Technical Vault: KleenGuard™ V30 Nemesis™ VL Safety Glasses 20470

The KleenGuard™ V30 Nemesis™ VL Safety Glasses 20470 are reusable, non-prescription industrial safety glasses engineered around an extra-lightweight frameless, no-brow design. This clear-lens configuration is intended for workers who need high visible-light transmission, high-impact spectacle protection, ultraviolet filtration, broad peripheral coverage, improved upward visibility, reduced hard-hat interference, perspiration management, and comfortable extended wear.

The product combines a clear polycarbonate wraparound lens, gunmetal temple structure, soft flexible nosepiece with a ventilation notch, Comfort Touch soft-grip temple tips, and an included neck cord. The lens is cataloged as clear uncoated and should not be represented as a KleenVision™ anti-fog model. The published visible-light-transmission value is approximately 90%.

This Technical Vault consolidates the product identity, current and legacy geometry references, lens-treatment classification, optical properties, impact performance, ultraviolet filtration, frame construction, fit characteristics, PPE compatibility, controlled-environment considerations, cleaning procedures, inspection criteria, storage guidance, packaging, documentation history, and use limitations. Final selection must be based on the employer’s documented hazard assessment and wearer-specific fit verification.

SKU 20470 is consistently identified in SKU-specific product records as the clear uncoated Nemesis VL configuration. The term distinguishes this model from the clear KleenVision™ anti-fog version, blue-mirror anti-fog version, smoke lens, indoor/outdoor mirror lens, and IRUV variants.

Current Ansell family documentation lists scratch-resistant hardcoat, KleenVision™ anti-fog, mirror, and IRUV treatments as available across the Nemesis VL family. That family-level list does not establish that every treatment applies to every SKU. A scratch-resistant or hardcoat claim should therefore be assigned to 20470 only when supported by the supplied package, current vendor record, lens marking, or lot-specific technical documentation.

Visible-light transmission describes the portion of visible light that passes through the lens. The published value of approximately 90% identifies SKU 20470 as a high-transmission clear lens intended for normally illuminated indoor and general-purpose work.

• Supports natural color recognition
• Supports reading labels, screens, gauges, and process indicators
• Preserves available task illumination
• Supports inspection, checking, and quality-control operations
• Avoids the intentional brightness reduction of smoke or mirror lenses
• Provides clear visibility in warehouses and facility interiors
• Does not provide sunglass-style brightness reduction
• Does not provide polarized control of reflected glare

A high-transmission clear lens is not intended to reduce intense sunlight or reflected exterior glare. Outdoor exposure around pavement, roofing, snow, glass, polished metal, water, vehicles, or other highly reflective surfaces may require an appropriately tinted, mirrored, or polarized safety-eyewear configuration.

• Do not treat the clear lens as a sunglass substitute
• Evaluate glare conditions during the full work cycle
• Confirm that workers transitioning outdoors retain adequate visual comfort
• Select polarized eyewear where directional reflected-glare reduction is required
• Select task-specific filter lenses for welding, laser, or IR hazards

SKU 20470 does not include the KleenVision™ premium anti-fog treatment. Fogging can occur when warm, moisture-containing air contacts a cooler lens and condenses into microscopic droplets that scatter light and obscure task details.

Fogging risk increases with high humidity, rapid temperature changes, strenuous activity, heavy perspiration, mask leakage, respirator exhaust, hoods, and protective garments that redirect warm air toward the lens.

Do not apply improvised household anti-fog products. Unvalidated sprays, waxes, detergent films, and wipes may leave optical residue, damage polycarbonate, alter surface properties, or conflict with controlled-environment cleaning procedures.

The Nemesis VL platform uses the polycarbonate lens as the primary protective structure and eliminates a conventional full upper frame. This frameless architecture reduces bulk and weight while maintaining wraparound coverage.

The absence of a conventional opaque upper brow bar helps preserve the wearer’s field of view when looking above eye level. This can be relevant when inspecting overhead piping, reading elevated indicators, climbing, handling material on upper shelving, or working beneath hard-hat suspension systems.

• Reduces upper-frame visual obstruction
• Supports upward inspection and hazard recognition
• Helps limit contact with hard-hat suspension components
• Supports a lower-profile fit under certain hoods and head coverings
• Does not provide the upper particle coverage of a sealed or brow-enclosed goggle

Current Ansell documentation identifies the Nemesis VL wraparound lens as having an 8.25 base curve. Older SKU-specific records, including legacy product descriptions, may list base curve 8. The difference is best treated as a legacy rounded value versus the current manufacturer specification rather than as evidence of a different product design.

The 8.25 base-curve lens follows the general contours of the face and extends protection toward the sides of the eyes. This geometry provides greater lateral spectacle coverage than a flatter conventional lens without using separately attached side shields.

• Extends the lens toward the lateral eye area
• Supports broad peripheral vision
• Reduces the need for removable side-shield components
• Maintains a low-profile sport-style shape
• Depends on correct facial fit and lens positioning
• Does not create sealed splash, dust, or gas protection

The soft nosepiece is designed to remain flexible, reduce concentrated pressure, help maintain stable lens positioning, and channel perspiration away from the eyes. A ventilation notch supports moisture movement around the nose contact area.

• Soft contact helps reduce pressure on the bridge of the nose
• Flexible construction accommodates a range of facial profiles
• Ventilation notch helps channel perspiration
• Grip-oriented geometry helps reduce downward slippage
• Stable positioning supports consistent peripheral coverage
• Reduced movement can decrease repeated adjustment
• The nosepiece should be inspected for tearing, cracking, residue, deformation, and loss of grip

Flexible temple arms with Comfort Touch soft-grip tips are designed to minimize pressure during extended use and help prevent the eyewear from sliding forward or off the head.

• Flexible arms accommodate normal head movement
• Soft tips help reduce pressure behind the ears
• Grip-oriented contact helps maintain frame position
• Low eyewear weight supports prolonged use
• Stable retention may reduce repeated face touching
• Temple fit should be evaluated with earmuffs, hard hats, respirators, hoods, and face shields
• Loose, cracked, bent, or deformed temples require replacement

Current Ansell product details identify polycarbonate, nylon, thermoplastic elastomer, and metal screw components within the Nemesis VL construction.

Current Ansell documentation identifies the Nemesis VL family as manufactured to comply with ANSI/ISEA Z87.1-2020 and as Z87+ high-velocity impact rated. Older SKU-specific documents may reference ANSI Z87.1+, ANSI Z87.1-2010, or earlier standard editions.

The Z87+ designation addresses high-impact performance under the applicable spectacle requirements. It does not establish sealed protection or suitability for every workplace eye and face hazard.

• High-impact certification does not make the glasses chemical-splash goggles
• Wraparound geometry does not create a dust-tight or gas-tight enclosure
• The no-brow design does not provide sealed upper protection
• A compatible face shield may be required in addition to primary eye protection
• Fine hazardous dust and aerosols may require greater enclosure
• Welding, cutting, brazing, and torch work require filter-shade protection
• Laser work requires wavelength-specific optical-density protection
• Damaged eyewear must be removed from service regardless of its original rating

The clear polycarbonate lens filters 99.9% of UVA, UVB, and UVC radiation while maintaining high visible-light transmission. This supports clear indoor vision and general ultraviolet exposure reduction without using a dark lens tint.

• UV filtration does not make the lens a welding filter
• UV filtration does not establish infrared protection
• The lens is not laser-protective eyewear
• The lens has no specialized optical-density rating
• Task-specific radiation hazards require appropriately rated filters
• Intense exterior glare may require a suitable tinted or polarized configuration

1. Place the glasses on the wearer without excessively spreading the temple arms.
2. Confirm that the soft nosepiece sits securely without painful pressure.
3. Verify that the lens is centered in front of both eyes.
4. Inspect the side and lower lens edges for excessive openings.
5. Ask the wearer to look upward and confirm that the no-brow design preserves the required field of view.
6. Ask the wearer to look downward and from side to side.
7. Ask the wearer to bend, turn, walk, climb, and perform representative task movements.
8. Verify that the eyewear remains secure without repeated adjustment.
9. Confirm that perspiration does not cause excessive slippage.
10. Repeat the assessment with all required hard hats, masks, respirators, hoods, earmuffs, and face shields.

Each pair includes a neck cord to keep the eyewear accessible when temporarily removed. The cord may support intermittent tasks, visitor programs, maintenance workflows, and transitions between areas with different PPE requirements.

• Helps reduce loss and misplacement
• Keeps the glasses available for immediate reuse
• Reduces the likelihood of placing the eyewear on work surfaces
• Should be inspected for damage, contamination, and secure attachment
• Must be evaluated for entanglement risk around moving equipment
• May require removal where cords or loose accessories are prohibited
• Should not replace a protected storage case between work periods

• Manufacturing and production operations
• Assembly, inspection, checking, and quality control
• Packaging, picking, and material handling
• Warehousing, shipping, and receiving
• Construction and general site work
• Facility and equipment maintenance
• Transportation, automotive, and fleet service
• Oil, gas, petrochemical, and energy operations
• Utilities and public-works maintenance
• Indoor work requiring natural color recognition
• Tasks requiring upward visibility
• Work involving hard hats where reduced brow interference is beneficial
• Visitor and contractor eye-protection programs
• Controlled-area support work where open safety glasses are permitted by SOP

The no-brow design is intended to reduce interference with hard-hat suspension systems, but the complete PPE combination must still be evaluated on the individual wearer.

• Confirm that hard-hat suspension components do not push the eyewear downward
• Ensure temples do not cross tight-fitting respirator sealing surfaces
• Check whether masks or respirators direct warm air toward the uncoated lens
• Verify that earmuff cushions remain fully seated around the ears
• Confirm compatibility with hoods, bouffants, and head coverings
• Verify that face-shield brackets do not contact or displace the glasses
• Confirm secure fit during representative movement
• Do not force the glasses over prescription eyewear unless specifically evaluated
• Repeat the compatibility assessment whenever another PPE component changes

The employer should identify the source, direction, frequency, duration, and severity of each eye hazard before selecting protection. Open spectacle-style eyewear may be appropriate for general impact exposure but may not provide sufficient enclosure for liquids, fine dust, aerosols, or multidirectional hazards.

Industrial eye-protection compliance and cleanroom suitability are separate determinations. ANSI/ISEA compliance does not establish sterility, ISO cleanroom classification, low particle release, low outgassing, disinfectant compatibility, or suitability for aseptic processing.

The low-profile design, soft nosepiece, and stable temple contact may help reduce eyewear movement and repeated adjustment. However, the lack of premium anti-fog treatment must be considered where masks, respirators, hoods, high humidity, or temperature changes could produce condensation and additional face-touch behavior.

• Evaluate the eyewear under the facility’s contamination-control strategy before use
• Confirm that open safety glasses are permitted in the applicable controlled area
• Use sealed, sterile, or validated goggles where required by the gowning SOP
• Assign eyewear by employee or controlled area when practical
• Stage cleaned eyewear on the designated clean side of the gowning process
• Handle the glasses by the temples rather than the lens
• Complete fit adjustments before entering the critical work zone
• Do not place eyewear directly on benches, carts, gowning seats, or critical surfaces
• Do not transfer eyewear between uncontrolled and controlled areas without approved cleaning
• Use only facility-approved cleaners and compatible low-lint wipes
• Evaluate whether the neck cord is permitted by the contamination-control program
• Upgrade to an anti-fog model when recurring condensation causes adjustment or removal

1. Inspect the eyewear before beginning the gowning sequence.
2. Clean or disinfect the glasses according to the approved facility procedure.
3. Inspect nosepiece, temple interfaces, screws, and neck-cord attachment points for retained residue.
4. Stage the eyewear in the designated clean-side location.
5. Handle the product only by approved contact points such as the temples.
6. Don the eyewear at the step specified by the gowning SOP.
7. Complete fit positioning before final glove donning when permitted.
8. Confirm compatibility with the mask, respirator, hood, bouffant, and face shield.
9. Observe whether the complete PPE combination causes fogging.
10. Avoid touching or readjusting the glasses in the critical work area.
11. Follow the approved deviation procedure if the glasses are dropped, displaced, contaminated, or fogged.

1. Wash and dry hands or don clean gloves as required by the work area.
2. Inspect the lens for dust, grit, metal particles, dried residue, or abrasive contamination.
3. Remove loose particles with clean air or a gentle water rinse when permitted.
4. Apply an approved optical cleaner, mild soap and water, or another validated cleaning solution.
5. Wipe gently using a soft optical tissue, microfiber cloth, or approved cleanroom wiper.
6. Clean around the nosepiece, temples, screw points, and neck-cord interfaces.
7. Avoid excessive pressure and abrasive wiping.
8. Rinse where required to remove cleaner residue.
9. Dry using a clean, soft, non-abrasive material.
10. Inspect the lens, frame components, nosepiece, temples, screws, cord, and safety markings before reuse.

Do not assume that aftermarket anti-fog sprays, detergent films, waxes, scratch treatments, or disinfectant coatings are compatible with the clear lens. Unvalidated products may leave residue, create optical distortion, alter visible-light transmission, or damage the polycarbonate surface.

• Use only products approved for polycarbonate safety eyewear
• Evaluate haze, residue, and optical distortion after application
• Confirm compatibility with facility cleaning procedures
• Do not obscure required safety markings
• Do not use improvised household products
• Select a factory anti-fog SKU when fog resistance is predictably required

Inspect the eyewear before each use and after any impact, chemical contact, abnormal heat exposure, or cleaning process that could affect protection or optical performance. Remove the product from service when any condition could reduce fit, clarity, impact performance, or structural integrity.

• Cracked, chipped, warped, or deformed lens
• Deep scratches or abrasion that interferes with vision
• Persistent haze, clouding, optical distortion, or discoloration
• Crazing, stress cracking, or chemical damage
• Cracked, hardened, torn, or deformed nosepiece
• Loose, cracked, bent, stretched, or deformed temples
• Damaged or detached soft-grip temple components
• Loose, corroded, or damaged screws
• Loss of secure fit during normal movement
• Excessive side or lower-edge openings caused by deformation or incorrect fit
• Illegible required safety markings
• Exposure to a significant impact event
• Chemical contact that may have degraded the lens or frame
• Residue that cannot be removed through the approved cleaning process
• Recurring fogging that prevents safe task performance

Store the glasses in a cool, clean, and dry location away from direct sunlight, excessive heat, abrasive materials, heavy objects, and chemical vapors. The lens, nosepiece, temples, and cord should be protected from contact, compression, and deformation.

• Use an individual case, sleeve, or designated storage compartment
• Do not store with sharp tools, fasteners, metal parts, or abrasive materials
• Do not place heavy objects on the lens or temples
• Avoid prolonged storage in hot vehicles or near process heat
• Keep away from solvent, adhesive, fuel, and cleaning-chemical vapors
• Store cleaned eyewear separately from contaminated PPE
• Do not allow the lens to rest directly against rough surfaces
• Do not force or flatten the frame during storage
• Use the neck cord as a temporary retention aid rather than long-term storage

Ansell lists the Nemesis VL product family as eligible for the RightCycle™ Program. Actual eligibility, contamination restrictions, geographic availability, collection methods, minimum quantities, and accepted product conditions should be confirmed with the current program before the glasses are placed into a recycling stream.
