摘要
Devices, systems, and methods for producing ophthalmic lens molds and molded ophthalmic lenses are described. The present devices, systems, and methods provide venting of gases produced during injection molding of ophthalmic lens molds. An optic power insert bushing is described and includes a venting system that directs gas from a first end of the bushing toward a second end of the bushing. The gas is directed between an optic power insert and an inner sidewall surface of a bushing bore in which the optic power insert is located. The bushing or bushings, and optic power inserts, can be provided as components of an ophthalmic lens mold injection system. Methods of making and using the vented bushings are also described.
