Triloid™ Nylon is the toughest non-metal material available. It not only gives you lightweight comfort, but it also extremely strong. Among other, it is thanks to this highly durable material that WX eyewear can withstand the rigorous safety tests that we certify all our eyewear to. It might have a light and plastic feel, but TriloidTM Nylon is much stronger and of a higher quality.
The eyewear can be fitted with prescription lenses to match your optical needs. If you need prescription lenses, please reach out to a Wiley X optician near you and they will assist you in constructing prescription lenses for your WX eyewear, either directly into the lenses or using a prescription insert, depending on your Wiley X eyewear model.
With the attached Facial Cavity™ Seal you can control the influence of the outer elements from distorting your vision. The Facial Cavity™ Seal will block out any irritants, including wind, dust, and depris, but it will also block the peripheral light, protecting your eyes and allowing your lenses to perform to their fullest.
Note: The Facial Cavity™ Seal can easily be removed or attached, as needed.
The base curve refers to the curvature of the lenses, which defines how much the frame wraps around your face. The higher the base curve, the larger curvature. Wiley X operates with base curve eight and base curve six, however we do have some models that has a base curve between and under these two values.
Base curve eight means that the eyewear has a large curvature and a high wrap fit, meaning that the eyewear will enclose your face to a greater extent, which also will ensure you better protection against light in your peripheral field of view.
Base curve six lenses that are less curved than eyewear with a base curve eight. They have a medium wrap fit, meaning that they do not enclose your face in the same way, but rather sit flatter against your face. This makes them fit more face types and sizes better.
Picking out the perfect pair of eyewear or sunglasses can be difficult, because how do you know if it will fit your head? First step is to determine your head size. If you know the circumference (the measurement around your head), it will be much easier to know if the eyewear will fit you. Simply, take out a tape measure and measure the circumference of your head. Compare the number you get with the table you see above.
For instance, if your head has a circumference of 58 cm you have a large head size, and your face should be able to fit all our models that covers this head size. Many of our models have more than one fitting head size, for instance M-L.
This means that if your head size is either medium or large, you will be able to fit this model.
The frame width refers to the distance between the ends of your frame, including the hinges. To achieve the best result, both in terms of look and fit, the frame width and the width of your face, should correspond fairly. If the frame is too wide, you can risk that the eyewear will look too oversized to your face, and there might be a greater risk for the eyewear to slide down and your view being distorted. A too narrow frame can on the other seem too small for your face and pressure against your temples, potentially leading to headaches.
The bridge width is the measurement between your two lenes, meaning the space where the frame fit against your nose. It is important that the bridge of your eyewear fits the width of your nose. If the bridge width is too wide, the eyewear will slide down your nose. If the bridge width is too narrow, the eyewear will pressure to much against your nose, causing pressure points that can be uncomfortable.
The temple length (arm length) is crucial for a secure fit. If they are too long to your face, the eyewear will slide right of. If they are too short, the eyewear will pressure against your temples, ears, and nose. The temple length is measured from the screw to the temple tip, including any bend the design might have.
ANSI Z87.1 tested means that the frame and lenses meet or exceed specific safety ratings set by the American National Standards Institute (ANSI), who has developed a certification system for safety eyewear in the US. As an American brand, we test our eyewear to pass a high velocity impact test and a high mass impact test, as dictated by ANSI.
The high velocity impact test demands that the frame and lenses must withstand the impact of a 6,35 mm steel ball fired at 164,6 km/h, while remaining intact. The high mass impact test demands that the frame and lenses must remain intact while withstanding a 500 grams pointed projectile that is dropped down on the eyewear from a height of 127 cm.
EN 166B is the European standard for goggles. A test according to EN 166B means that both the frame and the lenses must meet a standard that ensures protection against medium-energy impact. The goggle must be able to withstand the impact of a 6 mm steel ball weighing 86 g, fired at a velocity of 432 km/h. To pass the test, the lens must remain intact and stay secured within the frame.
This test is an excellent mark of quality for goggles, as it guarantees the same high level of safety and quality required by soldiers around the world.
When creating SPEAR, we took the traditional goggle format and added purpose-driven features to maximize comfort and protection. It has a SPEAR Elastic Strap with Tri-Glide™ System, so you can adjust the length, as well as quick release key connections. It is compatible with both the Wiley X ARC Rail Attachment System (RAS) and the Team Wendy Rail Attachment System (RAS), providing you a secure and comfortable fit, when using either a tactical helmet with ARC rails or and Team Wendy EXFIL® helmet. Additionally, it has a removable Facial Cavity™ Seal for added defense against pollutants and irritants. This, matched with its symmetrical venting system and its NVG compatibility, the SPEAR is a solid and versatile addition to your arsenal of protective equipment.
Can be made with prescription lenses, using a prescription Insert (PTX). To find a Wiley X partner near you, who can make prescription lenses, use our Dealer Locator to find an optician.
