    摘要： A method of producing an ocular lens, comprising the steps of: (a) preparing a lens blank which gives an ocular lens, the lens blank having a concave back surface and a convex front surface, at least a portion of the front surface being tapered to give a tapered surface; (b) forming a back curved surface of the ocular lens by effecting a cutting operation on the concave back surface of the lens blank, while the lens blank is supported on a spindle of a back surface cutting device such that the tapered surface of the lens blank is drawn onto a tapered holding surface of the spindle under a negative pressure applied to the lens blank, the tapered holding surface following a profile of the tapered surface of the lens blank; and (c) forming a front curved surface of the ocular lens by effecting a cutting operation on the front surface of the lens blank whose back surface has been cut to form the back curved surface, while the lens blank is supported on a spindle of a front surface cutting device such that the back curved surface of the lens blank is drawn onto a holding surface of the spindle of the front surface cutting device under a negative pressure applied to the lens blank.

    摘要： A marking apparatus for providing desired marks such as characters, symbols, graphics, etc. on surfaces of contact lenses in a standardized manner. The marking apparatus includes a main shaft rotatable about an axis and a screen support mounted on the main shaft so as to be rotated therewith. The screen support has a plurality of marking holes provided at equal intervals around a circumference thereof and a screen is stretched across the support. The screen includes patterns associated with the desired mark which are provided in correspondence with the marking holes. A bracket is mounted on the main shaft under the screen support so as to be rotated with the main shaft. A plurality of supporters are supported by the bracket and function to individually support lens beds on which the lenses are respectively disposed. The supporters are movable up and down between a position where the respective contact lenses mounted on the lens beds are brought into contact with corresponding patterns of the screen and a displaced position where the contact lenses can be mounted on or removed from the supporters. Finally, an injector placed above the screen support applies a print solution to the screen stretched in the corresponding one of the marking holes of the screen support.

    摘要翻译： 一种用于以标准化方式在隐形眼镜的表面上提供诸如字符，符号，图形等所需标记的标记装置。 标记装置包括可绕轴线旋转的主轴和安装在主轴上以与其一起旋转的屏幕支撑。 屏幕支撑件具有围绕其圆周以等间隔设置的多个标记孔，并且屏幕跨过支撑件延伸。 屏幕包括与标记孔相对应地设置的与所需标记相关联的图案。 支架安装在主轴下面的屏幕支撑件上，以便与主轴一起旋转。 多个支撑体由支架支撑并且用于分别支撑透镜分别设置在其上的透镜床。 支持者可以在安装在透镜床上的各个隐形眼镜与屏幕的相应图案接触的位置和可以将隐形眼镜安装在支撑者上或从支持者移除的位移位置之间上下移动。 最后，放置在屏幕支架上方的注射器将印刷溶液施加到在屏幕支撑体的相应的一个标记孔中拉伸的屏幕上。

    摘要： A jig adapted to hold a contact lens material having a concave surface, for holding the contact lens material, including a protruding portion which has a top end having as an outer surface thereof a convex surface. This convex surface of the jig is bonded to the concave surface of the contact lens material. The protruding portion has a recess which extends from an inner surface of the top end toward a bottom end of the protruding portion. The recess is defined by an inner surface which includes a first portion that corresponds to the convex surface of the top end of the protruding portion. At least the first portion of the inner surface is toughened with a light-scattering texture. A method of holding the contact lens material while the contact lens material is processed into a contact lens is disclosed.

    摘要： A contact lens cleaning device comprising a ball, a vessel formed with a recessed chamber for housing the lens and the ball, and a vibrator for vibrating the vessel. The chamber has a bottom concave surface so curved that the lens is mounted in face-to-face contact thereon. After the lens is sandwiched between the bottom concave surface of the chamber, the ball is cleaned when the vessel is vibrated by the vibrator.
