About the Smart S2831
The Smart S2831 is a women's plastic frame with spring hinges. The spring hinge construction allows the temples to flex outward for additional comfort and durability.
This frame comes in one size: 53-19-145 mm, with a lens height of 36 mm. The 53 mm lens width provides a regular fit, while the 19 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—they follow the same lens-bridge-temple format.
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 S2831?
It comes in one size, 53-19-145. 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 S2831 good for progressive lenses?
The lens height is 36 mm. That works with progressive, OmniLux® NAL® and iLux™ lenses.
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.
