About the Flexon J4020
The Flexon J4020 is a men's rectangular frame made from injected ultem with a full rim design. The rectangular shape provides structured, angular lines that complement oval and round face shapes.
This frame comes in one size: 49-15-130, with a lens height of 32mm. The 49mm lens width falls on the narrow side of regular, and the 15mm bridge is narrow for this lens width, suiting those with closer-set eyes or a lower nose bridge. The 130mm temples are short compared to standard lengths, so if your current glasses measure 135mm or longer at the temple, these will sit differently on your ears.
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 is the J4020?
It comes in one size, 49-15-130. If the first number on the temple of your current glasses is 47–51 mm, it will fit you in a similar way.
Is the J4020 good for progressive lenses?
The lens height is 32 mm. That works with progressive, OmniLux® NAL® and iLux™ lenses.
What colors does the J4020 come in?
It is offered in 4 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.
