Protective Screens and Filters for IR Protection
The best known adverse effects of infrared (IR) radiation are dry eyes and burn or scalding of the skin as acute effects, and cataract as a long term effect. This is discussed in greater detail in other lectures. Severe acute effects of IR radiation are only seldom seen in the industrial environment but one often meets situations with dry, irritated eyes and situations of obvious discomfortable viewing conditions. Most of these situations can be alleviated quite easily. Of greatest concern is the possibility of accelerating cataract formation in the eye’s lens because this may call for an early surgical operation.
