Quartz requires much higher torch temperatures than soft glass or borosilicate, producing intense white-hot glare and dangerous levels of infrared (IR) heat that standard sodium flare glasses cannot safely filter.

Shade level depends on torch size and gas mixture. Typically, quartzworking requires Shade 3 to Shade 5 for medium torches, and Shade 6 to Shade 8+ for large, oxygen-rich torches or lathe operations.

Yes. High-grade quartzworking lenses are specifically formulated with dense IR absorbers to block heat radiation, preventing eye dryness, fatigue, and long-term lens damage.

Yes. VS Eyewear quartzworking glasses are built into impact-resistant safety frames that meet or exceed ANSI Z87.1 industrial safety standards.

Yes. We can craft custom prescription lenses in designated quartzworking shade materials, including single-vision and bifocal options.

Because quartzworking lenses use darker protective shades, they significantly dim surrounding room light to keep the white-hot melt safe to look at. Adequate studio lighting is recommended for your surrounding workspace.

Depending on the specific shade and filter requirements, quartzworking lenses are crafted from high-density optical glass or specialized IR-absorbing polycarbonate.

Yes. The heavy UV, IR, and visible glare filtering in quartzworking optics makes them well-suited for high-temperature gas, hydrogen, and plasma applications.

Look for safety frames with integrated ventilation ports or apply an anti-fog coating to the inner lens surface to maintain clear vision during intense hot shop work.

Store them in a hard protective case when not in use, and clean the lenses regularly with warm water and a clean microfiber cloth to prevent grit from scratching the filter coatings.
