Abstract
Disclosed is a user wearable optical article including an optical substrate and an interferential coating. The interferential coating may be disposed the substrate and may be configured to selectively reflect light of at least one range of wavelengths of an incident light in the near infrared light spectrum. A peak reflectance measured at a substantially normal to the optical article may be at least 70%. An eyewear including an optical article and a method for producing an optical article are also disclosed. The method may include providing the optical substrate and providing the interferential coating disposed on the optical substrate. The interferential coating may selectively reflect light of at least one range of wavelengths of an incident light in the near infrared light spectrum. A peak reflectance may be at least 70% and the interferential coating has a mean reflectance of less than 1.5% in a visible light range.
