About the London Fog LF643
The London Fog LF643 is a women's frame. This style is designed for those seeking eyeglasses in a regular size with standard proportions.
This frame measures 55-17-140: the 55mm lens width is a regular fit, the 17mm bridge is average for this lens width, and the temples are 140mm. The lens width determines how much of your face the frame covers from side to side, while the bridge width affects how the frame sits on your nose. Compare these measurements to a pair you currently wear to determine if this frame will fit similarly.
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 LF643?
It comes in one size, 55-17-140. If the first number on the temple of your current glasses is 53–57 mm, it will fit you in a similar way.
Is the LF643 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 colors does the LF643 come in?
It is offered in 2 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.
