For best eye protection against optical radiations: our new lens IR infrared. Optical radiation damages on the eyes are due to their wavelength and power. Radiations are ultraviolet UV light (length: 100-380 nm), visible light (length: 380-780 nm) and infrared IR-A light (length 780 m-1 mm). IR lens totally stops the absorption of UV lights (UV-A, UVB, UV-C), cause of several diseases (cataract, retina degeneration, and photokeratoconjunctivitis). It stops blue light absorption (380-550 nm) one of the cause of photoretinitis. It stops the absorption of infrared IR-A rays, which cause heat damage on eyes, cataracts, damages on retina and cornea and keratocongiuntivitis. IR lens guarantees a clear vision and best depth; protection cat. 2.
