These green lens safety glasses have lenses that are a soft green color. The spectral response of this material shows excellent ultraviolet and infrared protection. The visible light transmission in our glassblowing eyewear is adequate for good visibility under most shop working conditions where illumination is somewhat limited.
The filter DOES NOT provide sodium flare protection. Suggested uses are offhand work, allowing for comfortable viewing of glory holes, fire buckets, gathering, enameling, and general kiln work.
