Abstract: A lens includes a lens portion; a multilayer anti-reflective (AR) coating layer, including either one or both of a low refractive index layer and a high refractive index layer, disposed on one surface of the lens portion; and a water-repellent layer, including a water repellent, disposed on one surface of the multilayer AR coating layer. Either one or both of the low refractive index layer and the high refractive index layer are formed of a nitride-based material with a band gap greater than 3.1 eV.
