Size Guide

Frame Size Guide: How To Measure Your Eyeglasses

Lens width Lens width

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.

About Flexon

Flexon

Since its foundation in 1988, Flexon has always been at the forefront of innovations in the eyewear industry. The company was among the first to utilize top-quality Japanese materials and cutting-edge technologies to create revolutionary titanium eyewear.

Flexon frames are constructed from unique titanium composite that, in comparison to other metal alloys, allows it to remember and come back to its original shape after being flexed or accidentally bent.

Over the years, many eyewear manufacturers have tried to imitate the new technology, but Flexon is and will always be the groundbreaker. Flexible. Durable. Strong. These are the main features that make the Flexon glasses stand out from the rest.

Exceptionally light, flexible, and titanium strong, Flexon frames perform like no other standard metal frames available on the market. Whether bent and stretched, or twisted and pulled, Flexon eyewear ″remembers″ its original form and reclaims it in no time.
