The "Z87+" marking identifies safety eyewear that meets the high-impact performance requirements defined in ANSI/ISEA Z87.1. Compared with basic Z87 markings, Z87+ products undergo more demanding impact testing and are intended for environments where workers face higher risks from flying objects and mechanical hazards. Additional markings may also indicate protection against dust, splash, anti-fog performance, or optical filters depending on the product design. Understanding these markings helps buyers select appropriate eye protection for specific workplace hazards.

ANSI Z87.1 certified safety glasses are evaluated through laboratory testing covering impact resistance, optical quality, lens retention, frame durability, product marking, and minimum coverage requirements. Depending on the intended application, additional testing may be required for splash protection, dust protection, anti-fog performance, or specific optical filters. These evaluations verify that certified eyewear provides reliable protection under occupational conditions while maintaining clear vision and consistent performance throughout normal use.

ANSI Z87.1 certified safety glasses are widely used throughout the United States in construction, manufacturing, logistics, warehousing, metal fabrication, woodworking, utilities, laboratories, maintenance, and many other industrial sectors. Employers typically select certified eye protection based on workplace hazard assessments and OSHA safety requirements. Certified eyewear provides confidence that products have been tested for occupational use and are suitable for environments involving impact hazards, airborne particles, and other common industrial risks.

Yes. ANSI Z87.1 establishes minimum safety and performance requirements but does not prevent manufacturers from incorporating additional technologies that improve comfort, durability, or visibility. Features such as wash-resistant anti-fog coatings, scratch-resistant lenses, ergonomic comfort systems, and wraparound side protection can all be integrated while maintaining compliance with ANSI performance requirements. Combining certification with advanced technologies helps workers achieve clearer vision, longer product life, and improved wearing comfort in demanding industrial environments.
