    摘要： 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.

    摘要翻译： 本发明涉及用于插入和移除由具有相对的末端部分和中心纵向轴线的弹性材料的细长体形成的隐形眼镜的装置，第一端部具有相对较浅的凹入向外的开口定位表面， 接触透镜将被保持入射以将透镜插入到眼睛上，第二终端部分具有截头圆锥形构造，其窄端是具有凹入向外打开的定位表面的吸盘，接触透镜 在从眼睛移除透镜时将被保留，凹面具有大致平行的生成半径，其垂直于与中心轴线大致成45度角的公共平面，并且后者的关系允许在插入或移除透镜期间完全可见 隐形眼镜，特别是当使用镜子时更特别是当使用者具有非常p时 oor或有限的视力。

    摘要： An elongated resilient cylindrical body of small diameter has at its forward end a contact lens holding suction cup. A small diameter axial duct extends entirely through the body. The duct is open at its forward end at the central portion of the cup and at its opposite end at the distal end of the body. The body has a tapered portion which is of progressively decreasing diameter from a location near the distal end of the body to the distal end. The distal end of the body thus presents rearwardly a relatively small annular contact sealing area surrounding the rear end of the duct. The tapered portion is related to the diameters of the body and duct, and to the resilience of the body, so that, with the body held between the thumb and one finger of the user's hand, the tapered portion can be squeezed lightly radially therebetween, while another finger of the hand covers and closes the rear end of the duct, thereby compressing the tapered portion to a degree sufficient to reduce the volumetric capacity of the duct and thereby retain to a greater degree the holding force of the cup.

    摘要翻译： 细长的小直径的弹性圆柱体在其前端具有保持吸盘的隐形眼镜。 小直径的轴向管道完全延伸穿过身体。 导管在其前端在杯的中心部分处敞开，并且在其相对端处在主体的远端处。 主体具有从身体的远端附近的位置到远端的直径逐渐减小的锥形部分。 因此，身体的远端向后呈现围绕管道后端的相对小的环形接触密封区域。 锥形部分与身体和管道的直径以及身体的弹性相关，使得当身体保持在拇指和使用者的手的一个手指之间时，锥形部分可以在其间径向轻轻挤压， 而手的另一个手指覆盖并关闭管道的后端，从而将锥形部分压缩到足以减小管道的容积的程度，从而更大程度上保持了杯的保持力。

    摘要： A device having an elongated resilient body in the form of an open top trough with upwardly divergent side walls and open at the ends. One end of the body has integral lens gripping pads arranged one on each side wall. The pads are spaced from each other laterally of the body and are movable toward each other by flexure of the side walls. The pads are shaped so that, when they are engaged with a soft contact lens which is installed on the cornea of a human eye and then moved toward each other, they first flex the lens so that its posterior face disconforms to the cornea and air can enter therebeneath and release the adhesion of the lens to the cornea, and then support the lens by the device so that it can be removed from the eye by manipulation of the device. The opposite end of the body is arranged to support the lens in undistorted condition for insertion into the eye by manipulation of the device.
