Abstract
A contact lens insertion apparatus incorporating an illuminated target for guiding the lens into the proper position on the cornea of an eye. The lens is held in place on the apparatus by a flexible cup that maintains a vacuum between itself and the lens. A suction breaking assembly enables easy removal of the lens from the apparatus once the lens has been properly positioned on the cornea. Also included is a lower eyelid opener which not only lowers the lid for easy insertion of the lens but also provides a pivot arm enabling the user to swing the applicator up, and easily and correctly position the lens on the eye.
Claims5
An apparatus facilitating the insertion of contact lenses comprising:
- (a) a housing;
- (b) a lens holder extension tube attached to said housing and supported thereby for providing a light channel;
- (c) a flexible concave lens holder attached to and supported by said lens holder extension tube for holding a contact lens to be inserted by forming a partial vacuum between said lens and said lens holder, said lens holder including means at its center communicating with the light channel provided by said lens holder extension tube for allowing light to pass therethrough and thereby assist the operator in guiding a lens;
- (d) illuminating means contained within said housing and positioned at the end of said extension tube for providing illumination to said lens holder;
- (e) a power source for powering said illuminating means;
- (f) an eyelid opener swivelly connected to and extending from said housing for opening the lower eyelid of the eye, for steadying the apparatus against the cheekbone of the user, and for guiding the lens into the proper position on the eye;
- (g) a suction breaker operationally connected to said lens holder for allowing air to enter between said lens and said lens holder in order to break the suction therebetween and thereby easily remove the apparatus from the lens once the lens has been positioned on the eye;
- (h) a suction breaker switch positioned on said housing for activating said suction breaker and for turning off said illuminating means;
- (i) a light switch operationally connected to said illuminating means and positioned at the end of said housing opposite said lens holder for activating said illuminating means;
- and
- (j) a thumb holder attached to said housing in a position approximately 180.degree. displaced from said suction breaker switch for facilitating the gripping of said apparatus by an individual and for facilitating the proper alignment of the individual's fingers upon said apparatus for easy operation thereof.
