WX Dual Lens System
Each interchangeable shield uses two layers to help reduce fogging caused by differences between internal and external air temperatures.
The Wiley X Spear Dual Lens protective goggles include three interchangeable two-layer shields: Clear, Grey and Light Rust. The WX Dual Lens System helps reduce fogging caused by temperature differences between the inside and outside air. A removable Facial Cavity™ Seal, adjustable Matte Black goggle frame and defined military fragment-impact testing support demanding tactical use.
Product description
The Dual Lens designation describes the construction of each shield rather than the number supplied. Each interchangeable shield uses two layers that help separate the temperature difference between the air inside and outside the goggles, reducing the likelihood of fogging. An anti-fog coating and symmetrical ventilation provide additional fog-management support.
Clear, Grey and Light Rust shields allow the same goggles to be adapted for untinted reduced-light, bright outdoor and contrast-enhancing conditions. A removable Facial Cavity™ Seal helps reduce the entry of wind, dust, debris and peripheral light.
The adjustable SPEAR elastic strap has a Tri-Glide™ system and quick-release key connections for securing the goggles during use.
Key features
Three-shield configuration
Clear, Grey and Light Rust options adapt the goggles to substantially different light conditions.
Environmental management
A removable Facial Cavity™ Seal and symmetrical ventilation help manage environmental intrusion and airflow.
Tactical integration
Compatible with night vision equipment and separately sold ARC and Team Wendy EXFIL® rail attachment systems.
Adjustable retention
The SPEAR elastic strap uses a Tri-Glide™ system for length adjustment and quick-release key connections.
Defence identification
The Matte Black configuration is listed as APEL approved and has NATO Stock Number 4240-01-600-1785.
Recommended use
The Spear Dual Lens goggles are suited to tactical and professional activities involving changing light, temperature differences, airborne irritants and the use of helmet-mounted or night vision equipment.
Their fog-management features are particularly relevant where shifts in temperature or activity may encourage condensation. The Facial Cavity™ Seal helps limit environmental intrusion but does not create a completely sealed enclosure.
Fit & comfort
Designed to adjust, built to stay secure
The adjustable Matte Black goggle frame is made from lightweight, durable Triloid™ Nylon and is designed for medium to 2XL head sizes. Its non-glossy finish gives it a subdued appearance, while the removable Facial Cavity™ Seal forms a soft foam barrier around the eyes.

Shield details
Clear
81% light transmissionThe Clear shield allows a high proportion of available light through without adding a tint. It is intended for indoor use and reduced-light conditions such as dawn, dusk, haze and overcast weather.
Grey
14% light transmissionThe Grey shield reduces intense glare and brightness while keeping colours close to their natural appearance. It is intended for strong sunlight and other bright outdoor conditions.
Light Rust
47% light transmissionThe Light Rust shield filters blue light to help reduce glare and haze while increasing contrast. It is intended for medium- to low-light conditions where distinguishing details and differences between objects may otherwise be more difficult.
Each shield uses the two-layer WX Dual Lens construction and has a hard, anti-fog coating. The shields are made from strong, durable Selenite™ polycarbonate and provide 100% UVA and UVB protection. Their T-Shell™ treatment helps resist scratches and limit surface damage, although scratch-resistant does not mean scratch-proof.
Protection backed by defined testing
This configuration is assessed against ANSI Z87.1, MIL-PRF-32432A, EN.166B, STANAG 2920/4296.
ANSI Z87.1
Assesses the complete goggles against defined high-velocity and high-mass impact tests. These include a fast-moving 6.35 mm steel ball and a 500 g pointed falling projectile; the goggle frame and shield must remain intact during testing.
MIL-PRF-32432A
Assesses the complete goggle-and-shield system against a defined American military fragment-impact requirement using a .15 calibre projectile travelling at 636–647 km/h.
EN.166B
Assesses the complete goggles against a defined medium-energy impact test using a 6 mm, 86 g steel ball travelling at 432 km/h. The shield must remain intact and secured within the frame.
STANAG 2920/4296
The product specification identifies the Spear Dual Lens goggles as having passed these requirements.
