About the NASCAR N30
The NASCAR N30 is a full rim frame with spring hinges for flexibility and durability. This unisex design works for wearers who prefer a substantial frame presence.
This frame comes in one size: 56-17-140 mm (lens width, bridge width, temple length). The 56 mm lens width is wide, providing good coverage, while the 17 mm bridge is average for this lens width. To compare with your current glasses, check the numbers printed on the inside of the 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 is the N30?
It comes in one size, 56-17-140. If the first number on the temple of your current glasses is 54–58 mm, it will fit you in a similar way.
Is the N30 good for progressive lenses?
Yes. Progressive, OmniLux® NAL® and iLux™ lenses can be made in this frame. If you would like us to confirm the fit for your prescription, contact us before you order.
What are spring hinges?
A small spring in the hinge lets the temple flex outward slightly, which reduces pressure at the sides of your head and helps the frame last.
Prescription lens options for the NASCAR NCO N30

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.
