Infrared Radiation

I was asked during my class at WGW about infrared radiation eye protection for kiln workers. I originally said that didymium was adequate. Marty Kremer point out that this was incorrect (is there anything this guy does NOT know?), so I did some more research on this topic:
The infrared (IR) spectrum wavelengths ranges from 750 nanometers (nm) to about 10,000 nm. Any hot body emits infrared radiation. IR does not penetrate below the superficial layers of the skin. Radiation in the near infrared region (IR-A 750 nm – 1500 nm) can cause acute skin burn. The shorter wave lengths are also absorbed in the iris and cornea of the eye, from which heat is transferred to the lens. Excessive exposure of the eyes to infrared radiation from furnaces and other hot bodies had traditionally been thought to produce “Glass Blower’s Cataractâ€
