Abstract

A patented new injection-molding technology, which already has been commercially licensed nonexclusively to leading Rx polycarbonate lensmakers and is now under development with leading contact lensmakers, gives very high moldpacking pressures (needed for maximum microsurface replication) without high birefringence (minimized by reducing constrictiveness during fill), even with high viscosity optical thermoplastic polymers.
