Sodium Flare Polycarbonate Glass Working Spectacles in Aluminium Wrap Frame - 62/37-16-145mm
Our Model 533 features a lightweight but durable all-aluminium frame with an ultra-sleek wrap-around design. Spring hinges assure secure fit and adjustable nose padseliminate pressure points on the nose and create a non-slip fit. ANSI Z87 approved. 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.
