Frame Size Guide: How To Measure Your Eyeglasses
The first number— the lens size — represents the horizontal width of the lenses. Generally, the eye size of most eyeglass frames ranges from 40 mm to 62 mm.
The second number — the bridge size — is the distance between the lenses. In other words, it's the size of the "bridge" of the frame that rests on your nose. In most cases, the bridge size of eyeglass frames ranges from 14 mm to 24 mm.
The third number — the temple length — is the length of the "stems" of the frame, measured from the frame hinge to the back tip of the temple. Temple lengths generally range from 120 mm to 150 mm.
Often a small square (rather than a dash) will separate the eye size and the bridge size on the frame.

Native Ken makes glasses that don’t try too hard—they just fit your life. The brand started in New York, and there’s a certain calm confidence in every pair. The shapes are familiar but refined: soft squares, rounds, cat-eyes, aviators. They feel balanced on your face, never heavy or awkward. Acetate and metal frames are finished cleanly, with hinges that move smoothly and colors that stay rich over time. You’ll find classic tones like tortoise, black, and smoky gray, plus a few clear or matte options that feel fresh without being loud. Lenses block UV rays, and optical models can handle blue-light filters if you need them. Native Ken isn’t about trends—it’s about glasses you put on once and forget to take off.
Native Ken eyeglasses are designed to deliver crisp, accurate vision with lenses that can be customized for blue-light filtering or prescription needs.
All-Day Comfort FitEach frame is engineered with lightweight materials and balanced geometry, ensuring a secure, pressure-free fit from morning to night.
Refined Everyday DesignWith clean lines and subtle detailing, the brand's optical frames bring a polished, modern touch to any look—professional or casual.
