| 摘要 |
<p>This invention relates to a method of manufacturing a contact lens which has a first section formed from a first material and a second section formed from a second material. The method includes the use of a casting mould (1) which has an end wall (3) that is inwardly displaced into the space defined within the mould to define a receptive well (S, T) into which material can be cast to be cured/polymerised to form a lens button (B). The method further includes: casting a first monomer material into the receptive well of the casting mould and polymerising/curing the monomer material; and machining the article formed by the above casting into a contact lens (CL) wherein the first monomer material includes a polymerisable material which has a penetrating-like action with respect to the material from which the casting mould is formed that acts to bond the mould and the cured/polymerised material together.</p> |
