About the Jill Stuart JS421
The Jill Stuart JS421 is a women's square frame with full rims and spring hinges. The square shape provides structured definition and works well for those who prefer angular frame styles.
This frame comes in one size: 53-15-135 millimeters (lens width-bridge-temple). The 53mm lens width offers a regular fit, while the 15mm bridge is narrow for this lens width, sitting closer on the nose than many frames with 53mm lenses. The 135mm temples are short compared to standard lengths, so if your current glasses have longer temples, these will sit differently behind 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 JS421?
It comes in one size, 53-15-135. If the first number on the temple of your current glasses is 51–55 mm, it will fit you in a similar way.
Is the JS421 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.
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.
