    Abstract: 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.

    Abstract: The inner and outer surfaces of a toric contact lens have respectively a curved surface having a different radius of curvature wherein the central axis of the outer surface is deviated downwardly from the central axis of the inner surface. Accordingly, the position of the gravity center of the lens is lowered because the lower portion of the lens is thicker than the upper portion. Further, slab-off portions are formed in the upper and lower portions of the outer surface of the lens. The contact lens of the present invention can prevent the rotation of the lens on the cornea, provides a good feeling to a wearer, and is safe in use.
