About the Flexon 623

The Flexon 623 is a semi-rimless frame with a round shape. The unisex design works for those who prefer round eyewear without a full rim around the lenses.

This frame comes in two sizes: 46-19-135 with a 39mm lens height, and 48-19-140 with a 41mm lens height. The lens width of 46mm to 48mm is narrow, and the 19mm bridge is average for lenses this width. To compare with your current glasses, check the three numbers printed on the inside of the temple—these frames have shorter 135mm to 140mm temples than many standard frames.

Order the frame on its own or add prescription lenses made in our U.S. lab: single vision, OmniLux® NAL® lenses or progressives, and prescription sunglasses with Transitions®, tinted or polarized lenses. Free U.S. shipping on every order with prescription lenses.

Frequently asked questions

Which size should I choose, 46 or 48?

Check the first number on the temple of your current glasses. If it is 45–47 mm take the 46; if it is 47–49 mm take the 48.

Is the 623 good for progressive lenses?

The lens height is 39 mm in the 46 and 41 mm in the 48. That works with progressive, OmniLux® NAL® and iLux™ lenses.

What does semi-rimless mean?

A metal rim holds the top of the lens and a fine cord holds the bottom edge, so the frame looks lighter than a full-rim style.
