Abstract: Disclosed are optical elements and the methods of producing the same. The optical element contains two or more near infrared absorbers mixed in an optical substrate, and one or more functional film disposed on the optical substrate. The method of producing the optical element comprises mixing two near infrared absorbers with different near infrared wavelengths absorption ranges and residual colors with a precursor of an optical substrate. The mixture is subsequently processed to produce an optical element that has broad near infrared wavelength absorption range, a high near infrared absorption level, and/or homogeneous color distribution.

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.
