Sodium Flare Polycarbonate Glass Working Spectacles in Viper Wrap Frame - 59/35-18-142mm
Phillips Safety's New Model 703 with sharp corners and stylish angles make the 703 a great addition to anyone's hot glassworking eyewear collection. Along with the added protection of an ANSI Z87 safety rating, this gloss black frame comes with perforated rubber nosepieces so it doesn't slip off your face and it also offers increased breathability. The lenses are Polycarbonate Sodium Flare with an anti-scratch coating. Excellent for Soft Glass Working application.
This polycarbonate is very efficient in filtering sodium flare in addition to providing good ultraviolet protection. 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.
