Soft contact lens analyzer.

摘要

A soft contact lens measuring device comprises a cylindrical lens support (10) defining a cavity (12) and pedestal (16) for immersing a soft contact lens in a saline solution. A piston (40) engages the support and can be operated by the user to force air in controlled amounts through a narrow passageway (22) extending up through the pedestal (16) to the saline solution. A bubble forms and rises until it is trapped by the lens. The interface between the bubble and the lens makes a convenient surface for focussing a radiuscope to allow lens dimensions to be determined.
