In a cleanroom, the operator is typically the dominant contamination source. Anything worn near the face becomes a repeated touchpoint: adjustments, fogging, repositioning, and removal/re-don cycles all create opportunities for particle transfer and recontamination. ISO 14644 operations (OCP) frameworks explicitly include personnel management and a gowning programme as part of maintaining specified cleanliness levels. The goal is not only PPE compliance — it is controlled, repeatable handling that does not add variability to the environment.

KleenGuard™ V30 Nemesis™ VL safety eyewear (Code 20473 / Former 3013544) is a frameless, no-brow design with an IRUV Shade 5.0 lens configuration. Manufacturer specifications list ANSI Z87.1:2010, base curve 8, impact resistant protection, polycarbonate lens with nylon frame/temples, and 99.9% UVA/UVB/UVC protection. VLT is listed at 2% for this lens option.

• Low-interference profile: no-brow/frameless design helps reduce clashes with headwear and increases upward peripheral vision.
• Retention discipline: neck cord supports controlled handling (less set-down on benches, fewer drops, fewer re-dons).
• Fit control: ratcheted temples support secure positioning to reduce adjustment frequency.
• Documented baseline: ANSI Z87.1:2010 basis supports EHS documentation alignment.

Manufacturer material callout: polycarbonate lens; nylon frame and temples; Empilon nosepiece. Frame type is listed as frameless with ratcheted temples. Storage guidance is to keep eyewear cool, clean, dry, and away from direct sunlight.

Attribute	Value	Why it matters in controlled environments
Manufacturer code	20473 (Former 3013544)	Supports receiving documentation and re-order control.
Lens	IRUV Shade 5.0 (VLT 2%)	Defines filtration/visibility; verify suitability for the task (EHS-led).
Standard	ANSI Z87.1:2010	Baseline eye protection compliance reference for many industrial programs.
Base curve	8	Wrap geometry impacts coverage and fog/fit behavior.
Materials	Polycarbonate lens; nylon frame/temples; Empilon nosepiece	Compatibility and cleaning/disinfection decisions should consider material limits.
Arc flash rated	No	Do not treat this as arc-flash PPE; follow EHS requirements.

These safety glasses are not specified by the manufacturer as cleanroom-processed or sterile. In higher-grade areas, the correct approach is to treat eyewear like any other high-touch item: qualify the cleaning method, control storage, and minimize adjustments. If your operation is EU GMP sterile (Annex 1), Grade A/B entry expectations include clean, sterilized protective garments including eye coverings — which may drive you to sterilized/cleanroom-qualified goggles rather than general industrial safety glasses.

Manufacturer spec lists 12 pair/box and identifies lens type and frame/temples by code. Storage guidance is “cool, clean and dry” away from direct sunlight. For controlled environments, treat eyewear as area-dedicated where required and store in a closed container/pouch to reduce particle accumulation between uses.

• Fogging → frequent re-touching: improve fit, review mask/hood interface, and consider anti-fog eyewear where appropriate.
• Lens wiping with non-qualified materials: introduces lint/residue; use controlled wipes/solutions per SOP.
• Set-down contamination: avoid benches and pockets; use a pouch or neck cord retention.
• Using the wrong protection class: manufacturer lists “Arc Flash Rated: No”; confirm task requirements with EHS.

• 29111 (clear anti-fog, gunmetal): when fogging drives repeated adjustments and touch contamination.
• Other Nemesis VL lens tints (20470/25704/29112/20471/20472): align VLT and environment needs to the task.

Use this eyewear where you need ANSI Z87.1:2010 impact-resistant eye protection and you can control handling through your cleanroom gowning programme. If you operate under sterile manufacturing expectations (EU GMP Annex 1) or require sterilized eye coverings for ISO 4/critical suites, select qualified/sterilized eye coverings per SOP and CCS.
