Product Description
Dealing with an uncomfortable fit or poor visibility should never be a part of staying safe on a busy job site. All too frequently, when performing busy jobs, safety managers give rigid plastic glasses that pinch, fog up, or slide down the nose bridge. The Invincible Safety Eyewear 103Z gives safety directors a reliable instrument to protect their employees by combining a classic rectangular shape with long-lasting industrial protection.
Because of its flexible 56mm eye size and robust full-rim structural construction, this large-frame unisex model will fit a range of face shapes. It comes in a conventional tortoise-shell design or a striking black finish. The frame's use of a high-performance rubber composite eliminates the pressure areas that usually lead workers to remove their equipment while allowing it to flex naturally to absorb sudden impacts.

Finding safety equipment that employees are eager to wear all day might be a challenge. Hard plastic alternatives easily lose shape and slip when workers sweat or tilt their heads, resulting in dangerous blind spots. The 103Z tackles these everyday comfort issues directly with its innovative rubber structure. The material naturally sticks to the skin, keeping the frames securely in place during active shifts without irritating the face.

FRAME MEASUREMENTS
To ensure your frames fit perfectly, you first have to determine which size frames are best for you. The best place to start is with the measurements on a pair you already own. You know those little numbers on the inside of its temple? That's what you're looking for. The frame measurements appear in the following order: lens width, bridge width, and temple length.
Frame Width

To find frame width, measure the front of the frame from screw to screw
Temple Length

Temple length is the measurement in millimeters of the ‘arms' of the frame. This measurement does not vary as much as the others, with 135mm, 140mm, 145mm, and 150mm being the most common options.
Lens Height and Width

Lens height is the distance from the top of a lens to the bottom. Lens Width is the distance from the left side of a lens to the right side.
