摘要： The present invention was developed to improve wearing conditions of a soft contact lens while improving production efficiency of the soft contact lens and assuring an enhanced optical effect offered by the lens. The present soft contact lens has a back surface, a front surface and a connecting surface. The back surface of the lens is constituted by: a central portion formed by an ellipsoidal surface with an eccentricity in the range of 0.2-0.7 and a vertex radius of curvature in the range of 5.00-10.00 mm; an intermediate portion which is located at the periphery of the central portion so as to surround the central portion and is formed by another ellipsoidal surface with an eccentricity in the range of 0.2-0.7, at least one of the eccentricity and a vertex radius of curvature of the ellipsoidal surface of the intermediate portion being different from that of the ellipsoidal surface of the central portion; and a marginal portion which is located around the periphery of the intermediate portion and formed so that the marginal portion is spaced away from the cornea such that an axial clearance between the cornea and the back surface of the contact lens increases with an increase in a distance of the marginal portion from the intermediate portion in a radially outward direction. The central, intermediate and marginal portions are continuously contiguous to each other to provide the back surface of the lens.

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： 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.
