About the Flexon 603
The Flexon 603 is a full rim rectangular metal frame with a unisex design. The Flexon material is a metal alloy known for flexibility and durability. Regular hinges complete the construction.
This frame comes in two sizes: 49-19-140 with a 30mm lens height, and 51-19-145 with a 31mm lens height. The lens widths of 49mm and 51mm fall on the narrow side of regular, while the 19mm bridge is average for frames in this lens width range. To compare with glasses you already own, measure the lens width printed on the inside of your temple arm.
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, 49 or 51?
Check the first number on the temple of your current glasses. If it is 48–50 mm take the 49; if it is 50–52 mm take the 51.
Is the 603 good for progressive lenses?
The lens height is 30 mm in the 49 and 31 mm in the 51. That works with progressive, OmniLux® NAL® and iLux™ lenses.
What colors does the 603 come in?
It is offered in 3 colors; the product page shows which are available now.
If you already own a pair of glasses, you'll find numbers engraved on the inside of the eyewear temple. These numbers indicate the following:
LENSWIDTH (A)—
BRIDGEWIDTH (DBL)—
TEMPLELENGTH—
LENSHEIGHT (B)—
The first number is the lens width followed by the bridge width. The third number represents the temple length, or the measurement of the arms of your frame. In some cases there may be a fourth number that indicates the lens height. Measurements in mm.
