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

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

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. Get Safe, Get VetroSafe - Designed from the ground up to include every safety feature as standard: our modern didymium-alternative high-impact polycarbonate lens features OD5+ sodium flare blocking, 100% UV blocking, UV420 blue-light blocking and ANSI Shade 3.0 >95% IR blocking.
