Why eye protection belongs in a gowning conversation
In controlled environments, eye protection is not only an EHS requirement—it is also a contamination-control touchpoint.
When eyewear fogs, slips, or scratches, operators adjust it more often, increasing face-touch events and the probability of particle and skin-shed transfer.
A consistent eyewear selection and a disciplined donning method help reduce those preventable touches.
What this product is
Manufacturer code 28637 is listed as V30 Nemesis* Polarized Safety Eyewear with a brown polarized polycarbonate lens and brown frame.
The manufacturer product information lists VLT 12%, ANSI Z87.1:2010, base curve 8, and 99.9% UVA/UVB/UVC protection.
Frame/temple materials are listed as nylon and the nosepiece as Empilon, with ratcheted temples.
Where customers use it
- Industrial manufacturing and outdoor environments (manufacturer listed).
- Impact/splash and grinding/chipping or shaving/sanding tasks (manufacturer listed).
- Support tasks near controlled environments where eyewear is required and your SOP permits its introduction (site-dependent).

ISO-first: how eyewear fits into a gowning program
ISO cleanroom operations frameworks emphasize a defined operations control program that includes personnel management, training, and a gowning program.
In practice, this means your facility should specify: (a) when eyewear is required, (b) how it is introduced and stored, (c) how it is cleaned, and (d) how it is worn so it does not break face/hood seals or prompt frequent adjustment.
Donning technique (generic template — align to your SOP)
- Handle only by the temples: keep fingers off the lens and the inner face-contact areas.
- Don at the SOP-defined step: commonly after hood/mask placement so eyewear does not compromise facial coverage; some sites specify the opposite to stabilize mask fit. Follow your gowning qualification.
- Set the fit once: adjust temples outside the critical area, then avoid repeated micro-adjustments during work.
- Control fogging correctly: use only approved anti-fog methods/wipes qualified for optics and coatings; avoid improvised chemicals.
- Segregate by area: keep “cleanroom-introduced” eyewear separate from general-plant eyewear to reduce cross-area transfer risk.
Annex 1 (EU): why personnel technique is treated as a critical control
EU GMP Annex 1 frames personnel as a major contamination source in sterile manufacture and explicitly ties contamination prevention to training, behavior, and gowning discipline.
Even when you are not manufacturing sterile medicinal products, many organizations adopt Annex 1 principles to strengthen contamination control strategy expectations (risk-based).
Common failure modes (and how to prevent them)
- Frequent adjustment events: driven by poor fit, fogging, or scratches. Solve with proper selection and approved cleaning methods.
- Cross-area contamination: eyewear set on unclassified surfaces and reintroduced. Use labeled storage and segregation.
- Improvised cleaning chemicals: may haze lenses or degrade coatings. Use only approved wipes/solutions.
- Sunlight/heat storage damage: follow manufacturer storage guidance away from direct sunlight.
Supply continuity: Ansell + SOSCleanroom

continuity of supply, stable product identification, and manufacturer-backed documentation support for EHS and quality review.
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, cleanroom classification, and regulatory obligations.
Always confirm compatibility of cleaning methods with lens materials/coatings and document the approved method within your quality system.
Use these best-practice suggestions to strengthen your SOPs—not to replace them.
