The present invention relates to a device for attaching a contact lens to an eye, and more particularly to a portable device capable of easily and sanitarily attaching a contact lens to an eye.
In general, a contact lens is attached to the cornea of an eye in order to correct eyesight or to remedy the eye or for the purpose of beauty. The Korean eyewear industry states and statistics in the year of 2017 reveal that the percentage of Korean adults who simultaneously use glasses and contact lenses is 8.5% and that the number of users who use contact lenses has gradually increased over the years. Also, in recent years, the use of contact lenses by, particularly, students and young people has rapidly increased due to an increase in leisure time and an increase in various media such as social network services (SNSs). Meanwhile, in the case in which contact lenses are attached to and detached from eyes using fingers of a user, such attachment and detachment are inconvenient and the contact lenses may be contaminated. For these reasons, the demand for a tool or device capable of sanitarily attaching and detaching contact lenses has also increased with an increase in use of contact lenses. As a conventional contact lens wearing device, examples of an integrated device including an eye opening means configured to open eyelids and a wearing means configured to move a contact lens held thereby toward the cornea of an eye are disclosed in Korean Registered Utility Model No. 20-0330914, Korean Registered Patent No. 10-1947772, and Korean Patent Application Publication No. 10-2011-0095568.

As shown in
In general, the first clamp 110 and the second clamp 120 are coupled to each other so as to intersect each other about a pivot point 130 in order to open the eyelids in an upward-downward direction by increasing or decreasing the angle therebetween.
A first grip portion 112 having a first circular grip hole 112a, through which a finger is inserted to grip the first grip portion 112, formed therein is installed at one end of the first clamp 110. A first arm 113, made of any one of a metal material and a synthetic resin material, may be connected to the first grip portion 112.
The first arm 113 includes two branches extending from the first grip portion 112 so as to be opposite each other in the state of being spaced apart from each other. Each branch of the first arm 113 has a shape in which the branch extends parallel to the first grip portion 112, is bent upwards at an angle of about 45 degrees, extends a predetermined length, is bent in a V shape, and extends parallel to the first grip portion 112.
The first eye opening means 114, configured to be brought into tight contact with a corresponding one of the eyelids, may be installed at the tip end of the first arm 113.
Ends of the two branches of the first arm 113, which are opposite each other, are inserted into a curved upper closed arc member 114a of the first eye opening means 114. An upper arc finish member 114b may be coupled to an open end of the upper closed arc member 114a, i.e. the front end of the upper closed arc member 114a.
Each of the upper closed arc member 114a and the upper arc finish member 114b may be made of a silicone material in order to prevent skin damage and to achieve soft but tight contact. In addition, a curved protrusion 114c, configured to lift an upper eyelash at the time of opening the eye, may be formed on the upper surface of the upper closed arc member 114a.
The curved protrusion 114c is formed so as to have a length equal to or slightly less than the arc length of the upper closed arc member 114a. The curved protrusion 114c may have a flap shape that faces upwards.
The second clamp 120, which is installed so as to intersect the first clamp 110, is made of the same material as the first clamp 110 and is manufactured so as to have the same shape as the first clamp 110. The second clamp 120 is coupled to the pivot point 130 in a direction in which the second clamp 120 is opposite the first clamp 110.
A second grip portion 122 having a second circular grip hole 122a, through which a finger is inserted to grip the second grip portion 122, formed therein is installed at one end of the second clamp 120. A second arm 123, made of any one of a metal material and a synthetic resin material, may be connected to the second grip portion 122.
The second arm 123 includes two branches extending from the second grip portion 122 so as to be opposite each other in the state of being spaced apart from each other. Each branch of the second arm 123 has a shape in which the branch extends parallel to the second grip portion 122, is bent downwards at an angle of about 45 degrees, extends a predetermined length, is bent in a V shape, and extends parallel to the second grip portion 122.
The pivot point 130 is a portion at which the first arm 113 and the second arm 123 are connected to each other so as to intersect each other. Preferably, the pivot point 130 is rotatably installed at the middle of the inclined portion of each of the first arm 113 and the second arm 123.
The second eye opening means 124, configured to be brought into tight contact with a corresponding one of the eyelids, may be installed at the tip end of the second arm 123.
Ends of the two branches of the second arm 123 are inserted into a curved lower-closed arc member 124a of the second eye opening means 124. A lower arc finish member 124b may be coupled to an open end of the lower closed arc member 124a.
Each of the lower closed arc member 124a and the lower arc finish member 124b may be made of a silicone material in order to prevent skin damage and to achieve soft but tight contact.
Meanwhile, in another embodiment of the present invention, as shown in
That is, the stopper surface 132, which preferably has a smaller thickness, comes into contact with the first arm 113 or the second arm 123 when the first arm 113 and the second arm 123 are opened to a predetermined angle or more in order to prevent further rotation thereof, whereby it is possible to maintain a stable open state.
The operation of the portable device for attaching the contact lens to the eye according to the present invention, configured as described above, will be described with reference to
As shown in
Subsequently, force is applied to the index finger and the thumb in order to increase the distance between first grip hole 112a and the second grip hole 122a. As a result, the first arm 113 and the second arm 123 are opened about the pivot point 130, and the eyelid is lifted by the upper closed arc member 114a and the upper arc finish member 114b of the first eye opening means 114. At this time, an upper eyelash is lifted by the curved protrusion 114c, in the same manner as when the eyelid is lifted.
In the state in which the eye is stably open, as described above, the user attaches a contact lens to the eye while holding the contact lens in the other hand.
When attachment of the contact lens to the eye is completed, the user immediately removes the portable device 100 from their face.
In the case in which the user wishes to separate the contact lens from the eye, the user brings the portable device 100 into tight contact with the circumference of the eye in the state in which the first grip portion 112 and the second grip portion 122 are gripped using the thumb and the index finger, opens the eye, and separates the contact lens from the eye, in the same manner as in the case in which the user attaches the contact lens to the eye.
Based on the functions described above, the eye is opened by a pair of arms, which is interlocked with an ordinary operation of spreading fingers, and then the contact lens is attached to the eye, whereby it is possible to stably attach the contact lens to the eye.
In addition, the upper eyelash is lifted by the curved protrusion during opening of the eye, whereby it is possible to prevent interference with the upper eyelash and to prevent foreign matter from being introduced into the eye.
As is apparent from the above description, the portable device for attaching the contact lens to the eye according to the present invention has an effect in that the eye is opened by a pair of arms, which is interlocked with an ordinary operation of spreading fingers, and then the contact lens is attached to the eye, whereby it is possible to stably attach the contact lens to the eye.
In addition, the portable device for attaching the contact lens to the eye according to the present invention has an effect in that the upper eyelash is lifted by the curved protrusion during opening of the eye, whereby it is possible to prevent interference with the upper eyelash and to prevent foreign matter from being introduced into the eye.
Although the specific embodiments of the present invention have been described in detail above, it is obvious that the present invention can be implemented in various other embodiments without departing from the scope of the invention. Therefore, the scope of the present invention is not defined by the embodiments described above but is defined by the accompanying claims and equivalents thereto.
