Product Description:
Many people frequently struggle to find reliable eye protection that they can wear all day. Workers frequently remove standard plastic safety frames during crucial activities because they appear heavy and eventually lose their shape. Invincible Safety Eyewear 301M combines rugged protection with fashionable design to create an elegant look that works well in the workplace. The large unisex frame, with a customizable 54mm eye length and sturdy full-rim shape, is comfortably shaped across a variety of face types.
Traditional goggles can feel uncomfortable, pinching nostrils or ears, often causing users to repeatedly change or remove them. The 301M solves these everyday comfort issues at once with its lightweight, steel frame. The material maintains its unique shape even through heavy use and temperature changes, ensuring that the glasses stay nicely aligned on the face without slipping or creating annoying pressure points.

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.
