Poly Sodium Flare Glass Working Glasses in Plastic Safety Frame - 50mm Eye Size
This Sodium Flare polycarbonate material is very efficient in filtering sodium flare in addition to providing excellent ultraviolet protection. The material has very similar characteristics to our standard Phillips 202 (Didymium) glass material. 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 glass working where Infrared protection is needed. This filter is more for soft glass usage and clear borosilicate work.
