ABSTRACT:
The invention relates to a device for handling a plastic lens to remove the same from an eye of a user. The device is of a tweezer or pincer type comprising two arms that are joined at one end to form a unit with the arms at an acute angle and having a common plane in which the arms can be moved one toward the other. Each arm is provided at its free end with an extension angularly disposed relative to its respective arm and to the plane of movement. A soft holder of generally ellipsoidal shape and having axially arranged peripheral slots is mounted on each extension. The angular relationship between the arms and the extensions and holders permits the device to be accurately aligned with the lens in place over the eye without obstructing the user's vision as the device is moved toward the eye for engagement of the lens within its peripheral edge by the holders. The contact lens is positively engaged within its peripheral edge by the slots in each holder and is folded as the arms are moved into a position of minimum seraration in which position the plastic lens has been effectively released from the eye for complete removal by the device.
