Ultraviolet-hardenable adhesive and bonding method employing same

A process of producing a non-water swellable, ophthalmic lens, comprising the steps of:

• preparing an ultraviolet-hardenable adhesive comprising at least one photopolymerizing monomer and at least one photoinitiator, said at least one photopolymerizing monomer being selected from the group consisting of acrylates or methacrylates represented by following general formulas (I) and (II):
• ##STR16## ,wherein R.sub.1 is hydrogen or methyl,
• R.sub.2 is hydrogen or methyl,
• R.sub.3 is hydrogen or methyl,
• m is a positive integer from 2 to 10, and
• n is a positive integer from 1 to 5;
• bonding a non-water swellable, ophthalmic-lens blank to a support member with said ultraviolet-hardenable adhesive;
• exposing the bonded ophthalmic-lens blank and support member to ultraviolet rays so as to harden said adhesive;
• subjecting said ophthalmic-lens blank to working and/or treatment so as to form the lens blank into a desired non-water swellable ophthalmic lens;
• and
• separating the ophthalmic lens from said support member.
