About the Ray-Ban RB6378F
The Ray-Ban RB6378F is a full rim metal frame in a phantos shape. This unisex style works for wearers who prefer rounded frame fronts with complete lens enclosure.
This frame comes in one size: 51-21-145, with a lens height of 48mm. The 51mm lens width falls on the narrow side of regular, while the 21mm bridge is wide for this lens width, meaning the frame sits farther from your face than most glasses with similar-sized lenses. The 145mm temples are standard length.
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 RB6378F?
It comes in one size, 51-21-145. If the first number on the temple of your current glasses is 49–53 mm, it will fit you in a similar way.
Is the RB6378F good for progressive lenses?
The lens height is 48 mm. That is deep, so there is plenty of room for progressive, OmniLux® NAL® and iLux™ lenses.
What is the difference between RB6378F and RX6378F?
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.
