摘要： A vacuum lamination apparatus for performing a vacuum lamination process on a lamination material includes a base plate having two opposing sides for placing the lamination material; and evacuation members having an approximately triangular cross-section and fixed hermetically to the base plate at the two opposing sides. Each of the evacuation members has an evacuation port with a constant distance relative to the base plate. The vacuum lamination apparatus also includes end plates fixed hermetically to ends of each of the evacuation member, and a cover sheet placed on the base plate for covering the lamination material and the evacuation members to form a lamination space for performing the vacuum lamination process.

摘要： A method of manufacturing a contact lens having a mark is provided, wherein the contact lens is provided with a mark at the same time as the polymerization of the contact lens in the mold. The coloring composition, for the mark includes a medium which includes at least one monomer component of the monomer mixture used to form the polymer of the contact lens; and a predetermined dyestuff. A concave molding surface is roughened by forming a multiplicity of minute recesses by sputtering to define a marker portion, and the coloring composition is attached to the roughened concave molding surface. The coloring composition is then prepolymerized in the marker position before the monomer mixture of the contact lens material is introduced into and polymerized in the mold.
