device for the study of soft contact lenses.

摘要

A soft contact lens measuring device. A cylindrical lens support defines a cavity and pedestal for immersing a soft contact lens in a saline solution. A piston engages the support and can be operated by the user to force air in controlled amounts through a narrow passageway extending up through the pedestal 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 focusing a radiuscope to allow lens dimensions to be determined.
