#CMT# #/CMT# The lens has a radial cross-section comprising an edge area that is formed on an inner surface (1) of the lens and provided between a turning point (6) and an outer edge, where a convex contour is formed in the outer edge with a radius of 0.1-10 mm. An outer peripheral part of the lens exhibits an irregularity such that a mean square deviation of the outer peripheral part is associated with a circular line mean square deviation of about 5000 micro meter square, where width of the edge area of the lens lies within a range of 0.01-0.1 mm. The lens is treated with a polar liquid. #CMT# : #/CMT# An independent claim is also included for a method for manufacturing a silicone contact lens. #CMT#USE : #/CMT# Silicone contact lens i.e. poly dimethylsiloxane contact lens (claimed), for use on a cornea of an eye. #CMT#ADVANTAGE : #/CMT# The radial cross-section comprises the edge area that is formed on the inner surface of the lens and is provided between the turning point and the outer edge, where the convex contour is formed in the outer edge with the radius of 0.1-10 mm, thus enabling the lens to slide on tear liquid film in an easy manner, and hence ensuring better or outstanding comfort to a user. The lens is manufactured without formation of a cut edge, thus avoiding creation of disturbance feeling to the user. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an enlarged schematic sectional view of an edge area of a contact lens. 1 : Inner surface of contact lens 2 : Outer surface of contact lens 4 : Transition region 5 : Curved region 6 : Turning point. |
