    • 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.
    • 一种制造眼透镜的方法,包括以下步骤:(a)制备提供眼透镜的透镜毛坯,所述透镜毛坯具有凹后表面和凸前表面,所述前表面的至少一部分是锥形的 给出锥形表面; (b)通过在透镜毛坯的凹面后面进行切割操作来形成眼镜片的后曲面,同时将镜片毛坯支撑在背面切割装置的主轴上,使得透镜的锥形表面 空白在施加到透镜毛坯的负压下拉到主轴的锥形保持表面上,锥形保持表面遵循透镜毛坯的锥形表面的轮廓; 以及(c)通过对其后表面已经被切割以形成后曲面的透镜毛坯的前表面进行切割操作来形成眼镜片的前曲面,而镜片毛坯被支撑在 前表面切割装置,使得透镜毛坯的后曲面在施加到透镜毛坯的负压下被拉到前表面切割装置的主轴的保持表面上。

    • 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.
    • 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。
