shuku>i miss you的意思摘要：soft contact lens are made by polymerizing a substantially anhydrous polymerization mixture containing a polymerizable acrylic or methacrylic monomer, and a water displaceable ester of boric acid and a compound containing 3 or more hydroxyl groups so as to form a hydrophilic polymer containing at least 30% of said boric acid ester. In a preferred embodiment, the polymerization is effected in a mould cavity where the contact between a sharp circular edge in one mould part and a spherial surface in the other mould part defines the edge of the lens and the distance between the two mould surfaces outside the sharp edge increas in all radial directions away from the center.
