing, thereby resulting in lower production costs. Other advantages may exist.

[0031] Referring to FIG. 4, an embodiment of a method 400 for contact lens insertion is depicted. The method 400 includes adhering a positioning member to a contact lens using a bead of adhesive material, at 402. For example, the positioning member 102 may be adhered to the contact lens 106.

[0032] The method 400 further includes maintaining the adherence of the positioning member to the contact lens while the contact lens is positioned onto an eye, at 404.

[0033] The method 400 also includes disengaging the positioning member from the contact lens in response to application of at least a tapping motion with the positioning member, at 406.

[0034] Referring to FIG. 5, an embodiment of a method 500 for contact lens removal is depicted. The method 500 includes adhering a positioning member to a contact lens using a bead of adhesive material while the contact lens is positioned on an eye, at 502. For example, the positioning member 102 may be adhered, or re-adhered, to the contact lens 106.

[0035] The method 500 further includes maintaining the adherence of the positioning member to the contact lens while the contact lens is removed from the eye.

[0036] The method 500 also includes disengaging the positioning member from the contact lens, at 506. For example, the positioning member 102 may be disengaged from the contact lens 106.

[0037] Referring to FIG. 6, an embodiment of a method 600 for forming a system for contact lens insertion and removal is depicted. The method 600 may include forming a positioning member with a support structure having a bulb shape, at 602. For example, the positioning member 102 may be formed with the support structure 302.

[0038] The method 600 further includes forming a bead of adhesive material on the positioning member, the bead of adhesive material encasing the bulb shape, at 604. For example, the bead of adhesive material 104 may be formed on the positioning member 102.

[0039] The method 600 also includes forming an indentation in a surface of the bead of adhesive material, at 606. For example, the indentation 202 may be formed in a surface of the bead of adhesive material 104.

[0040] A benefit of the method 600 is that by forming a positioning member that has a bulb shape, less adhesive material may be used to form a contact lens insertion and removal system. Further, by forming an indentation in a bead of adhesive material, more adhesion between a positioning member and a contact lens may be created. Other advantages may exist.

[0041] Although various embodiments have been shown and described, the present disclosure is not so limited and will be understood to include all such modifications and variations as would be apparent to one skilled in the art.
