Lightweight, clip-on/flip-up polycarbonate spectacles are excellent for filtering UV and IR rays. They will fit almost any frame style.
Lens Options
Brightness reduction from a shade 3 up to a shade 8 welder's tint. Can be used over other glasses to provide additional protection, however cannot be used as the sole lenses for flameworking as these do not filter out sodium flare. Shade 6 and higher is often used for quartz flameworking.
