  The present invention provides an aromatic polyester which is substantially free from the occurrence of coloration and retains significantly high transparency even after being thermally processed at high temperature and which has high flowability. The aromatic polyester contains a polyhydric phenol residue and a residue of any one of aromatic polycarboxylic acid, halide thereof, and anhydride thereof, and terminals of the aromatic polyester have a structure represented by the formula -C(O)-R. The aromatic polyester has an end-capping rate of 90% or higher and a weight average molecular weight (Mw) ranging from 3,000 to 1,000,000.

  A contact lens case having antimicrobial characteristics composed of a polymeric material having a plurality of amorphous zones. An antimicrobial agent is incorporated into said amorphous zones of the polymeric material of said body. The antimicrobial agent exhibits controlled migration through the amorphous zones of the polymeric material of said body. In this manner, the surface of the lens case is consistently saturated with an antimicrobial agent.
