Abstract
Fluidic adaptive lens devices containing impermeable elastomer membrane, and systems employing such lens devices, along with methods of fabricating such lens devices, are disclosed. In the embodiments, processes and techniques of creating transparent, impermeable elastomer membranes are disclosed. The membranes thus produced display no or extremely slow permeation for at least one fluid suitable for the fluidic adaptive lenses.
