About the Ray-Ban RB5431F
The Ray-Ban RB5431F is a square-shaped frame made from acetate in a full-rim construction. This unisex design works well for those seeking structured, angular frames that complement round or oval face shapes.
Available in one size: 54-18-145, with a lens height of 40mm. The 54mm lens width provides a regular fit for most wearers, while the 18mm bridge is average for this lens size. To compare with your current glasses, check the three numbers printed on the inside of the temple—these measurements will be similar if your frames fit comfortably.
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. Ray-Ban case included; one-year warranty against manufacturer's defects.
Frequently asked questions
Which size is the RB5431F?
It comes in one size, 54-18-145. If the first number on the temple of your current glasses is 52–56 mm, it will fit you in a similar way.
Is the RB5431F good for progressive lenses?
The lens height is 40 mm. That is deep, so there is plenty of room for progressive, OmniLux® NAL® and iLux™ lenses.
What is the difference between RB5431F and RX5431F?
Nothing in the frame. One is the engraved code and the other is Luxottica's catalogue code for the prescription version. We list both so it matches your optician's paperwork.
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.
