Do Integrated Side Shields Make the Ergodyne Skullerz SIXTEN-AFAS Worth It?

If your job puts debris, dust, or splash hazards anywhere except straight ahead, wraparound frames alone leave you exposed. The Ergodyne Skullerz SIXTEN-AFAS Safety Glasses with Integrated Side Shields close that gap with a one-piece polycarbonate design that carries full ANSI/ISEA Z87.1+ high-impact certification and a dual AF/AS lens treatment — at a price point under $15. Short answer: for high-particulate environments where side protection is non-negotiable and budget matters, this is a strong buy.

Ergodyne Skullerz SIXTEN-AFAS Safety Glasses with Integrated Side Shields Review (2026)

Eye Protection › Safety Glasses › Ergodyne Skullerz SIXTEN-AFAS Review

Side-impact eye hazards are documented in every major industrial injury dataset, yet most workers default to frameless or semi-rimless glasses that leave temple zones unprotected. OSHA 29 CFR 1910.133 requires eye and face protection adequate for the hazard — and for environments with airborne particulates, chips, or liquid splash approaching from any angle, that standard demands side coverage. The SIXTEN-AFAS integrates that coverage directly into the frame, eliminating the clip-on side shields that fall off, fog differently, or simply get skipped at the start of a shift.

Ergodyne built the Skullerz line around the idea that safety gear doesn't have to look institutional. The SIXTEN-AFAS carries the AF (anti-fog) and AS (anti-scratch) dual-coating treatment that defines the AFAS sub-line — a meaningful upgrade over uncoated polycarbonate in environments where temperature swings, humidity, or physical contact with the lens are routine. The wraparound geometry provides peripheral visibility while maintaining the enclosed profile needed for ANSI Z87.1+ compliance.

This review is based on verified product specifications, published ANSI/ISEA Z87.1-2020 standard requirements, and category research across the industrial safety eyewear market. No specifications have been fabricated. Where a spec could not be confirmed from the product page or manufacturer documentation, it is not stated.

Verdict: 4.4 / 5

The Ergodyne Skullerz SIXTEN-AFAS delivers certified high-impact protection, dual AF/AS coating, and permanent side coverage in a sub-$15 frame — a compelling value for general industry, construction, and fabrication environments. Minor drawbacks: no OTG sizing, limited lens tint options, and the fixed side-shield geometry won't satisfy users who need removable side protection or a convertible build.

Who the Ergodyne Skullerz SIXTEN-AFAS Is For

This model is purpose-built for workers in general industry, light construction, fabrication, and warehousing who face multi-directional particulate hazards and need ANSI-certified protection on a per-unit budget. The integrated side shield design is especially relevant for:

• Grinding and cutting operations where chips approach from oblique angles
• Assembly and manufacturing with airborne debris in shared workspaces
• Maintenance and facilities roles requiring all-day wear with anti-fog performance near HVAC equipment or cold storage
• Safety managers bulk-buying PPE who need consistent Z87.1+ coverage across a crew without per-person adjustment overhead

Workers who need OTG compatibility, a convertible (removable) side-shield configuration, welding-rated lens tints, or foam dust-seal protection should explore the broader Safety Glasses Collection or the goggle tier in our Eye Protection Collection.

What the SIXTEN-AFAS Does Well

ANSI/ISEA Z87.1+ High-Impact Certification

The "+" in Z87.1+ is load-bearing. Per the ANSI Z87.1 Safety Glasses Standard Explained, the plus designation indicates the lens passed high-velocity (87 m/s) and high-mass impact tests — a substantially higher bar than the basic Z87.1 mark. Polycarbonate lenses are the standard material for achieving this rating while maintaining optical clarity and light weight. Every variant of the SIXTEN-AFAS carries this certification, meaning the protection level is consistent across Clear, Smoke, and Tan configurations.

Dual AF/AS Coating — Anti-Fog and Anti-Scratch Together

Most entry-level safety glasses offer one coating or the other. Ergodyne's AFAS designation combines both. Anti-fog (AF) coating is chemically distinct from anti-scratch (AS) hardcoat — they operate on different surface mechanisms, and layering them correctly without degrading either requires manufacturing precision. For workers moving between cold storage and warm production floors, or anyone whose work generates heat and humidity, the AF layer meaningfully extends lens clarity between wipes. For our full breakdown of anti-fog options across the market, see our Best Anti-Fog Safety Glasses guide.

Integrated Side Shields — One-Piece Protection, Zero Clip-On Failure Points

Clip-on side shields introduce three failure modes: they can fall off during use, they can be left in a locker, and they can fog or scratch independently of the primary lens. Integrated side shields eliminate all three. The SIXTEN-AFAS achieves this without the bulk of a full goggle — the side coverage is structural, not added-on, keeping the overall profile compatible with most hard-hat systems and face shield adapters. See our breakdown of Safety Glasses vs Safety Goggles to understand when integrated shields are sufficient versus when a sealed goggle is required.

Adjustable Fit System

The adjustable nose piece paired with rubber overmold temple tips gives the SIXTEN-AFAS a fit range that accommodates a wider spread of facial geometries than fixed-bridge designs. Rubber temple tips grip the ear without the pressure that hard plastic creates over long shifts. This is relevant for all-day-wear applications where comfort drives compliance — workers who find their glasses uncomfortable will push them up or take them off, defeating the protection entirely.

Value Density at Sub-$15

At the price point confirmed for this model, the SIXTEN-AFAS stacks ANSI Z87.1+ certification, dual AF/AS coating, and integrated side shields in a single frame. Comparable certified frames with clip-on side shields often cost more when the shield accessories are factored in. For safety managers equipping multiple workers, the per-unit cost advantage compounds. Bulk PPE procurement decisions should weigh total cost of coverage, not just sticker price per frame.

Where the SIXTEN-AFAS Falls Short

No OTG Compatibility

Workers who wear prescription eyewear have two compliant paths: OTG (over-the-glasses) safety glasses sized to fit over prescriptions, or prescription safety eyewear. The SIXTEN-AFAS is neither — its frame geometry is designed for direct wear, not over-frame sizing. This is a meaningful exclusion for a significant fraction of the industrial workforce. If OTG fit is required, see our Best Safety Glasses for Work guide for OTG-rated options.

Fixed Side Shields Limit Versatility

The integrated side shield is the product's core advantage — but it's also a constraint. Workers who alternate between high-particulate environments and tasks where lateral visibility or ventilation is prioritized cannot convert the SIXTEN-AFAS to an open-frame configuration. If your work context changes shift-to-shift between side-hazard and non-side-hazard tasks, a convertible-side-shield model may serve better than a fixed-shield frame.

No Lens Tint Breadth for Specialty Applications

Clear, Smoke, and Tan cover the most common indoor/outdoor/moderate-glare scenarios, but the SIXTEN-AFAS line does not include polarized, IR-filtered, or welding-rated lens options. Outdoor workers managing intense glare will want to evaluate polarized options — see our Best Polarized Safety Glasses guide. Welding applications require shade-rated lenses — see Best Welding Safety Glasses.

No Dust Seal or Foam Gasket

The SIXTEN-AFAS is a safety glasses frame, not a goggle. There is no foam dust gasket or sealed lens-to-face interface. For fine-dust environments (woodworking, drywall, chemical powder handling) or liquid splash hazards requiring sealed protection, the correct PPE is a safety goggle. The side shields provide Z87.1+ lateral coverage but do not create the sealed perimeter a dust/splash goggle provides. Know the difference before selecting this frame for chemical environments.

How the SIXTEN-AFAS Compares to Competitors

Ergodyne Skullerz Safety Glasses: Which Model Fits Your Hazard?

• Choose SIXTEN-AFAS if your hazard profile includes side-impact debris and you need anti-fog performance in a single frame.
• Choose ODIN if side shields are not required but anti-fog coating is the priority in an open, ventilated frame.
• Choose THOR if budget is the sole driver and anti-fog is not needed.

Compatible Accessories

The SIXTEN-AFAS AF coating extends lens life, but supplemental accessories support performance across longer service cycles and multi-hazard environments.

• Lens cleaning wipes: Pre-moistened lens wipes maintain coating integrity without abrasion from shop rags or clothing. Available in bulk — see Eye Protection accessories.
• Anti-fog spray/treatment: For environments where AF coating degradation occurs over time, a liquid anti-fog treatment can supplement or extend lens clarity. Anti-fog spray on Amazon.
• Hard hat adapter/brow pad: The SIXTEN-AFAS is compatible with most standard hard hat brow guards. For complete head-eye systems, see our Welding Safety Collection for integrated face shield systems.
• Protective eyewear cases/pouches: Soft microfiber pouches protect the AS-coated lens during transport. Eyewear pouches on Amazon.

Understanding Safety Glasses Standards: ANSI Z87.1, Anti-Fog, and Side Protection

The ANSI/ISEA Z87.1-2020 standard is the primary U.S. benchmark for protective eyewear. It covers impact resistance, optical quality, lens coverage area, and marking requirements. The "+" suffix designates high-velocity and high-mass impact test passage — not all frames sold as "safety glasses" carry this mark. Frames and lenses are tested and marked independently; a compliant product must have both a marked frame and a marked lens.

Anti-fog performance matters whenever lens temperature differs from ambient air — cold storage, humid production, welding adjacent areas, or transitions between air-conditioned offices and outdoor worksites. AF coatings reduce surface tension on the lens, preventing micro-droplet condensation. They are not permanent; cleaning method and frequency affect longevity. The Best Anti-Fog Safety Glasses guide covers maintenance practices to extend AF performance.

Side shields address a real gap in safety glass coverage. The Z87.1 standard defines a minimum lens coverage area for the front of the eye, but does not mandate lateral protection — that requirement comes from the employer's hazard assessment under OSHA 1910.133. Integrated side shields are architecturally superior to removable clip-ons for sustained compliance because they cannot be inadvertently separated from the frame. Understanding when side shields are mandatory versus optional is covered in our Safety Glasses vs Safety Goggles guide.

For workers requiring reading assistance, see our Bifocal and Reader Safety Glasses Guide — bifocal safety glasses are distinct from OTG frames and address a different accommodation need.

Total Cost of Ownership

At approximately $13-15 per unit, the SIXTEN-AFAS is positioned in the value tier of certified safety eyewear. Assuming a 6-month service cycle for coated polycarbonate lenses in moderate-use environments (daily wear, standard cleaning, no direct chemical exposure), the per-day cost runs approximately $0.07-0.08 per day — essentially negligible relative to the liability and productivity cost of an eye injury.

Replacement drivers for coated polycarbonate safety glasses include:

• Visible scratches in the primary field of vision (optical distortion risk)
• AF coating failure — persistent fogging despite proper cleaning
• Frame deformation from heat, impact, or chemical exposure
• Any impact event, even without visible lens damage (internal stress fractures may not be visible)

For bulk procurement: at 10 units, the per-worker annual cost for two rotation pairs remains under $30 — making the SIXTEN-AFAS one of the most cost-efficient paths to ANSI Z87.1+ side-shield compliance on the market.

Final Verdict: Should You Buy the Ergodyne Skullerz SIXTEN-AFAS?

The SIXTEN-AFAS earns its place at the top of the value-tier safety glasses category. ANSI/ISEA Z87.1+ certification, dual AF/AS coating, and integrated side shields in a sub-$15 frame is a combination that few competitors match at this price point. The wraparound polycarbonate design, adjustable nose piece, and rubber temple tips indicate a product engineered for real all-day wear, not just checkbox compliance.

Buy this if: You need ANSI Z87.1+ certified side-shield coverage with anti-fog performance for general industry, construction, fabrication, or maintenance applications, and per-unit cost matters for individual or fleet purchasing.

Buy something else if: You wear prescription eyewear and need OTG fit, you need convertible (removable) side shields, you require polarized or welding-rated lens tints, or your hazard requires a sealed dust/splash goggle rather than an open-frame safety glass.

Rating: 4.4 / 5 — Recommended for side-hazard environments on a value budget.

Frequently Asked Questions

Are the Ergodyne Skullerz SIXTEN-AFAS safety glasses ANSI Z87.1+ certified?

Yes. The SIXTEN-AFAS carries the ANSI/ISEA Z87.1+ marking, indicating passage of both high-velocity (small projectile at 87 m/s) and high-mass impact tests. This is the highest impact rating under the Z87.1 standard. For a full breakdown of what Z87.1 certification levels mean, see our ANSI Z87.1 Safety Glasses Standard Explained guide.

What does AFAS mean on Ergodyne safety glasses?

AFAS stands for Anti-Fog Anti-Scratch — Ergodyne's designation for lenses that carry both coating types. Anti-fog (AF) prevents condensation on the lens surface; anti-scratch (AS) is a hardcoat that protects polycarbonate from abrasion. Models without the AFAS suffix carry only anti-scratch coating as standard.

Are the side shields on the SIXTEN-AFAS removable or permanent?

The side shields are integrated and permanent — they are part of the frame structure, not a clip-on accessory. This eliminates the risk of misplaced or missing side shields but means the frame cannot be converted to an open-temple configuration. If you need convertible side shields, the 3M Virtua CCS is an alternative to evaluate.

Can the SIXTEN-AFAS be worn over prescription glasses (OTG)?

No. The SIXTEN-AFAS is designed for direct wear and is not sized to fit over standard prescription eyewear frames. Workers requiring OTG compatibility should look for glasses specifically designated OTG in the Safety Glasses Collection, or review options in our Best Safety Glasses for Work guide.

Does the SIXTEN-AFAS anti-fog coating work in high-humidity or cold environments?

AF-coated lenses are designed to reduce condensation in temperature-differential environments — cold storage ingress/egress, humid manufacturing, or transitions from air-conditioned spaces to outdoor heat. No AF coating is permanent or 100% effective under extreme temperature swings. Proper cleaning with lens-safe solutions (not abrasive cloths) extends coating life. See our Best Anti-Fog Safety Glasses guide for maintenance best practices.

What lens tint options are available for the SIXTEN-AFAS?

Three tint options are available: Clear (indoor/low-light), Smoke (bright outdoor conditions), and Tan/Brown (moderate outdoor and overcast conditions). No polarized, IR-filtered, or welding-shade variants are available in this model line.

Is the SIXTEN-AFAS compliant with OSHA 29 CFR 1910.133?

The SIXTEN-AFAS meets the equipment standard referenced by OSHA 29 CFR 1910.133, which requires eye protection to meet ANSI Z87.1. Whether it is the correct selection for a specific workplace depends on the employer's hazard assessment — OSHA requires that the PPE selected be appropriate for the hazard, not just Z87.1-certified in general.

How do integrated side shields compare to clip-on side shields for OSHA compliance?

Both integrated and clip-on side shields can satisfy the lateral protection requirement when properly attached and Z87.1-compliant. The practical difference is compliance consistency: integrated shields cannot be inadvertently removed or forgotten, while clip-on side shields require a separate step each wear. Safety managers responsible for sustained compliance in high-hazard environments generally prefer integrated designs for this reason.

What is the difference between safety glasses with side shields and safety goggles?

Side shields on safety glasses extend the frame's lateral coverage but do not create a sealed perimeter around the eye. Safety goggles feature a foam or rubber gasket that seals the lens against the face, providing protection from fine dust and liquid splash. For a detailed comparison, see our Safety Glasses vs Safety Goggles guide.

How long do the AF/AS coatings last on the SIXTEN-AFAS?

Coating longevity depends on cleaning method, frequency of use, and chemical exposure. Under daily industrial use with proper cleaning (lens wipes or mild soap and water, not abrasive shop rags), AF coatings typically perform for 6-12 months before degradation becomes noticeable. AS hardcoats generally outlast AF coatings under the same conditions. Replace when visible scratching affects optical clarity or when fogging becomes persistent despite cleaning.

What is the polycarbonate lens frame style on the SIXTEN-AFAS?

The SIXTEN-AFAS features a full-frame wraparound design with a polycarbonate lens. The wraparound geometry provides forward and peripheral coverage while the integrated side shields extend lateral protection beyond the wraparound frame arc. The temple arms include rubber overmold tips for grip and comfort.

Are the Ergodyne Skullerz SIXTEN-AFAS glasses good for outdoor use?

The Smoke and Tan tint options are suitable for outdoor use under bright and moderate light conditions respectively. The AF coating is useful for workers transitioning between outdoor heat and air-conditioned vehicles or facilities. The lenses do not include polarization, which limits glare reduction versus polarized options. For outdoor applications where glare is the primary concern, see our Best Polarized Safety Glasses guide.

How does the SIXTEN-AFAS fit compared to other Ergodyne Skullerz models?

The SIXTEN-AFAS includes an adjustable nose piece and rubber overmold temple tips, giving it a wider fit range than fixed-bridge designs. Ergodyne's Skullerz line spans multiple frame geometries — users between standard and large sizing should confirm frame width dimensions before bulk ordering.

Can the SIXTEN-AFAS be used for welding applications?

No. Welding applications require lens shades rated for optical radiation — the SIXTEN-AFAS does not include IR-filtered or shade-rated lenses. It is not appropriate for direct arc welding. See our Best Welding Safety Glasses guide for appropriate options.

What is the price of the Ergodyne Skullerz SIXTEN-AFAS and where can I buy it?
