BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to the field of insertion and removal devices and more specifically relates to a handheld contact applicator specifically designed for the insertion and removal of contact lenses to provide contact lens wearers a simple and sanitary means of handling their lenses.
2. Description of the Related Art
Millions of Americans suffer from problems related to their vision. Whether one has a classic case of Myopia (nearsightedness), Hyperopia (farsightedness), Astigmatism (distorted vision), Presbyopia (the need for bifocals) or more than one of the above, not being able to see clearly can effect virtually every aspect of a person's life. Most people correct their vision by wearing eye glasses or contact lenses. In particular, contact lenses are an extremely popular solution to the problems associated with poor vision. Contacts are so popular in fact, that nearly 24 million Americans wear them. According to statistics compiled by the University of Michigan, Kellogg Eye Center, of these 24 million, nearly 75% opt for soft lenses, while others choose to wear hard, rigid gas permeable or extended wear contacts. Regardless of the variety of contacts an individual chooses to wear, a consistent regimen of care must be taken in order to ensure the optimal health of the eye. Contact lenses are tiny, curved plastic discs, which are designed to be placed directly over the cornea and are held in place by a thin film of tears, as well as by surface tension (capillary action.)
Traditionally, most people insert their contact lenses one at a time, by placing each lens on the tip of the index finger and directly setting it over the cornea. While a fresh, clean pair of contact lenses can vastly improve one's vision, a pair that is soiled can potentially damage one's eyesight. When lenses are not cleaned and handled properly, dirt, oil and bacteria are directly deposited into the eye, via the contact. Resulting in everything from irritation, a scratched cornea, eye infections and blurred vision, wearing a pair of contaminated contact lenses can result in permanent intolerance to contacts, and in some extreme cases can even cause blindness.
While most conscientious contact lens wearers wash their hands before inserting their contact lenses, many others do not. Overlooking the importance of freshly washed hands, many contact lens wearers simply do not realize the dangerous consequences of handling contacts and perhaps most importantly, touching the eye, with unclean hands. Additionally, many contact lens wearers experience difficulty inserting and removing their lenses. Because of their very size and shape, properly inserting or removing a contact lens can be a daunting task, especially considering that most contact lens wearers cannot see clearly during this process. A sanitary and convenient means for insertion and/or removal of contacts into eyes is desirable.
Various attempts have been made to solve the above-mentioned problems such as those found in U.S. Pat. No. 4,378,126 to Leonid Procenko; U.S. Pat. No. 4,093,291 to Herbert L. Schurgin; U.S. Pat. No. 4,026,591 to John A. Cleaveland; and U.S. Pat. No. 4,565,396 to John M. Larimer. This prior art is representative of contact lens accessories. None of the above inventions and patents, taken either singly or in combination, is seen to describe the invention as claimed.
Ideally, a handheld applicator specifically designed for the insertion and removal of contact lenses will provide contact lens wearers with a simple and sanitary means of handling their lenses and, yet would operate reliably and be manufactured at a modest expense. Thus, a need exists for a reliable handheld contact applicator system to avoid the above-mentioned problems.
BRIEF SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known contact accessories art, the present invention provides a novel handheld contact applicator. The general purpose of the present invention, which will be described subsequently in greater detail is to provide a safe and efficient means for inserting and removing contact lens from eye(s).
A handheld contact applicator system is disclosed herein, in a preferred embodiment, comprising: a handheld contact applicator assembly having a handle body (having a proximate end, a distal end, an aperture, and a length), an inserter/remover assembly (having a shaft, a release button, and a contact engager); wherein the handheld contact applicator system comprises the handheld contact applicator assembly. The handheld contact applicator assembly comprises the handle body and the inserter/remover assembly in cooperative and functional combination.
The handle body comprises the proximate end, the distal end, the aperture, and the length, as mentioned; wherein the parameters of the handle body are defined by the proximate end, and the distal end having the length thereby defined; the aperture passes through the handle body.
The inserter/remover assembly comprises the shaft, the release button, and the contact engager; wherein the contact engager is preferably flexible to avoid contact-injury to the eye. The contact engager is normally concave-tensioned, wherein the contact engager engages a contact lens via surface tension (capillary action) for insertion. In a similar but reverse manner the contact engager disengages the contact lens via breaking capillary action for removal via flexing the contact engager to a convex positioning temporarily (other means of removal may be employed).
In preferred embodiments the handheld contact applicator assembly comprises plastic or rubberized material or the like (other suitable equivalents may be used). The plastic, when used, is soft to prevent eye injury and also able to be sterilized to prevent harboring of bacteria and the like.
Relationally speaking, the inserter/remover assembly is nearest the proximate end of the handle body. The inserter/remover assembly is in mechanical communication with the handle body; the shaft passing through the aperture perpendicular to the handle body, the release button located on a terminal end of the shaft and the contact engager located opposing the release button on a leading end of the shaft, The release button is manually activated when depressed, to facilitate release for insertion and alternately to couple to for removal, the contact lens touch-coupled to the contact engager. As such, the handheld contact applicator assembly is structured and arranged to facilitate the insertion and the removal of the contact lens in a remote capacity in order to effectively eliminate finger to eye contact. The handheld contact applicator is also able to be used as a hygienic means of adjusting the contact lens which have slipped off a cornea.
It should be appreciated that when referring to the handheld contact applicator system disclosed herein that the contact lens is selected from the group consisting of soft-lens, hard-lens, gas-permeable-lens, and extended-wear-lens. This list is exemplary and is not intended to be limiting in any way.
A method of using a handheld contact applicator system is also disclosed herein comprising the steps of: adhering a contact lens to a contact engager of a handheld contact applicator assembly (via surface tension—using liquid or the like), placing the contact lens onto an eye surface, and pressing a release button to release the contact lens and couple the contact lens onto the eye surface for wear. Thus remote insertion may occur without direct use of a finger. The method may further comprise the step of removing the contact lens from the eye surface when wearing is completed, also without direct use of at least one finger adjacent the eye surface.
The present invention holds significant improvements and serves as a handheld contact applicator system. For purposes of summarizing the invention, certain aspects, advantages, and novel features of the invention have been described herein. It is to be understood that not necessarily all such advantages may be achieved in accordance with any one particular embodiment of the invention.

DETAILED DESCRIPTION
As discussed above, embodiments of the present invention relate to a contacts accessory and more particularly to a handheld contact applicator as used to improve the efficiency, hygiene, and safety of contact insertion and removal.
Generally speaking, the handheld contact applicator comprises a specially designed handheld mechanism comprised of an elongated, ergonomically shaped handle, at the top of which is a circular shaped cup-like lens holder (contact engager) preferably manufactured of soft and flexible rubber material.
This disc-like cup may be designed to easily hold virtually any standard soft, hard, or rigid gas permeable lens. The elongated shaft of the handheld contact applicator may be sized and shaped appropriately to effectively ensure a comfortable grip. Manufactured of lightweight plastic or comparable material, the handheld contact applicator handle may measure approximately 7 inches in total length and 1⁄2 inch in width. The actual flexible rubber contact lens cup holder may be a concave circle measuring between 1⁄4-5⁄8 of an inch in diameter. Positioned at the proximate end of this handle may be a simple release lever, configured in the form of an easily depressed button which is internally connected to the actual contact lens suction cup, gently releasing or removing the inserted contact lens via a simple spring or comparable mechanism which secures the cup to the shaft.
Use of the handheld contact applicator may be relatively simple and straight forward. After washing the hands, the user may comfortably grasp the handheld contact applicator in hand. The user may then open their contact lens case, retrieving the contact lens by hand and placing it directly onto the circular shaped disc-like suction cup, located at the top of the unit. Alternately, the contact lens wearer could use the handheld contact applicator to actually lift their lens out of the case, by using the rubber contact lens holder as a scoop on which to retrieve the lens. The user may then position the handheld contact applicator so that the contact lens was positioned directly over the cornea. The user may then simply depress the integrated release handle located at the base of the unit shaft, gently releasing the contact lens directly onto the eye (surface.)
This process may then be repeated with the remaining contact. After wear, the user may remove their contact lenses by once again utilizing the handheld contact applicator. Positioning the lens holder in front of the handheld contact applicator, the user may lightly touch the cup to their contact, thus gently pulling the contact from the eye. The user could then drop the contact lens into its storage case, utilizing the unit to remove their second lens. The user may then simply rinse the cup holder clean and store the unit alongside their other eye care accessories.
There are many significant benefits and advantages associated with the handheld contact applicator. Foremost, the handheld contact applicator may offer consumers a hygienic means of handling their contact lenses. Providing a safe and effective means of inserting and removing contact lenses, consumers should appreciate that the handheld contact applicator may offer a sanitary alternative to touching contact lenses with one's fingers or hands. Additionally, because use of the product may eliminate the need to directly touch the eye, the handheld contact applicator could greatly reduce the potential for eye infections and vision problems that are associated when germs and bacteria are deposited into the eyes via transfer from the hands.
Easy to use, the handheld contact applicator may aid in inserting contact lenses, in a few, simple steps. This benefit should prove especially advantageous to teens who are wearing contacts for the first time and who might find it difficult to insert or remove their lenses. Further, consumers who suffer various maladies such as arthritis and other medical conditions that can compromise their manual dexterity should greatly appreciate the ease of which the handheld contact applicator may enable them to insert and remove their contacts. Consumers should also appreciate that the handheld contact applicator may be used with virtually any contact lens. Safe for soft, hard, gas permeable and extended wear lenses, the handheld contact applicator is able to be used by the majority of contact lens wearers. Another advantage is found in the unique design of the unit. Although specially intended to insert contact lenses, the unique, soft disc of the handheld contact applicator may also be used as a hygienic means of adjusting contact lenses which have slipped off the cornea or shifted out of place in the eye.
The handheld contact applicator is a practical product invention which provides contact lens wearers a sanitary method of inserting and removing their contacts. Simple to use, this innovative product may prove an invaluable tool in the care of contact lenses, resulting in clear vision and healthy eyes.
