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

Frame Width

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

Temple Length

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 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.

Tactical Style and Durability

These glasses have a tough feel to them. The rectangular lenses provide a wonderful peripheral view that is crucial when you're on the go, and the finish is durable and doesn't flake off like cheaper brands. I picked up the Camo version for my outdoor hobby work, and I'm impressed.

The Perfect Modern Fit

I have struggled to find Unisex frames that don't look too bulky, but the Rectangular Shape of the GRXS04 is spot on. It provides a sharp, clean look that frames my face perfectly. The Full Rim construction feels solid and high-quality without being heavy on the bridge of my nose.

Love the Vibrant Purple

I am so tired of boring black frames, so I was thrilled to find these in Purple. The color is rich and deep, and the Gloss Black accents truly make them stand out. They're fashionable enough for weekend trips yet durable enough to wear when working in my home studio.
