What this product is (manufacturer identity)
Manufacturer product information lists code 25676 (former code 3000354) as a
clear-lens, black-frame Nemesis variant with
%VLT 87–93 and packaging of 1 each/bag; 12 bags/case.
The Nemesis platform is described by the manufacturer as wraparound eyewear with a listed base curve of 8.25,
a Flex-Dry nose piece intended to channel sweat and reduce slippage, and flexible temples designed for long-wear comfort.
A neck cord is included for retention and quick availability.
Cleanroom / controlled-environment fit (scope discipline)
These are safety glasses intended for impact-rated eye protection in general facility and industrial contexts.
In controlled environments, confirm whether your gowning SOP calls for open safety glasses versus sealed goggles.
In higher-grade sterile manufacturing contexts (e.g., EU GMP Annex 1 Grade A/B), programs commonly require sterile face coverings and sterile eye coverings (goggles) as part of a fully enclosed gowning system.
Donning (gowning) guidance: ISO first, then Annex 1 overlay
ISO operations mindset: control people + behavior to control contamination
ISO cleanroom operations guidance emphasizes an operations control programme that includes personnel practices, entry/exit controls, training, and a defined gowning programme.
Practically, eyewear is a “behavior control” tool: stable fit reduces face touching and repeated adjustments that transfer contamination to gloves and garments.
- Stage eyewear before gowning begins: avoid carrying eyewear through uncontrolled areas after gowning starts.
- Don by temples only: treat the lens + face interface as “no touch.”
- Fit check once, then hands off: repeated adjustments are a common particle-transfer event.
- Cleaning method qualification: validate wipe-down chemistry for polycarbonate to avoid haze and residue.
European Annex 1 overlay (sterile manufacturing):
Annex 1 expectations for Grade A/B emphasize a fully enclosed gowning system and commonly include sterile face coverings and sterile eye coverings (goggles).
If your operation is Annex 1 governed, treat eyewear selection as a compliance decision: confirm sealed/sterile goggle requirements rather than using open safety glasses in critical zones.
Common failure modes (how contamination happens)
- Face touching / eyewear adjustment: transfers contamination to gloves, then to product-contact surfaces.
- Uncontrolled storage: eyewear placed on benches or carts becomes a contamination pickup point.
- Unqualified cleaners: can haze polycarbonate and leave films that reduce visibility and drive more adjustments.
- Annex 1 mismatch: open safety glasses used where sealed/sterile goggles are required.
SOSCleanroom note about SOP's
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, equipment, cleanroom classification, and regulatory obligations.
Always confirm suitability, cleaning compatibility, 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 process.
Use these best-practice suggestions to strengthen your SOPs—not to replace them.
