IR Infrared Lenses

For maximum protection of the eye from optical radiation, the infrared IR technical lens is available. The harmful effects of optical radiation on the eye are determined by their different length and the consequent energy level. Radiation is divided into ultraviolet UV radiation (length: 100-380 nm), visible radiation (length 380-780 nm) and IR-A infrared radiation (780 nm-1 mm). The IR lens totally blocks the absorption of ultraviolet rays (UV-A, UV-B, UV-C), responsible for diseases such as cataracts, retinal degeneration and photokeratoconjunctivitis. It also blocks the absorption of blue light (380-550 nm), responsible for photoretinitis. It blocks the absorption of infrared rays (IR-A), which cause thermal damage and induce cataracts, as well as being responsible for corneal and retinal damage, it also protects against keratoconjunctivitis sicca. The IR lens ensures clear vision and maximum depth; Cat. 2 of protection.
