About the CAT THREAD
The CAT THREAD is a men's full rim frame with a rectangle shape and regular hinges. The rectangular shape typically suits oval, round, and heart-shaped faces.
This frame measures 56-18-145 mm (lens-bridge-temple). The 56 mm lens width is wide, providing substantial coverage, while the 18 mm bridge is average for this lens width. To compare with glasses you already own, 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 THREAD?
It comes in one size, 56-18-145. 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 THREAD 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.
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.
