摘要： It is an object of the present invention to provide a contact lens solution that imparts stable hydrophilicity even to a surface of a contact lens having strong water repellency. There was prepared a contact lens solution comprising a copolymer of N-p-vinylbenzyl-D-lactonamide and at least one monomer copolymerizable therewith. The copolymer is present in the solution in an amount of 0.0001 to 5 w/v %.

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 device of the present invention includes: apparatus for photographing an anterior eye segment of a subject; a first display device for displaying an image of the anterior eye segment; a device for processing the displayed image to detect the relative positions of a pupil and a contact lens, respectively; a calculating apparatus for obtaining the relationship of relative positions between them by calculating; and a second display device for displaying the obtained relationship of the relative positions. The described arrangement is particularly useful for inspecting a condition for the putting on of the contact lens by measuring the relationship of the relative positions between the contact lens at the time of being put on and the pupil of the concerned eye segment.
