ABSTRACT:
The disclosure is directed to a device for inserting and removing contact lenses formed from an elongated body of resilient material having opposite terminal end portions and a central longitudinal axis, a first of the end portions having a relatively shallow concavely outwardly opening locating surface upon which a contact lens will be retained incident to inserting the lens upon an eye, a second of the terminal end portions being of a frusto-conical configuration on a narrow end of which is a suction cup having a concavely outwardly opening locating surface upon which a contact lens will be retained upon removing the lens from an eye, the concave surfaces having generally parallel radii of generation which are normal to a common plane defining a generally 45 degree angle with the central axis, and the latter relationship allows complete visibility during insertion or removal of contact lenses, particularly when a mirror is being utilized and more particularly when the user has very poor or limited vision.
