Clip-on's & Fitovers

This polycarbonate is very efficient in filtering sodium flare in addition to providing good ultraviolet protection in our Clip-on’s & Fitovers.  It is very comfortable for viewing under high ambient light conditions such as when working with glowing heat sources for a duration of time. Also, although it has a relatively low luminous transmission of 38%, it is not recommended for glassworking where Infrared protection is needed.  This filter is more for soft glass usage.
