VetroSafe(r) Guardian OTG Glassblowing Safety Glasses Shade 3 (Didymium-Alternative Polycarbonate Lens) for Lampworking, Flameworking, Glassblowing

Features

• UPGRADED FRAME MATERIAL: Frame material upgraded to Grilamid TR-90 for improved resilience against cracks, heat and solvent exposure.
• DIDYMIUM-ALTERNATIVE POLYCARBONATE LENS: Traditional didymium glass lenses are heavy and do not have sufficient protection against infrared and blue-light without extra welding shade lenses, adding weight and bulk. VetroSafe’s VSF-3.0 Shade 3 lens provides equivalent functionality to didymium lenses with improved impact resistance, and lower weight thanks to its optical-grade polycarbonate base.
• FOR SOFT AND HARD GLASS FLAMEWORKING: Shade 3.0 lens is suitable for soft glass lampworking and the majority of borosilicate (boro) flameworking. Shade 3.0 lens blocks 100% of UV light and 95% of near-IR infrared light.
• ANSI Z87.1 STANDARD: Be prepared for the unexpected with high-impact lenses and frame – full-coverage frame protects the eyes from impact, foreign objects and radiation sources including lateral protection.
• OPTICAL-GRADE COATINGS: Lenses include ophthalmic-grade anti-scratch coating plus optical-grade backside anti-reflection coating to improve clarity, and super hydrophobic top-coating that resists smudging and makes the lenses easy to clean.
• BALANCED COLOR VISION: Proprietary lens design and blue-flash mirror coating are designed to provide optimally balanced color vision and improved brightness.
