Material Technology

Polycarbonate is the material of choice for safety eyewear lenses, due to its strength, optical clarity, design and versatility. Developments in these areas, along with concurrent advances in injection molding techniques, have resulted in the production of lenses that not only meet all applicable standards, but also significantly exceed them. Today you will find safety eyewear that passes military V0 ballistic impact tests. To pass this test, the eyewear must withstand the impact of a projectile traveling at 650 feet per second. Plus, polycarbonate lenses are light weight and have high optical clarity, which helps to eliminate eye fatigue and discomfort for wearers. They also provide full UV protection.

Technological advances in other plastic materials—specifically thermoplastic elastomers (TPEs) and thermoplastic urethanes (TPUs)—along with advanced molding techniques have also led to new, innovative comfort technologies. For example, Uvex® pioneered MMT – Multi-Material Technology® process which permanently bonds a soft material to a hard plastic material. The bonding of the soft elastomer on the inside of the frame or goggle body provides a superior level of comfort by cushioning all points of contact to the face. Benefits of this process include an ultra-soft flexible nose bridge, brow guards that cushion the wearer’s face in the event of an impact, and firm yet pliant temple guards that cushion behind the ears to improve comfort for all-day wear.

Design Innovations

In-mold assembly and other advanced techniques have made eyewear more efficient to manufacture, but the real advances have come from imaginative design. Uvex Eyewear designers & engineers have devised a wealth of features and style options to give safety officers and eyewear users more choices than ever before. All aimed at improving performance, comfort, and protection. These design innovations include:

• Wraparound lenses that provide improved peripheral vision and side protection;

• Lens designs that improve ventilation and minimize fogging;

• Soft nosepieces that adjust to provide a precise fit for almost any nose;

• Quick and economical lens replacement systems;

• Temple arms that extend and contract or ratchet to change lens position;

• Multi-Material Technology that positions cushioned comfort at all points of contact with the face and diffuses and deflects impact;

• Lenses with enhanced UV protection, improved scratch resistance and anti-fog coatings;

• Magnifying lenses; tinted, mirrored and polarized safety glass lens options;

• Flip-up style lenses for workers in special environments; and

• Cool colors and design features for style-conscious wearers.
