New Model OTG Fitover Frame. Comfortable unifit nylon frame, Fitover design, Adjustable temple bars that is lightweight and durable, and Polycarbonate Sodium Flare lenses with a 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.
