Why eyewear matters in cleanrooms (beyond “eye safety”)
In controlled environments, eyewear is a dual-purpose control: it protects the operator’s eyes and it helps reduce workflow disruptions that create contamination risk.
The most common cleanroom failure mode for eyewear is not “breakage”—it is repeated adjusting, lifting, or swapping due to poor fit or fogging.
The Nemesis Small platform is designed to fit smaller heads without constant repositioning, supporting steadier wear behavior across a shift.
What this product is used for
- Impact-rated eye protection for production, maintenance, and material-handling work where ANSI Z87.1+ eyewear is required.
- Gowning anterooms and controlled environments where eye protection is part of site EHS policy.
- Operators who need a smaller frame geometry to reduce slippage and fit-driven “touch events.”
- Smoke lens preference for bright indoor/outdoor transitions and glare-prone work zones.
Why customers consider this product
- Small fit improves compliance: fewer comfort complaints and fewer adjustments during work.
- Wraparound coverage: base-8 curve extends peripheral protection.
- UV protection: polycarbonate lens platform supports UVA/UVB/UVC filtering.
- Stability features: FLEX-DRY* temples help reduce slippage in warm/humid work.
- Continuity and support: SOSCleanroom is expanding KleenGuard/Ansell availability with selection guidance aligned to controlled-environment behaviors.
Materials, build, and wear platform
Nemesis Small safety glasses use a polycarbonate lens platform with a wraparound frame geometry designed for extended peripheral protection and a stable face fit.
The smoke lens option is commonly selected for bright environments and outdoor transitions.
Cleanroom relevance: the best eyewear is the eyewear operators actually keep on. A stable, comfortable fit reduces repeated touch/adjust behaviors that can undermine both safety and contamination-control discipline.

Performance and cleanliness considerations (controlled environments)
In cleanrooms, eyewear problems almost always show up as behavior problems: fogging drives lifting; poor fit drives repositioning; and scratchy lenses drive wiping.
Each of those actions increases face/hood contact events and can disrupt aseptic or controlled workflow discipline.
If operators routinely wear masks or hoods, consider whether an anti-fog eyewear option is warranted. If a coating change is made, validate the cleaning/disinfection method to avoid damaging the coating or creating haze.
Packaging, traceability, and country of origin
This item is supplied as a case of 12 glasses and is listed with country of origin: Taiwan on the SOSCleanroom product page.
If your program tracks PPE by lot or shipment, retain the receiving record with SKU/UPC identifiers.
For contamination-control programs, packaging discipline matters: do not stage opened eyewear cartons on uncontrolled surfaces and then carry them into cleaner zones without a defined handling method.
Best-practice use (donning guidance — ISO first, then Annex 1 context)
Technique guidance: reduce “touch events” during gowning
- ISO 14644-5 alignment: Treat eyewear as part of your gowning program inside the Operations Control Programme (OCP). Define where eyewear is donned, how it is cleaned, and how it is stored to prevent recontamination.
- Don before higher-grade entry when possible: Perform fit checks and comfort adjustments in the lower-grade area so you are not manipulating eyewear after gowning.
- Handle by the temples: Avoid touching lenses or face-contact points. Once gloved and gowned, re-handling eyewear is a common contamination pathway.
- Cleaning method control: Use only site-approved cleaning/disinfection compatible with polycarbonate (and any coatings). Avoid improvised solvents that can craze lenses or damage coatings.
- Storage discipline: Store in a clean pouch or designated rack. Do not hang eyewear on hoods, masks, or uncontrolled hooks.
European Annex 1 context (sterile manufacturing): In Grade A/B environments, Annex 1 describes sterile eye coverings (e.g., goggles) as part of the gowning set, with emphasis on gowning qualification, procedure compliance, and garment integrity checks.
If you are operating under Annex 1 expectations, evaluate whether safety glasses are sufficient for the specific area, or whether sealed/sterile goggles are required by your contamination control strategy.
Common failure modes (and how to prevent them)
- Fogging drives lifting: move to anti-fog options or adjust mask/hood interface to reduce warm air flow into lenses.
- Poor fit drives constant repositioning: standardize Small fit where needed rather than forcing a universal fit.
- Lens wiping scratches lenses: define a cleaning method and a lens-safe wipe approach; avoid dry wiping.
- Uncontrolled storage: stop “set it anywhere” behavior; designate storage to prevent recontamination.
- Coating mismatch to SOP: if coating type matters, verify at receiving and document to the program requirement.
Closest competitors (selection logic)
Closest alternatives are other small-size, ANSI Z87.1+ wraparound safety glasses in smoke or indoor/outdoor lenses. In controlled environments, compare fit stability, fog behavior, and cleaning compatibility—not only unit cost.
- Small-fit anti-fog safety glasses: when masks/hoods are driving fogging-related adjustments.
- Sealed goggles: when splash, chemical, or higher-grade contamination controls require a more enclosed eye barrier.
- Sterile goggles/eye coverings: when Annex 1 / sterile-grade gowning requires sterile eye coverings as part of the set.
Critical environment fit for this product
Nemesis Small (38476) is a strong fit when your operation needs impact-rated eyewear and you have a meaningful population of smaller head sizes where universal frames reduce compliance.
For sterile manufacturing grades governed by Annex 1 expectations, confirm whether your CCS/gowning SOP requires sterile or sealed eye coverings in the specific area.
SOSCleanroom supports these decisions with Ansell/KleenGuard continuity and practical, behavior-based selection guidance.
SOSCleanroom note about SOPs
The Technical Vault is written to help customers make informed contamination-control decisions and improve day-to-day handling technique.
It is not your facility’s Standard Operating Procedure (SOP), batch record, or validation protocol.
Customers are responsible for establishing, training, and enforcing SOPs that fit their specific risks, products, equipment, cleanroom classification, and regulatory obligations.
Always confirm material compatibility, cleanliness suitability, and acceptance criteria using your internal quality system and documented methods.
If you adapt any technique guidance from this entry, treat it as a starting template. Your team should review and approve the final method, then qualify it for your specific processes and risk profile.
