Abstract:
Optical polymeric sheets with specific ranges of optical retardation, elastic modulus, and Shore A hardness were used to construct flexible polar patches. The polar patches conform to non-polarizing lenses of various diopter bases and provide polarizing efficiency that is comparable to regular polarizing lenses.
