    Under Armour ArmourSight Lens</p><p>Technology Diagram


    ArmourSight provides the

    wearer with up to 20% enhanced vision edge to edge, delivered in a

    lens that is up to 10 times stronger than polycarbonate lenses.

    ArmourSight Lenses have rendered conventional decentered lenses


    The military-inspired ArmourSight polymer was created to withstand

    violent impact, translating into the ultimate protection in training

    and on the field of play. ArmourSight Lenses eliminate all

    peripheral distortion, resulting in an increased field of vision

    that improves reaction time and overall performance. Additionally,

    ArmourSight Lenses can accommodate customized, sport-specific tints

    (available in several Under Armour styles), which sharpen contrast

    and illuminate objects by separating them from their backgrounds.

    Under Armour 2 Point Grip System</p><p>Diagram


    ArmourFusion frames flex and

    retain their shape through the toughest conditions. Combining the

    element Titanium, which has the highest strength-to-weight ratio of

    any metal known to man, with Grilamid, a durable cutting-edge

    thermoplastic, results in ultra-lightweight, impact-resistant

    sunglass frames.
