SKU 25704 is the smoke uncoated configuration of the Nemesis VL platform. The fixed smoke tint is intended to reduce visible brightness in bright exterior and high-illumination environments.

The lens should not be represented as having KleenVision™ premium anti-fog treatment, polarization, photochromic response, automatic tint adjustment, or a specialized optical filter for welding, lasers, or infrared radiation.

Visible-light transmission, or VLT, is the percentage of visible light that passes through a lens. At approximately 9% VLT, the smoke lens transmits a relatively small portion of available visible light and provides substantial brightness reduction compared with clear or indoor/outdoor lenses.

• Reduces intense ambient brightness
• Supports work in sunny or highly illuminated outdoor environments
• Helps reduce visual discomfort associated with strong visible light
• Provides much darker viewing than the approximately 50% VLT indoor/outdoor configuration
• May reduce hazard recognition in shaded, enclosed, or dim areas
• Does not automatically lighten when the wearer moves indoors
• Does not selectively filter horizontally reflected glare

The smoke lens uses a fixed tint. It does not automatically become lighter indoors or darker in direct sunlight. Workers entering buildings, vehicles, stairwells, equipment cabs, enclosed structures, shaded spaces, or low-light process areas must confirm that sufficient visibility is maintained.

• Not photochromic
• Not electronically variable
• Not an automatically darkening filter
• Does not respond dynamically to changes in ambient light
• May require replacement with clear eyewear before entering dim spaces
• Eyewear changes must occur only in a safe area where protection can be removed
• The entire work cycle must be assessed before this tint is assigned

The smoke tint reduces overall visible brightness but is not documented as polarized. Polarized lenses use directional filtering to reduce horizontally reflected glare from surfaces such as pavement, water, glass, painted metal, vehicle panels, and polished materials.

• Brightness reduction is not the same as polarization
• Strong reflected glare may remain visible through the smoke lens
• Evaluate polarized eyewear for sustained glare-intensive work
• Do not advertise SKU 25704 as polarized
• Verify compatibility with screens and instrument displays before selecting a polarized alternative

SKU 25704 does not include KleenVision™ premium anti-fog treatment. Fogging may occur when warm, moisture-containing air contacts a cooler lens and condenses into droplets that obscure equipment, walking surfaces, vehicles, tools, labels, and other task-critical information.

Fogging risk may increase during humid weather, rapid temperature changes, strenuous work, heavy perspiration, mask or respirator use, hood use, and transitions between conditioned vehicles or buildings and outdoor environments.

Do not apply improvised household anti-fog products. Unvalidated sprays, waxes, detergent films, and wipes may leave optical residue, alter tint uniformity, damage polycarbonate, 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 weight, bulk, and opaque material around the visual field.

The absence of an opaque upper brow bar helps preserve the wearer’s field of view above eye level. This can be beneficial when inspecting overhead equipment, reading elevated indicators, climbing, operating equipment, 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 low-profile fit beneath certain hoods and head coverings
• Does not provide sealed upper protection from liquids, aerosols, or hazardous dust

Current Ansell documentation specifies an 8.25 base curve for the Nemesis VL platform. Older SKU-specific records may list base curve 8. The legacy value should be treated as a rounded historical reference rather than evidence of a separate frame design.

The 8.25 base-curve lens follows the general contours of the face and extends toward the lateral eye area. This provides broader spectacle-style side coverage than a flatter conventional lens without using separate removable side shields.

• Extends lens coverage toward the sides of the face
• Supports broad peripheral visibility
• Maintains a low-profile sport-style configuration
• Reduces reliance on removable side-shield components
• Depends on wearer-specific facial dimensions and correct positioning
• Does not create sealed splash, dust, aerosol, or gas protection

The soft flexible nosepiece is designed to reduce concentrated pressure, stabilize the lens, channel perspiration away from the eyes, and help prevent downward slippage. 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 limit downward movement
• Stable positioning supports consistent peripheral coverage
• Reduced movement can decrease repeated eyewear adjustment
• The nosepiece should be inspected for tearing, cracking, hardening, residue, deformation, and loss of grip

Flexible temple arms with Comfort Touch soft-grip tips are intended to reduce side pressure and help maintain eyewear position during walking, bending, climbing, equipment operation, inspection, construction, and material-handling tasks.

• Flexible arms accommodate normal head movement
• Soft contact areas help reduce pressure behind the ears
• Grip-oriented tips help limit forward movement
• Low eyewear weight supports prolonged wear
• Stable retention may reduce repeated face touching
• Temple compatibility should be checked with hard hats, earmuffs, respirators, hoods, and face shields
• Loose, cracked, bent, stretched, or deformed temples require replacement

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

Current Ansell documentation identifies the Nemesis VL platform as manufactured to comply with ANSI/ISEA Z87.1-2020 and as Z87+ high-velocity impact rated. Older SKU-specific records may use ANSI Z87.1, ANSI Z87.1+, or earlier-edition terminology.

Current customer-facing content should use the current manufacturer-published standard while preserving legacy wording only where historical or lot-specific traceability is required.

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 goggles or greater enclosure
• Welding, cutting, brazing, and torch work require task-specific filter shades
• Laser work requires wavelength-specific optical-density protection
• Damaged eyewear must be removed from service regardless of its original rating

The polycarbonate lens filters 99.9% of UVA, UVB, and UVC radiation. This ultraviolet-filtration function is separate from the smoke tint’s visible-brightness reduction.

• UV filtration does not make the lens a welding filter
• The smoke tint does not establish infrared-radiation protection
• The lens is not laser-protective eyewear
• The lens has no wavelength-specific optical-density rating
• The lens is not an automatically darkening welding filter
• Task-specific radiation hazards require correctly rated and marked filters
• Visible brightness reduction must not be confused with specialized radiation protection

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 smoke 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 verify 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. Evaluate visibility in direct sun, shade, equipment cabs, vehicles, buildings, and the darkest assigned work location.
11. Repeat the assessment with all required hard hats, masks, respirators, hoods, earmuffs, and face shields.

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

• Helps reduce loss and misplacement
• Keeps the glasses available for immediate reuse
• Reduces the likelihood of placing 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 protective storage case between work periods

• Outdoor construction and site work
• Facility grounds and exterior maintenance
• Transportation terminals and fleet operations
• Loading yards, shipping areas, and material handling
• Utility and public-works operations
• Oil, gas, petrochemical, and energy work
• Outdoor equipment operation
• Bright manufacturing yards and open-bay facilities
• Roofing, paving, and exterior installation work
• Inspection and maintenance in high-illumination areas
• Work requiring upward visibility
• Work involving hard hats where reduced brow interference is beneficial
• General outdoor occupational eye-protection programs

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

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

The employer should identify both the physical eye hazard and the complete range of lighting conditions before assigning this product. A lens may be impact appropriate while still being too dark for portions of the work cycle.

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 approximately 9% VLT smoke lens is generally unsuitable for dim controlled-production or inspection areas. It may be relevant only in bright exterior support, loading, receiving, utility, construction, or maintenance zones where open safety glasses are permitted by site procedure.

• Evaluate the eyewear under the facility’s contamination-control strategy before use
• Confirm that open safety glasses are permitted in the assigned area
• Validate that approximately 9% VLT provides sufficient task illumination
• Do not use for color-critical or low-light inspection without validation
• Use sealed, sterile, or otherwise validated goggles where required by 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
• Use only facility-approved cleaners and compatible low-lint wipes
• Evaluate whether the neck cord is permitted under contamination-control rules
• Select an anti-fog configuration when condensation causes repeated adjustment or removal

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, tint uniformity, 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 smoke lens. Unvalidated products may leave residue, create optical distortion, alter light transmission, change tint uniformity, or damage the polycarbonate surface.

• Use only products approved for polycarbonate safety eyewear
• Evaluate haze, residue, tint shift, 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, tint uniformity, 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
• Uneven tint, spotting, peeling, or visible surface-treatment damage
• Crazing, stress cracking, or chemical damage
• Cracked, hardened, torn, or deformed nosepiece
• Loose, cracked, bent, stretched, or deformed temples
• Damaged or detached soft-grip 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
• Insufficient visibility in any assigned work area

Store the glasses in a cool, clean, and dry location away from 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.

This Technical Vault entry is intended to support product evaluation, procurement, training, optical selection, fit assessment, controlled-environment planning, and workplace PPE review. It does not replace the manufacturer’s instructions, current product markings, wearer-specific fit evaluation, workplace hazard assessment, lighting assessment, exposure-control plan, cleanroom qualification, facility SOP, or regulatory guidance. Verify current certificates, lens treatment, visible-light transmission, chemical compatibility, packaging, and lot-specific documentation when required by the organization’s quality or safety system.

Technical insight: The Nemesis VL 25704 is strongest where substantial brightness reduction, extra-lightweight frameless construction, upward visibility, reduced hard-hat interference, wraparound coverage, Z87+ impact performance, and ultraviolet filtration must work together. Its primary selection limitation is the approximately 9% visible-light transmission, which requires careful evaluation of shaded, indoor, enclosed, and low-light portions of the work cycle.
