IR absorption equivalent to shade 2.5 lens, which minimizes damage to the inner materials of the eye. Below are some frequently asked questions about Arc-Block. Accidental electrical arcing can typically happen during high-voltage switching operations, dropping of a conductive tool or other item onto current carrying lines to cause shorting and accidentally jumping, or connection of two or more current carrying wires.
Infrared radiation can cause damage to the inner materials of the eye.
Projected molten metal particles can cause burns and physical impact damage to the eye surface and inner components. It absorbs the infrared radiation to a level equal to that of a shade 2.5 lens. Finally, its' neutral gray tint provides good color recognition where needed on the job or for traffic signal recognition.
