About the Nike 4321 Eyeglasses
The Nike 4321 is a full rim metal frame made from Flexon material and designed for men. The full rim construction provides complete lens enclosure in a metal build.
This frame comes in two sizes: 55-17-145 with a 39 mm lens height, and 57-17-145 with a 41 mm lens height. The lens width of 55 mm to 57 mm is wide, while the 17 mm bridge is average for frames with this lens width, and the 145 mm temple length is standard. To compare with glasses you currently own, check the three numbers 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, 55 or 57?
Check the first number on the temple of your current glasses. If it is 54–56 mm take the 55; if it is 56–58 mm take the 57.
Is the 4321 good for progressive lenses?
The lens height is 39 mm in the 55 and 41 mm in the 57. That works with progressive, OmniLux® NAL® and iLux™ lenses.
What colors does the 4321 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.
